HEALER SYNTH FIRMWARE UPDATED

05.25.2010


Before heading out to Maker Faire Bay Area, I managed to polish off a new version of the Healer synth code for use with MidiVox - woohoo!

Version 2 of the firmware saves customized parameters (filter, waveform, etc) to the Arduino’s built in EEPROM. Whenever the MidiVox’s RESET button is pushed, two quick flashes of the DATA LED confirm that a save+reset has occurred.

I’ve also disabled the velocity response and its relevant control parameter after figuring out they were to blame for some notes becoming ‘stuck’ on. Personally, I’m not a big fan of note velocity and never thought it felt quite right on a monophonic synth like this. That being said, if anyone’s sad to see velocity go (is that a pun?), please let me know in the comments and I’ll consider reimplementing it as an option in the next revision.

Healer v2 can be downloaded here.
