Selecting VST3 instance multiple outputs

[boonier]

Hi there

I just tried a VST3 version of Bidule (macOS) and it only has 2 outputs for the effect/instrument, and whilst I didn’t expect that for the effect version (as Renoise has some limits there on routing between different tracks), I was expecting to be able to select different output configurations for routing from the instrument.

I know that this is a dynamic runtime feature of VST3 - to be able to change the configuration once it’s instantiated. How do Windows users handle this, or multiple outputs from VST3?

Cheers

You mean like this?

YEah exactly - but some VST3s [can] define their inputs/outputs at compile time which gives Renoise something to map to. But Bidule doesn’t it seems, hence why only 2 outputs. Though in REAPER for eg. the number of busses can be chosen at runtime, and the plugin routing updates accordingly.

I’ve have a dig to see if maybe there is a config one can set in Bidule VST3.

I guess this is more an exercise as I was using AU (which presents all the outputs) but there seems to be a UI bug between Renoise and Bidule, that crashes Renoise.. (that’s a separate bug)

VST2 seems to be the most stable and reliable between the 3 though.

There is a solution; for anyone using the Bidule VST3:

Open Terminal, and enter the one liner below:

defaults write com.plogue.bidule VST3Hosts.Renoise.overrideDefaultBusCount -string "2;16"

Will give you 2 stereo input busses (inc. sidechain bus) and 16 stereo output buses. You can add more or less output busses with for e.g. “2;32” or “2;8”. I’ve not tried adding more than 2 input busses though…

Confirm the preference is set by entering:

defaults read com.plogue.bidule VST3Hosts.Renoise.overrideDefaultBusCount

(on macOS the prefs file is located in ~/Library/Preferences/com.plogue.bidule.plist, I’m not sure about how this is best done on Windows sorry)

In what file did you change that?

I updated the solution; thanks for the nudge
