I'll make one today. After spending some time with this new calibration, I'm liking it a lot!! It allows you to have more nuances over shaping the sound. Pretty delicious stuff. I think the Korg reissue had a lot more potential to be even better. But right now the instrument sounds definitely more vintage and closer to the original one.

I still think something was off though. Because before filter type II was more resonant than type I. It should be the other way around. And I'm sure everyone was like " I can't hear that much of a difference between these two filter types but I'm gonna pretend it's ok".
Even on KARP Odyssey filter type differences are drastic. On 2600 this being so subtle didn't feel right to me quite honestly.

That's also very much possible. But remember; the punchy bass sound of Minimoog was also a mistake...

Well, should be easy enough to check. My scope is out on loan, I need to get it back and check it out. Should be easy enough to verify the gain setting using the procedure in the service manual. Will be interesting to see the wave shape once the gain is pushed a bit.

Might be able to get a quick measurement using a Multimeter and a sub-audio square wave as well.

That would be awesome. I don't have any of those gears.

I haven't been on here in a while. Sadly I get to play my ARP on the weekends as lately I've been coming home beat from work. I was looking for a sequencer for it, and came across this just now:

A leak of a new sequencer and a photo of the ARP 2600 mini it seems

https://www.synthanatomy.com/2020/11...2600-mini.html

Already being discussed on it's own thread: Korg is making smaller 2600 after all?

Just checked my Karp with this procedure - from the factory mine is calibrated pretty close to unity gain. VCO1 square out is about 10v-pp and through the VCF output is about 11v-pp. There is range on the trimmer to adjust up to 16v-pp

Also note that increasing the gain trimpot for the filter will also make it self oscillate earlier on the resonance slider

Hope the gate in the new korg sequencer is strong enough to trigger the 2600 - the specs say it’s max 10V.

That’s a pretty large overdrive capability. Did you leave it at unity gain?

Oh No...!!!
Did Behringer just screw up their own 2600 clone filter?
Damn, that sucks..:facepalm:

hey guys
I've received my Arp, serial 1121.
Great stuff but.... my spring reverb seems to be damaged
Anyone had the same issues?

http://youtu.be/pOZRy1pEJb0

I also received mine very recently, serial number in high 1100s, also made 07/2020 - spring reverb is fine.

There are reports of a number of different issues. What's with quality control these days?

Ahhh you must have got one of the earlier prototypes. ;)

seriously though
i mean it's supposedly limited production and handmade right? these things shouldn't slip through

I had to use a step down converter from 220/240 to 110/120... to not have lfo noise in the spring reverb ( you can hear the LFO cycles in it, a common problem )..... and in the past few days have rediscovered that my AR envelope is not working correctly ( it never has ).

In the VCA section when I put the slider up for AR only, it uses the envelope from the ADSR not the AR.

Better check yours.

Contacting my distributor as we speak to have the Korg techs fix it.... if they will even admit to anything wrong. They denied anything seemed wrong with the spring reverb/lfo noise..... there's no way to deny a malfunctioning AR envelope but I bet they will try. They were still willing to have a look though... maybe to 'secretly' fix it without openly admitting to a production issue that would have to include some kind of expensive recall / fix of many units with shipping costs!

Annoyed for sure. This is not an easy thing to ship around....maybe that's part of the issue with these. potential damage in shipping?

🤦‍♂️I corrected it, thanks

thanks for info - i've sent an email to thomann as well and i suppose they shall in their turn forward it to korg, and we'll see. my AR and ADSR slider's work as they should, no problem there. the only issue i have found at the moment is the spring reverb, hopefully there isn't anything else.
Our voltage here is 220/240 though so it shouldn't be a problem, right?

Many of these have arrived broken and Korg is saying that the actual spring is discontinued. It is a Belton 2 spring unit (BL2). A drop in replacement would be Accutronics 4eb3c1b. It seems people are having better luck getting the dealers to remedy this than through Korg. Thomann will correct this for you.

You will know if its a problem because you will hear LFO cycles in your reverb. AFAIK, it was only the 220/240 units affected by the LFO noise issue. So there is a chance yours might have it...

If you do send it back, make sure they are aware that you are aware of this issue and demand it to be checked and fixed.

Otherwise you'll have to do it all over again when you get it back.

thanks for the info
it seems to be the case - I'm waiting for a reply from Thomann

I think saying ‘many’ have arrived broken is a bit of an overstatement, I’ve read most of this thread and the previous one and it’s been mostly happy customers with a few unlucky ones.

I’d hope Korg are working with dealers to properly sort any issues and look after customers, just as you’d expect with any new purchase.

I read it on another forum (not GS). Seems to happen in shipping. Moog had the same problem with the first batch of Grandmother.....

I’ve seen you post that exact sentence so many times in ‘many’ threads, at this point it’s smelling a bit whiffy.

If you want to be constructive rather than just spreading misinformation then you need to say more than just ‘read it on another forum’.

And what the f has this thread got to do with Moog.

a) I've posted it here (in response to someone having spring problems) and in exactly one other thread dedicated to spring problems in the 2600 - that's it.

b) I am intentionally not linking to a competing forum, that is just bad form. It rhymes with "duffpiggler", and you are free to look up the information on your own. It also has been reported by at least 5 people on this very thread.

c) Because it happened with Moog too - it obviously can be a problem with shipping a spring tank inside a synth, and is not just a Korg problem.


Iser has a problem, I gave him some relevant information which seems to have bore out. Not sure why this has you so agitated. This kind of information sharing is the point of forums like this. Take a breath and relax.

Can you post a diagram of a patch that exhibits the issue? Perhaps a picture of the front panel settings?

If so, I can attempt to replicate the issue.

Let's try this....

Get a basic sound going first....do whatever you want.


In your ADSR envelope set all sliders to 0.
In your AR envelope set Attack to 0, Release to 100%

Then in your VCA section set...
VCF - 100%
AR - 100%
ADSR - 0%

Are you hearing the ADSR envelope or the AR envelope?

Do you get any sound at all?

If not try changing the AR. Then try changing the ADSR.

Let me know the results...

I was mucking about and my adsr envelope wasn’t working, but then I made a patch in the book it was fine....in my end, definitely probably user error.
