Class oscil

Wavetable backed oscillators.

local moscil = require 'melisma.oscil'
local mexpression = require 'melisma.expression'

local wt = moscil.wavetable.sin()

-- Make an LFO for controlling the frequency.
local lfo_oscil = moscil.init(wt,1,1)

-- Map [-1, 1] to [440, 880]
local lfo = (440 + (1 + mexpression.input(lfo_oscil,0) / 2) * 440):build()

local oscil = moscil.init(wt,0,0.5)
oscil:mapf(lfo)

Functions

oscil.init(wt, freq, amp)
