Very interesting.

I wonder if there's any way to control the phases of the counters or if they simply run continuously.

If a pair of volume counters can be made to run 180 degrees out of phase with one another, then samples can be made to interleave and samples with frequencies above 14KHz could be produced.

Perhaps turning a channel on and off also starts and stops the channel's respective counter.

Maybe Toni knows.
