Hello Dave,

As Lawrie was saying, MME is the best option as long as you are having no trouble with latency. MME is usually more reliable, and far less likely to cause crashes.

However, if you do want to use ASIO, this information should help:

- selecting "Microsoft GS Wavetable", "MIDI Mapper", or "No MIDI" will all produce the same results. This is because they all send MIDI to the GS Wavetable ("No MIDI" sends MIDI to the default MIDI driver in Windows which is the GS Wavetable).

- the ASIO4ALL driver, and probably others, conflict with the GS Wavetable (this is what causes the "...in use by another application..." error)

- so, because of this, you need a neutral driver. You can download the Loopbe1 driver for free from this page (last link on the page):

- you won't actually be using the driver, but simply having it selected for output (don't select it for input) should stop the error messages
