Need Advice! Using capacitive sensing to control synthesizer made in processing?

Hi all, I've recently got myself an Arduino uno board and have been having great success in making capacitive sensors. I was shocked how quickly I've picked it all up. I've also been using processing for a project to make an interactive synthesizer using the beads library.

I was wondering if anyone knows how to use the serial port values given out by the Arduino to control the synthesizer made in processing. I've found information on using firmata, but is it compatible with the capacitive sensing library on the arduino? I've also tried experimenting with methods of using the Arduino's serial values to get a similar effect in music software such as Max/MSP, and I think this is also an option for what i want to do.

Does anybody have any suggestions on how I could do this?
Links to useful web pages would be great.

Thank you all advice is greatly appreciated, Liam.
