Polypulse : New synth from Lambda Synthetics

Oooh… can’t quite tell how this is working from the videos but I’ve been working on this sort of phase sequencer for a few months in various levels of code / midihub hacking etc as I love the idea and totally missed that someone had built one. Shame it’s not just a sequencer as I would stop building and just buy it.

Off topic on my workings

LFO note triggers was the first attempt. Focused on drums but now realise that melody is even more interesting.

My current version has 4x a list of notes (was originally one, maybe around four) and then 4x four encoders:

  • Square wave LFO frequency control that triggers a note every cycle.
  • Volume control for the midi note outs
  • An encoder for the length of time to pass before a gap between cycles
  • An encoder for how long this gap lasts

This setup is duplicated the four times so you can get four polyrhythmic beats going.

After playing with the midihub prototype I found the best part of it was tweaking the frequency live to make and adjust patterns.

Was building as a web app but might get that Elektra One scriptable midi controller thing and build it for that.

If anyone wants to collaborate I’d love to as doing this for a free and open source thing.
