saw-table - last parameters?

There are some pre-built tables - at the end of the list there are 2 parameters which I’m not sure what they do:

  1. (hz-to-step 1)
  2. T

(setf saw-table (pwlvr -1 1 1))
(setf saw-table (list saw-table (hz-to-step 1) T))


A wavetable is a list of the form
(sound pitch-number periodic)

(hz-to-step 1) gives the MIDI note number for a frequency of 1 Hz.

“T” means “true” (in this context, the wavetable is periodic)
