AsioSound

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

AsioSound allows multichannel recording (Pro Plus edition only). In addition it generally allows lower latencies than DirectSound drivers, especially on Windows 2000/XP systems. If a soundcard comes with an ASIO driver then it's usually best to use the AsioSound driverset rather than WinSound.


AsioSound Settings 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 buffersize. 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).
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 option 'MIDI Mapper' 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
