Vintage Synth Repair

Any Axxe owners on the list?

I just got around to repairing an Axxe that i've had on the shelf for
a bit.
The main issue was a broken trace in the cv memory circuit.
The keyboard now tracks correctly and the portamento works too.

The s/h circuit seems odd though
According to the service manual, when you engage the the s/h switch
the noise source is connected to the memory circuit and key cv buss
is routed directly to the vco mod in. all of the has the effect that
while key presses do offset the vco pitch, that offset isn't held or
memorized upon key release. So when the key is released the vco then
returns to it's base pitch which is determined by the tune knob and
the transpose switch.


If I recall correctly that's how it is, yes. The only solution is to set
Release to zero.
