What you optionally do for free with blitter is :
- decimate bits with half pattern mask
- shift bit (reduce volume)
- octave transpose

Instead of generating sounds, this new prototype use samples which allows easier experimentations (no need to code) SYNTH.INI script allows to change parameters

I have made some experiments with PCM sound. My initial idea was to try to find some unexplored ways to produce sounds on STe. In particular I have tried to look if there was something to do with blitter which is not really used for this purpose currently.

What I found useful using the blitter for sound: On the other side, I did not find a way to use it to : These facts led me to make a sound routine : The routine is divided into two main parts : Next steps :
