Hello!
12 Step is a great piece of gear. I use it with Ableton Live 8 with a set of softsynths. I use it as my master controller sending program change messages for all the virtual dudes and the real dudes (a Digitech RP355 Pedal) so, I just change the preset in 12 Step and voila! The set is ready for the next song. I also use the 12 Step as a sample trigger. In my particular work as a multi-talented musician (I play keyboards, guitar, bass and vocals) it would be great if you can add more parameters for edit, I mean, MIDI channel and program change messages for example. There are cases where I need to change a preset in the guitar pedal at the same time when I trigger a note. The solution now is do a little tap dance or use dummy clips in Ableton, but it will be great if you can add that option to the 12Step.
Well, as I use the pedal new "wishes" may appear...
