Re: [Matrix-12] All Voices Fail Tuning on VCOS, PW, RES, VCF, VCA

 

开云体育

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 first though...

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?

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 characters and they are all over the place. Otherwise it is working fine once booted- passes all tuning tests and service tests. Everything seems fine... I even manually reset all patches to the Oberheim preset... same issue on startup.?


Any ideas? Might it be something simple like a battery? I hope so!?

Re: PSU Transformer

 

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 Dirstein just repare my xpander , better with a pro .. even if it coast a price ..

xpander had some injurie from non specialist those last week ..
let's see if psu work in time , i'm very to get it back..

i have good schema for xpander with color if yu need ..

best vibes ian?

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.
Checking if T1 is working should relativly?easy.?
?
To test the primary (input)?of the transformer:
Unplug the mains cord from the Xpander.
Place an Ohmeter across the mains input on the back panel with the power switch on.
You should get a high resistance reading but not an open circuit. If an open
circuit, the the primary (input) of the?transformer has burned open.?
?
Unsolder diodes D1 and D2?and remove them from the circuit.
this allows isolating the transformer output from the rest of the circuit
?
With power off:
Measure across outputs of the transformer (secondary)?with an Ohm-meter. If the reading is open, then the transformer is
dead. If good the transformer ohm reading should be a low value (something less than 10K ohms).
?
Best Regards

Re: How to make snappy bass on Xpander ?

 

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 turn?limits the speed of the mod souces.? So.. the resistor/capacitor values in each mux circuit (one per voice) would have to be changed?along with the code.?I would?hate to hack?up my?M12 that much.?There is an AKAI out there
that I believe?has the?same CEM chip set.?It might?be a better victim.??????
?
BTW?? Putting a a sharp, short ?evelope to the FM at the beginning of the?sound can add some snap or bite to a bass patch.? Learned this from an artical?by Wendy Carlos.

PeWe>>Components and software inside Xpander(M12 are as fast as they are and you cannot make ?em faste. >>Use the machine for what it can do excellent and use other gear for the 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 of the firmware. (I'm not sure if it is the exact same model as the 6809 (B vs E) though).
Additionally, there is another mode in the 6309 that has a few "extra" instructions which enable some operations
to be even faster. But this would cause more of an incompatibility until the FW is re-written.
However, if any of you are tired of the Xpander/M12's current limitations, a challenge awaits ye.... ;-)

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 to the same destenation helps.

Re: How to make snappy bass on Xpander ?

 

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

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 ADSR when routed to the filter cutoff. so yes, try using one of the RAMP generators to modulate the filter cutoff instead of one of the ENV.?

otherwise, yes, you don't get quite the same low end "bottom" on an Xpander as you do on a Minimoog. but that's the beauty of these machines, they each excel in their own areas and what provides a wider range of "color" for writing. personally I find the Xpander great for bass sounds, particularly for more aggressive "grittier" bass sounds when using the 1-pole or 2-pole LP filter settings. from there it all eventually comes down to your programming and how it is mixed in your track.?

Re: How to make snappy bass on Xpander ?

 

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 some fairly nice percussive and snappy bass/percussion sounds from the Xpander. ? I'm not in front of my Xpander now, but I believe you could get "better" results by using one of the RAMP generators to modulate the filter as an attack/decay versus an ADSR.?

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 as Matrix-1000,- but 2 of these.

But take it as it is because you cannot change the physics.
You have a Minimoog D for such sounds.
