Re: my first 303 clone

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.

Re: KORG35 filter - voltage conversion and transistors

Other question, i still have 2 clones of korg 35 left. Nobody made a PCB to have a 35 filter, for modular? On which we could graft the korg 35 clones. Or a vero board? It doesn't exist? I searched on internet and saw only OTA clones...

Re: KORG35 filter - voltage conversion and transistors

Hi, i have an MS20 korg 35, KLM127, the auto-oscillating filter too much, it's bad for the synthesizer play. It has an abnormal behaviour, it's not much, but i find it annoying ... I compared against 2 other MS20 equipped with Korg 35, here is OK... Mine itsn't OK. I replaced the Korg 35 by DIY clon...

Re: MB909 alias TNINER alias TR9090

Hi Alain, i remember well your MB606 on the anafrog forum. My bug first appeared about a year ago and worked fine for 6 months after that. For the last few months the problem has persisted. It's possible that a cherry swich is messing up, i hope that's it. But if i remember correctly it is not alway...

Re: MB909 alias TNINER alias TR9090

Everything works, except that it randomly changes the pattern on its own. It's like MB808 but more elaborate. It has nothing to do with nava, the only thing in common is the instruments, it's a much more powerful sequencer. MB909 can sequence several drum machines and synthesizers simultaneously. I'...

Re: Mouser is great but i hate it !

Mouser is a professional site, often a little expensive, but with a lot of choice. And above all the components are of high quality. The good thing about them is that they have a head office in my country, yet they are an American supplier, in case of problems with an order, i always have someone to...

MB909 alias TNINER alias TR9090

Hi, maybe you remember MB909 which had several names, it was introspectiv 9090 with a midibox sequencer which had an interface resembling the TR909. Mine worked well for several years, but it was difficult to get something that worked well, it took weeks of work, you can't count in hours. ;) Mine is...

Re: Where's knobs for 4mm shaft?

I am missing less than 10 knobs. I'm thinking of buying those from aliexpress as i can't find a better one. Sifam does too. The ideal would be shaft with the flat, not screwed.

Where's knobs for 4mm shaft?

Hi i've been searching for some knobs for PC16BU potentiometer: https://www.omeg.co.uk/wp-content/uploads/2020/02/PC16BU.pdf The problem is that it's a 4mm shaft, it's not common.

Re: dead TT303 v1

You should buy the RE-303 PCBs, with a bit of dremel the case will fit, you also have the knobz you can get. That's a good excuse to build a RE-303.

Since the time has passed and i've made something different out of it. I removed the fuzz but installed a monotron VCF on the master output instead. And i added pitch and drive mods on the toms. But i've built one for myself and i won't build another. Because i think it's pretty risky to try to make...

Wouldn't your switch be a momentary one? Or a faulty on/on. Otherwise there's a problem with the envelope

Re: x0xb0x mod help needed

Here: http://www.ladyada.net/wiki/x0x/mods

bass boost: https://www.subatomicglue.com/x0xl0g/mo ... _boost_mod

Btw slide timing, if we do the mod in such a way that we can really hear, a lower pitch of the slide, irremediably the tune of the VCO will be a bit lower.

I just ordered all the components to build it. (I had bought the PCBs last year, built was pending). I should start the year well by building this vocoder i've been dreaming about for a long time. :tu:
