motormix.out The motormix.out object takes non-channelized data from your Max patch and adds an appropriate channel number. The motormix.out object takes non-channelized data from your Max patch and adds an appropriate channel number. For example, if you send the message "fader " into the first inlet, the result will be "fader 0 " (since channel 0 is the first valid motormix channel). Messages that don't need to be channelized (like the bank and group messages) can be sent any input, and will be output without change.
