General audio and MIDI handling
Reason Rack Plugin doesn't communicate directly with your audio or MIDI hardware. Instead, this is handled by your
DAW host, which in turn passes on MIDI or audio to Reason Rack Plugin and gets audio back in return.
A Reason Rack Plugin instance can:
Receive MIDI notes and other messages from the DAW host. It does not care about MIDI channels.
Receive up to four audio channels (two stereo input pairs).
Typically, Reason Rack Plugin receives audio when used as an audio effect, but it's also possible to send audio to
an instrument (if your DAW permits this), for sidechaining and other effects.
Send out up to 32 audio channels (16 stereo pairs) to the DAW host.
In most cases, the output will be a single stereo signal, but you may for example want to route different drum
sounds to different outputs for processing on separate channels in your DAW host's mixer.
Reason Rack Plugin can also send MIDI to other tracks in your DAW - if you use the MIDI Out Device, see “MIDI
Out Device”.
