Fine
The Fine (fine tune) setting determines the pitch o f the
VCO 1 in 1 -cent steps o ver a rang e o f 1 0 0 cents, o r
o ne semito ne. T urning the kno b to the rig ht raises the
pitch, while turning it to the left lo wers the pitch. The
center po sitio n (value = 0 ) is the basic pitch.
Settings:

Edge
The Edg e setting adjusts the sharpness o r smo o thness
o f the edg e o f the VCO 1 wave. T urning the kno b to the
rig ht pro duces a sharper wave, resulting in a harsher
so und. T urning it to the left pro duces a ro under wave,
resulting in a so fter so und. A value o f " 0 " results in a
sine wave.

PW
(Pulse W idth)
The PW setting determines the width o f the VCO 1
pulse wave. T urning the kno b to the rig ht pro duces
mo re harmo nics, resulting in a fatter so und. In g eneral,
pulse width is used to co ntro l the pulse wave; ho wever,
the AN 1 x can use PW with o ther waves as well, fo r a
wider po ssible variety o f so unds than usual.
