It would be nice to have native Stop/transition FX without the users having to set them up themselves in the midi mapper.
And pressing the stop FX shold disable any FX that are current on at the time. So I can have multiple FX running during a build-up, hit the stop FX (dely, spinback, vinyl stop etc) and all the other FX get disabled and song continues as normal without the user having to turn off all the other FX first. Basically how the RMX-500 works.
