Great release, thank you! Should have a look a Quigs 
And interested in the BF Compiler!
Currently I'm beta testing new things which Prodatron is currently developing for the next SymbOS release 
like playing MOD files playing on OPL4!
Yesterday Prodatron released SymAmp 4.0 for SymbOS, adding cool features, like more music in your play list and support for OPL4 Moonsound MOD playback!
Many thanks to Maarten Loor/NOP for the Amiga MOD player routines! I am sorry that it took 2 years since your adaption for SymAmp, but now it's really working fine!
Another old dream came true, and now I can even play MODs on my Amstrad as well, using an MSX MoonSound catridge. Beside the G9K and the MP3MSX it's now the third MSX hardware, which is working on the CPC in a great way (and on the Enterprise 64/128 as well!).

It is very cool Prodatron!
Congrats, I was wondering if you used that code (which has been updated btw).
Yes, I am using your code with much pleasure I only had to do some little fixes and some more adaptions. The only real issue, which took me some time to find, was a negative label assignment (something like "LD HL,-LABEL"), which the code relocator didn't like at all in case of SymbOS 
I think the updated code mainly contains the implementation of the panning (8) and sample offset (9) commands? I will add them later, I think especially the second one is important for some MODs.
