Today the Sjöbjörn studio has a mixing console controlled by a PC with outdated software and hardware technology. The hardware requires an ISA-bus to work at all and thereby limits the upgrades that can be made to the computer. The software runs in a DOS environment and has not been updated for a long time as well. This makes working with the mixing console more difficult then it has to be and new features are hard to implement. In this thesis I have developed new hardware so that a more powerful computer can be used which hopefully will allow for a more user friendly interface and make it easier for future upgrades and additions. The thesis presents a solution on how to upgrade the system all the way from the PCcommunication to the hardware designs. The project was based around the Microchip PIC18F4550 microcontroller for the hardware and the Visual Basic.NET programming language for the PC software.
