So with very few tracks playing - in fact, with just one playing - everything is good for maybe thirty seconds to a minute, and then the playback starts to distort, little by little, until it’s just grey noise.
As you can see in the linked video, the Audio Performance Monitor shows no problems, and neither is there any serious consumption of CPU or memory on my PC. The audio device I’m using is an Alesis IO2 Express, and the driver is ASIO4ALL (latest version).
In fact in the video, I’m not even playing back the multitrack. I’m just keying an audio loop. At the point the video starts, the loop has been playing for about thirty seconds.
Any ideas? Thank you for your attention…
