G2 controlling a real 303

I've borrowed a 303 for a few days which has the Kenton Mod that gives CV inputs for Slide, Accent, Filter, Gate and CV.

I'm going to fully control this from the G2 with a Kenton Pro 2000 MKII.

Anyone got any tips or patches for controlling this thing in a way which resembles the internal sequencer? Pitch and gate length are obviously simple. Accents are just a gate I presume... what about programming the slides realistically?

Obviously doing things it *can't* do internally is more interesting, but I'd like to start with a simulation first as its more interesting for it to sound 'normal' and then suddenly do something unexpected Smile

I've looked at the 3Phase patch which is a full simulation... but I figure that controlling the 303 directly will be a lot simpler... and that's an impressive but very complicated patch!

I'd like to share everything which I create.

This is the most detail info i found on the net regarding internal timings of the 303...

Aha great stuff, thanks.

That 3.5:2.5 gate time ratio is difficult with the G2 clock module, trouble is the 96 out does not have a 50:50 duty cycle.

I just patched up something using LFOB and my sinex3 circuit, and it seems to work well.

Using LFOB in ClkSync mode is not ideal but the phase control allows you to move the gate in relation to the master clock which is nice.

I think I'll have another go at a 303 style sequencer.

I guess you could just do it at 3.. with a negative edge delay which would have to be set manually... hacky but effective.

I found an useful document that describe some of the devil fish and 303 mecanics : http://www.d16.pl/forums.html?menu=10
Look at the manual of this beautiful VST bassline.

I made a G2 interpretation of this , + some tips taken from the "real world interface" site, especially the capacitor in the accent circuit.

I hope it help. Very Happy

I know this is resurrecting an extremely old thread, but I was wondering if anyone ever completed a g2 sequencer capable of controlling all aspects of a hardware 303.

The reason I ask is that I just got a TBX-303 from Analogue Solutions and am having trouble figuring out how to program slides and accents on the G2 sequencer I've created for it.

Right now my major problem is that I'm not sure how to trigger overlapping notes to activate the slide function. Is there a way I could use a sequencer to trigger some notes that hold longer than others so that the portamento works?

It seems clear within some patch examples I've seen, but translating those to send note length info to the hardware over midi doesn't seem as obvious, but maybe I'm missing something.

Anyone have any ideas?
