MIDItio

MIDItio Rendering

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".

MCU

The primary concerns dictating the choice of MCU are:

1. Built-in USB

1. Built-in Digital to Analogue converters (DAC) - preferably 2

1. 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.
