Turn this Lfo into "audio frequency oscilator" for FM
This is "Kevin's LFO.da".
Where and how would I modify the code to increase it to audio rate?
Also should I modify the "edit source" or "edit dump" version?
(this is what i get when i rightclick on the .da file and select "edit".)

; Low Frequency Triangle and Square Oscilator
; For driving vib, trem, phase, chorus etc.
; Rate is scaled so 0%-100% equals 0.2 Hz to 20 Hz
; Registers
output Square
output Triangle
control Rate=0.4 ; Initial slider position is at 6.6 Hz
static tri=0.0 ; Counter for triangle wave
static dir=1.0 ; direction of wave
temp RateScaled
; Code
interp RateScaled,0.00001666666,Rate,0.0016666666 ; scale the slider control
macs tri, tri,RateScaled,dir ; increment/decrement the tri counter
skip ccr, ccr, 0x10, 0x1 ; if there is a saturation then
macsn dir, 0.0, dir, 1.0 ; flip the direction by skipping one
macsn dir, 0.0, dir, 1.0 ; inversion.
macs Triangle, 0.0, tri, 1.0 ; output the triangle wave
tstneg Square, tri, 1.0, 0.0 ; square the wave and output it.
