Helix and PowerCab+

I have a Helix lT and a PowerCab+ .  I recently got a AES/EBU cable to connect the Helix and Powercab.  I thought that with that cable I could use the Helix to change speakers as I change amps on the Helix.  I have read here that in order to do that I need to use MIDI cables then others have claimed that the Link cable can do it all.  The main thing I'm looking for is to have speakers change to go with what I have selected on the Helix.

I do concerts and sometimes the back up bands can be placed in tight quarters.  I have to go back in forth with electric to acoustic guitars and I need the PowerCab+ to be able to go from a Celestion speaker to Flat response for the acoustic.  Does the AES/EBU cable have that ability

You certainly can do what you want with the AES/BEU cable. The only thing a little confusing about it is that the Helix doesn't switch different presets on the PC+.  What it does instead is it allows you to select all of the PC+ settings from the Helix preset.  This can be a little confusing, because the display on the PC+ won't be up to date.  

 

Note that you did need MIDI for this before AES/BEU was fully supported in firmware.

In HX Edit, if you select the Output Block, then select the Powercab Tab, you can set the Powercab speakers for that preset. You can also assign speaker and FRFR Mode changes to Snapshots.

This works with the AES/EBU cable. MIDI cables are only necessary if you want to change Powercab Presets or control Powercab settings using MIDI commands.

NOTE that when using the AES/EBU cable you should use a Powercab "NEW PRESET" or a Powercab user preset set to LF FLAT. This is due to a problem with the HF driver not switching off in the LF FLAT/RAW and SPEAKER modes when switching using AES/EBU and a Powercab Preset set to FRFR.

I think it's a bug, in that, if you're controlling the Powercab from the Helix, the settings should be divorced from the Powercab Presets.

At present, you can shut off Helix control when using PC Presets via MIDI, but not the other way around.

I am hopeful of a Powercab update that addresses this and some other bugs when using two PCs.

Hopefully, the update will include an improved version of Powercab Edit, and a MUCH better manual!

Here is a slightly different question on the topic of PC+ and mode switching.

I have 2 PC+. I want independent control over the speakers. Example

 

I want one to be the internal speaker and one to be FRFR or

*One to be FRFR and one to be LF Raw or

*One to be LF Flat and one to be LF Raw

 

You get the picture.

 

It appears that you can select speaker 1 or speaker 2 or speaker 1+2 linked together.

 

this function doesn't seem to do anything via L6 link.

 

If I try to set one speaker to do one thing, it applies to both speakers regardless if the speaker 1+2 link is engaged or not.

 

Thanks for the help

Are your speakers PC112+ or PC212+?

IIRC, your problem is a known issue on the PC212+, but not on the PC112+.

In any case, there's problems with L6 Link that L6 has so far refused to deal with.

Or even acknowledge.

Contact support and see for yourself. Good Luck!

As far as many of us who have been active about this on the forums can tell, the Powercab series is abandonware.

I took a minute to look into this, as I've never tried to use my Powercab like that.

I have the PC212+ which, AFAIK, in your situation works the same way as having two PC112+.

You can have different IRs on each speaker in FRFR MODE or USER IR MODE.

You can have different emulations on each speaker in SPEAKER MODE.

But the MODE itself applies to both speakers.

Its interesting you see this as a bug.

 

This behaviour is the same on any two midi devices .  If you edit a parameter that parameter will change but the patch will not change its name.  As an example, if I have a mixer patch and connect a MIDI controller I can change parameters in the mixer from the controller but the patch will not change (and devices vary as to whether they remember those changes on power up).  Unless you save the Patch, the changes will be lost.

In that mixer example the Patch name might be "All Muted", and the mute parameter active for all channels.  On the controller I can unmute channels, but the name of the Patch will still say "All Muted".

I dont see this as a bug.

I do however have a PC Patch labelled "Helix Control" so I know where the "Master" controls are.

I don't think that we're talking about the same (or even related) issues.

 

The post that you quoted was related to an issue where if you use L6 Link from Helix to select a Powercab Mode wherein the HF Driver should be OFF (all modes except Flat/FRFR and UserIR) the HF Driver would not (consistently) turn OFF, rather it would remain in the state invoked by the PC Preset. I call it a bug (and I'm not alone in this) because if the Helix REMOTE setting is set to PRESET that should override the Powercab's Preset. It almost seems as though the Powercab's tiny brain can't decide who's in charge - it's preset or the Helix L6 Link settings!

 

This has nothing at all to do with Preset NAMES. The only thing that can change a preset's NAME is if the user goes in and manually changes it.

Well, I suppose a very technically adept person could write some fancy script to do it, but that's a whole 'nother subject!
