Mini CV Controller
The Mini CV Controller is a low cost, entry level CV to MIDI / MIDI to CV converter / Midi Controller suitable for integration into third party instruments. Additionally, the Mini CV Controller can be upgraded for wireless operation using Bluetooth, which generates Open Sound Control messages.
Since the development of the Dumb Controller, which provided many Australian computer musicians a low cost alternative to imported devices, computer music students have requested an even lower cost alternative for entry level interactive instrument design. Additionally, some artists have requested that a low cost wireless instrument be made available. These requests have been realised in the Mini CV Controller.
In order to keep the cost and power usage to a minimum, the device has a low chip count. Additionally, the number of I/O pins was reduced to a total of sixteen, as opposed to the sixty-four on the Dumb and Smart Controllers. Eight inputs are assigned as CV inputs while each of the remaining eight pins can be configured as digital inputs or CV outputs. These changes resulted in a device that is only 7.5cm x 7.5 cm, which is significantly smaller than the Dumb Controller; and drawing only 10mA of Current (not including the current for each attached sensor), which means that the device can run comfortably on a 9V battery.

The Mini CV Controller can be upgraded for wireless performance through the use of the BlueWave Wireless terminal, a class 1 Bluetooth device capable of 100m transmission range. In combination with a Bluetooth personal computer (PC or Macintosh), the device data can be converted to Open Sound Control messages. In this configuration, the number of inputs can be multiplied by daisy-chaining Mini CV Controllers to the Bluetooth enabled device, enabling the user to expand their system as more funds become available.
The CV inputs have a 10 bit resolution and are scanned every 6ms, while the Digital Inputs have are scanned every 1ms. The PWM frequency ranges from 1.25kHz for 2 bit resolution down to 66Hz for 8 bit resolution.
