An attempt to build a 303

[lnikj]

I have been demoing the great new 303 modules and have tried to put together something in the spirit of a 303 design following the notes here:

I have not been able to emulate the accent sweep circuit yet (ever ?) but the rest of it is hopefully wired up correctly and you can see the normal 303 controls in the performance section. The first Octagon handles the main sequence and glides; the second does the accents.

The third envelope is a rather inelegant solution to wanting to switch the filter envelope to a short decay time instantly on an accented note. I would rather get rid of it but I couldn’t figure out how to send the right signals to the decay CV.

It doesn't sound a lot like a 303 and the envelope shapes, times, and control ranges could undoubtably be improved. I am not a good 303 programmer either !

I have uploaded the patch if anybody fancies having a go at improving it. You can grab it here:

I have used a couple of Andrew Macaulay modules but the maths modules could be replaced with stock formula modules and the switches could be done differently.

I'd love to hear back from anybody who has a go with it. Cheers.
