Re: [Doepfer_a100] A155 factory-fitted revision

2003-03-12 by Bakis Sirros

hi tim,
if the mod is a resistor and a capacitor in the a155
control board,then this is the mod i was telling you
about...it's the mod for letting you clock the a155
from an imperfect clock pulse(with not sharp
edges).also,with this mod ,you can step manualy the
sequencer from the tiny step button more
properly(without almost jumping
steps...).but,also,this mod stops the a155 from
running in high audio frequencies!even if you clock
the a155 from an a110 you will notice that,the a155
can't run above a certain speed limit(which is rather
low!)all these are valid only if we're talking about
the same mod,though....
by the way,i removed this mod from two of my a155's
because i want them to be graphic vco's too!
bakis.
