Omni 2 readable service manual?

Omni 2 readable service manual?

2013-02-01 by Jim Blair

Hey guys,

I'm in a bit of a bind at the moment. I have a session next weekend 
with a keyboard player who really wants to use the Arp Omni 2.

It's pretty dead, and the tech can't find a clear schematic. He has a 
service manual that I've found online, but when he magnifies it, the 
values and small text become unreadable.

Anyone here have something that will help us on short notice?



Thanks!

Jim

Yes, Jim, I have an original OMNI-2 service manual.
How can I be of assistance?

Thanks so much. I did end up finding a pretty clear one. My tech seems happy, and that's saying something.

In case it would be of use to others, here's where I found it.

I like you was unable to use the Omni 2 manual that is in circulation. I bought my own copy and did a hi rez scan. The scanner wasn't perfect, but it came out much better than the other version. It's available for free download here:

http://rcarchives.com/swirlies/manuals/index.html

I also have many other goodies not on other sites. Most are my own scans.

Korg MS10 service manual?

2013-02-10 by Jim Blair

Hey!

I picked up a very cheap, but mint, MS10 today. Looks brand new.

So it works great, and sounds amazing, but needs some pitch 
calibration. The upper end of the keyboard is a bit flat.


I've been looking around for the service manual, but have only found 
the owners manual. Any suggestions?



Thanks.

Jim

Roland S10 sampler.

2013-02-13 by Jim Blair

Does anyone have a copy of the free "S10 Manager" software? The old 
link doesn't seem to work.

I've ended up with a working S10 (free), but no sounds onboard, and 
no quick disks.



Thanks!

Moog Source calibration.

2013-02-20 by Jim Blair

Blah.

Actually, two hours of blah.

Following the service manual, but no success.

Anyone have some tips and tricks? It's all about tuning oscillator 2. 
It's just not stretching sharp enough up the keyboard.
The front panel Osc 2 calibration doesn't really help much. 
Internally, in order to even get close, I have to have Scaling and 
High End Compensation all the way to the left, but the upper end of 
the keyboard is still flat. No room left to stretch the pitch out more.

Osc 1 is fine.



Blah.



Jim

Re: Moog Source calibration.

2013-02-20 by Quazimodo

Jim,
I'm not familiar with the Source... but could you not bring the overall pitch of Osc 1 down a slightly..? Then retune Osc 2 to it?

Just an idea...
Cheers,
TOM

2013-02-20 by Jim Blair

Thanks for the replies.

It's not really a "tuning" issue, it's the stretching of the pitch across the keyboard. When the low note are in tune, the high notes are flat, and I'm at the limits of the range of the Scale and High End Compensation trim pots.

you need to change those pots
that happens on the memory moog also the pots become bad over time and go out of range finding it hard to tune them

Hmm... 
 My Source is in the shop for a calibration and battery change and there were some keyboard scaling issues as I recall. Good luck with the fix. Any signs of battery acid damage?

Re: [vintagesynthrepair] Re: Moog Source calibration.

2013-02-21 by Jim Blair

So this was our solution.

We replaced resistor R77 (double check that, I don't have the synth open in front of me. It's above the scale blue trim pot), which seems to control the range of the scaling on osc 2, with a 4.7k.

Works perfectly (so far).
