MIDItio is a planned USB Midi to CV device. The device will act as a USB MIDI device connected to a USB host. It will be able to run two channels simultaneously with a CV indicating the pitch and a Gate indicating start and stop.
The name MIDItio is derived from MIDI and the Latin "ditio" which means "control".
Hardware Design
MCU
The primary concerns dictating the choice of MCU are:
- Built-in USB
- Built-in Digital to Analogue converters (DAC) - preferably 2
- Cost
The STM32L151 fits the bill nicely.
Output Amplifier
Without a boost regulator the highest available voltage on the board is the USB VBUS 5V.
