Hi BobF ...

Wasn't sure what this might be ... after running it, I'm SURE I don't know what this is


Is there a simple explaination.

Hi Bob

Great idea (as always!)

I've Spogged it a bit! I hope that's ok.

The results on headphones are really interesting but I found the sound to be rough. On looking through your schematic I saw a lot of green stuff affecting the audio chain dynamically. I've found that anything in green is too slow and not timed too well for audio. I believe the compiler is focussed, quite understandably, on the audio processing and does the green stuff when it has a moment or two. Or something like that anyway.

All the time-critical stuff is now in Mono and I've taken some liberties with the LFO handling. The LFO produces a bipolar output and I thought it worked better generally with unipolar control.
Have a listen and let me know if the results are the same as you intended. If not I would be interested to know and modify it further.

Another point, and this may not apply to the FL Studio version, I needed to add the Stereo clipping module to the output. Without that I get very odd soundcard behaviour, like no sound or just one channel etc. I always add one of these and get no more problems and it may be that some others have the same issue. I do wonder if this is caused by 'invisible' spikes on the digital values going out but I just always add a clipper as my routine.

Anyways, thanks for another inspiring idea my friend.

Cheers

Spogg
