Subject: Hardware synchronous port control of DACs
From: "Grant Richter" <grichter@...>

The residual latency in the CV update times of 2 milliseconds is almost entirely based on the
serial bit transmission time to the DACs. The software serial support currently in place has a
limited top end speed.
In theory, switching the DACs to the hardware synchronous port could increase their update
rate by a factor of 10 or so.
That would increase through put from 500 Hz to 5000 Hz, then audio processing becomes a
possibility.
I will try to get to it sometime this summer. Maybe someone else has more time now.
