[quotePost id=114759]I'm new to CUBASE, I started using it couple weeks ago when I got the AI Code with the MODX. I just noticed that I can't select a specific MIDI Input Chanel for a particular midi track, and the only work around is using "Tranceformer", which is not available in AI/Elements.

Say I have a multi parts performance (say 2 parts), each on different MIDI chanel. For example, keyboard is split in 2 and one hand is playing chords and the other a solo. How I can record the midi notes separately in Cubase AI on 2 different tracks, each recording each part separately?

I was using Cakewalk with the other keyboards before the MODX, and that was easy, I could simply select the midi input and its specific channel on each track.[/quotePost]Cubase AI is the light version of Cubase - Cubase Pro is the pro level version (with Input Transformer).

What to do in Cubase AI
Since any MIDI Track in Cubase AI records all incoming Channels, you need to use only a single Track.
If you are playing multiple MIDI Channels in the MODX, simultaneously, you would setup just one MIDI Track in Cubase AI
The Track can be set to record all incoming data - which is kept separate by Channel...
Set the MIDI IN - MODX-1 (Port 1)
Set the MIDI OUT - MODX-1 (Port 1)
Set the (Track's MIDI OUT) Channel = ANY
"ANY" allows the Track to OUTPUT the data on the Channel on which it arrives.

Once recorded, you can use the MIDI function "DISSOLVE PARTS" by Channel - which will split each MIDI Channel to its own Track. Separate MIDI Tracks are only necessary to make editing, soloing, notation, etc., etc. easier. The single Track records all data on the MIDI channels on which the data originates.

I've also used plugins that would filter on MIDI channel to do this. Then each MIDI track would get its own filter settings. Things have changed since those days. I think the developer for these dropped off and the original set was 32-bit. I wouldn't recommend that set today - but there may be something similar now days.

There may be no benefit in recording this way, though considering the option to dissolve.

Thanks all! The "Dissolve" function did exactly what I was looking for.
