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.

This seems so weird that I just wanted to ask if anyone else had  
noticed this.

Portamento in s/h mode doesn't behave as expected either, so maybe  
something else is broken or shorted...
