Separating midi tracks

[Tim Cappello]

I've got my snare and kick in midi on one track and I want to separate the snare pitches from the Kick.

How do I separate the pitches onto 2 separate tracks, kick on one track and snare on another.

I know it's easy cause I've done it before but forgot

Thanks

You can select all kick notes in PRV by clicking on the appropriate piano key, then SHIFT + drag to the empty space the selected clip in the track view. A new MIDI track gets created with the selected kick notes. I needed a more advanced version of the same where a Superior Drummer MIDI track gets split into several MIDI tracks according to the instrument, so i.e. all different hi-hat notes end up on a separate track etc. Asked ChatGPT to write a CAL script and after a few attempts got a working script that does all this automatically.

Acquire the note letter and octave of the drum hit you want to move, then you can do the following:

· Select the entire track that contains the drum hits you want to move.
· Use Menu > Edit >   Select > By Filter to restrict the selection to just the drum hit you want to move.
· Move NOW to the start of the first selected note. I have created a key binding that does this.
· Cut.
· Make the destination MIDI track active.
· Paste.

The way I've been doing it for years is to duplicate the MIDI track a couple more times than I need. So if all I have are kick and snare drum notes then I would duplicate the track 3 times. Then I rename the tracks to the instrument I want on it, then on each track I delete all the notes that I don't want there. On the kick track I delete all the snare notes and on the snare track I delete all the kick notes. I delete all the notes on the tracks I don't need at the time so I can add different drum instruments on them later and the tracks are already output to the synth I want. I label the unused tracks Perc 1, Perc 2, etc. and then label them for any new instrument I put on there. Is there a better and faster way to do it? Probably, but this way works for me.

Copy and delete as Chaps suggested is one way. You can easily select all notes of a specific note number(s) to be deleted by clicking/dragging in the keyboard/note names pane at the left of the Piano Roll View. You can also do a partial selection of the MIDI clip by this method, and then Shift-drag from the source clip to a new MIDI/Instrument track in the track view. Shift ensures the timing is constrained.

If you want to process audio separately, a separate audio track can be added as well which points to a drum vst.

For instance, you might want to add some reverb on the snare but not on the kick.  You might want to eq the kick and snare differently, etc.

I used to use a CAL script for this - best to read through the code and edit as required... it looks like you need to pre-create the 6 destination tracks first.

This for me has to be the way forward.

When I want to edit the Midi, it makes total sense to edit a given event in context with all the others.

For this reason I keep all my midi drum hits on the same Midi track

Same here...
