Sorry if I hijack your topic but in theory you can have this mutltiple-something send device for a lot of FX.
To make this more modular (and this reusable), I think it is time to have the dsp chains in a graph format.
For the mutiple band-filter send device, typically the graph will look like:
The split-device will simply replace the send device. The add(er) device will be decided how much percentage (weight) of each input is mixed to the output. Mutliple inputs can be created on the adder device.
Now you only need to route tracks to the signal input of the graph.
It is the simplest but it is also the less modular. Also the team have to make some assumptions about the hardcoded filer settings (MAybe you want to split on HP and LP, Q-factor?).
A native multiband compressor would be and probably also sound great! Especially if it could do upward compression. I use the apple multiband but its not cross-platform etc so shared songs wouldn’t work.
multiband compression is easy enough to set up in the instrument fx section using multiple fx chains and sends, if you’re using native renoise instruments & not vsti
I just wish we could have internal multi chain routing within doofers, so that this could all be saved within a doofer and dropped wherever you want it. Internal doofer dsp chain routing would be huuuuge & game changing for renoise, especially if we could get modulation in and out of it intelligently
