of these Roland-Edirol synth units that are supported. Does anyone
have any experience with these? I'm having trouble figuring out
exactly how they function. Do they receive MIDI data and then send
audio streams to the computer through USB?
Most of them have external audio outputs but do not allow to record
the audio over USB. The exception are devices like the SCD-70, which
can also record from its external audio inputs.
Do they receive MIDI data from the computer or from
another external
device?
They all can send and/or receive MIDI over USB. The number of external
MIDI outputs/inputs varies.
Are they well supported?
Yes; I wrote the USB MIDI driver for my SC-8820.
The parameter control software usually does not run in Linux, i.e.,
you have to construct SysEx commands manually.
