You can easily assign midi controls to the bypass of each effect. If you need lv2 effects you could try lv2rack (I don't use it alot though and can't tell if you can assign midi, but I would suspect so) If you need to this with a mix of standalone software (rakarrack and guitarix come to mind) you would need something midi-controllable to put up the signal chain to split your signal. There are probably easier [and better] ways to do this, but with a bit of tinkering I came around with this: in jack-rack you load "mono to stereo splitter" and "simple amplifier", you set the gain of the amplifier to its minimum (-70 I think). Now, when both are enabled, the signal only comes out of the splitter outputs (mono_to_1-1 and mono_to_1-2) and when both are disabled the signal comes out of jack-rack's outputs. You then only need to assign the same MIDI CC to both "enable" buttons and you're done. Quite a hack, but it should work best wishes, renato _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
