STM32F4 discovery board "Dekrispator" synth

[UltraJv]

Ive got one of these evaluation boards coming soon for another project. These boards are very cheap and high spec (uk £20) Thought Id share a very cool open source synth thats been developed by Xav Blue. Just buy the board, program it up with deskripator.hex and off you go. Nothing else to it. it has USB host controller fuctionality :

**Dekrispator features** :

* monophonic
* all digital !
* oscillators with :
* very low aliased analog waveforms with minBLEP oscillators (thanks Sean Bolton)
* 4 OP FM generator
* multisaw (several saws with individual "drifters")
* 10 sine additive generator
* noise
* vibrato
* tremolo
* drive/distortion
* 16 step random sequencer
* several scales to choose from
* 2 parallel filters LP/BP/HP with LFOs
* Effects :
* Echo
* Chorus/Flanger
* Phaser
* random sound/FX patch generator
