C knob controlling master volume

Postby drmnaga78 » 19:22, 27 February 2017

Hi again, sorry for all the noob style questions! Having some weird issues with the C3 knob. Was working on a song using some mfx's then noticed not only was the C3 knob controlling the allocated parameter that I set in knob assign, it was also controlling the over all volume. Tried different routings, didn't seem to make much difference, got worried that the previous owner had hardwired the C3 knob to replace the master volume knob(as it is pretty knackered). Thought I would try starting a new project, thankfully all was cool and back to normal. But now it is doing it again, pain in the arse! Any ideas kind MV folk?

That´s odd...never heard of such behavior before.

Did you try initializing the MV?

EDIT: Found this in the service manual, maybe it´s of help to you:

Odd indeed, switched it on this morning and all is cool again, C3 is doing what it should again!
I initialised it when I formatted the hardrive after I bought it. Thanks for the schematic, where can one get the service manual from, might be helpful as the volume knob,f5 and shift button are all a bit worn out.

I only had to change some sliders so far. Changing the parts was easy, getting to the PCB was a PITA, though...

I´ve documented the disassembly here: viewtopic.php?f=9&t=52205

That is helpful. Looks like the buttons, sliders and knobs are all mounted to that last PCB in the pics?
