- The audio.device noteplayer was removed some time ago. To quote DeliTracker's
- manual:
-
- AudioDev-NotePlayer --- Removed ---
- We removed this noteplayer because there
- are bugs in the audio.device which cause
- many problems. There are no workarounds
- for these bugs.
-
- I presume one of "these bugs" was the timing problem you refer to. All of
- DeliTracker's other players allocate the channels via audio.device, before
- setting off to hit Paula directly.
-
- Does audio.device only have these problems when playing back the same sample
- on two channels? If not, and the problem is always present, audio.device
- would be completely unusable for more tricky stuff like the "emulated" 14 bit
- players now doing the rounds - get the two portions of a 14 bit sample
- out of phase between the two 8 bit channels and you will get rather nasty
- distortion.
