No, all my stuff's GPL and there are no strings attached. If you want
to have a look at the code, I have an archive with the dafx material
in: http://music.nuim.ie/vlazzarini/tmp/Dafx08.zip

Out of curiosity, I just checked the cost here on my computer. Takes
about 2.3 secs to do 100 secs of output. Using a buzz instead, is about
2 secs per 100 secs. Not bad.

Subject[Csnd] new bandlimited oscillators (was: Re: UDO question)
Thanks for posting these examples - I finally got the csd ones running 
after I twigged they needed  5.09. Somewhat slow on the G4 iMac (just 4 
voices before breakup), but much better on dual-core, unsurprisingly - I 
will need to lengthen the envelopes to be sure I am genuinely playing 
more than 16 voices (via my 2-octave Oxygen8 controller), but so far so 
good!  One thing - am I right in assuming the loss of waveform shape at 
low frequencies  (looks like bottom partials are reduced quite a bit, 
from about 200Hz), and the just-noticeable latency is because of the new 
ultra-powerful dcblock2 opcode? Presumably for low notes (e.g. 
floor-shaking 50Hz) the order has to be increased pro rata. Higher up 
the range, the waveforms look and sound excellent!
