AsioSnd

Note: this driverset is available for Windows only.

This driverset makes ASIO audio and Windows MIDI devices available for use by MultitrackStudio.

ASIO drivers allow for low latencies and avoid track synchronization issues. In addition AsioSnd allows multichannel recording (Pro Plus edition only). If a sound device comes with an ASIO driver then it's usually best to use the AsioSnd driverset.

AsioSnd Properties window (Pro Plus edition. Professional has only one MIDI In and two MIDI Out devices)

In the Audio Device section you can select the audio device that will be used.
On clicking the Control Panel button the driver's control panel will appear. This panel usually lets you set the buffer size. Buffers can be up to 4096 samples (this corresponds to 93 ms at 44.1/88.2 kHz and 85 ms at 48/96 kHz). A buffer size of 256 (at 44.1 kHz) can be considered a good compromise between reliability and low latency.
If the buffers are too small glitches will occur. This may not be a problem when playing back audio or recording MIDI, as the driver will usually stay in sync so any glitches will not appear in the final master. It's strongly recommended to use large enough buffers when recording audio, as glitches in the recorded track do appear in the master.

In the MIDI In Devices section you can select the device that is used for MIDI recording.

In the MIDI Out Devices section you can select the device that is used for MIDI playback. The 'Default' option uses the default Windows MIDI output device.

If you have a hardware control surface you can select the MIDI devices it is connected to in the Control Surface section.

Audio Input/Output Control

Audio Output Control using AsioSnd The Audio Input Control and Audio Output Control (available from the Recording Options section and the Studio menu respectively) determine which in/outputs will be used. The listed in/outputs will be used from top to bottom. They can be reordered by dragging and dropping them. The Automatically assign channels to tracks button (Audio Input Control only) can be switched off to let you assign channels to tracks manually.
