Thanks for helping me out with this. I guess I am trying to get my head around how using the plug-in as an instrument insert with a channel routed to the the side chain is any different than just having the plug-in effect in the insert slot of the bus or in the channel strip for that matter.
When I think of side chaining, I think of something being a trigger for the effect to process and release signal. So this is what I am thinking as an example..
If I insert a TBK1 MIDI filter as an instrument and route audio into the side chain, i am thinking that when I input MIDI notes into the instrument track, the filter should let out signal like a gate and mute the signal output.
I would vision the same result with say an ohm force delay where it only lets out the signal only when midi notes are present.
So I think I know what you may come back and tell me.. Why not use a gate.. True that I could do that, (and will to keep the project going in the meantime).
I guess where I am at is really trying to understand what purpose the side chain input has on an effect in an instrument channel with audio routed to it, if it sounds no different when MIDI notes are present from when they are not.
Given my intention above I would just put in as an insert the effect on a bus with a gate and skip the whole side chain on the effect and side chain into the gate. I guess I fell that is just giving up without understanding the manufacturers intent on how it should work.. Or I have a broken something somewhere.
Really what to hear your take on this.
