STM32F4 Discovery board open source project.

"Ambiantiseur" ( Ambientizer in english) is a very basic synthesizer 

which can produce semi-randomly generated musical sequences with a few effects (delay and phaser).

Demo here : http://www.youtube.com/watch?v=fMWcXrCg1iw

Four potentiometers and one switch allow the user to control the machine.

The two position switch allow you to modify 2 x 4 = 8 parameters :

Switch = 0 ->

	pot1 : tempo

	pot2 : notes scales

	pot3 : delay time (0.6 s max)

	pot4 : delay feedback

Switch = 1 ->

	pot1 : note duration (decay time)

	pot2 : phaser rate

	pot3 : phaser feedback

	pot4 : master volume

When switch is toggled, parameter will be adjusted only when the potentiometer is moved and reaches previous value.

The LEDS light on when the pot is at real position.

That is done for avoiding brutal value jumps. (Could be improved)

The tone generator is an anti-aliased minBLEP sawtooth oscillator with light vibrato.

Wirings :

Switch and pots are 3V board powered.

	switch : PA1

	pot1   : PB1

	pot2   : PC1

	pot3   : PC2

	pot4   : PC4

Three additional pots or switches can be wired on PA2, PA3, PB0. Their values appear in ADC1ConvertedValues[1...2...3] array.

* Tools used for build (on Windows Vista):
