Korg Arp Odyssey ADSR mod

[artilect99]

Hi all,
I recently heard about a certain "turbo" mod for the original Arp Oddy ADSR. This mod added a 3-way range switch to achieve shorter and longer envelope times on the ADSR gen.

I am curious about implementing this on my KARP, whose ADSR I find to be a little flabby on the minimum attack/decay times. I think I found the relevant timing cap, circled in the image below (I'm an EE layman so hold the laughter if I'm totally off base

Does this look like the timing cap for this circuit? It's all SMD on the kARP, so prior to implementing a range switch I'm thinking of just swapping out the electro for a smaller value (~2n2 - 1uF) to see if I can get more precise adjustment of shorter envelopes.

Thanks for any help!

PS -- would this be the timing cap in the LFO circuit?
