Allocate and generate wavetable buffer

>             ;let f = [Normalise,Wavetable,Clear]

Fixed frequency wavetable oscillator

> audition (out 0 (osc AR 10 220 0 * 0.1))

Modulate frequency

> let f = xLine KR 2000 200 1 DoNothing
> in audition (out 0 (osc AR 10 f 0 * 0.1))

As frequency modulator

> let f = osc AR 10 (xLine KR 1 1000 9 RemoveSynth) 0 * 200 + 800
> in audition (out 0 (osc AR 10 f 0 * 0.1))

As phase modulatulator

> let p = osc AR 10 (xLine KR 20 8000 10 RemoveSynth) 0 * 2 * pi
> in audition (out 0 (osc AR 10 800 p * 0.1))

Fixed frequency wavetable oscillator

> audition (out 0 (osc AR 10 220 0 * 0.1))

Change the wavetable while its playing

> let f = [Normalise,Wavetable,Clear]
> in withSC3 (send (b_gen_sine1 10 f [1,0.6,1/4]))

Send directly calculated wavetable

> import Sound.SC3.Lang.Math.Window
> let t = to_wavetable (triangular_table 512)
> withSC3 (send (b_setn1 10 0 t))
