Using A-155 with ARP 2600

2007-06-25 by longforparade

Hello list,

I am thinking about putting together a small A100 system in a portable case to use for 
sequencing/expansion for my ARP 2600. I have a few questions about the A-155:

-How "hot" are the trig/gate outputs on the A-155; does it put out the +10V required to 
trig the 2600's envelopes? Otherwise, does anyone know if there is some simple mod that 
could be done to the A-155 to make the trig/gate outs put out this voltage?

-I would also like to extend the cv range of the two sequencer rows to 0 - 10V to be able 
to, for example, open the 2600's filter or VCA from minimum to maximum. I suppose this 
could be done quite easily by amplifying the cv outs through an A-133 polarizer [?], but 
has anyone tried an internal mod to the A-155 to extend the cv range?

All help most appreciated!
