The Electrumpet
The Electrumpet is an enhancement of a normal trumpet with a variety of electronic sensors and buttons. It is a new hybrid instrument that facilitates simultaneous acoustic and electronic playing. The normal playing skills of a trumpet player apply to the new instrument. The placing of the buttons and sensors is not a hindrance to acoustic use of the instrument and they are conveniently located. The device can be easily attached to and detached from a normal Bb-trumpet. The device has a wireless connection with the computer through Bluetooth-serial (Arduino).
Audio and data processing in the computer is effected by three separate instances of MAX/MSP connected through OSC (controller data) and Soundflower (sound data).
The current prototype consists of 7 analogue sensors (4 valve-like potentiometers, 2 pressure sensors, 1 “Ribbon” controller) and 9 digital switches.
An iphone which is wirelessly connected to the computer through a WIFI network shows my MAX/MSP patch through a
shared desktop program (iTeleport).
Currently work is been done for a major change in the design. A lot of buttons will be replaced by pressure sensors, an infrared sensor and audio level sensor will be added and the connection will be done with XBEE in API mode without the use of a microcontroller.
