Spiral Synth 2
Note: SpiralSynth isn't being supported any more due to lack of time, and the existance of SpiralSynth Modular. Which is much better featured and developed.
SpiralSynth is a simple polyphonic analogue modelling softsynth that tries to be as easy to use as possible.
(Note: A few features, such as portmento and echo have been temporarily lost for the moment)
To build and install:
If the synth clicks like a skipping CD, you may need to reduce the sample rate in the options window. 22050 should be low enough for most CPU's. (It's default is 44100). You can also try increasing the buffer size or playing with the fragment size and count.
