Atari Punk Keyboard

[rikardoss]

friend, as you could do the bent to the effect on the keys with the ataripunk?? tutorial or something plz!

really nice job!!

[MarioWars]

I found it! Its the MK-373D!

[MarioWars]

holy crap

need tutorial

[1787dude]

i think i could do that, u made it look easy,

[thesk8rman765]

I'm thinking about making an ATC synth, much like this one, except with a slider instead of a pot for the first pitch shift knob, and will throw in a low and high pass filter, and a diode clipping distortion maybe.

How old is the keyboard you made this with? I want to know how far back I'll have to look into keyboards to find one that has resistors on each key, and not a contact that runs into a digital IC. >.>

Do want

[pencildives]

What do you mean by the hz part?

[higuything21]

JOHNY! STOP FARTING!

[snower5554]

where do you get the knobs and switches?

[y0utub35uck]

it sound SICK

i like it ))

[sammywombarra]

so im guessing this is a resistor based synth, so i could, in theory, replace one pot and wire in the resistance part of the keyboard and that would work...right?

@sammywombarra

That is how the old voltage control keyboard controllers for modular analogue synths were made. Most actually had a standard of 1 volt per octave so you created a 12 step voltage divider (12 resistors of equal value) between each octave on the keyboard. The keys each key in the octave connects to one of the resisters. The higher up the resistor, the higher the voltage, the higher the frequency of the oscillator.

[sammywombarra]

indeed i knew that.

as i understand this is very similar to how the APC works (just less complex). the variable resistor has replaced the keyboard because they are difficult to make. so my tasty £4 keyboard should be fitting for the keyboard control aspect of it (obviously it won't be in tune, just more precise). unless i'm completely overlooking something here.

[strings723]

Can I have it?

[manufacturedZ3R0]

Real nice work on this one. I often add apc's to my gear to turn them into twin/three oscilator hardcore machines but have never tried hooking up a keyboard to control one. Really cool results you got there.

[dejodenzijnboos]

k, I have a keyboard like this?

how to start making this?

help please!

[geboy5]

I have a toy keyboard. how do mod?pots,...

[xhaylowx]

you circuit bend it, open it up, only if it's battery powered, use your fingers to find bends, like the pitch bend.

[theglurgle]

So you've read all about it? Haha, actually TRY something before you start reciting websites.

[xhaylowx]

i have TRIED it.

xD

i have a circuit bent keyboard from cvs. and a few other toys.

[shnitzelguitar]

does the second switch control the second pot??

[shnitzelguitar]

so do you think that if i wired a guitar to one of the pots i could use it as an effect??

[larsby]

you could, but it wouldent sound the same

[shnitzelguitar]

what do you mean by that??

[chaffel3]

a guitar doesn't really have a varying voltage like a synth, it has a frequency which makes it hard to process its pitch

[gushhnet]

if only you could play the keyboard...

[01928378]

that´s really awesome. Good work.

[virus616]

that's nice. Especially the way you incorporated it into a keyboard

[samboothey]

haha this is awesome.

i wanna do this. xD

[AlbinoPiglet]

I'd really appreciate it if you wrote somewhere how exactly you wired the keyboard. Because I am very interested in building one myself!:)

[larsby]

there is a resistor on every tangent. so I just wired that whole array into the hz part of the APC.

[AlbinoPiglet]

I see but I meant like a close up picture?

[bootyproducer]

sick. build me one. the keyboard touch really manes it the ill na na.

[IrishRnB]

So how'd you wire the keys? Does the voltage vary out from the matrix?

[larsby]

normally there is a pot for the tones

[IrishRnB]

So you replaced the pot with the varying voltage from the key's matrix? I am i understanding that correctly?

[larsby]

exactly

[IrishRnB]

Sweet! Not only is that a great idea, you executed it really well too. Nice project, man.

[sonorosapiens]

Respect

[afodis]

Funny I found exactly same keyboard and was thinking about doing the same thing. Now I see it'll work quiet good. Thanks for posting.

Horribly made keyboard but good for this stuff :-)

[burri123]

Incredible!!!
