When Playbeat 3 is loaded into an AUv3 host like AUM, the midi output settings only allow to select an existing midi device. When selecting AUM, this results in the midi beeing received in the „AUM Destionation“ .
All other AUv3 midi generator is own (and i have about 50 of these) use the midi connection supplied by the host. Only this would allow to use several instances of Playbeat 3 connected to various output instruments.
( See my list of midi generators at the Audiobus Forums Wiki )
Using the „AUM Destiantion“ is very, very uncommon - it‘s only Audiomoderns apps that do it that way.
Other apps work the following way:
- When started stand-alone, a list of devices is presented
- When started as IAA from a host, the IAA to host midi connection is used. One still can change the output channel, but there is no device selection.
- When started as AUv3, the AUv3 midi host connection is used. One can still change the output channels, but there is no device selection
The output channel of each drum-track can the be used in the host to split one Playbeat 3 output onto several output instruments.
