Solo On Trasition already exists...

But the point victimofconspiracy mentioned is interesting. You know, those "mute on ***" options are for realtime playback, that's right. those aren't necessary on the generel tab. BUT... The channel state (muted or not) is
saved in the module files...
Muting a channel is an option like
Surround! I hope that you get my message. Muting doesn't have something to do with patterns but with genereal settings which are stored in the song.
