I remember talking about how === could be used to halt a DPCM without the implicit Z00 of ---. In the 0.3.7 I assumed it was working but never bothered to check until recently; now === seems to do nothing. Was that intended? (Exported NSF behaves the same way.)
You might be right about that, I don't know why it stopped working actually.
I'd rather remove the Z00 effect from the halt command (now when that is possible to do manually), but changing stuff usually means trouble for people. Initially I thought about using the release command to release looped samples.
