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".
Planned features are:
- USB MIDI Gadget/Device
- 2 MIDI channels
- Dual pitch CV output (1V/oct)
- Dual gate output
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.
