Devices

MultitrackStudio Professional supports up to two Audio channels, one MIDI In device and up to two MIDI Out devices.
MultitrackStudio Pro Plus supports up to 64 Audio channels (using the AsioSnd driverset), up to four MIDI In devices and up to four MIDI Out devices.

A 'driverset' is used to make your Audio and MIDI devices available for use by MultitrackStudio. This driverset can be selected in the Studio->Devices window, currently the WinSound and AsioSnd driversets are available. On Windows Vista there's also the VistaSound driverset. Clicking the Settings button will show the driverset's Settings window.

The Audio Input Control and Audio Output Control (available from the Recording and the Studio menu respectively) can be used to set the properties (levels, input selection etc.) of the audio devices. The controls depend on the driverset and devices used.

The MIDI Output Control (available from the Studio menu) controls the behavior of the MIDI Out Ports.
