Ribs is available as VST and .exe for PC, and AU, VST and .app for OS.
Put Ribs on a track and turn FX mode on ( on the top left of the UI)
Add or route some audio to the track
Push play in the DAW
Press Ribs’ tab tops – the buffers will start filling with the track’s output and a sound will appear
Currently Ribs does not support loading .wav files and saving buffer contents.
NB1: For hosts with routing range restrictions (e.g. Ableton Live) right-click the multiinput button – channel config – select stereo channels 2-4 and you should be fine. See this video as an example: https://www.youtube.com/watch?v=l4GbuW9H_v4
NB2: For hosts that don’t allow audio and MIDI routing to the same track (e.g. Cubase) Ribs will work properly in FX mode only.
