# Hi, while I was looking some examples for my chip design class I
came across with this site:
http://www.fpga.synth.net/pmwiki/pmwiki.php?n=FPGASynth.PhaseDistortionOscillator
where it talks about the idea of Phase Distortion Oscillator:

You can change it with the slider and see its effects. (There
is some aliasing, because I did not used any interpolation for reading
from the table)
I get some crackling noise when I move the slider, is this what you're
talking about? It would be cool to avoid this, since I
i did a patch a while back that uses something similar to the phase
distortion algorithm used by casio cz-series synthesizers:

Ugur, here is your original patch with the expr converted into expr~
also, you can get some really cool resonant filter sort of sounds by really
distorting the phase (like 10 times). i added a slider for that too.

# Your technique of using expr~ and creating the waveform on the fly
(rather than trying to calculate it in a table and getting clicks and
glitches) is great! Now the parameters are real-time tweakeable, as
Atte requested!
# The problem using a partial function is the discontinuity in its
slope.
yeah, that's really lush now. great stuff!

...and you can also get some squelchier sounds by increasing those sliders
to a larger range, and playing the phasor~ at lower frequencies.
