I am back having re-bought RC after seeing the offering of an AU MidiFX plugin.

Have to say that version 4 is everything I hoped it would be, the interface is fantastic, and the AU Midi plugin is the icing on the cake. Great job Attila!

So I'm wondering when using RC as a MidiFX plugin, would the maximum number of instances be limited to 16 channels of midi?

I haven't done much testing yet, just trying to learn the interface and am about to build a few templates so was wondering the best way to go about it.

I guess I have a follow up question. Is there a guide on how to use Rapid Composer in Logic with the new AU MidiFX plugin? I remember crazy workarounds that didn't really work well by wrapping it in other plugins. I can't seem to understand how to output multiple channels/parts to different tracks.

Thanks for any help!

Hi InLight-Tone!

Yes, I am afraid the maximum MIDI channels for AU is 16 at the moment.

Recently I managed to increase the VST3 channel count to 128, which is supported by several DAWs. For AU there are some non-standard tricks to increase the channel count (very complicated, using a dedicated MIDI CC and scripting, I think), but I have not spent time with it yet.

I hope someone will correct me if I am wrong, but I think an AU MIDI FX plug-in is not able to output more than one channel (maybe through IAC MIDI ports?). The track will receive the MIDI directly from the plug-in.
I recommend using the RC AU plug-in which routes MIDI messages to a virtual MIDI output port called "RapidComposer Out". You can receive MIDI messages from this port in your instrument tracks. MIDI routing is unnecessarily complicated when using AU.

Thanks,
Attila

Thanks for the reply Attila. Since this is Logic specific I will need to do a lot of testing to see what works and what doesn't. I was under the assumption that I could load multiple instances of RC as an AU MidiFX plugin, and they would all communicate with each other, so one is the master and the rest follow.

Scaler as a MidiFX works that way, you have to press an update button and it sends it's state to the other instances. Also Orb Producer seems to work that way as well, the Chord plugin sends it;s state to all the others.

Anywho, lot's to explore, I'll be back when I figure some things out!
