DAISY SEED BREAKOUT BOARDS

Handy Breakout PCBs for the electrosmith Daisy Seed that can be very helpful for prototyping, especially when working with eurorack signals.

DAISY SUB
I developed my own eurorack module for the Daisy sub module.

I can write custom code (I prefer Max Gen) and flash it to this module and then use it as standalone instrument.

Firmwares I have written include:
A granular synth
A multi effects module
A Reverb
An euclidean sequencer
Utilities: LFOs, Clock with probabilistic trigger outs, Bernoulli Gates and others.

PLUS MINUS

PlusMinus\u201c is a digital bitcrush, distortion, filter and gate effect.


Main goal in the development was to find the balance between raw glitch mayhem and smooth gritty beauty. 

More info here<\/a>.

The development of the \u201ePlusMinus\u201c was supported by \u201eDie Beauftragte der Bundesregierung f\u00fcr Kultur und Medien (BKM)\u201c, \u201eNeustart Kultur\u201c, \u201eDeutscher K\u00fcnstlerbund\u201c.
