Beats Per Minute (BPM)
‘Beats Per Minute’ refers to the tempo (speed) of a piece of music� A beat refers to a
quarter note in a measure, so 4 beats would equal 1 measure� 120 BPM would equate
to 120 quarter notes in a minute if only quarter notes were played for a whole min-
ute�
Modulation
To modulate is to continually change the value of a parameter� In the case of this
delay, the parameter that is being continually altered is the delay time� e delay
time is “wiggled” a certain amount of time before and aer the center time, causing
a change in pitch in the wet signal� e amount of wiggle is determined by the Speed
and Depth controls� When this changing pitch on the wet signal is mixed with the
dry signal, the result is a chorus type eect, which sounds like multiple voices are be-
ing played at once�
MIDI
MIDI is an abbreviation for Musical Instrument Digital Interface� is is a standard
of digital communication between musical instrument devices that was developed in
the 1980’s in collaboration with a few music manufacturers� Today, it is the leading
communication protocol between musical instruments� MIDI allows you to change
presets and control knob positions on the Discovery from any device that can send
MIDI information�
