Audio output will by default go from your master to the first available pair of outputs on your soundcard (usually outputs 1 and 2), and only to this pair. If your sound card has multiple pairs of outputs and you wish to change this, you can do so via the Routing Matrix (View, Routing Matrix or Alt R). MIDI Output can be directed to an external hardware or virtual synth (such as Microsoft GS Wavetable) or to a VSTi Instrument plug-in. For the former. Open the track’s routing window and select the required synth from the MIDI Hardware Output drop down list. Alternately, to use an instrument plug-in, insert the required VSTi in the track’s FX chain. This will usually be the first item in the chain.
