Author SSF OCTOPEDE - DIY interest?
analogPedagog
Working on a DIY module called Octopede.

Featuring:

2 VCOs (LFO mode switch)
2 VC Slope generators w/ VC trigger delay and independent rise/fall shaping
1 dual peak SVF (series or parallel routing)
2 waveform mixers for routing into the filter
1 discrete transistor VCA
1 VC analog distortion with 3 distortion types
1 VC CV/trigger sequencer

This was going to be a full build with through hole components but real-estate is quite tight even with two boards.

Wanted to gauge interest in a partial diy build. Board will come fully populated with smd components. Optional mods, pots/jacks/switches will be DIY assembly.

Will provide panels and a dxf for custom panel designs

Below is a preliminary visual of the module and is not final.

50hp

Please comment if you are interested.

yay for smds! panel also looks fun!

hate to ask that, but any hints on the possible price range?
say to compare to Pittsburgh SV-1 / Mother-32

Full kit will probably cost around $350-$375.

double yay! i'm 90% in, just need to budget ahead of the release and listen to some demoes :-)

looks fun, i'm in.

Get tae fuck that looks rare fun

Interested, though I have to admit I have trouble telling what is going on from the panel. hihi

Yeah I'd be into building one of these for sure. SlayerBadger!

Would be cool if there was a PCB only or PCB/Panel option.

+1, PCB only preferred

I have a thing for (or more accurately, an embarrassing backlog of) small self contained analog synths like this. So yea I'd go for this.

Are these original and unique designs?
What makes them unique?

Yes, this is an original design.

I would say the unique qualities of the sound come from the filter voicing and distortion circuits.
The layout/configuration of the design is original and unique.
VCOs are pretty standard saw cores with edge and center pwm.
Sequencer is rather simple, using a johnson counter and features gate out per step and sequential trigger outs. Clock is a VC analog oscillator.
The envelopes are comparable to a DUSG but are not clones of that design. VC trigger delays to time delay the envelopes.
VCA is a dicrete transistor design that saturates well. There are two other distortion modes (besides soft saturation). They utilize some simple diode circuits to mangle the waveforms.
The filter is two SVFs using a pair of LM13700s and can be routed in parallel or serial. Spread offsets the secondary filter frequency.
Really just a fun combination of circuits.

Can do that option. Would be 0603 and some larger passives. TSSOP and similar pitch packages if you are comfortable with that.

That's great !!! hyper

Don't know how to finance this yet but it looks amazing and i could never resist here. Would prefer it pcb only without smt soldered in and then do a banana build.
sduck
I have absolutely no use for this so count me in!

Count me in

Would prefer just a PCB

Can the slope generators function as audio oscillators?
frozenkore
I'm interested in pcb/panel; looks fun.
elcoco
I'd be very interested in a set. smile

Interested thumbs up

Yes, will at least go a bit above 1kHz. Will give you more accurate numbers once I test the proto.

+1 love me some diy synth voice
