Low pulsing drones, dive bombs and high-pitched laser sounds! This drone monster has six square wave oscillators with a delay, essentially combining two 4093 NAND Synths and one Cosmic ECHO.
The Nandamonium has two SAG CV inputs. When the CV jack is patched and the switch is toggled to “CV,” the NAND circuit is powered directly by the incoming voltage. Beyond controlling pitch, the incoming CV can also be used to create lofi rhythmic effects.
Dial in your drone with the Nandamonium!
Features:
- Six tunable square wave oscillators and two level controls
- Delay rate, mix, and feedback controls, with touch control over the rate and mix
- Warp switch: adds a bright, “small” speaker tone
- Blast switch: introduces max feedback into the circuit momentarily, great for adding rhythm and strange sounds
- Two SAG CV inputs, one per NAND synth
- CV/On Switch allows selection of CV control or internal power control (1 switch per NAND synth)
- 3.5mm jacks
- Requires a 9V center-negative power supply or 9V battery (not included)
I need this. How do I buy it?
You can purchase it on the synthrotek store, here:Nandamonim
Will you ever be selling the pcb for this?
Hi,
Just got this while visiting Berlin. Really dig the sounds one can get from it.
Just a question bout CV’s. I tried to feed gate and oct/V signal with a plug into CV port but it machine only reacted on signal coming from the tip.
Is it possible to feed to different signals through one plug (both oct and gate) or is it possible to add more audio jacks for CV gate.
BR.,
Heikki
Hey There,
The Nandamonium is only capable of taking the CV inputs through the tip of the jack, as the sleeve connection goes straight to ground. We haven’t messed around with modding it to take more either, though I’m sure it is probably possible. If you figure anything out, feel free to post it up here.
Best,
-Patrick
What is the CV voltage range input for the Nandamonium?
to stay on the safe side, I would limit cv input to 0-5v.
Best Regards,

Can I buy labels to mark out the Nandamonium’s controls from Synthrotek or do I have to print my own?
Hey Alex,
We do not sell labels for the Nandamonium. If you bought our completed version you would get the artwork and enclosure.
As a kit it is left up to you to label it however you would like!

Ok, I’ll be creative!
Cheers,
Alex
Using the CV ins and coming from a keyboard with pitch cv out, can this be played as a mono synth rather than drone?
Hello John,
The CV input is not 1V per octave so using a keyboard would be fun but not what you’d expect from a 1V per octave module.

Hello,
this thing is fun! but I’m not sure if my build is totally working ‘correctly’: are both LED’s always supposed to be ON when the power switch is on? (that’s how this one is working). And is the CV switch action correct?: I only get sound in the CV ON position; when switched off sound trails off with an upward pitch. Thank you!

Hey Steve,
This does sound like a strange issue.
Would you be able to send a video of what you’re experiencing to store@synthrotek.com.
Seeing the issue for myself should hopefully allow me to isolate the issue.

Can this be connected via routing in between some place on the pedal of a guitar distortion pedal like the metal zone from boss
I was wondering if I could connect my guitar as usuall and have this connected as well for sound altering
You could boost your guitar with a preamp and put that into the CV input, but I cannot guarantee that this will not hurt the unit.
