Question

There's a flaw when bouncing midi to audio.  The bouncing is done by muting the tracks and processing them individually.  However this doesn't work when you split notes to track and theyre using a choke.  While in its midi form the choke groups work but if you bounce them the choking is ignored.

How To Replicate:

1) Load up Impact load up a preset Jazz Kit 2 i.e.

2) Make a hat pattern using closed and open hats.

3) Explode pitches to tracks

4) Bounce the open hat track and notice the tail

Answer 1

Interesting catch. This behavior occurs when bouncing any multiple Instrument tracks that are routed to the same Instrument, such as interactive passages on a monophonic instrument. It also applies to when you Transform multiple instrument tracks that reference the same instrument. It even happens with overlapping events on the same Instrument track when Play Overlaps is enabled.

If you want to keep the notes on separate tracks the way around this is to use Mixdown Selection on the set of tracks. It also might be good to keep your choke groups in their own folders so it's easier to remember when to Mixdown vs Bounce.

I think the current easiest way Studio One is setup for all this is to keep monophonic material such as choked hihats, choked sample chops, and monophonic Instruments on their own Instrument Part so they get bounced/rendered "in context". The way Transform works seems to be tailored to that, especially since you can render the outputs of things like Impact separately. So Closed and Open Hihats could be on separate channels.

The more I think about it, this might be for the best. Even though I totally get where you're coming from for monophonic drum parts and sample chops, changing Bouncing to accommodate that would really change up how other instrument parts are bounced, such as monophonic leads or polyphonic instruments with small extra notes on other tracks. It could get a bit dicey if it wasn't implemented properly. Just my two cents.
