>Geoff, what specs do you need on this?
Because, if what you want to store is a "wiggling" CV signal and playback
later,
this can be done by using the CV to freq modulate a carrier, then store the

result as audio, and use usual audio techniques to delay/store before the
FM decode. Before digital, this was used in telemetry.
If you are happy with a CV cutoff of say 400Hz this wd be pretty
straightfoward.
I guess a full digital solution is better/cheaper now, but I'd like a FM
approach!

Hi Paul:

There is a better method that we currently use for laser light show
programming.  I own a business that does laser shows.
Nobody does the FM carrier on audio tape anymore, what we use is an Alesis
ADAT, modified by jumpering the capacitors in the input and output
circuits.  After doing this mod the ADAT will record down to DC with 16 bit
resolution,  a bandwidth fo 20 KHz, and 8 independent channels.
