Hi Steve, you can count me in as wanting a production board! -- Amanda SynthSights! "it's not about the gear" Come join us! Info. at: www.synthsights.net *_ |_) _ _||\/| _ _ ._ www.cikira.com |

My Xpander was working fine (I bought it new in the late 80's). I decided to put in a new battery (I was in the process of changing the batteries on a bunch of my gear) and did so. The operation

Hi, I'm new here, so perhaps I should introduce myself. My name is Steve Lenham and I run a small design consultancy in south-eastern England, an increasing part of which involves working on classic

Karl, Thank you for the tips, at least I can hear the quantize effect. I reached my geek quest ;)

Hi, I had to go through my patches to find some patchs using quatize. It seems AFAIK the quantize function is most useful when modulating the frequency of a VCO. As you point out it is hardly

I found the differences between these messages. It's only about how to activate/desactivate the quantize: - action=06h "toggle" simply toggles the actual quantize. If it's ON, it will go OFF and

How about sending one of those messages via midi, save the patches (before/after the messages), to see which bit(s) are set or cleared (if any). Repeat with the other message.

Hmm, that's an interesting question. ? My guess is that applying quantize to ANY mod produces identical quantization as compared?to a mod routing with the keyboard as the mod source?with a mod

Hi, In the modulation pages of the Xpander, it's possible to set a quantize option to themodulation. The manual of the Xpander says, "Quantizing cause semitone steps instead of a smooth change of an

Hi Takis, Looking at the data sheets These two parts( MP7614KN and HS3140C) are the same, and should be interchangable. If you have an output of 4 V on PIN 6 of the opamp(U815), then the op-amp could

Hi Takis, Could Be, What happens if you put the old one back in, And check it's calibration, from pin 6 of U815? Karl <takisdamaschis@...> wrote: DAC calibrtion

Hi Karl, I did the calibration procedure but unfortunately I can't get the DAC trimmed down to 0volts!It keeps showing 4v(pin 6)! Does that mean that the DAC is faulty?

Hi Takis, On page 34 of the Xpander service manual there is a DAC calibrtion procedure. A different chip would need a calibration. What about the reference voltage? Karl <takisdamaschis@...> wrote:

Hi Karl, I just got the new DAC! It's an HS3140C.I installed it and.....nothing!Every test fails now instead of only some VCO's! My original DAC is an MP7614KN, are these two incompatible and if so

Hi Tony, I'm talking about D805 at the DAC circuit! wrote: procedure) <takisdamaschis@...>wrote: "Karl"

Hi Takis, I measured the D805 in mine: 6.95 Vdc. I notice it's a diode in a transistor package. This is a very accurate reference diode. It should read at least 6.9 Volts. Pin 1 is not used. I

Hi, are you talking about the D805 diode? If so, mine does not have a capacitor parallel to it! Did yours have one all along? If so please let me know of it's specs so that I can add one myself!

Hi Karl, the voltmeter reads 6.38v! Takis.
