I am still fairly new to this amazing software and I have had a lot of fun so far experimenting and creating patches that work as modes of improvisational composition. Anyway, I have 4 arpeggiator patches that each have specific presets that are used mostly as key changes. I would love to trigger these presets, or cycle through them, externally, either in the Metasurface or through a MIDI controller. Yet, having read the help files on Presets and Metasurface I cannot seem to find any solution. It seems like a huge weakness in the software if I can't simply assign an on/off MIDI controller (a pedal or drumpad, for example) to trigger presets, right? The only other solution I can think of is using other software that is better at this type of triggering like MaxMSP. I haven't even investigated the possibilities of creating an audiomulch object for Max, but I might have to. Any help to this newbie would be greatly appreciated. Thanks.
