Hello Is it possible to fine-tune the A-110 more than the front knob allows? Right now I have the tuning knob turned all the way clockwise but I cant tune it correctly to other gear. It is controlled by the dark energy, CV1 out on DE is connected to CV1 in on A-110. Regards /Fredrik [Non-text portions of this message have been removed]

You have to reduce the value of the resistor R5. You simply may solder a new resistor in parallel to the existing resistor. The smaller this resistor, the wider is the range of the potentiometer. see also http://www.doepfer.de/a110_tec.htm Florian

Thanks I did indeed do a search first, but found nothing :-) F --- In Doepfer_a100@yahoogroups.com, Florian Anwander <fanwander@...> wrote:

Fredrick, have you noticed if you can play a regular musical scale when using your A-110 or you having trouble just to play the A-110 in tune with other synths? At the moment don't touch anything, as Florian told. --- In Doepfer_a100@yahoogroups.com, "Fredrik" <fredrik.stolpe@...> wrote:

Hello I can play a regular scale fine, but not tune it to other synts. So its the R5 change then? Regard F --- In Doepfer_a100@yahoogroups.com, "Sidney" <sidney_honi@...> wrote:

There is the internale trimmer P6, which is intended to set the basic center tuning. * unscrew the A110 from the rack * pay carefully attention, that the PCB of the module does not touch the frame (to avoid short cuts ) * connect your MIDI CV interface to the CV In1 of the A110, and the audio out of A110 to a monitoring system/mixer * reassure that no other CV is fed to the A110 or the internal cv-bus. * power up the A100 * set the tune-potentiometer on the front panel of the A110 to center position * feed the MIDI of an external Synthesizer with MIDI into the MIDI-CV-Interface of the A100. * Play a C on the external Synthesizer. * Now listen to your external Synthesizer and the A110 and set the A110 with P6 to be in tune with the external synth. * Switch off the A100 * remount the A100 to the rack. * you are done. If you want to increase the range of the Tune potentiometer anyway, then add a 470k Resistor parallel to R5 Florian

Ah, great, that's just what I was looking for, thanks a bunch Florian! /Fredrik --- In Doepfer_a100@yahoogroups.com, Florian Anwander <fanwander@...> wrote:
