Hi Iain,

You are exactly correct. I've been wearing blinders (call it an "extended 
senior moment").

Years ago, I now recall, I had nearly the same issue, but with CC64 (pedal 
input). Istvan Varga responded nicely to my dilemma (and yours, it seems) by 
implementing the -+raw_controller_mode=1 flag. This does what we both want.

 (In the context of our recent trolls thread, remember Istvan? In many ways 
I miss him; he was an outstanding, productive developer who had his 
*strongly* expressed issues with this group. And yes, I do know he left on 
his own accord.)

I've used -+raw_controller_mode=1 in all my MIDI csd's *for years*; for 
unknown reasons, I left it out of CsOptions this time and forgot all about 
it.

Very sorry for the noise, and Iain, thanks for your 
troubleshooting/problem-solving.

Art Hunkins

Hi Art,

What you have there isn't really to do with diskin but to do with how 
controllers are initialized to 'useful' starting points according to their 
General MIDI function. Try the code below and you will see that Volume/ctrl 
7 and Expression/ctrl 11 are initialised to their maximum level 127 - 
probably useful in a GM situation so that we aren't playing muted 
instruments until volume and expression are explicitly set. Balance/ctrl 8 
and Pan/ctrl 10 are 'sensibly' set to their midway value 64. I think this 
could be a portmidi feature but perhaps someone more knowledgeable can 
illuminate me? Personally I find this not so useful as I have no interest in 
General MIDI and would prefer that this initialising was not done. Can it be 
removed / filtered out?

Iain
