i saw some kits to supley the theremin with cv -out ,
wonder:
1 are those kits available still also from moog?
2 is it also usable to upgrade the theremin signature, or are those versions to old?
i’m asking this as i want to buy an theremin and can buy an signature one, although i want to be sure i can upgrade her to cooperate with my voyager
thanks beforehand
Any Moog theremin should be able to accept the Plus Upgrade, which should still be available…at least according to moogmusic.com it is. 
Sunny…did you check the following link…seems that they also sell the upgrade : http://www.theremin.nl/winkel.html
yes, just contacted them, thanks
thanks, did buy the serial 111 signature from grooveron and also the upgradekid from the adress above.
still have to build it in and practice a lot.
keep you informed when small results occur
Tx for the update Sunny…have a Thereminy X-Mas…
