... and there's a special present for miniAtmegatron owners!
Here's a preview of the Odytron port for the miniAtmegatron. Turn the miniAtmegatron into a totally different synth engine! The Odytron emulates the features and sound of a classic analogue synth in 8-bit. The synth has 2 filters, 2 oscillators, ring mod, white noise and much much more.
Here's a very rough and ready video demoing it.
The controls are virtually the same as the normal miniAtmegatron. Key differences are:
- Distortion and Phaser knobs control oscillator frequency offset.
- Amp LFO knob controls the overall amplitude output offset.
- Portamento/Wave crusher function only controls portamento
- Waveform function cycles through several combinations of oscillators, noise and ring mod
- Filter function cycles through, off, soft filter, hard filter (more resonant)
- LFO shape function cycles through several routings of the square, saw and S&H to oscillator freq and filter cutoff
- Xmassy sequence in the sequencer, which auto-increments through patterns
- Install Arduino IDE. Run it up once, then close it.
- Download Libraries 2.6. Then put the contents in /*documents folder*/Arduino/Libraries/
- Download the miniAtmegatron Odytron arduino sketch. Put the contents in /*documents folder*/Arduino/. Then double click SsMinOdytron.ino
- Remove the miniAtmegatron shield from the Arduino Uno.
- Attach the jumper onto the Arduino Uno, as shown in the instructions.
- Reattach the miniAtmegatron shield.
- Plug in the USB. Goto Tools->Board->Arduino Uno/Genuino. Goto Tools->Port->COMM** (your Arduino Uno).
- Click upload button (top left, second icon in).
- That's it. If you want to use the miniAtmegatron with MIDI, you'll need to remove the header again.
Merry Xmas! If you run into any issues with it, just put a message on the forum.
