Roland U-20 / U-220

Multi Patch Editor

This patch editor ought to work properly with both the U-20 and the U-220. However it has only been tested with the U-220. Please let me know of any discrepancies you discover.

Communicating with Edisyn

Set Edisyn's MIDI channel to the same as the RX Control Channel (typically 16). Set Edisyn's Synth ID to the same as the Roland Device ID (typically 17). Set the unit's Part Change to "On" or "Dir". On the U-220, set the Timbre Change, Rhythm Change, and Rhythm Ins. Assign all to "Dir". Turn on Sysex receive.

About the Menu

Edisyn's MIDI channel is set to the RX Control Channel so Edisyn can change multimode patches. To play a sound in a given part, you'll need Edisyn to send note data out the appropriate Part channel. To do this, just use the menu to set the Part you'd like Edisyn to play, and it will use the Receive Channel of that Part as you have set it in Edisyn. If you use the menu to set the channel to the "default" channel, it'll use Edisyn's default MIDI output instead.
