[sdiy] Hello and Groove M2CV

[dave]

Hello my name is Dave (nicknamed Chaddy to my friends or anybody for
that matter).
I subscibed to the list a few months ago and have been receiving some
excellent stuff. Looking at the banter that goes on, i have visited
sites i would never have found by myself, i thank you all for that.
In fact i have done so much surfing that i have'nt had time to ask any
questions on here.
I've been a fan of Synths since the age of 11 (1972) when someone gave
me Pictures of an Exhibition by ELP to listen to. I was dumb struck by
the sound. 
I now own a Digisound Mod80 Bought as a box of bits in the early 90's
for £50. Can be seen on my web site www.chaddy.co.uk


My question is this.  Has anyone got any useful info on the Groove
Electronics M2CV midi - cv unit ?
The one i have drifts slighlty of tune everytime i switch it on.
Is it possible to make it stable?
Has anyone done any mods to these?

I thank you for listening to me ramble on.
Look forwards to comments.
Dave.    (or Chaddy).
