Question on VST3 Bus Layout

[kamedin]

SIdechain input with synth plugin?

Although this is in theory possible with the new multi-bus API on the develop branch, many DAWs will not allow this configuration. For example, Logic will always present the first bus as the main input bus. There is no way to “skip” a bus with AUs. Same thing is true for VST2s. VST3s do support a flag to indicate that your main bus is a sidechain bus but JUCE doesn’t support this.
