Doepfer

hi all,
  
the important (and relevant to Doepfer A100) question:
 
since it looks like (to my ignorant eyes) that the SH7 
'pedal vcf input' (seems to be powered) works like a simple variable resistor (i guess that i can 
simply connect a variable resistor to this input to change the filter cutoff), 
could i use the Doepfer A101-9 Universal Vactrol module, to 
operate the SH7 filter without any modification to the synth? (using the 'vac 
out' connected to the SH7 'pedal vcf input')
 
here is the link to that module:

here is a link to the SH7 service manual (thanks 
CEM3374 !) :

(check page 24 and the vcf circuit page, to see how 
the pedal input is...)

if this cannot be done, any help on converting the SH7 pedal vcf input to a regular cv input?


many thanks in advance for your help!
 
best regards,     :-)
Bakis.
