[linux-audio-user] restricting MIDI channels

[Dave Phillips]

Greetings:

  This is a precaffeinated message. You have been warned.

  I own a Yamaha MJC8 MIDI patch bay. It's very nice, but alas, it does 
nothing more than route connections. I would have preferred a 
programmable patch bay. Such devices included many amenities for the 
MIDI user, including channel control, scene memory, autoscanning 
hardware, etc. Personally, I'd like to see such features in a software 
MIDI patch bay. I'd also like to see something like a software MEP4 (a 
MIDI event processor box), but again its features could be incorporated 
into a programmable patch bay.

  At this time, it's either all or nothing with MIDI channels. Very 
frustrating when I want to use my TX802 on Ch 1, *only* Qsynth's drums 
on Ch 10, and ZynAddSubFX on Ch 5. The synths do in fact include their 
own channel selector, but the 802 is multitimbral and I often leave it 
in an 8-channel (8 instruments) configuration. So if I have a connection 
scene that includes Qsynth and the 802, everything on those eight 
channels gets played by Qsynth, but I don't want that to happen.

  So, can it be done ? I tried using holborn's SoundFontCombi but 
couldn't get it to keep the settings I made. Every time I started 
playing a sequence it would flip back to its original state. Sigh...

Best,

dp
