Bought a Roland UM-One from list of tested devices that work. Hooked it up per video. Device = UM-One for input, controller and output. Channel = one for input, controller and output. KPA MIDI set to channel one. Get proper lights on UM-One. The Kemper goes silent when starting ToastME. The ToastME program communicates properly with KPA as the editor seems to function properly (Kenper responds to editor changes).
No sound from Kemper. Shut down ToastME. Still no sound from Kemper. Reboot Kemper. Kemper seems to work properly (sound is working). Restart ToastME. Kemper goes silent. Very repeatable.
Start KPA -- start Toast ME --kills sound
Start ToastME -- start KPA -- everything works
Start KPA (MIDI cables disconnected) - Start ToastME -- connect MIDI cables - everything works
Start KPA (USB disconnected) - Start ToastME - connect USB - UM-One does not connect to KPA
Seems like there is something in the ToastME initialization that is corrupting the KPA.
Verified Output settings do not change when sound is lost.
Tried "Init Globals" after sound is lost to ToastME start-up. Does not restore sound.
Only KPA restart seems to restore sound.
Do not have to "connect" (soft button in program) ToastME to lose sound. Just start program.
