And it can be that we need to wait several years before they release a new model. I still regret not buying the Korg MS20 FS that they sold a few years ago.

did you ever try running it through external speakers?
Can you power the arturia keyboard with the Arp?

I want a FS version of the ARP 2600 for my studio and MS20 but need to wait a while. Maybe in a year or two. I have gut feeling Korg will update it as it is so popular seller.
I havenāt had any trouble powering the KS37 with my 2600m. However, before replying I powered up my 2600m and the SQ-64, and the SQ-64 booted and ran just fine from the USB, as did the KS37. Korg has assured me that the 2600m canāt power the SQ-64, so take this all with a grain of salt.

Yes I can, it works flawless! Thatās a really nice feature on the M.
Short term or long term ? There is a difference, heat disapation, in particular. That is also affected by ambient temp.
I was thrown reading about quietly destroying the USB ports on Sequential gear attached to powered USB hubs. Very different from what you are doing though. Still surprising.
Korg didnāt say. My experience is that sometimes the SQ-64 will power on just fine, but most of the time it will fail part way through the boot process, if it is being powered by the 2600m.
As far as temperatures go, my HVAC is set to 75F, but there is a pretty significant temperature drop close to the window where my gear sits.
That raises another point, peak vs nominal. There are a bunch of more questions behind this. I think the 2600 is sending you a message. Itās up to you whether you listen.

Iāve been running it with a separate 9v power supply to keep things happy, but wanted to confirm that the SQ-64 still fails to boot before assuring anyone that the 2600m can successfully power the Keystep. Since the SQ-64 booted it is unclear how safe it is to run the KS37 from the 2600m.
You have an oscilloscope donāt you. A nice long interval digital scope, ( or with the right trigger ) with it set up to measure current, and you could watch what happens when the SQ-64 crashes. Thatās what a nerd engineer might do. Same for the KS37.
ADDED : They could be drawing the same amount of current, the difference being the processor in the KS37 being more resistant to brown out.
The engineers at KORG probably want something like a factor of two margin for the real power draw. So there could be a small margin between.

was pretty impressed with this one (especially the HPF trick):
That does look like a fun combo, and is a great confirmation that they are pretty close to the same size. KARP is wider, B is taller, but only by a little.
Yes, it really is! The limitations that you have to use one of the oscillators as an LFO is gone. I did a patch last night where I used all 6 oscillators. It sounded amazing! 
I did a quick comparison of the square and saw waveforms, and I canāt hear any difference at all. So I can really use B2600 oscillators with the ARPs oscillotors and it will sound as I am using one synth but with all the possibilities that two 2600 gives.
I have now compared the sound and shape of the oscillators of the Arp 2600M and Behringer 2600 by ear and with an oscilloscope and the square and saw waveforms are completely identical on my machines.
The triangle on the Arp has more harmonics and sound more squarish compared to the triangle on the B2600.
The sine on the Arp are close to be a clean sine while it has more harmonics on the B2600 with more of a square shape.

More fun and educational than your average synth versus vid

seeing as weāre doing Behringer/2600M crossover - iāve found the Edge is a great source of modulation, clocks and triggers for my 2600M. with a bit of creativity you can get various LFO shapes out of it
