Allocate and generate wavetable buffer (256 frames)

Run simple read...

    > d0 <- withSC3 (b_getn1_data 0 (0,255))

and draw buffer

    > plotTable [d0]

Load sound file

> fn_00 = "/tmp/dx7.wav"

> m_00 = b_allocRead 1 fn_00 0 0

    > withSC3 (async_ m_00)

Run segmented read (n-frames of data in m-frame segments)...

> x_01 = do

    > d1 <- withSC3 x_01

and draw buffer
