MIDI Sequencer
English version below.
Componenti principali Hardware:
- Arduino
- MIDI Shield (qui e qui)
- Rainbowduino
- RGB LED Matrix
- Firmware per Arduino preso da SimplenZAR, modificato per dialogare con Rainbowduino per la visualizzazione e semplificato nella parte sequencer (per renderlo minimale e più facilmente modificabile) (MIDI_seq.zip)
- Firmware per Rainbowduino preso qui
- Il primo pulsante in alto sul MIDI Shield commuta tra la modalità SET e la modalità PLAY
- in modalità SET il secondo pulsante commuta tra NOTE e PITCH
- in NOTE (led verde acceso) il potenziometro in alto serve a selezionare lo step e il terzo pulsante commuta noteon/noteoff
- in PITCH (led rosso acceso) il potenziometro in alto serve a selezionare lo step e il potenziometro in basso serve a selezionare il pitch
- in modalità PLAY i segnali MIDI vengono inviati alla MIDI OUT del MIDI Shield

Reading this post on createdigitalmusic, we decided to build a very simple MIDI sequencer, based on SimplenZAR, semplified on the sequencer side (we are not a musicians and we don't know music at all), but improved (we hope) on the visualization side.
Main Hardware components:
- Arduino
- MIDI Shield (here and here)
- Rainbowduino
- RGB LED Matrix
Main Firmware components:
- I took the Firmware for Arduino from SimplenZAR and I modified it to comunicate with Rainbowduino (MIDI_seq.zip)
- Firmware for Rainbowduino here
- the first button on top on the MIDI Shield switches between two modes: SET and PLAY
- when the first button is on the SET mode, the second button switches between NOTE and PITCH modes
- in NOTE mode (green led turned on), the potentiometer on top is used to select the step and the third button switches between noteon/noteoff
- in PITCH mode (red led turned on), the potentiometer on top is used also to select the step and the potentiometer on bottom selects the pitch
- when the first button is on the PLAY mode, the MIDI signals are sent to the MIDI OUT of the MIDI Shield.
Software on PC: SO Linux (Ubuntu Studio 10.10), JACK audio server and a software sinth ZynAddSubFX.
