The spring matrix (circularstring-128) is embenned in the file (encrypted with csb64enc and included with <CsFileB> tags. Very useful not to let your included thing get lost! Never had experience with that before.
I added a button and spinbox for choosing and playing the preset, support for MIDI keyboard (you can use also the virtual midi keyboard) to play crazy scanned synth music, a graph for showing the tables used and FFT output of the sound.
It is a lot of fun already and you can go much further from here studying the code, Live Event sheets for parameter combinations, creating new tables for various parameters and so on.
