That's what I make from it as well and it makes sense to use those. Edit : 1N914 it should be.

The other wire(s) would be the ground wire(s), it's not unusual to not draw it(those) in schematics. _________________ Jan

As long as it's fed from the same supply that should be no problem. The counter chip wouldn't like the clock to go higher than it's supply voltage. _________________ Jan

Good you got it working
The dot in the red square makes no sense indeed.
The ground connections for the pots should be pressent though. When they are not the CV ouput voltage is not well defined and depends on the load connected to the CV output. Well it does so anyway with 100 k pots and no buffering I guess, but it will do even more so without the ground connections.
To make it better a fixed load with a buffer opamp could be added maybe.
I'd put in the ground connections and then see if any weird things would happen for the purpose in mind, and if so, then add a buffer thing. _________________ Jan

I'm starting to build it today... I saw that this topic is too old, but I would like to know if there is more to know about the schematic I found at: midiwall.com
Thank you all very much! |

thank you!
I would like to know if i can hook up the end of the 4017's exits to a deepswitch, and after to the reset pin. I would like to have 8 step reset switch. Is it possible to do? |

Do you mean you want ony 8 steps? If so, you van connect the output (step) 9 from the 4017 to the reset pin of the 4017, so it starts again. You can add a rotary switch to select the steps you want to play. (Switch which step connected to the reset). No so good at explaining but its really simple. |

thank you guys! I did it! It works!
only one strange thing... when I try to play, for example, only 4 steps, i hear: 1. 2. 3. 4 and then 2 or 3 beats out of the sequence!
I linked 4017's pin 15 with 9, and first to eight channel to pin 15 through a deepswitch.
Where's the error? |

can the baby 10 run off of a 9 volt battery?
Any special tweaking needed to do so? |

I'm not really expert... but I think you can keep it running until a 15v battery.
So... I've another question: If I would like to build more baby 10 with the same clock, which of the following way can I try?
1 - I can build 3 separate Baby 10 (for example) and one clock generator (555) that leads all sequencers.
2 - I build a sequancer with 10 steps, and then, if I would like to have another, I add 10 other steps at the same 4017's exits... and so on... I mean something like casper electronics sequencer, it has 8 steps and 4 channels |

i would prolly go about it by way of method 1.
But they will all step at the same time, not in sequence (you cant get a 30 step sequencer from chaining 3 baby10s together this way) I think you could just split the clock signal into 3 separate 4017, prolly use a diode there to keep things from getting weird. Or split the clock signal with a 'reverse mixer' op amp schematic to prevent the clock signal from breaking down as you split it.
Im in San francisco, im not sure where to get a 15volt battery, unless I chained a large amount of AA's together.
I have a new project im working on, a kind of semi mini modular with the baby 10 involved, every thing is running off of 9volts... just wanted to know if i could either use the baby10 off a 9 volt battery or just power everything off a 9volt power supply. |

my baby10 seems to make the same pitch on every beat (i am feeding it a 40106 clock and outputting the summed/dioded CV to a 40106 YAVCO).. are the pots supposed to control the pitch or just how much of that beat is in the signal (volume)? _________________ http://www.soundclick.com/amplex |

I had to read this a couple of times, sorry. I still don't understand what the question is. The pots are supposed to output varying control voltages and your VCO should change pitch relative to those voltages. Is your problem that the pots don't work? If the LEDs light, you should have some voltage present... are you getting gate out? What voltage are you driving your baby10 with?
I guess I don't understand what it is you are hearing. "beats"?
Are the diodes in the right way, just wondering. _________________ Garret: It's so retro.

Nandsynth + Baby8 = 'NB8' |
|
|
well i got this idea from researching a few nand gate synths and a few baby10 sequencer schematics, and came up with the NB8 or NandBaby8, very similar to the SGMK nandsynth/sequencer, but changed in a few ways.. No schematics as of yet but its basically a bolt style patchable Baby10 permanately set to 8 or less steps (with reset in). I used a 4017 for the seq, 40106 for the int clock, 4093 for the nands, and an lm386 for amp/gain, all powered off a single 9v, and packed into a nice 4x7x4" stylish florescent green box. The controls are:
top:
8 steps on top (round 100k pots)
2 nand freq's (in the middle)
2 nand 'mixer' pots (the outside ones)
front:
8 red leds in the middle for which step sequencer is on
1 amber power led on left
main mixer pot between left and right nand controls (backwards doh, too lazy to fix =)
2 fixed LP/HP on/off for both nand channels (these do strange things to the sequencer so i dont use them much)
right side:
spdt switch on right to select which nand gate gets the sequencer cv out (both on one side of the switch, wired straight into the pots)
sequencer speed pot on right
left side:
on/off switch
int/ext clock switch (bolt on back for ext clock)
pot for pre gain/feedback on lm386
(hole where i was going to put a glide switch but didn't include yet)
back:
1/4" out
each sequencer step pulse out
sequencer summed cv out
clock out (int clock)
clock in (ext clock)
seq reset in
ground
(audio out bolt to be added soon, again too lazy to include so far)
so far the only major problems have been the fact that i used varying resistors on the leds because i didnt have enough low ohm ones (around 500) to work with these (i think) 12v leds.. but it made for an interesting sequencer pattern multiplier at least =] also the nand 'mix' pots have way too big a range, but its quick to turn them off and on this way. also i would use a rotary switch next time to allow for some more interesting combinations of where the sequencer interfaces with the nandsynth. right now its 1) middle lug of left nand 'mix' pot or 2) right lug of right nand freq pot (which barely affects sound). also the controls of the nand synth do strange things to the sequencer like slight speedups and slowdowns. this is undesirable, but the sound is affected in a very desireable way imo!! i've been recording and editing long sessions and cutting some samples for use in new tunes but havent got around to starting the tunes yet, going to document some of my work today and upload some video to youtube of a few things seperately and then together =] big huge thanks to dusjagr @ SGMK for the awesome idea, and as usual everyone on here for their helpful replies & entertainments _________________ http://www.soundclick.com/amplex |

Sorry, haven't come back and let everyone know I figured it out, it was a problem with wiring on the pots, wasnt sure which one the wiper was, got it figured out on breadboard last week, but then by the time I soldered everything in together in the NB8, it is back to doing the same thing (due to how I routed the summed CVs into the nand synth.. oh well, the CV out still makes different pitches fine on a VCO, just all the pots are upside down.. noob mistake!) but its all for noise toys so it doesnt really matter, when you play with the thing you figure out what it does like a puzzle kind of the thing is powered with 9v, the led resistors make their own sequence (varying from 560 to 670 ohms, accidently used 12v leds)

'Beat' = step of the sequence.. sorry thought the context made sense but.. i am known for choosing words badly much of the time

(or else just negative voltages blocked from exiting sum of step pots) .. hrm wonder how this would affect the CV out signal or if it would work @ all.. _________________ http://www.soundclick.com/amplex Last edited by amplex on Sat May 30, 2009 3:36 pm; edited 1 time in total |

15 minutes of noize (NB8->VCO->AX30G efx proc) |
|
|
ok i got a huge 15min mix of the sequencer going to my lunetta, and then effected by a korg ax30g guitar processor (some rev/delay/eq), just going to include a link to the whole thing for now (warning: 25 megs or so) .. there are some blatant cuts removing more uninteresting parts, and fades here and there where i first was cutting things. pretty inconsistant, aren't i? thank you coffee
the first couple minutes are going through interesting presets on the ax30g that i made, the rest is all nb8 manipulation on a preset which is basically reverb/delay/eq.. cool rhythmic sounds/glitches all coming from the sequencer.. starts getting cool around 2:10 or so imo, some boringness around 10minutes, then @ 10:38, really cool sound to sample, kinda like a trumpet or something! then around 11:00 we get to the cream of the crop as far as im concerned, pretty sequence with electrobugs in the background =]]
15 minutes of noize

clock changes based on nandsynth controls .. |
|
|
wish i could have fixed the sequencer part of it so the clock never wavers or changes based on whats happening with the rest of it, only (easy) way i can think that might fix that is run the 40106 off a seperate power/ground (another 9v or something)..
heres another quick (3min) sequence that starts where the other one left off, much shorter, same setup, nb8->yavco->ax30g
Take 2.. same setup, more noise, 3minutes, 5megs _________________ http://www.soundclick.com/amplex |
