Here’s some maps and guides for using the Morph with some different inexpensive synths. That link takes you to Google Drive where you can see all the files.
I went through all the MIDI specs and picked out some expressive controls for all these devices and mapped them to the Music Production, Buchla Thunder, Drum Pads, and Piano. As a result, there’s a lot of really expressive play in these that you simply can’t get without the Morph.
We use this “tower” in our in-person demos - here’s a quick video example on YouTube.
This zip has all the maps, guides, and a photo.
