If this is on a POD HD500 then no. Need to be more specific of what gear your using. You may have a dirty switch that needs replacing or some kind of grounding issue with the pedal. Until I know more about your gear I cant say much else.

lol, I like your Sega analogy. Made me chuckle. What adverse affects are you assuming with your suspicions ? Are you worried theyl stop supporting the HD X firmware wise ? Cause eventually all older models will be put to pasture, that's how it is. I don't think this is happening quite yet tho. But seeing as tho the HD X series is pretty much the same thing as the HD series, they might get abandoned at the same time. This would very well depend on wether they share the exact same firmware. EG: POD HD Pro Vs POD HD Pro X. If they don't share the exact same firmware, They wont abandon it for a while yet id say. Download both firmware's and compare the file attributes, version numbers, file size ect. That would clear that part up.

+1 on the USB cable and port. You might have your sampling rates set wrong in the windows mixer devices section. This can cause all sorts of suprises and even prevent any output. Check em out and make sure the POD is set to 16bit 48Khz in both recording and playback sections in windows aswell as the POD's internal sampling rate settings. This seems to be the least problematic setting. Also, I would check the impedance of your headphones with a multimeter. Lets assume your headphones are rated @ 32ohm for the moment. Make sure both left and right are of equal resistance, if one headphone is a different resistance to another by a certain amount, say about %10 +, This would indicate a problem. If they are equal and between 16 to 48 Ohm then id say your headphones are just fine. If they are equal and below 16 Ohms or above 48 Ohms, then this would indicate an issue with them aswell. This would definately rule them out as the cause if you try testing them in this way. The most dreadful possibility this might be with it is that you did damage to the POD's internal headphone amp. Sometimes the simplest of things can be over-looked when it comes to rare and unique faults. Hope this helps.

Hi. Its not possible to directly control any of those amps like that with the POD and vice/versa. You'll have to control both separately unfortunately. Line6 may have an amp that could do this easily via FBV port. There are some instances where you can achieve this with certain combinations of amps/MFX/Switches, but more often than not, this would require a modification of some kind to keep the switching lines compatible with the device your trying to control. Boss seem to be the most thoughtful with this. They have switching pedals that can interface with alotta different amps and MFX pedals and even synths. EG: The Boss FS-6. FS-5U. and the FS-5L. I doubt any of those will control the POD via the EXP.2 socket. Pretty sure Line6 just made this socket exclusive to expression pedals only, where as other manufacturers have made this socket a dual purpose one that can have either an expression OR a switching pedal connected to it. But not both simultaneously. Hope this helps.

Damn.

Ahh I vaguely remember this, are you saying I can build FX and amp sims from the ground up with that SDK and have it transferred to my HD Pro ? This would be awesome. Not so interested in that stomp tho.

Admittedly, I should be fully up to date with this so maybe I should start reading myself and catch up. Not the basics, just the cutting edge stuff.

You may have seen this before but if you haven't you could learn a little more about FRFR here. http://line6.com/support/topic/1494-advice-from-frfr-players/

Thanks for the point lol, I needed to get outta the red !

Depends if you consider a swing of +/- 3db to be flat. And really +/- 3db is a total of 6 db between peak and trough. I've seen speakers with less than that. Also, that spec doesn't tell you at what frequency points it peaks and troughs at. this is why you should look at the graph. Not sure what they officially spec the FRFR db at. But note that for every db less and closer to a perfect flat-line (which is impossible in the real world) will show substantially in the final cost. Put it this way. If those alto's where truly FRFR then alto should be flaunting this claim all over their specs and marketing it as its primary selling point.

You weren't connected to PCI or PCI-E soundcard at the time by any chance ? Easy enough to swap out an offboard soundcard, not possible with onboard.

When assessing speaker specifications they will usually also supply a frequency response graph from 20hz to 20khz which plots out amplitude vs frequency of the speaker. The more horizontal and flat the graph line is between 20hz to 20khz, the better. This is what they mean by flat response. Always look at them graphs first. Graphs tell %95 of the story. Specs tell %4 of the story. Ears tell %1 of the story. Specs expressed in figures like you posted won't tell you everything. The graphs are more detailed and comprehensive.

Ideally you'd want an interface capable of 96khz sample rate. The POD goes this high, might aswell put it to use and pay the little extra for an interface that operates at that sampling rate. Personally, I can definitely hear the quality difference between 48khz and 96khz, think of future proofing too. The less AD/DA converters in-line, the better. Something like this perhaps ? http://www.roland.com/products/en/UA-5/ just a random find. Supports both SPDIF input and output @ 96khz Coaxial (RCA) and Optical (TosLink). MAC compatible drivers. As for your cable. All you need is a single RCA lead and a 1 dollar BNC adaptor at one end, Done. Cable quality isn't such a big issue with SPDIF as the signal is pure digital.

lol @ give up, Mesa Tri-Axis for me thanks :D And most definitely the 5150 or 6505. Wouldn't it be nice if they gave us an SDK to work our own magic with and create new FX and amp sims, id rather vote for that !

Only way to truly prove your theory would be to run your POD through a spectrum analyzer and oscilloscope with each firmware version. Not the kind of test equipment people have just laying around. Alternatively, you could get software to analyze whats going on via soundcard line-in. I use iZotope Ozone 5 for spectrum analysis if I don't want to use hardware for this and a signal generator connected to the POD's input set on sinewave @ 100mV. No average Joe is going to go to this much trouble. Just saying what it would take.

I don't know to be honest lol, never owned alto gear before. But, if you go to his link and watch the youtube clip, Im pretty sure they talk about its flat response, just sayin. I'll even dig into the support pages to see what they say. Well I just went back to have a look and seems I was wrong. FRFR wasn't mentioned in the video and FRFR wasn't stated in its product overview and specifications. Not even the manual mentions FRFR. They only mention FR (full range) But they do make them in both active AND passive versions. I don't know radatats, he could be onto something there...

Maybe bvaladez74 accidently bought a chinese knockoff with the tweeters missing...

Another statistic, with a twist.

What exactly do you mean by "alter pitch by a tone" Do you mean just standard pitch-shifting or ?

+1 on the sampling rates. I would also look into your ASIO driver's buffer settings aswell as they can cause clicks too if not set properly. Both these settings need balancing out till you find an optimum.

Excellent post, this gets me to the core of the HD Pro's signal routing. Thanks a bunch!

Ahh, thanks jandrio, seems I missed that in the 10 thousand page manual lol. Still begs the question of wether I can do this without the amp sim tho... Or maybe I could do this with dual amps with the mixer set properly ? I prefer to achieve this with amps if possible.

Yeh I always keep the FX Loop block after the mixer as it seems optimal there and that takes care of the Post Amp stereo path. The stereo path before the amp sims is what looking at now. Ok lets say hypothetically I wanted to achieve this configuration. Guitar > External FX (Stereo) > HD Pro Line input (Stereo) > Internal HD Pro FX (Stereo) > HD Pro amp sim (?) > FX Loop Send (Stereo) > External FX (Stereo) > FX Loop Return (Stereo) > Internal HD Pro FX (Stereo) > Output (Stereo). What im trying to achieve here is a perfectly symmetrical stereo path from the beginning to the end of that entire chain. What im not sure of is how the amp (or amps) sim will effect that stereo path once the signal reaches it. To pass a stereo signal both in AND out of the amp (or amps) sim, would I need a single amp setup for this or dual amp or would I have to completely remove the amp sim stages to preserve the stereo image from the line inputs ?

As I said.. "Accessing setlists directly from the POD is also possible by pressing once on the dial on the left side of the LCD." Press down on the dial once (it functions as a button too) Then rotate the dial to change setlist. Theres a label directly under the dial that says *press for setlists* When you've chosen the setlist you want with the dial, press *enter* to select it. lol took me a while before I figured that out aswell. Hope this helps.
