Llammas

Llammas is Literally Another Monophonic Mozzi Arduino Synth. This MIDI synthesizer has been developped with the Mozzi library, a sound synthesis library for Arduino.

Features

Llammas is a Monophonic synthesizer, with 3 oscillators (supporting different waveforms). It includes 2 LFO with flexible routing, 2 enveloppes (filter & amplitude), 3 operator FM synthesis and a multimode resonnant filter.

Supported filters

• Highpass
• Lowpass
• Bendpass
• Notch

Supported waveforms

• Sine
• Saw
• Square
• Triangle

Protocole

The synthesizer supports the MIDI standard and works with any MIDI controller. Theoretically. In fact, too much MIDI signals at once is badly handled, because of the Arduino's capacity.

Usage

The first potentiometer selects what the four others modify.
