Roland System 100m

Hello,

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
