OK, I got it!
CCRider must be inserted on a MIDI track. As it is considered to be an audio plugin, the track's outputs will show only Audio destinations, and it won't be possible to insert MIDI devices or instruments after it.
The second step is to create a new MIDI track, and set its input to the track CCRider is on, as "Post FX". This will read the MIDI coming from that track,
after CCRider. All that's needed after that is to set the 2nd track's MIDI output to the Scope MIDI port.
From this point on, any automation drawn in the timeline for CCRider on the 1st track will be sent to the 2nd track, where it can be recorded into a clip, or simply routed to the desired MIDI port.
So, for example, I have a Minimax set to Channel 1, on MIDI port 8. Cutoff Frequency is set to CC15. I would first insert an External Instrument device, and direct it to that port and channel. After that, I'd insert the CCRider plug-in, and draw some automation on the timeline for CCRider, CC15. Playing the track will play the notes, but no changes to the CCs can be heard. So, I create a 2nd MIDI track, set it's input to the Minimax track, post FX, input monitoring on, and route it to the same channel and port as the other one (Ch.1, port 8 ). Now, the automation curves will affect the frequency cutoff on the Minimax!
The big advantage is that you can draw and set the CC parameters for Scope devices (or any external MIDI devices) on the timeline, and on the very same track as the notes, without having to create additional clips, or worrying about erasing automation when replacing clips, or re-recording notes. The downside, is that it still takes 2 tracks for each MIDI channel, one for notes, another to route the CCRider data, although one can bring the empty "router" tracks to the bottom of the project and out of the way.
Pretty cool!
Thanks again, Voidar!
P.S. BTW, I was trying out Usine, and it looks pretty powerful... Will take some time to learn the basics, but it does seem pretty interesting indeed. I was trying to build an LFO device, and I *almost did it* - i managed to create an LFO ranging from 0-127, that cyclically changes the 2nd value of a set MIDI CC generator. When I pressed a "create" button on the generator, it would actually output a CC value to a Live track, but I would have to press it each time I wanted it to generate the message
Fun, but not what I intended... I'll dig deeper though. Quite happy with CCRider now!
