my first 303 clone

Post by guest » Tue Jan 12, 2021 8:15 pm

ive had a lot of time on my hands lately, and decided to scan in a bunch of old slides. one of them had my very first diy synth project on it, a 303 clone. im sure thats not a super suprise to anyone. and it sounded nothing like a 303. all i had to go on was some schematics i pulled off of hyperreal.org.

Image

it was just the VCF, and barely that. i swapped out the output stage with opamp diffamps, and im not sure what i was using for current control, as there arent enough transistors on there for the expo setup the 303 uses. i rolled my own VCO, VCA, and ADSR. i had a variable length gate i could produce at a variable tempo. all modifications were made with a precision screwdriver on the tiny trimpots on the board. i made my first electronic music piece with it using 2 tape decks and overdubbing.

at the very end you can hear a drop bass networks track start to mix in, and that was the initial inspiration for the piece, but it sounded nothing like it, really. but looking back, im glad about that, and that the tempos of the overlayed tracks phase in and out with one another as it seems a bit more interesting.

i wish i had a photo of the rev that came after this one. i built it into a two octave fisher price keyboard with speaker, and put some gold and silver knobs on it from amercian science and surplus. the entire top was nothing but knobs and switches, and it had an arpeggiator and random sequence generator with variable "randomness". it was a more faithful recreation of the original 303 and sounded much better. i used it a fair bit on the metropolis soundtrack i did a few years later.

thanks all! im really horrible when it comes to documentation. id love to be able to see a schematic for that thing so i could shake my head in dispair. ive come a long way. heres the metropolis:



the really watery acid in the beginning is the interim 303. its that pesky filter warble to a super extreme. i tweaked it to enhance the warble.

[EDIT] its mostly remixed records. i was djing for a number of years before i got into synths as i felt sort of limited by the records.

Love it. So is that 303_98 as in 1998? You've been at this a hot minute eh?!! (Label me completely not shocked at that fact if it is true due to your depth of knowledge!) :sb:

i borrowed my first copy of horowitz and hill in 98, and pretended i knew electronics for a number of years afterwards. i feel like i didnt really get decent till the x0xb0x project circa 2005. and even then, i look back on those days and wonder "what was i thinking??". but i take that as a good thing. the moment i cant look back and think that, is the moment ive stopped learning. and there is always more to learn.

H&H is not very good for learning electronics at a beginner level i've found out... so many elementary important concepts that are simply glossed over!! more of a handbook for real engineers.

ha!! thats amazing, and so appropriate! thanks for sharing.

as for the tracklist, i will see what i can put together. i used to have a tracklist with all the transitions listed, but tossed it out years ago. at some points its four layers deep. i had 3 turntables, a synth, effects and tape loops.

It is the ancestor of the x0xb0x. I think the x0xb0x has changed the life of many people. Ah, ah, 303 subscribers, you don't have to subscribe anymore.

Ahh, the Adafruit x0xb0x kit waiting list was the stuff of legend :lol:

Im not half as clever as guest, so my first 303 clone was a Control Synthesis Deep Bass Nine (not DIY). I still have it and it still works pretty good (could do with new pots). Its far from the best 303 clone (even calling it a 'clone' is a bit of a stretch really). It has no sequencer for a start. But it's wicked as a somewhat acidic bass synth, with far more low end than an original stock TB-303 has.
I also just realised that it is 27 years old. Practically an antique classic in itself now :hihi: The original TB-303 will be 40 next year!
