Hi Richard,
My plan to split things that way probably demonstrates my lack of understanding: I suspected that the wavetable would need to be updated to move the stereo position, since I couldn't see how to tease out the two elements. If one can simply rewrite that small block, that's obviously an easier and quicker solution, and is fine with me.
Best wishes,
D

They're entirely independent. The stereo mix (pan position) is simply a function of the relative left and right amplitudes whereas the wave table determines the quality of the sound (e.g. what harmonics are present).

I conclude that there is insufficient interest to warrant any further effort.

To avoid any misunderstanding can I clarify that I already have fully-developed and tested versions of the HQSOUND library which support returning pointers to the stereo mix and wave tables.

Which version of BB4W was this intended for? AS I understand somethings changed in V6?

Sounds very nice. (Not that I can understand the code).
Were there long term plans to add more channels like on RISC OS based systems. ( which also have per channel wavetables)? I won't be disappointed if this isn't planned.
I will also note that somewhere in the BB4W notes is some assembler code for calling sound from assembler... Now if someone can figure out how to tweak that code so it can add it into the BB4WFORTH you wrote a while ago (Aside: Not sure if this needs patching for BB4W6.0a) then with BB4WFORTH+HQSOUND means a Windows based AMPLE is a lot more plausible again. Any takers?
IIRC the original Music 500 used 7bit samples, Hmmm....
