DPW4Saw
Extension
ExtensionSawtooth via 4th order differerentiated polynomial waveform
Description
Differentiated polynomial waveforms described in their technicalities here: Vesa Valimaki, Juhan Nam, Julius O. Smith and Jonathan S. Abel Alias-Suppressed Oscillators Based on Differentiated Polynomial Waveforms IEEE Transactions on Audio, Speech, and Language Processing 18(4) May 2010, pp 786--798
Internally, uses DPW2 (quadratic polynomial) for frequencies below 400Hz, with a crossfade in the 400-600Hz region to DPW4. DPW4 behaves well then for higher frequencies.
Slightly less efficient than Saw when lots of UGens running, very slightly duller sound.
