TB-303 patch

    Jun 07 2009 | 11:06 pm
    i'm looking to recreate a TB-303 in max, more so the pitch envelope, since i am a sucker for the squelchy sounds. Anyone want to point me in a direction? Here is a video link of that lovely sound around 1min 50seconds into it:
    Just to point out, i am not looking to recreate a techno sound, i just love that squelchy sound, wanna take it outside the box.
    Thanks! -chuck

      the pitch envelope in a 303?

      oops, perhaps its called "cut off frequency" or is it the "envelope mod" that makes that squelchy sound.

      so here is my feeble attempt, minus the squelch

      humh ... do you mean the glissando/portamento? glide knob + retrig switch?
      in max that can be very simple; you´d just trigger only the frequency with a new note, i.e. without triggering a new envelope, and insert a line~ / slide~ / or whatever to interpolate.
      the rest is to be done on the data layer, where you deal with the "note in" part of your "oscillator".
      in my (midificated) 303 hardware(s) this is done by overlapping 2 or more notes (in cubase): if you hold C while G is already starting, the 303 glides to G (exactly in the same manner than it would when you set a note to "glide on" in the 303s built-in sequencer.

      Roman, Thanks for the advice, i'm not sure how to implement it in the patch i supplied. If you have a second, could you show me? Thanks! -chuck

      so, here is the "squelchy" i promised.
      (i guess thats a british word?)
      how to trigger notes in 3 ways:
      - with glissando - without glissando - with glissando but in "retrig" mode 303 style
      instead of they keyboardsliders you can just use a [gate 3] or 3 different inlets for the patcher to send different types of notes from a sequencer.

      Roman, Thanks for the attempt but it is actually not what i am looking for. Perhaps my lack of description is the cause of confusion, here is the exact sound i would like to recreate live:
      The "squelchy" sound comes in about 30 seconds into this sample. Just to reiterate, i don't want to use samples, i want to be able to control a synth the produces this squelchy sound.
      One small favor to ask (for you and anyone who may want to step up to the challenge), could you not send it as a runtime? i wanna be able to open it up and tweak it.
      Thanks again! -chuck

      Roman, OOPS!!! i owe you an apology, apparently i was being an idiot and opened the patch in runtime....i'm playing around with it now, has some cool sounds to be implemented, so it is definitely useful for me in the future for some synth sounds, just not giving me the TB-303 thing i am looking for. Sorry for any headaches! -chuck

      the effect of this sound example consists of three things on the oginal 303: the glissando setting, the filter envelope setting, and definetly around 70% of "accent".
      to build a certain sound of a certain original hardware is nothing what you can do with a dozen of objects.
      that is a bit like with the original 303: it really makes a big difference who is turning the knobs. there is no squelchy preset.
      the "accent" alone would involve some hours of research about the original components and about how to build such things in maxmsp - [overdrive~] will not do.
      the VCF on a 303 is not just a linear fade, the tri oscillator is not just a triangle wave .. you get the idea.
      well, let me put it like this ... if you want to recreate an original, you need to recreate all of its parts, and each of them as exactly as possible.
      i would say you will have to spend at least 8 weeks in maxmsp until you get something which is ... similar.
      p.s. did you know that you can get a factory refurbished tb 303 with replacement knobs and built-in midi interface for under USD 1000 today? when it is really about the sound, get a real one, or better two. many cool things you have heard with it somewhere, was two of them.

      Roman, Thanks once again for shedding light upon the subject. i was wondering if i was hearing two oscillators going at it. The TB-303 itself is a wonderful instrument, if my infatuation persists, perhaps i will look into obtaining one. For now i remain thinking "in the box", treating my computer as a repellent for gear consumption (unlike my early days). No need to worry though, i always knew that the magick relies on the musician not the machine. -chuck

      In addition there is a lot of reverb involved as well. I would not recreate the original, but create some analog like synth patch with heavy filter sweeps and tweaks, plus reverb, and simply play around with it. Because that specific squelchy sound is known so well already, and if you just play for yourself with those ingrediences, you might come up with something more original. Advantage, it wont take you 8 weeks (maybe 6), disadvantage you will play with it much longer (maybe 26 weeks)...

      lots of info on it here:
      i guess that part with the "squelch" you are talking about might be a distortion pedal. The best 303 plugins (audiorealism's ABL and d-16 phosycon) have a distortion control which gets you these kinds of sounds.
      >the VCF on a 303 is not just a linear fade, the tri oscillator >is not just a triangle wave .. you get the idea.
      there's no triangle oscillator on the 303... saw and square

      oops ... well, the square sounds terrible anyway, it is only good for high pitched miau miou melody sounds. ;P

      Stefan, a synth with filter sweeps is exactly what i wanna do. Any good filter sweep patches out there worth sharing? i have tried hooking up an EQ patch to the patch i supplied earlier, but it just sounds like ass (or at least not the kind of ass i am looking for). i know max is all about the blood, sweat, and tears...i'm a lifer homies. -chuck

      scouring my mass amount of patches retrieved from the max list over the years, i came across this:
      but i don't know who is the author. It does however give off the sound i was basically looking for but it useless to me as it, but wanted to share it with the rest of the forum. i will probably take it apart to give more control to the user and less to the computer. -chuck

      So, someone has beat me to it, and have down a bang up job emulating the tb-303, enjoy:

      Thanx I was looking for that awesome patch.....
