Yeah, that tends to fix the problem. To be fair, there's a lot pulling from that power strip -- it's a 44 space rack.

I wish someone would do an NRPN OS upgrade for the 6 and 6r like they did for the 1000.

I’ve seen the gibberish on the display thing before on my original M6 even way back in the day when it was new but the sound still worked if I remember correctly. Shutting it off for a moment and re-starting usually fixed it. Without playing around with the unit, don’t really have any guesses as to why it might be silent. You might try a Master-52 calibration for starters if you haven’t already.

As far as I can remember, OS 2.15 improves the real time sysex response for folks looking to have smoother changes when using knobby editors and so forth.

Subject: Re: [Oberheim] Items for sale ok?

Thanks for feeding into today's procrastination efforts.

So, I purchased this M6r a while ago with one bad oscillator in voice 3. I thought it just needed a master-52 style calibration but I was wrong. The issue was that the one oscillator did track pitch kind of, but it was the wrong pitch.

I had an old 4 channel Tektronix scope I used at first but I wanted something a bit more modern so I picked up a new Hantek 2-channel scope for like $200 and sold the old CRT scope for like $200 - who knew?

After downloading the CEM 3396 datasheet, I looked around with the scope at the various signals and found the CLKA3 and CLKB3 signals that control the frequency of the DCOs in voice 3. I played 6 notes on the init patch but I changed the voice assignment to rot so that I would have all oscs playing the same note. Remember that the oscillators are always oscillating even if the VCA is closed.

So, with this configuration, CLKA1 - CLKB6 should all be the same. When probing I found that CLKB3 was not the same frequency as all the others. I then went down a rabbit hole trying to run the resonator calibration procedure in the service manual but that was useless - why will be apparent in a moment.

CLKB3 is generated by U728 which is a Mitsubishi M5M82C54P-6 programmable interval timer. The M6/6r have three resonator circuits that run at about 3MHz (IIRC) that clock the the four 8254s - this is the big difference between the 6 and the M1k - only one resonator for the whole instrument and why I couldn’t quite use the schematics for the M1k of which there’s a hi-res digital version available. I did find a high enough quality scan of the original hand drawn M6 schematics from Oberheim where you can actually read the tags. After checking, all the resonators were running within spec.

Signal FBU on the schematic is the 3MHz clock from the resonator that runs the 8254s and is assigned to oscillator 2 of voices 3, 4, 5 and 6 (CLKB3, CLKB4, CLKB5, CLKB6). Since all the other oscillators were in tune, it’s definitely not the resonator.

I didn’t get too deep into the how exactly the 8254 chip is used but it’s either going to free run at a particular frequency until told otherwise (which is probably how it’s used) or it has to be reset every time the programmed interval time is reached which would be quite processor intensive. Doesn’t really matter though. The 8254 chip only has digital inputs other than the clock input so that lead me to believe that the 8254 had gone bad or possible a trace or pin or something had gone bad on that particular one as all the other timers were working fine.

Just to elaborate a bit on this for folks with less ECE experience as this is the actual moment of diagnosis and how I figured it out- there’s only one data bus from the microcontroller (MCU - 6809 in this case) that is shared and talks to all the chips with digital inputs. There are also chip select lines to make sure the MCU is talking to the right chip - the MCU selects the timer chip - writes a few bytes of data and moves on to the next thing. If the other timer chips are working, and the only control of the chip is on the data bus, the data bus signals themselves must be good…which means that the timer chip must be bad.

I de-soldered U728, popped in a socket just in case and put in a NOS or possibly OOS replacement chip I found on eBay and boom - synth is fixed. It was really quite satisfying to fix as this mixed digital/analog stuff was what I was really really good at in school and never really got a chance to use it (school was a LONG time ago). Shoulda moved to Cali and found a job at a synth place when I graduated I guess. Instead, I think I’ll look for more M6s to repair as I know it quite well now and maybe expand out a bit as a hobby.

I'll pop in a socket for the battery and probably upgrade to 2.15 if I can find it before I sell.

Thanks Daniel and Nicole.  I had both Midi-OX and Midi Quest open at the same time.  Once I shut them down, all is normal.  So, yes Nicole, it looks like I was sending and receiving notes at the same time.  Thanks for the help!
Re: Matrix-6 Polyphony

Nicole Massey
 

Is this a keyboard matrix 6, set up in a MIDI rig? If so and local is still on, it may be playing a note and also receiving a note, which would do that. Does it do that when under a sequencer, or is it just when you play the keyboard on the Matrix 6?

When you strike one key on the Matrix-6, you will notice one dot or "period" light up on the display. If you strike two keys, then you should see 2 dots or "periods" on the display. Currently, if I strike one key, then the display shows two dots or "periods". This is literally cutting my polyphony down to three notes instead of 6 notes.

There are many different sets of M1000 patches and factory patches floating around. Some of you may have noticed that some of the factory sets were incomplete or duplicated.
Don Solaris has retrieved and sorted the full sets and those are now available for download.

As a bonus, there's also a Reaper reabank set available for the Bank 0 & Bank 1 user locations.

[UPDATE] 
There appears to be confusion about where to access file downloads from.
Look to the left, click on Files. That is the storage area on Groups.io for related file materials.
Files hosted there are already divided up into different sections for different models and usage cases, including for the M1000.

Inside Files, click on 02_Matrix1000. That is the section which hosts M1000 related files.

Inside 02_Matrix1000, click on item 10 which is already labeled as the Don Solaris retrieved set.

To reiterate my last post, Laser Mammoth has the original factory bank available from the ‘Public Bank Library’.

 

https://f0f7.net/fe/#/SysexLibrarian/OberheimOb8

 

It’s FREE! I have chosen to upgrade to a Pro account as I want to store more banks but if you just want the factory bank, it’s there, waiting for you, for free.

 

Full instructions are there …. not sure what else I can say!

Thanks to all for your help in my search for sysex files of the original patches for the OB-8.

 

FYI, I would be sending the sysex from a PC and am now trying to find info (manual and sorts) on sending

sysex TO the OB from the PC (commands, setups, etc).   I was sent a sysex file, but I am not sure if it's an entire bank dump or

individual patches (for my OB does NOT have the Encore midi setup or Kiwi??).  My OB has MIDI (installed well after I got it).

 

If you all wouldn't mind, I'd like to get this Sysex in both formats:

  • Individual patches
  • Entire patch dumps.

 

Any help and other info on sending sysex to the OB  WOULD BE GREATLY appreciated.

 

Thx!!

I use the fabulous Laser Mammoth for full sysex dumps to/from my OB8.

Mine has the Oberheim retrofitted Midi board.

Thanks for the file.

 

I heard/read that the OB will only send 1 patch at a time via Sysex.

That the Encore midi interface kit would allow the synth to send ALL patches at once.

Hi, I found this file with the factory patches for the OB-8, but I wasn't able to send them to my OB-8 with the factory midi interface installed.

I know with an old mac with System 9 (or earlier) and Opcode Galaxy I can get all patches or save an entire bank to the OB-8 but the file I've found is not suitable for Galaxy (it's a .syx file).

If anybody knows how to send all patches, please let me know.
