Editing patches (Patch Edit)
The type of sound most commonly played on the MC-808 is called a Patch. Each Patch can contain up to four Tones.
fig.04-001.e
You can turn each Tone on/off to specify which Tones will actually produce sound (p. 89).
Tones are the smallest programmable unit of sound on the MC-808, and are the basic building blocks that make up a Patch. You can’t
play a Tone by itself–it can only be played as part of a patch. A Tone consists of the following five components.

How a patch is organized
Example 1:A Patch consisting of only one Tone
(Tones 2–4 are turned off).
Example 2: A Patch consisting of four Tones.

WG
(Wave Generator)
This selects the PCM waveform material
that provides the basis of the Tone.
* The MC-808 has 622 different waveforms
and two waveforms can be assigned to each
Tone. (Refer to
“Waveform list”
(p. 2) in
“Sound & Parameter List”
.)
All Patches built into the MC-808 consist of
combinations of Tones based on these
waveforms.
TVF
(Time Variant Fil-
ter)
This specifies how the frequency compo-
nents of the Tone change.
TVA
(Time Variant Am-
plifier)
This determines how the volume and pan-
ning of the Tone change.
Envelope
An envelope applies changes to the Tone
over time. There are separate envelopes
for pitch, TVF (filter) and TVA (volume).
For example, you would use the TVA En-
velope to modify the way in which the
Tone attacks and decays.
LFO
(Low Frequency
Oscillator)
Use the LFO to create cyclical changes-or
cyclical “modulation”-in a Tone. Each
Tone has two LFOs. An LFO can be ap-
plied to the Tone’s pitch settings, TVF (fil-
ter), and TVA (volume). When an LFO is
applied to pitch, a vibrato effect is pro-
duced. When an LFO is applied to the TVF
cutoff frequency, a wah-wah effect is pro-
duced. When an LFO is applied to the TVA
volume, a tremolo effect is produced.
