HX STOMP Discoveries and Disappointments... Blocks....and Surprises- my experience

Recommended Posts

So-bought an HX Stomp.  I watched all the videos. I watched others building presets. ... I experiment with some IRs and purchased some guys presets. I get pretty comfortable with how to operate the HX Stomp.  I think I can use any effect up to 6 blocks with any of the effects and amp modelers meaning total flexibility with up to 6 effects.  I was disappointed to find that this is not true.  So depending on the Amps and Amp/Cab combos I select etc...  when I go to choose other effects-  sometimes- many are grayed out and not available.  

 

I basically worked hard to create  one preset chain where I could make 3 snap shots that have 1. Clean, 2. Bluesy clean with a little gain, 3. high gain for leads but with typical modulation effects to turn on/off.  I have a particular sound in mind with the tone - so I am off trying all the different amps and speaker combos.  I love some of them I hear.

 

My thought was I will find an amp and a speaker combo I love (with clean, medium gain and heavy) and then will add chorus, flange, delay, reverb at the end of my chain and will turn those on and off via a small midi controller I have. I researched it.  Tested it - yes I can control the blocks via midi- Yes- I can control the snap shots via midi, Yes- I can control the  parameters on the effects like delay mix and volume with my expression pedals, so far so good I thought...

 

So this all sounds reasonable right? ....  chorus flange delay reverb= 4 blocks..  That leaves me 1 block for Amp/Cab combo, and a 1 block for a Dist. in front of the amp  if needed for more gain.  

 

Guess what...  It does not work exactly this way.    

 

I go to  build my pre-sets, I find an amp/cab I like and I put it in second in second position.  I then dial in a clean sound that I love for that block.  Then I play with the gains on that amps to see if I can get a great distorted lead sound on the amp alone.. so I can use my expression pedal to high gain it.  In many instances I cant so I then I add a distortion pedal in front of the amp in first position to get that beefy gained sound I love = 2 blocks.   Then I go to add the modulation effects to add (Chorus, Flange, Delay, Reverb) and then the surprise hits me.  

 

Many times effects I want and want to try are greyed out.  Not available.  Cant get a Spring reverb sometimes.  Cant get a basic chorus in other instances. Sometimes entire effect categories are grayed out. What the heck- that was not mentioned in the manual. 

 

Seems like it may have something to do with what amp combos I select in what is available or grayed out- not sure.  Yes there is something I can always select for 6 blocks but guess what- is is not the things I always want or need.  The things I want and need are often grayed out. Super frustrating to not have total flexibility with those 6 blocks.  I researched the crap out of this and this was not mentioned in the manual or if it is mentioned it is worded in a way that is not obvious.  

 

6 blocks would have worked for me if it really allowed me to chain "any" 6 effects together but there are way too many limitations that are grayed out each time I found a base sound I like..

 

I do love the sound but this is a bit too limiting unless I am doing something wrong.

 

 I know people will say get the full sized Helix but for me cost and size is a the issue- mainly size.

 

Someone please tell me I am doing something wrong.  I want to love this unit.  I am so close.

I hear what you are saying, and I do understand why you were under the impression that you could use any 6 blocks, rather than up to 6 blocks.

 

I'd often see people posting here about running out of DSP, and didn't realise what they meant until I got to the point where I began to see some options were greyed out when I wanted to add a block. Then I understood!

 

I don't have a Stomp (I plan to get one as a backup for my LT) but I have read the manual, and it does have a section on DSP allocations and how it affects what you can choose - look at the section on Dynamic DSP.

Thanks as with any new thing there is a learning curve.  I did not know what DSP was or that that meant and that was related to this surprise I discovered.  Now I know that DSP is like RAM memory on a computer (I think).

 

I am not going to give up yet.  Scott at https://www.scottminchk.com/ has some videos and patches on you tube  that he is working on where he has carefully selected the effects to do what I want to do to cover some typical covers out there with gain & clean  channels and typical effects.  I am hoping with his chains and some luck in finding a tone that is not a DSP hog so that I can chain more modulation effects,  I can keep the Stomp.  

 

Love this forum.  It has been very helpful in my transition to Helix.  That full sized Helix sure looks tempting after running into this DSP wall but falling in love with the some of the models and sounds!

Apart from the amp and cab models, the Spring Reverbs and the stereo HX reverbs are probably the most DSP-intensive blocks available. Some of the delays, especially the tape models, are relatively DSP intensive as well.

 

Take a look at the Excel file here. It gives a good approximation of the DSP use for each amp/cab/effect model.

Not going to lie- I know it is my responsibility to research before I buy- but for a newbie I missed it.  The last thing I always do is add modulation after I dial in the tone.  So I got midi figured out first- took me hours, check, then heard the tones check in the model, figured expression pedals check.  - Mistake I then Velcroed it to my board. Then went to simply add the modulation effects and I was like WTF.- grayed out...  If I return it I hope that the velcro removal comes off cleanly so I can get a refund.

I love the Helix and the HX-stomp but while we are talking about some of the HX-stomp shortcomings:

 

I realize those high-end computer chips are expensive and giving us one in a $599.00 piece of equipment seems like a good deal and a compromise  to get the cost to this price-point. 

 

However, isn't memory cheap enough that the engineers could have given us more than one set list?  What if we are in two bands with distinctly different tones for each band, or we play two different kinds of  music styles or have two different rig set ups?

 

The POD 500 and the Helix always accommodated multiple set lists, I wish the HX-Stomp did too.

You're returning it? Let me ask you this... Is there anything else with a similar footprint that can do what it does? Yes, I understand it can be frustrating to have your expectations and reality differ, but I think if you stick with it, you'll learn to work within the limitations of the unit. I mean, it still does an awful lot in a tiny package.

To be fair though, this is the kind of thing that is nearly impossible to the adoption users to find out unless the company explicitly states it, and in this case Line 6 didn't say that. 

 

I was under the same impression that you were. In fact, based on some of what they said, my assumption was that Line 6 chose such a small amount of blocks in order to ENSURE that you could always use all 6 in almost any situation. In my case, I was specifically comparing the Stomp to the Headrush Gigboard. Now, first, the Gigboard is still fairly larger than the Stomp AND it is $50 more expensive.  I also feel like Line 6's Helix sounds are better. To its advantage though, it has the exact same processor as the full blown Head rush and as far as I know can play every block the bigger brother can.

 

I made the conscientious decision as a consumer to choose the smaller block numbers because I preferred the Line 6 environment, but finding out that in many cases 6 blocks was not going to happen . . .when six already felt like a compromise, was one of the few letdowns I've had with the device. I still think I would have chosen it when compared to the Gigboard, but I'm not as confident.

 

Anyway, I don't blame you for being a bit miffed. I'm using it primarily for DSP expansion so it still does that. If you're using it for a full rig it's harder to deal with.

Just to be clear, the Stomp uses the same processor as the Helix uses. It's just the Helix has two of them, whereas the Stomp (and the HX Effects) only has one. So if you hit the DSP limit with six blocks on the Stomp, you would hit the DSP limit on the Helix if you tried to create that signal path on a single processor path. You could add more blocks on the Helix by dropping down to Path 2...

I think my problem is- don't laugh- I am coming from BIAS FX and BIAS amp on the IPAD.  With BIAX FX I could run 2 paths with almost unlimited effects and amps and sims on/off in each chain.  The problem there is I could not trust the IPAD live with some very occasional tech issues I encountered and I could not chance that live.  So this was my first move in many years to return to a multi effects pedal - prior to that many years ago I had the Line 6 M9 that I had success with but one button crapped out on me and it was not cost effective to fix so I moved to the PAD.   Anyhow - I am not giving up on the HX Stomp yet.  I have 45 days to figure this out.  I do not need much for the songs I play so I am hopeful I can find an amp sim I love and then create more carefully thought our presets to match the songs rather than one chain that I used to use in BIAS FX for multiple songs.

Are you 100% positive that there weren't some processor compromises?  Because my understanding is the full Helix can have at least double the number of blocks on one signal chain without even going into the second path. I realize this could mean it was tapping into the second DSP, but I thought I'd heard of dual signal paths with 20 or more blocks (I don't own a Helix so I could be completely off base here). The idea that the Stomp hit a brick wall at 6 with some pretty simple choices seems crazy if it's half the processor of the full unit.

I have a full Helix and a stomp, if you want to send me over a list of the exact blocks you used, I can tell you if it would have worked in the helix in one path without running out of dsp. Cause, now I am curious about that as well. I can get a lot of stuff into one path on the Helix without hitting the dsp limit.

Yep... 100% sure. All Helix products are using the SHARC ADSP-21469 chip. It's just the Floor, LT and Rack have two of them, and the HX Effects and Stomp have one. BTW, the Fractal FX8 uses a single SHARC ADSP-21469 chip as well, just for comparison's sake.

 

There are simply some amp and cab models that are a lot more DSP intensive than others. Sometimes if you put in an amp, a cab, and the '63 Spring Reverb model, you won't have left for much else at all on a path. With some amp models you can have a lot more. On the Helix itself, you can have up to 16 blocks on a processor path, but it's not like you can fill them all up with DSP-intensive blocks. It's really more for the sake of routing flexibility than being able to max out blocks. If you create an effects-only Helix patch, you can load a lot in there, but unless you want 16 EQs in a path, you wouldn't be able to use all the blocks.

Okay, if you're interested, I would be VERY interested in testing the following because my Stomp gagged on a hairball at 4 blocks which is way earlier than I thought it would.  Here's the chain:

 

Obsidian 7000 (Stereo) >>>> Cali IV Rhythm 2 (Amp + Cab) >>>> Multipass Delay (Stereo) >>>>> Harmonic Flanger 

 

At this level there were hardly any 5th blocks it would let me add, and six blocks were dead in the water. I'd be very interested in finding out if this challenges the first DSP of the Helix.

If the Harmonic Flanger model is stereo, yes, there are some greyed out effects after that. The only available, for instance, is the mono version of the Ganymede. One thing is that a stereo uses almost twice the DSP of the mono version, so putting a chain of stereo blocks together we'll eat the DSP up faster.

 

I actually recreated this chain both in my Helix and in the Stomp and had them both connected to HX Edit at the same time. Since HX Edit has multi-device support now, each has its own window. When I compare the lists of effects that are greyed out on each device after adding the Harmonic Flanger, they appear to exactly the same. One thing I will say is that I wouldn't say there were hardly any effects available after adding the fourth block in your example - there were more available than unavailable. That's the same in the Stomp and the Helix.

You're right.  I should have been way more careful with what I was saying with the words "hardly." It was referring to the specific area of effects I was looking at next, not the whole box, which is an important distinction.

Thanks for testing that out Phil and it's good to know. The unit I lived on before this was a Firehawk 1500 which largely forces you not to run into DSP issues, and before that the HD 500x, which I did sometimes run into DSP issues but it was too far back for me to remember how much or often.

 

The Stomp is my first Helix and I'm admittedly comparing it to an imaginary perception of what a full Helix would be. It's also important to point out that the chain I tried to max it out with above is just a hypothetical chain, there are many DSP reduction things I could have done if I wanted something like that to keep the Stomp from hitting its limit. 

 

I bet the longer I use the Stomp the better I'll get at managing its resources and doing with it what I want.

I have an Amplifire and it is quite a bit more powerful in some regards. In others the Stomp is better. I would definitely say they are comparable products and if I could only keep one it would not be the Stomp. The Amplifire is not big at all very close in size to the stomp and some people are likely picking up the Stomp to experience Helix modeling for cheap rather than for the size. The Headrush Gigboard might be a great option for those kinds of folks who want top quality sounds without the full cost of some bigger units, too.

 

The Stomp is extremely cool but not the only game in town.

The Amp&Cab Block renders any Stereo FX before it as Mono. So, why use the Stereo Obsidian 7000? 

Note: I'm not at my Helix at the moment to check if a Mono version of the Obsidian 7000 is offered. If a Mono version Obsidian 7000 is available, it would free up about 1/2 the DSP allocated to the Stereo version.

This is true. That said, no, those blocks would not tie up the first DSP on the Helix.

 

In my current preset I have these blocks on paths 1A and 1B (they are all mono versions):

 

Para EQ - Simple Pitch - Legacy Phaser - Legacy Analog Flanger - KWB od - Teemah! - Scream 808 - Wah - Bubble Vibrato - 10 band EQ - Tremolo - Volume

 

For the heck of it, I just tried adding a stereo Chorus, stereo Trinity Chorus, and stereo 70s Chorus. That's when some blocks started graying out for me. On the first DSP. So about 6-10 stereo blocks depending on what types of blocks, and estimately twice that amount of mono blocks is possible on one DSP chip.

A really good friend used to work for Positive Grid, and I have nothing bad to say about them, but...

  • Helix's models use up notably more instructions per second than BIAS models
  • Helix's full throughput latency is significantly lower, and is designed for real time performance and control
  • Hardware DSPs are not CPUs

Line 6 has been very careful to always say "up to 6 blocks." If a "6 blocks" instance snuck out, I apologize, and will make sure we change it.

 

Also, HX Stomp isn't underpowered as much as it's... nuanced and flexible. The alternatives are all way more egregious:

  • Provide fewer block locations AND/OR
  • Create fixed "chunks" where a preset allows for only one of each type of block AND/OR
  • Only support specific and limited groups of effects (Distortion+EQ+Delay or Distortion+EQ+Reverb but not Distortion+Delay+Reverb, etc.)
  • Completely remove any models that are too DSP-intensive to fit AND/OR
  • Strip the models way back so they fit, but don't sound nearly as good AND/OR
  • Other stuff, like distortions and dynamics are always mono, cabs are always single, amps and cabs are separate blocks, etc.

Also note that if we ever add polyphonic pitch models, running out of DSP will happen quicker and more often, as they take up a LOT of horsepower.

 

I have an unfinished blog about fixed vs. semi-fixed vs. dynamic DSP allocation if you'd like to know more. PM me your email and I'll send it your way.

Yep 8 blocks would be great volume pedal use a lot of dsp, looper ? Simple mono verb ? something in the software could show "cpu limit can't add effect too". So eight is a cool number. More presets doesn't use DSP, so why only 128 ???

Is there/could there ever be a SHARC processor upgrade for the stomp for those that would pay for it if it was sent to L6 to have it done??  A newer/faster one?  Would it solve any of the block/dsp limitations?

The Stomp could already handle considerably more blocks than the six they allow it to. They chose to limit it to six not based on DSP limits. 

 

As for is it possible, of course . . . but that drives up the cost of the unit, and if it gets too much pricier you're in LT territory.  I don't think it will happen.

I get that... I’m talking as a custom upgrade for those who put a premium on keeping the footprint down.  I’d ship mine back to L6, and pay the cost if they would do it.  The SHARC chips themselves aren’t really that expensive.... not sure how much labour is involved or if it involves changing some coding.

 

I’m hitting the dsp limit before I run out of blocks to do all that I want

IDK but perhaps the decision to limit to six blocks was based on DSP limits, as it represents a reasonable 'typical use'. Since some amp and fx choices could max you out at below six, setting the block limit any higher would result in even more aggrieved customers.

Maybe ... and maybe they did think that way, but I think the they'd get way more buy in letting it do what it's capable of than artificially cutting it off.

I'm gonna say the same thing here I said with the HD series. If you're going to advertise that it does 6 effects, it better do six effects or its gonna look like somebody lollipoped up. 

 

Like the number of speakers in the Firehawk 1500? Get used to it- tis the way of "Marketing" these days and Line 6 is far from being the only one that does it.

Am I agreeing with the way they all do this? Hell no, but I also know the difference between *hit and shinola.

There are lots of ways to reduce DSP demand without significantly sacrificing tone.

 

The first thing to consider is the context. If you’re playing solo electric guitar, then you need a lot of tone options and control. Don't use HX Stomp for this, use Helix. But if you're playing in a band context, then the focus should be the song and the mix, not necessarily your individual tone. In a band/mix context, all the complex  tonal subtleties from complex blocks and patches either get mostly lost in the mix, or can actually degrade the mix because they make an overly complex sound that competes for too much space or is indistinct and doesn't cut thorough. Less is almost always more in a live mix when it comes to effects.

 

 The next is stereo/mono. Stereo blocks take twice as much DSP as mono blocks. So avoiding stereo can save a lot of DSP. Stereo sounds great by yourself. But in a band/mix situation, it offers little benefit. If you're using a stereo backline, then you might hear the stereo, but your audience won't - the speakers are just too close together. If on the other hand you're putting your stereo guitar through the FOH, only a few select people in just the right position will hear it, that's why most FOH systems are run in mono - to ensure everyone hears the whole mix, no matter where they are positioned in the venue. If you really need stereo and lots of blocks, use Helix not HX Stomp. But most of the time you might find mono is just fine and can in fact help clean up live mix issues. Also, if you do use stereo, there's no point in using a stereo block in front of any mono block (e.g., any amp model) since it will get summed to mono anyway. That's just a waste of DSP,  and the summing a stereo block to mono can have a negative impact on it's tone.

 

Next there are ways to eliminate blocks, not just to get under the 6 block limit, but to preserve DSP. The OP introduces a couple of good possibilities. Chorus and Flanger are really quite similar effects. The difference is in the length of the delay and amount of feedback. With the flangers in HX Stomp, there's often enough parameter control to produce a pretty good chorus tone from a single block. You can switch between flanger and chorus by using a footswitch or snapshot to change the parameters and save a block.

 

Another great example is distortion. The OP tried to get the distortion from the amp model but wasn't successful and had to add a distortion block in front of the amp. Often the reason amp distortion is insufficient is because there's not enough tone shaping after the distortion. Most distortion blocks provide tone controls that shape the voicing of the distortion. This can be critical to achieving the right tone, and is something where amp blocks are typically more limited. But with HX Stomp, there are lots of ways to voice distortion with an amp block that can provide the control you need without requiring an additional distortion block. You can control up to 8 parameters with a stomp footswitch, or 64 parameters with a snapshot. I prefer footswitches because they are "stackable". With HX Stomp's 3 footswitches, I can control any combination of three things. With snapshots, you only get three different snapshots.

 

For distortion voicing in HX Stomp, I use a single footswitch and set max and min values for amp block drive, bass, treble, presence, and cab low and high cut. Drive (and maybe master) control the amount of saturation. Bass and treble are used for EQ into the the distortion, reducing bass at higher drive settings to reduce mud. Presence, and cab low/high cuts control the voicing after the distortion, lowering the cab high cut to reduce fizz and ice pick. I've found with a little work, you can get really great distortion tones out of just amp models and one footswitch.

 

Finally there's block choice. Sure there are some great effect blocks in HX Stomp that sound really cool and have a lot of control. But these complex blocks tend to use a lot more DSP. You might find that a simpler block produces a similar tone but at much lower DSP usage. In a band mix, the simpler block might actually sound better.

I'm only quoting part of it but I wanted to say I actually whole heartedly agree with the whole thing. 

 

Now, without a doubt I hope they open up the Stomp to use as many blocks as DSP will fit, BUT with the Stomp it's still always going to be about efficiency, and with tricks like the above you can do amazing things.  

 

If you have a small and cheap midi controller and a dual footswitch, it can get even crazier. I tend to combine snapshots with additional parameters being controlled by the midi controller. It really takes you far.

Great post from amsdenj. I have Helix floor but I still use an old POD HD for holidays*, plugged in to a Roland Cube Lite sprouting Beyerdynamics. Edit is via a Dell notebook. A bit Heath Robinson, but it has served me well for a number of years :-) 

 

But it's long in the tooth and I'm going to get a Stomp. I know I'll be fine with Stomp because I'm a follower of the 'fewer blocks, better tone' school :-) I also understand the DSP limitations from the perspective of a Floor user and to me, at least, they don't present a problem. So Floor it will be, and bye bye to that  fiddly knob interface for HD Edit... 

 

I know that it is possible to get excellent tones from Helix Floor using only path A and a handful of blocks and simple linear routing. So I know Stomp will do the trick for me. Of course YMMV but I hope this is useful.

Just want to say that amsdenj's post is 1 of the most educational I've ever read about setting up a patch.  Thanks!

Is there/could there ever be a SHARC processor upgrade for the stomp for those that would pay for it if it was sent to L6 to have it done??  A newer/faster one?  Would it solve any of the block/dsp limitations?

Shoot me a PM and I'll send you my Dynamic DSP blog. It'll make way more sense than me trying to type everything out here.

At namm there was a Line 6 get together where several things coming up on the 3.0 update were mentioned. On The Gear Page this was posted.

 

@phil_m dispensation has been given and inquiring minds want to know, :)8 Stomp blocks was one?

Yes, the 8 blocks for the Stomp was the third one they mentioned.

 

So looks like 8 blocks are coming. Don't give up yet!!

Apart from the amp and cab models, the Spring Reverbs and the stereo HX reverbs are probably the most DSP-intensive blocks available. Some of the delays, especially the tape models, are relatively DSP intensive as well.

 

Take a look at the Excel file here. It gives a good approximation of the DSP use for each amp/cab/effect model.

Im looking at buying a hx stomp at the moment. I love my drive pedals so it will only be used for modulation and some other funky stuff. If im running the basic plate reverb, my amp through 4 cable method, a delay, and every once in a while chuck in a tremolo or a chorus, maybe another drive will it be fine? I might occasionally run an amp rig into my effects return or headphone/ recording out that will probably just be a marshall, a cab, maybe a reverb, a delay, then maybe 1 or 2 other pedals, usually not have 6 effects in the same preset though. I think i might run into a problem if for a particular song i have to use all the effects but i doubt i will need all 6 on at once. Do effects use alot of DSP? Mostly the line6 default reverbs, harmonic and basic tremolo and a fuzz or 2 here and there, will it effect it that much?

 

To be honest it will always be a reverb but i doubt i will ever need 2 effects on at once for the most part, maybe a delay and modulation but its mostly marshall and reverb and delay

My experience using the HX Stomp into my amp without amp models has been fantastic. No DSP problems at all, The amp/cab models are the real DSP hogs. And if you want the sound of a particular amp model you have the option of using the amp without the speaker cab and that cuts down the DSP use.  

Don't shortchange the drive pedals in the HX  Stomp. I am setting up presets that sound better than my pedals -- I have three  overdrives still on my board but one may be  coming off now and I am reassessing the way I use the other two. I run the Stomp in front of my Blackface Deluxe  or Princeton Reverb so no four cables. Works great. BTW  I use the Stomp for reverb and always on.

My opinion is that if you use the HX Stomp the way you describe you will be very happy with it. I am.
