Re: Intro and questions

 

Hey, Thanks for that, Ive spoken to a couple of those people already funnily enough (benden and synthparts. You think the DAC is worth having a spare one of too then? Is there one of those inside or 6 do you know?
The guy who teched mine didnt think Id have a problem with the screens, think its been in storage for a long while- they are very bright and have no fading anywhere. I might grab one of the benden ones on the next run just in case, its great that he did that. :) Be nice if someone mass produced another run of CEMs just to future proof us but I cant see that happening.

check some of the vintage parts suppliers:

I just checked and synthparts have them in stock, they also have the HS3140C

My tech buddy built some replacement display boards for the xpander, check
it out:


Hope that helps!


Hello, finally got hold of an xpander last week, absolutely love it. Some of my first sounds out of it here:

Im not really a vintage chap but I make exception for the XP, always amazes me that no-one has ever really topped it in the 25 years it has been out. I guess the andromeda came close but since its not a desktop synth and looks like a mid 90's car stereo Im ruling it out.

Anyway, Ive a few questions:

CEM's- anyone know of anywhere with a few spare VCO and filter chips. Is that all I should be stocking up on or is there anything else prone to faliure?

OS- Im not on the most recent OS (think Im on 1.0 and 1.2), everything is running perfect so Im tempted to leave as is- is there anything Im missing out on by not upgrading? Was it just a bug fix upgrade?

Manual: I have a PDF I can print though I was wondering if anywhere stocks printed & bound manuals?

Cheers,

And that?s why I bookmark your post and now wait for your Xpander OS upgrade upload within 3days.

Re: Why no Xpander mod. matrix implementation?

 

The only difference in the front panel is an extra button and led to toggle
between the

voices 1-6 and 7-12. ?So thinking about just adding the firmware from an M12 and
then switching off

the unavailable voices sounds plausible at first, but:
The Xpander has CV ins, which the matrix 12 lacks. So if?even if someone copied
the ROMs from an M12

and?was successful in getting?it to work in an Xpander.?you would still lose the

As Tony suggests it would have to be a custom rewrite.

I was wondering why the M12 mod. matrix was never retroactively implemented in
the Xpander? It's all software, so it seems like an update would've been easy.
(And "Name" is just so lonely in the Misc page:)).
Re: Why no Xpander mod. matrix implementation?

 

Never mind. I thought the M12 has an extra display ;-)
In that case- you've got a good point. I wonder why they didn't make a FW update for the Xpander.

Sounds like a job for Neil Bradley.

What do you mean? They both have the same displays.

The suggestion about copying a patch to six voices, then detuning each, is a great workaround for the lack of individual voice detune (on a single patch). I think that's available on the Matrix-12 but not the Xpander.
No, it is available on the Xpander, I've done it myself.
Note: I meant copying the patch to 6 voices is possible on the Xpander and the Matrix 12.

But I agree the Xpander doesn't have the Matrix 12 feature you describe.

Thanks to everyone for the responses.
Re: Chaining multiple Xpanders

 

I think you're correct Jeremy, but having more voices appears to be the primary concern.
Not being able to detune each channel isn't such a limitation

The problem with a Matrix 1000 is you can't detune each channel. For
instance, on the Xpander you copy a patch 6 times, make a multi with
those 6 voices, then detune each of the 6 patches. Then you get a really
layered sound.

You can't do this on the Matrix 1000 because it doesn't let you have a
different patch per channel in unison mode.

Correct me if I'm wrong!

Jeremy.

Youre free to use several Matrix-1000,- each one on a different MIDI channel, each one plays the same or a different sound, each one set to unison if you want and play em simultaneously that way,- if you use the right MIDI controller.
You can detune every Matrix-1000 against the others,- theres a master tune parameter.

Also,- youre able to play up to 6 Matrix-1000 in Group Mode (page 29 /Chapter 4 in the manual).
All will be controlled by the group master ... but:
"other changes like fine tune must be made on each unit individually" (page 30).

This has nothing to do w/ the mono/guitar MODE where separate voices of ONE Matrix-1000 play on 6 different MIDI channels.
Channel MODE, page 20 of the manual ...

I seriously doubt it. You'd have to modify the firmware to do that, and chances are the CPU's are already maxed out.
You can already hear the CPU's lagging when complex modulations are used, when the user turns kbos on the front panel.

easiest way,- own 2 or 3 Xpanders and a Oberheim XK ...

But you can do that over midi w/ every MIDI controller transmitting MIDI via 3 zones on 3 MIDI channels (or more) simultaneously, depending on how many Xpanders you want to link.
"MIDI Echo" bypasses MIDI info from MIDI In to MIDI Out,- like MIDI Thru, but adds all parameter changes you perform on the 1st ( master) Xpander to the "slave" Xpanders via MIDI Sysex,- MIDI Merge.

Oberheim XK offers arpeggiator (w/ analog clock sync) and original levers,- something you don?t find in modern controllers.
Preset memory system fits Xpander / Matrix-1000 perfectly.
I have a somewhat cusomized XK,- but I?m fine w/ a Kurz PC361 too.
It?s a most excellent controller.
