Help with General Midi USB interfaces on OS 9 (M Audio)

[Skate323k137]

Hello all,

I have 2 of these interfaces:

I'm trying to get them working on OS 9.2.2. Using the Quattro drivers found on Macintosh Repository, I'm able to get sound out of the cards when connected to my Pismo. But try as I might with OMS I cannot get working midi output (My sound canvas doesn't seem to be getting any incoming notes at all).

I can select the Quattro in OMS, but I also know I can select general midi as a synth for quicktime. Do these conflict? And has anyone here gotten MIDI working out of one of these cards on classic MacOS?

I was able to get this working, with the help of it's manual, as well as some help from the Roland UM-2 manual with OMS in general.

I've got it outputting to an SC-55 at the moment, just with MIDI files, but ideally I want to re-play some old games I grew up with, using the Sound Canvas I did not have back then
