Matrix-12 SERVICE ROUTINE questions

2017-07-17 by ipc.de@...

Can somebody out there give my some insights and hints on the following issues?


(1) With UNTUNE VCOs of lower voice board sound about one octave (1.2 Volts) lower than VCOs of upper board. Are there different default values for lower and upper boards? Same O.S. installed on both boards.

(2) DAC OFFSET service routine only works with lower voice board. How to adjust DAC offset on upper voice board?

(3) Coding jumper decides which board is "upper" , which is "lower" . Is it possible simply by way of swapping jumpers to make upper to lower and vice versa?

"Hi,
The UNTUNE VCOs option typically sets the tuning to some random number and should not be used to set a default value."
