Xfer’s LFOtool seems to be some kind of standard among producers when it comes to automatically modulating automation in DAW:s. By the looks of it, it seems pretty archaic in comparison to the Renoise meta devices.
Maybe it could be made possible to use the meta device system in Redux to output CC with an additional CC output device? I could see this becoming a better standard for MIDI modulation in the numerous DAWs that lack this kind of feature, which seem to be many of the big ones. And why not add an audio input device for sidechain support to Redux as well, making the signal follower useful in this scenario
