Thomas Henry's SN76477 Super Controller Module

hi all,
there was a lot of talk about the SN76477 lately and there are a lots these ICs waiting for salvation, i guess.

i got thomas henry's permission to do a PCB run for his Super Controller design, published in "polyphony" and his book "build a better music synthesizer" (many thanks to our broadminded mr henry!).

boards are now available. the PCBoards size is 4.65x3.1in (118x79mm) and provides +5V onboard source and MTA.100 connectors for almost all switches, potentiometers & sockets. it will take both wide and narrow body ICs.
all who placed an advance-order will have received a PM now. if you changed your mind PM me to cancel your advance-order, please!

EDIT: documentation uploaded. hope that's sufficient. if not, comment please.

prices:
PCB 18.-USD/13EUR each
1x S&H 7.-USD worldwide/3EUR europe

SOLD OUT

It utilizes the SN76477 to build a versatile CV source unit:
one gated/delayed LFO (with hold function!) providing triangle and square, trigger and gate outputs.
one noise source with selectable frequency range and sweep
one sample & hold with portamento and attenuation

a great companion to the SN76477 Voice!?

short description:

there is the LFO section to the left. you will choose mode of operation with a switch selecting delay, gate or switch. in delay mode the LFO will start when triggered depending on the delay time - so you can create delayed modulation. in gate mode the lfo is alway on until you plug a cord in (switching jack socket). from now on the LFO is on when a gate signal is present. in switch mode you can perform a "hold". the LFO stops as soon as you close the connected (foot?)switch. a status LED above the mode selector indicates the LFO working. there is a selector for the LFO range, a rate control and a LED indicating the speed of the LFO. there are four outputs: triangle and square wave, the gate and the trigger outputs a derived from the LFO. the gate is derived from the square wave output but going from 0V to approx 10V (or whatever, depending on a resistor value). the trigger is derived from the triangle and delivers a 1ms pulse. don't forget: the output is gateable or controlled by delay or switch!

the S/H section in the middle: the S/H is clocked from the LFO trigger and provides a portamento (lag) and depth control.

the noise section is to the right: the frequency range of the noise source is selectable by a switch. furthermore there is a filter control (known from the SN voice) and a attenuated cv in for the sweep, which base is set by the initial control. you can select external or internal (LFO) sweep modulation.

hope i got it right.

I got a copy of that book 2 weeks ago and was thinking a Super Controller would make a nice addition to the modular
put me down for 2 Smile

I'm interested in one

Yup, one for me! Cheers!

OMG!!!!

Another board?!?!?

Will someone do a board for the Paia Ribbon controller? They seem to have 'dropped' that project Evil or Very Mad

I suppose I should say YES, but I've still got to pay for the last one Embarassed

Can't say I'm not interested, but my sole SN is taking up residence in me SN-voice. Also I have only heard about the supercontroller, never having seen the documentation for it. Posting it here or anywhere is out of the question, but maybe a panel mock-up could display the general idea, beyond Fonik's description. Just 2 cents in the pot...

I wouldn't mind seeing the Supercontroller mk2- which doesn't contain an SN Question

Sure, I will take 2 for myself !!

Thanks !!!

I'm interested!

Can you design with something other than the 4136? I loved your resonator board, but wonder if there could be wider cap spacing to fit little AVX box caps.

No big deal as 4136's are still around and I have a variety of caps. Just a thought...

Edit- Something onboard to regulate +5vdc off the +15 rail would be cool.

I'd consider 2 boards.

Wow, Thomas Henry's SN76477 frenzy continues!

Please do put me down for two PCBs.

A couple of suggestions - pads for both the regular DIP and shrink-DIP versions of the 76477 would be very helpful, most of only have one or the other. Also, replacing the 4136 with an op amp using a more standard TL074 type pinout would help most people out.

Huge respect and gratitude to Thomas and Matthias!
