I got a first version of the software converting part of the Seaboard to a Ribbon controller working !
You can choose a range of keys and while all other touches on the Seaboard are processed normally (this plugin reduces the channel count of the MPE stream to a single channel, anyway, and calculates appropriate channel control values from the multiple control values than come in via MPE, or all pressed keys), the messages in that key range are handled especially:
- The exact position of the press in that range is converted to a new CC #, to be used as "expression" in "Bowing" mode of a SWAM solo string instrument.
- the pressure in that range is converted to yet another new CC #, to be used as bow pressure.
ToDo (but verified to be possible):
- detect the vertical position of the touch to determine if you want to use the "Ribbon" or the keys (e.g. to use them for the SWAM keyswitches)
- send a small part of the vertical position as yet another new CC #, to be used as bow position.
If anybody is interested to test this, please let me know.
