I have just got an Organelle, and I was trying to use it with MIDI keyboard synths, but with no success.
The other synths are Novation Bass Station 2 and DSI Pro 2.
Both synths are on channel 1, and each can play the other through USB and MIDI OX on Windows 10.
Each of the other synths was connected to the Organelle, one at a time.
It appeared in Settings->Info->MIDI Dev, but did not respond to notes played on the Organelle, and the Organelle did not respond to notes played on the other synth.
Here are some entries from Settings->Info
MIDI Dev: Pro
Patch: Additive Synth
Here are some entries from Settings->MIDI Setup
MIDI In : Enabled
MIDI In Ch.: Omni
MIDI Out : Enabled
MIDI Out Ch.: 1
Any help appreciated.
