SH-09 filter

[Nathan Balas]

Hello AH

I have a Korg MS-10 and an SH-101. I strongly prefer the MS-10 filter.
I love the wretched squelchiness. The SH-101's filter seem too even
and clean.

I like to turn the resonance up and the filter frequency about half
way down. Square wave, PWM half way up. And a bit of filter cutoff on
the envelope.

Is the filter on the SH-09 closer to the SH-101 or the MS10?

Thanks, Nathan

neither. but, for lack of better words, it is much much nicer n well..
fatter than  101's filter.

ive done a few SH-2 demos some time back, it is identical filter to SH-09..

thanks niall :)  its a fantastic little synth, one of the last ones that
hasnt sky-rocketed in price..


as for kss,  i just have limited time so i concentrated on AH and VSE in
last 2 yrs. cant run on
3 - 4 forums/lists..   but i was thinking of coming back, for a change, then
i'd leave VSE for a while ..

regards
Tom

I'd actually love to have one of these if anyone has one for sale at a fair price....

[Nathan Balas]

Yes, these are nice demos. And I hear what you mean. I'm sold

Thanks for the input

what's needed here is for someone to do a nice IR clone PCB. maybe
recycle all those 106 chips where just the VCA has blown. then
everyone can have an SH09 filter.

The sh-09 uses 4 BA662s for the filter I think, its very hard to read the
parts on the schematic but its not an IR3109.

The IR3109 is a pair of BA662s in 1 DIP package...

curetronics now make a clone pcb of the roland m121 vcf that is identical to the sh09 vcf

http://www.curetronic.com/curetrbau/neubau/100m.htm

unpopulated pcb 9 euros, complete trimmed pcb 55 euros

Although at that price, he will probably build his 6110-version.
I can't imagine he can do four 662's for 55 euros.

I built the 6110-version and even without calibration and with
unmatched FETs it sounds pretty nice, but I have no way of
comparing it to the 622-version.

[Oakley Sound-2]

The forthcoming Oakley Sound COTA VCF is aiming for a similar sound to
these classic Roland cascaded integrator filters. It'll have a few extra
goodies attached too. In either 1U or 2U MOTM/Oakley format.

The stripboard prototype has been tested, but the PCB prototype is not
with me until next week. Hopefully, Oakley Modular - not me - will be
able to release the board in a couple of months time.

I would expect ready made modules to be available through Krisp1 shortly
after.

are ba662s still in production?

i wouldn't want to consume rare stock to build one of these things.

sure it be nice if its the same, however, SH-09/2 with four BA662s filter
sounds VERY different from
synth models following (with the integrated IR3109 version).   so similairty
stays on paper spec,
sound reality is different.  and thank god for this variety.


IR3109 based filter, especilly circuits  in JP8/JU6/JU60 are equally
beautiful and liquid, in their own
right.    i would love if someone could figure out how to make a 12dB
IR3109-based module copying one from
JP8 schematic.. whoaaaa      is that possible at all?

If I understand correctly what you're asking its very easy, tap the main
output from pin 7 instead of pin 15. Leave the resonance path coming from
pin 15 though. It's late and I could be wrong.....
