Hey Korhan,
I've been using a portion of my a100 system for live free improvisations. I have a suitcase
filled with modules. I usually make two patches before the improv. session starts. I use a A-
138 mixer to switch between patches. I use a Roland footpedal to control the main level of
my output. During the performance I also mainly change my patches and/or create a third or
fourth patch. It's mentally quitte tiresome but it can be very rewarding..
Have fun!
