I once tried to re-wire a guitar volume pedal to hook to the pedal inputs to my M12.? It worked, but only in a really narrow range (like the center 1/4 of the pedal's travel), it was "railed" beyond

Thanks, I will try replacing the capacitor first. Hopefully that will be the cause of the problem. ktfiz

Your very welcome, Jeff Karl voice and it

HI thanks karl. it worked. I replaced all the 2.2 caps in that voice and it tunes fine now.. thanks jeff

Hi ktfiz, Lets hope it's not the AD7523. This part is rare anymore.I would bet it's the bypass capacitor Cx02. Where x is 2,3,4,5,6,7 depending on the voice number. It's a 2.2 uF @ 50 V electrolytic

Hi, One voice on my Xpander does not seem to respond to the addition of FM, otherwise it functions and sounds fine. All six voices pass all the self tests. From the service notes, it looks like FM is

Hi Takis, What does the your voltmeter read when you measure the zener(D805)? I keep thinking it's something to do with this circuit. I am going to open mine up and see what I get. Karl

the a little and the problem analoguejeff > Hi Jeff, If you feel good about working on your synth/soldering etc. I beleive this is an easy fix. There are two bypass capacitors which each VCO voice

Yes, a pedal in general is just a pot you move w/ your foot,- but this not only for "volume" ... Manual says clearly: Pedal inputs for PEDALS or FOOTSWITCHES. All common momentary switches work as

Sorry, but I have connected a momentary ft.-switch AND a Oberheim OBX-P pedal ( not switch ) at my Xpander here. There are differences between "Pedal Inputs" #1 + #2,- both work like Levers 1 + 2 but

Yes- but these will only provide on/off type of modulation, not a smooth transition between a min and max value, like a pot would. Perhaps you could smooth out the threshold between the on/off using

Hi Tony ! It?s possible to connect momentary switches as also pedals w/ a pot inside to the Xpander. A Moog CV-pedal Modell 1120 p.ex. or a Oberheim OBX-P pedal. Both, switches or pedals, need to

You would have to assign Pedal 1/2 to a CC#. But I believe pedal 1/2 are intended to be used as on/off switches, not sources that can vary a signal, as in a volume pedal. I may be wrong. If your pedal

Hi folks, I recently bought a stereo volume pedal with a stereo 1/4" jack on it, and it's not working with the Crumar Toccata I have. But will it work in Pedal Input 1 & 2 in my Xpander? I'm confused.

HI, I just started getting a failed PW message on voice three on the xpander. THe voice still sounds fine when I reenable it. IT is just a little quieter.. I went thru a swapped all ics with the next

Hi Karl, done everything you pointed out,no improvements! Anything else you can think of before we go for the DAC? Thanks,Takis.

Almost forgot. MIDI enables: SYSTEMX XMITCV PATCH all On Jeremy.

Hi all, I just wanted to share that I tried Soundquest 10 again for editing my Xpander and it worked! One useful trick is you crank up VCA2 so the note plays all the time, and edits then are
