Not really a 303, but good fun...
Just a really quick patch for fun, as I saw this question today in the forum. Enjoy!
- v.1.1 - I just added an improved patch to play with in Maschine. I removed the sequencer Block and added another LFO for PWM and then mapped everything in Maschine. The Maschine project of that demo clip is also included, so you can start tweaking right away. I suggest you should also create a dedicated macro page to have all the parameters you'd like to perform with on one page. Hope, you'll enjoy!
