signals cannot be correctly tracked due to the constantly shifting input frequency.

The Zero Crossing Counter module can
be used for detecting the pitch of an input
signal. Note that the input signal has to be
fairly simple regarding harmonic content since it’s the zero crossings of the signal which are being detect-
ed. An FM input signal, for example, won’t generate a steady Pitch output signal because the zero crossing
interval varies constantly. It’s also necessary that the input signal is bipolar, i.e. contains both positive and
negative levels. An input signal that never crosses the 0 level value won’t generate any Pitch control signal.
The practical pitch detection range is 40 Hz to 16 kHz

This is a level scaler mainly intended for
modulation signals in FM applications.
You can use it to scale an audio signal level
based on input note values. You set a
break point key and different amplifica-
tion/attenuation slopes for the sections on either side of the break point. This module is also suitable for
creating variable Keyboard Tracking using the control signal output.

Patch this input to e.g. the Pitch or Note outputs of the Keyboard input module (see
). Alter-
natively, use the KBT function (see below).
