  1. Channel mixdown: Simple average doesn't seem right?

    Hi Everybody.

    I'm tackling polyphonic synthesis, and have created eight 'wavetable' channels, each with short buffers, volume, pitch, and pan settings. This all works, except the way I'm mixing...

    It would be nice to combine stuff into an efficient, clean,...

  6. Ported a driver for a 7.84" 1280x400 bar-style IPS display

    Hi Everybody.

    I've been playing with this display, and it is very nice. They run down to 3.3V,
