Something similar happens to me!
Please, check my post
I have the same problem, but actually class and triode/pentode seem to change OK. What does not sound different is the voicings.
Have you found the reason?
I noticed the same problem here.
It changes the ligths, but the sound doesnt seems to change!!
Some clue about this problem?
I am using the GSC-3 controller, and I am pretty sure that use the CC's number and values correctly.
If someone have some news please post here, if I find a solution I will do the same way.
Cheers from Brasil.
Nope, I am in the normal volume mode.
I've opened a ticket for support on the Line6 webpage and received an answer that I think is good to everyone here to know.
Currently, these MIDI CC's are toggling the Negative Feedback Loop Topology in the amp, but not the full voicing as described in the manual.
The manual is incorrect in saying that these MIDI CC's will change the voicing at the moment.
We are currently looking into this to see if this behavior can be changed in an update or if we would need to revise the manual to contain a correct description of what those MIDI CC's should do.
As you can notice IT REALLY HAVE A PROBLEM WITH THE MIDI CC WHEN IT COMES TO CONTROL THE VOICES.
I think good part of discussions among the users about the quality of the sound of the POD HD versus the DT25/50 is all about this issue too,
because what I could understand (correct me if I am wrong please), is that neither the POD HD can really change the VOICES, it only changes the LIGHTS of the panel.
For now I am trying to organize some presets on the GSC-3 accordingly to my needs. For example: use just 2 Voices at a time, setting it manually on the amp on channel A and B, and than on the GSC-3 control the other parameters.
I manage to control everything apparently, except for the Voices.
It is really a shame can not use all the possibilities of this wonderful gear. Hope in the near future it can do what it promise it would be.
