Doepfer

hello ingo,
yes,i have AS vca's.i remember that they sounded fine
to me,but to tell you the truth, i haven't test them
recently in comparison to my new version a131's.maybe
when i finish the track i'm writing at the moment,and
manage to get out of this huge patchcable mess, i will
make some tests with the AS vca's.
bakis.
