Your summary is spot on.

Just tried another song - render works fine. Tried playing it back with VST/DXI synth (Coyote) turned off to check it was not playing MIDI drums - I use SD-50 (which is playing MIDI and Audio) and it shows no MIDI drums playing. Also listened to WAV file in Media Player - drums are there and sound like Real Drums.

Play - stays yellow.
Gen/Play - stays yellow. These two I wouldn't expect to make a difference as all tracks are frozen and song rendered so they don't really do anything except kick it into life.

Tried same thing with all tracks muted except drums - same thing.

If I unrender the song, the drums go back green again but don't play at all. I have to reload the song (e.g. previous / next) to get them back again, or unfreeze the drum track and regenerate it.

Happens with every song.

Also tried it with one of your demos - realtrack40 demos - _ROKAARP demo. Same thing - goes yellow on render, comes back green on unrender and in this case plays drums again as track wasn't previously frozen.

Shout if you need more info.

Thanks
