OscN noninterpolating wavetable oscillator

OscN.ar(table, freq, phase, mul, add)

Noninterpolating wavetable lookup oscillator with frequency and phase modulation inputs.

It is usually better to use the interpolating oscillator.

buffer - buffer index. the buffer size must be a power of 2. The buffer should NOT be filled using Wavetable format (b_gen commands should set wavetable flag to false. Raw signals (not converted with asWavetable) can be saved to disk and loaded into the buffer.

freq - frequency in Hertz

phase - phase offset or modulator in radians
