Hi,
I've had some time to study the schematics now and I have some
specific questions to confirm my understanding of the circuit before I
commit to buying. I have a Doepfer A-155 and knowing that this is my
starting point might help understand what I'm trying to achieve with
this Programmer.
1. I'm not sure I understand how to limit the number of steps in the
sequence and what exactly the Ext Pulse does. For example, if you
want to run from steps 3 through to 7, would you patch the pulse of
step 7 to the Ext pulse of step 3?
2. With respect to the push buttons, do these act as a "reset to this
step" button?
3. Would wiring a debounced, push-button from the +15V to the up (or
down) input (as suggested in an earlier post) act as a one step advance?
4. On the A boards, pulse out circuit, could all stages be wired
through switches to a single LED, 820R, pulse-out and 680R? The
reasoning behind this is to replicate more conventional sequencers
where each row of switches goes to a single indicating LED and socket.
And then add four rows of switches.
5. What voltages do the pots put out (at 12V if anyone knows,
otherwise, at 15V)?
6. What voltage do the stage pulse outs, the CPO and AEP produce? Do
the stages produce a trigger or gate?
I'd appreciate greatly if anyone can answer these questions.
Yours Aye
