Hi Stu

I have some addon features for this:
> 8/16 (maybe also 24?) bit sampling

> gate (not trigger) for play/record
replace this by:
gate(+switch) for run/stop
gate(+switch) to select between single shot / loop mode
gate(+switch) to switch from gated mode to so called "release-mode" (if 
in single shot, the sample should be played to the end; if in loop mode, 
the loop should be played endlessly until the next start/retrigger is 
given).
trigger(+momentary-switch) for restart
trigger(+momentary-switch) for start
trigger(+momentary-switch) for stop (use case: two samples eliminate 
each other, like hihat/openhat).

> gate to select play or record
This record setting should be an pre-enable setting; the real write 
setting should be done by the start signal.

> cv input for sample rate
> cv input to scan through sample
cv inputs for start point / stop point / perhaps also loop start 
(similar to the editing the Akai S612)

The module should be mono, but there should be the possibility to link 
several modules by the clock and the address bus, so it would become 
stereo or even multi-channel. The write/play selector should stay 
independent on each.


There should be either two (switchable) inputs and outputs: one 
AC-coupled for Audio, one DC-coupled with suppression of negative 
signals for recording CV and/or gate.
Or the module should be produced basically as the identical module but 
in two versions. One ac-coupled for Audio, one for dc-coupled for CV/gate.

The dc-coupled version might have additional three 
trigger-in/momentary-switches for
- count RAM-address one step forward
- count RAM-address one step backward
- write input value to actual step.
This would be similar to the programming of the roland CSQ-600.
