Binary Game Sequencer

hi all,

this is what i finished last night. i am still missing the front panel, so the LEDs are not mounted yet...

it is a new kind of an unipolar sequencer, based on a binary counter/divider (4024), instead of a decade counter/divider (4017).

the concept: each divisions output is routed to an attenuator. the divisions attenuated voltages are then summed.

the realization: each divisions output controlls a CMOS switch. these switches have sockets on it's inputs, normalled to +V. so for each division you could use an external voltage also. this voltage is then going to a simple passive attenuator, and is then routed to one or none of the two CV mixers (on/off/on toggle switch).
additionally each division is converted to a trigger and available at a divider output socket.
a step and reset control makes it complete.

taking a look at the pictures below you see for each division from top to bottom: external voltage input, attenuator, routing switch, LED indicator, division trigger output. bottom row is for I/O (clock, reset, CV outputs A & B).

the nice thing is that you create two CV sequences that are related to each other.

schematics, demo and better pictures will follow as soon as i got the front panel... i just had to share.

Hey Matthias, that's really cool - so if I get this right, you can send each steps voltage to be summed at either A or B or off at the flick of a switch?

I was obviously somewhere else this morning! I get it better now, helped by the panels pic on Muff's, i think I was confused with the binary counting, I went somewhere else, actually seems better now I properly get it Laughing

so here is a 1st sample i did. no big deal, just the Binary game Sequencer, the doepfer quantizer, two thomas henry VCOs (555 and 4046) and my LPG. 1min of patching and it sounds like this:

Listened to this earlier today on my sound cloud subscriptions. Very pleasing to the ears. Had to check this sub forum to what it was all about. Cool idea!

Very nice Mathias! Cool

front panel arrived, LEDs mounted, all is working as expected :guinness:

last night i made a quick video. no time, no light, bad camera, bad vid quality... anyways, it shows the basic functionality and concept, i think.

quick and dirty demo of my new binary sequencer from fonitronik on Vimeo.

(each CV channel to a X4046 VCO. 1st division trigger out to LPG for 1st VCO, 2nd division out to 12db SVF - in the beginning only channel A, later on channel B fades in. switch set to left routes the CV to channel A, to the right channel B, center position OFF)

and here a few more demos (i am in love with this thing)

Wow...these are crazy good!

I hope these will be available as kits in the near future...

Hi Matthias

i'd be interested in pcb's if you are doing a run.

i will do a run, if there is enough interest.

i already did a re-design of the circuit board to match the eurorack front panel PCB. they could be mounted piggyback to avoid any manual wiring (however, i know that there are not that much eurorack lovers here, no?).

anyways, i will have to finish two other prototypes first (TH ADSR, and the new fonitronik triple vactrol resonator).

I'd be interested in a set of boards if you do a run. Particularly interested in it's ability to take external inputs, makes for some very interesting possibilities.

I was just watching those videos - this is a really nice design.
I think I could find a place in my system for such a beast if you decide to sell the PCBs.

i am really want to. and i decided to do a re-design making it bi-polar, with attenuverters and dgxxx series analog switches. you could then use it i.e. as an 7 channel attenuverting mixer with two summing busses. Twisted Evil

Hi Matthias

did you have success with the V2 design of this binary sequencer ?
I'am still very interested in this project Smile

I have got a few cd4024's laid aside ready Very Happy

Dave.

i am working on it, alas, it gives me some headaches, especially the eurorack front panel components PCB - i think i will still use ribbon cables for the interconnections...

anyways, the schematic is done, and the circuit board is done. the new features are:
bi-polar with attenuverters
a rotary encoder ISO a step switch: this way one can 'scroll' trough the steps. should be much faster than a step switch, all the more if you go through 128 steps to have all channles on for a 7 channel attenuverting mixer.

Glad to see this is still going. Been looking forward to this and was wondering how it was progressing.

Great , a probable xmas project ,i look forward to it Smile
