Following up on the recent Ableton Live set, here’s a simple analyzer-modulator project for Reaper. The routing of signals is simpler and more flexible in Reaper, so we do not have the clutter of an extra channel to
enable MIDI out, rather we can select MIDI hardware output in the routing dialog for the MIDIator track. In Reaper, the MIDIator plugin will start processing all by itself (no need to open its editing window to kick it to life). You need to enable a virtual MIDI device for input (remember to also enable input for control messages) and output. This is done in Reaper preferences / Midi hardware setttings.
The analyzer does not send audio throu, so we still need to use two input tracks; one for the analyzer and one for the actual audio input for processing. The MIDIator is set up to map the spectral flux of Analyzer channel 1 to Midi controller 11, channel 1. The audio input is sent to a Reverb channel, and we’ve mapped the MIDI controller (11 on channel 1) to the Room size control of the reverb.
