I'll try to explain my problem another way :

Suppose you want to play thru a 3 octave range with the simple
theremin (A178 CV out to the A110 CV2 input). You'll need to move 8"
(20 cm) to play notes in the lower octave (C3 to C4), 4" (10 cm) to
play notes in the middle octave (C4 to C5) and 2" (5 cm) for the
highest octave (C5 to C6).

I wish I could play in this 3 octave range with equals spatial moves
(example : 5"=12,5 cm an octave).

I don't think a VCA would fix my problem : A131 would make it worst
(exp x 2) and A130 won't change anything (exp + lin = exp).

Perhaps The A111 linear FM input would do it, but I'd like to read a
user feedback/review, before buying it.

Best,

Pierre

PS : ravi de te rencontrer Alexandre. J'habite près de Paris et j'ai
lancé un post identique sur Audiofanzine. Alors à très bientôt.
