- Nano GND PIN to the top PIN of J4 on Garvuino (green cable on the picture)
- Nano RX0 to the second hole of the left socket of Garvuino (brown cable on the picture)
- Nano D3 to the left PIN of AY>L on Garvuino (red cable on the picture)
Plug the Nano to the USB power cable and the mini-jack to your sound input (your soundcard line-in for example).
Then, you can tweak /arduino_sketches/others/the_synth_midi/the_synth_midi.ino and map some rotary pots to a midi controller.
With gmidimonitor, you can find the cc values of 4 rotary pots and configure these values in the sketch :
#define mWave 10 // pots 1 #define mEnv 11 // pots 2 #define mLength 91 // pots 3 #define mMod 93 // pots 4
Upload the sketch and plug your MIDI IN to the Garvuino. If you turn the 4 pots on your MIDI controller, the RX LED should blink on the Nano and if the audio is properly configured, you may even hear some sounds !
Here are some examples (some noise reduction, normalization and compression have been applied in Audacity) :
In this file, you will listen to 3 differents hi-hat, kick and snare and 2 sound effects. You might be frighten by the last one so don’t push the volume too high !
Thanks again to Garvalf for his help and the cool piece of hardware !
