hugo,
i saw a performance in the early `80`s at the smithsonian in washington, d.c. 
using this sort of set-up. subotnick called it "ghost electronics". the used 
the tape to store "events" as sounds and recover them as control voltages for 
performance control of spatio-location, etc.. when i saw him, he was actually 
using a bunch of serge envelope followers and quad vca matrix. as a serge 
owner at that time i was surprised and asked him about it after the concert 
and he told me that while he was perhaps the most well known buchla user in 
the world, buchla was hard to deal with and hard to get stuff from in a 
timely basis so this batch of stuff he had gotten from serge because of the " 
cultural similarity" of the system concepts.
best,
dave v.
