Bouncing MIDI to audio - Feature request

Apeirofobia · August 29, 2019

Hi guys.

These last days I've been struggling with finding an easy way to bounce midi information into audio tracks.

I've been using a Drum VST (among others) that doesn't allow multiple outputs so this task has been very tedious for me.

I've tried the CAL method too, but it has displayed some errors while creating the tracks.

By now the easiest way I've found to achieve this is to paste as many VST tracks as drum parts the song has, and bounce them individually into audio.

It would be so cool to have a feature like the one shown in the video in Cakewalk, cause since I've moved into this DAW, the experience has been amazing and I'd love everyone to use this software.

The last DAW I used was Studio One and it has this easy way to bounce midi notes into audio.

Greetings and have a nice one!

When using Split Notes to Track CAL do not use instrument tracks and move the source track to the bottom of the project before running the script.

Keep in mind a drum map may be used to send note ranges to different synths. This may be used to break out different kit pieces to separate instances of a plug-in. Once created, save the MIDI and audio tracks as a track template.

I'll try with the CAL again, thanks for the advice!

But anyways, I'd love to see in Cakewalk an easy way to do this task just like in Studio One.

The thing is splitting individual notes whether MIDI or audio does not seem particularly useful except for the case where each note plays a different instrument.

In the case of drums synths most kit pieces have several notes mapped to them. It makes more sense to map all the notes for a kit piece to one track. This can be done by taking the CAL script provided by Cakewalk and modifying it to create tracks based on the drum synth kit layout rather than one track for each pitch.

As mentioned above, it is relatively easy to route all the notes that play different kit pieces to different synth instances.

Both of these seem preferable to having multiple audio tracks for a snare or hi-hat.

Maybe I'm misreading the OP, but to get individual MIDI drum parts (and overhead/room mics if the synth has them) rendered as independent audio tracks for each kit piece:

- Choose to create a separate MIDI track and 'All Audio Outputs - Mono' when inserting the synth.

- Freeze the synth, and each part will be rendered to its corresponding track.

- For stereo room mics, you can reset the input of one of the mono tracks to the appropriate stereo input, and delete the extra one.

- And you can save the whole setup as a Track Tmeplate, including a Drum Map on the MIDI track ouput(s) so you don;t have to go through the setup again.

I tried this method but some VST's dont allow multiple outputs, so when I choose "All audio outputs" I only get a few tracks(mono and stereo) that contain the full drum kit pattern.

Oops. missed this. Time to upgrade. The bundled Session Drummer has separate outs.

Similar to what Steve suggested, I would put put a drum map on the MIDI track, allowing you to solo each kit piece (or groups of relate pieces in the Drum Pane of the PRV before bouncing. Saves creating a bunch of different MIDI tracks, but still has to be done as individual bounces.

That seems one of the easiest ways to do this in Cakewalk. Thanks!

@Felipe Andrés Riquelme Gonzále - if you want to look at the CAL route, here's my old script for splitting up drum tracks.

Before running it, you need to create 6 new midi tracks (for bass drum, snare, toms, hats, cymbals & other percussion) - although you could alter the script to create these for you.

This is mapped to GM notes.
