Thanks.
Yes, I looked at the VCO circuit, and electrically it's just a matter of bringing out one jack per output. I don't want to damage the current modules with the mods, so I was thinking of external jacks like you mentioned. Something like the separate blocks of jacks in the old Technosaurus modular.
There is a good page about the 112 VCO here
so now i know how to disassemble it to do the mod. I'm a Yahoo group newbie, but i think we should post this link along with the other mods.
Nice monster system, by the way. I saw it at sys100m.org.

I did the "sem-mod" on that m-121 you mentioned, but It was not really a "mod" to the original
cirquitry, the whole vcf pcb was replaced with a clone of a dual sem type svf
when it comes to separate outputs for the different waveforms on the vco´s, electronically
it would be very simple, unfortunately there is not much panelspace to have room for the
extra outputs, at least if you want it to look good, maybe an alternative would be to lead the
waveforms out of the module and use a piece of the 191j´s upper row of multiple jacks in some way.....

Subject: [RolandSystem100m] filter mods; multiple outputs on VCOsHello,
I just joined the forum, and immediately found the 121 HP VCF mod. Nice.
There are two mods I would really like for my 100m:
1) switchable modes for the filters (not just LP or HP). Someone on
Matrixsynth mentioned that this was possible, in reply to the posting
about the SEM-filter-in-121-box mod.
2) simultaneous waveform outputs on the 112 VCOs. Having only one
waveform at a time per VCO is annoying.
Has anyone done these mods?
Thanks,
Peter
