Matrix's and Xpander OS goes a bit bonkers at times. Try a complete reset. It certainly helped me when I had problems with tuning/processor malfunction errors and the like. You might have to back up

I booted up my M12 tonight and can't get anything to pass tuning. Any ideas what I should check for? Likely a failed logic chip inside, but how would I debug?

Was the basttery- I replaced with one of these and all is well again, :) CR17335SE LFU - FDK 3V CR 17335SE, 2/3A, U-L?tfahnen jetzt f¨¹r nur 4,30 € bei reichelt elektronik

My m12 had the exact same symptoms it was the battery and a new one fixed it

My xpander is having a bit of a wobble- when I power on it goes to the reset page: it boots to 'reset memory? doesnt affect patches' Of course, it has killed my patches- the display is showing wonky

hello karl , very nice for support .. yu are electronician, musician ?? i learn electronics slowly , i'm musician, but i will learn your info with the schema for my theory practice .. maestro

Hello Ian, ? I have a different PSU in my M12. Aside from a buzzing transformer it works fine. The following coments,?come from looking at the xpander schematics. ? The?transformer may not be bad.

hello everybody, I have a problem with PSU too since 4 weeks.. 2 technicians check it, replace resistor ( R17 was burn, R4), capacitor, transitor Q2,Q3 .. order and change NE 5561 on U4, then mosfet

I have looked at?doing this, but increasing the micro speed is not all.? The analog multiplexer circuit ultimately determines the update rate of each parameter eg..? env attack etc...,? which in

PeWe you cannot make ?em faste. tasks where Xpander/M12 fail. Welllllll, Hitachi makes a pin & instruction compatible 6809 replacement (6309) that runs at 4MHZ, but it would require a partial rewrite

agreed, the machine is about complex modulation. if you want a click/bass snapyness, then use something like a shruthi from mutatable - it's so hard and jabby it will take your eye out.

you can modulate a ramp with a ramp and obtain exponential ramp

Thats why I said "fuget it" ... Components and software inside Xpander(M12 are as fast as they are and you cannot make em faster. Use the machine for what it can do excellent and use other gear for

But I heard that the xpander's processor acts quicker if less routings are enabled. It's logical cause the processor is so vintage. I even saw somebody wrote that applying one envelope a several times

i know you can route multiple things to the same VCA and maybe by doing this you can trick it into moving faster than the normal VCA setting allows? ? i remember this conversation happening on AH or

yes use ramp for quick pulse

well, when you define "snappy" as being the problem, that won't have anything to do with the characteristics of the oscillators. that has everything to do with the response time of the decay on the

Ramp routed straight to the filter ? Very interesting. Gotta try it soon. And to my ears the problem also is the fact that xpander has weaker soundung oscillators than a discrete old moog of course,

As PeWe stated, you're not going to get Minimoog fast response times from any of the modulation sources. However, while this is one of those things that subjective to personal taste, you can still get

One of the designers of the Xpander and Andromeda is Marcus Ryle. That explains a lot. Andromeda developement is younger, so yes, theres a different processor inside. Xpander uses the same processor
