The Effects and Parameters

Handy pitches:

D#0=19.445Hz

A4=440Hz

B5=987.77Hz

D#8=4978Hz

D#9=9956Hz

Test Tone is an audio sine wave

generator with its output quantized
to correspond with the pitches of a
chromatic scale (A = 440 Hz) over
a nine-and-one-half octave range.
It is provided primarily as a conve-
nient way of generating test tones
and tuning references.

The Level and Note parameters

allow it to be used in musical and
sound effect applications as well.
It can be “played” from a MIDI
keyboard or sequencer by patch-
ing Last Note to Note and an ADR
to Level (use MIDI Gate to trigger
the ADR). Other useful patch
sources for controlling pitch in-
clude: S/H, MIDI Arpeggiator and
the Random Generator.

Bal controls the relative level of

left and right output attenuation.
When Bal=-50, the left output has
no attenuation, and the right out-
put is fully attenuated. When
Bal=0, neither output is attenu-
ated. When Bal=+50, the left out-
put is fully attenuated and the right
output has no attenuation. Level
and Bal can be patched to a global
LFO to get tone bursts, etc. Pitch
accuracy is better than 1/4 cent.
