and so i ordered a matrix 12; and the sight below greeted me:

…no, no ..that one silly !
quite a front panel.. a 8 megapixel slr struggled to capture the fine artwork on the front panel for a one shot overview:

rear panel funnily enough …btw the jack sockets on these things always lack any form of nut on them ..even though they are threaded for it !
aah VFD’s ..not enough synths adorned with these things ![]()
insides of course..
the immense stack of circuitary for the 12 voices …they dont pack em out like this anymore ![]()

on the voice boards:
cem3374 - dual VCO
cem3372 - variable mode/state filter ..mistaken on the web at times for being only low pass !
TL084/82/81cn - the lower cost TL series opamps.. most are probably for just dealing with modulation stuff.
tl074cn - higher performance, low noise TL series opamps ..proabably used on the audio end.
other chips and bits im too lazy to document right now.. have a look for yourself ![]()
each of the six voice cards is controlled directly by its own dedicated cpu, in this case Hitachi HD68b09p
The control surface and front end has an entirely sepperate & somewhat more bulky cpu board to string it all togeather ..patch memory and such is on here too. uses battery backup (not thedays of flash ram when this was out ;).
the cpu here is hitachi hd68b09p again.
power supply with an odd improvisation regarding a small step up transformer to provide the VFD dispalys withthe 55v or so they needto work.
Various sections of the top surface boards…weird infinate rotarys knobs based on resistive technology here:
final overview ofthe main cpu board.
some info:
The Oberheim Matrix 12 is essentially 2 Xpanders stuffed into one box with a keyboard attached. its a 12 voice instrument and sported an impressive 15 mode filter & was the first (?) synth to fully implement the powerful matrix modulation system. its amazingly programmable & for the most part easy and intuitive to do so.. and sounds pretty fat
i particularly like the 3 pole (close to that classic roland filter sound), 1 pole & phase filters this synth has ..they have an interesting timbre without stiking their necks out too far when being abused somewhat ![]()
The only real niggles are that the keyboard could be abit more responsive & the paddle controls arent great.. then again these things can be changed and tweaked for fairly minimal hassle if depended on.
Also contemplating playing with some ofthe new higher performance TL series compatible opamps to ‘improve’ the sonic character of the synth ..tho i may well just leave it be for now.. as its quite enough as it stands ![]()
btw anyone got the absolute final ROM versions for this synths voice & cpu boards ? …its a meer one step behind.
If you arent too fussy, you can get pretty close to the capability’s and sounds of this synth ..with the matrix 1000 units ..which sell for 1/10th the price typically …only they lack any controls other than patch recall, dont respond to changing parameters in realtime quickly at all ..and have a distinctly shrill bite to their low pass only filters which although sometimes works in your favour and at others hinders a completely comfortable rendering of certain sounds.
bought this one from tonetweakers.com; they service & sell vintage instruments restored to full working order/calibrations.
Took a chance on ordering from these guys on spotting a matrix 12 ..they were polite, patient & most important the order arrived as expected, and as described on their part. Go take a look sometime, they sell tons of kit & you might find something you’e been looking for.
Riiight …whos got a cs80/cs30 they want to part with ? ![]()
UPS …and the fun we had..:
all went pretty well… however UK UPS managed to really piss me off. But then again, thats not been unusual for them in my area…
friends keep on getting packages arrive severly battered & in one instance a farnell delivery had a whole bunch of serviets shoved in it to hide the fact that its entire contents had bounced around & was 'lost wherever..
USA side UPS seemed to be pretty efficient… the parcel got thru in 25 hours & as you might expect it took afew days to drip thru customs.
then the fun started… the delivery date was quoted on the online tracking as being on the 25th.. the tuesday after the easter break. Overnight in the wee hours they changed their mind & tried to deliver it when i was far from expecting it on friday 20th ..and i missed them..
having not happened to be available upon the first time they decided to randomly visit was the start of the problems…
i phoned up their single national number for the uk to find out about the fact that no customs charges had been noted on the missed delivery form.. they told me there was nothing to pay ..and they didnt seem to be able to provide me with an example of standard procedure where customs is due ..the staff just didnt know this !
the next point of inquiry with them was where was the local sorting office & what where the opening times. i said if i managed to arrange transport and it wasnt too far; id go with a friend to collect before easter landed.. but -NOT- to change the delivery options;i stated that i may not be able to collect in person and therefore not to change any of the delivery details.
…guess what ..turns out tamworth was too far an no one was available ..they canceled my 2 remaining delivery attempts ..defaulting to 5 days hold & return if i didnt appear !
what really rubbed it in, was that only after 4 very cool headed and clearly stated phone calls did the several different staff i spoke to finally get booking it back in for delivery again ..the first one on confirming my reuest for re delivery managed to press a button that just puts it on hold again …is this computers, people or both ? …honestly.
i only got it sorted propperly when i managed to get them to forward me to the local sorting depo.. (no public phone nmber for them (unlike royal mail)) …this was then somewhat reluctantly sorted by them there.
next on this one; the delivery arrives on this thursday, nice enough guy working on their delivery rounds
…he hadnt noticed the automated slip that stated the customs duty to collect immediately in person til i mentioned duty fees..
and somehow, despite that info being available on ups systems.. the call center wasnt able to inform me of it ..or to be aware of it ! ..funny considering the customs fees are sorted for them by someone on the uk side they emply to do this ! ..and they didnt inform me of how they dealt with customs …even though there was that pink slip sitting there, printed by them ..in the uk !
the delivery chap said… yep they are always doing this …they never tell us ..or the customer about customs charges.
furthermore, the delivery drivers aren’t actually insured to collect customs duty for them ..royal mail couldnt get renewed insurance for theirs …so they canceled cash on collection in preference for people paying over the phone to clear parcels for delivery/ relying on them turning up with cash at the depo in person. ..but at least royal mail have the decency to send out a letter stating the required fee ..rather than demanding a fee out of the blue on your doorstep ..and if something you werent expecting arrives levying customs duty from someone like ups ..theres a fair chance they wont let you know what it is first before forking out…
also not having all the money to hand for the duty meant that the guy had to come back the following day..this friday before we were able to close the deal.. which resulted in a spoofed ‘closed for business’ thing being left in the system ..making me look even more of a prat in paperwork terms..
.needless to say …i dont like ups.
tho somethings we have to put up with occasionally ..and if not anywhere else ..the midlands sorting office sucks.
