MIDI controlled FX plugin in Garageband?

[cc_]

Has anyone managed to make a MIDI controlled audio FX plugin that works in Garageband with IPlug? I have a plugin that will load in an FX slot, but I can't figure out how to route MIDI to it so maybe I did something wrong?

I have an IPlug instrument that receives MIDI. However, because it is an instrument I guess MIDI automagically gets routed to it.

I have an Instrument version too, it gets MIDI, but there doesn't seem to be any way to route audio through it. I need the MIDI to turn the audio on and off.

I forgot to mention that I have implemented oli's mod to IPlugAU.r :


#if PLUG_IS_INST
kAudioUnitType_MusicDevice,
#elif PLUG_DOES_MIDI
kAudioUnitType_MusicEffect,
#else
kAudioUnitType_Effect,
#endif


So the FX version should be reporting type MusicEffect.

According to Apple's documentation that should be the right type indeed. I just checked with auval -a, but I don't seem to have any plug-in of that type, so I can't test if/how those kind of plug-ins work in GarageBand.

Thanks for looking, it seems to be a Garageband limitation. auval is reporting the right type and I have it working in Reaper and Live.
