Chapter 1. Overview
How a Patch is Structured
Patches are the basic sound configurations that you play during a
performance. Each patch can be configured by combining up to four
tones. Each tone can be turned on/off individually, allowing you to
select the tones that will produce sound.
Tones
On the JUNO-STAGE, the tones are the smallest unit of sound.
However, it is not possible to play a tone by itself. The patch is the unit
of sound which can be played, and the tones are the basic building
blocks which make up the patch.
WG (Wave Generator)
Specifies the PCM waveform (wave) that is the basis of the sound, and
determines how the pitch of the sound will change.
TVF (Time Variant Filter)
Specifies how the frequency components of the sound will change.
TVA (Time Variant Amplifier)
Specifies the volume changes and the sound’s position in a stereo
soundfield.
Envelope
You use Envelope to initiate changes to occur to a sound over time.
There are separate envelopes for Pitch, TVF (filter), and TVA (volume).
LFO (Low Frequency Oscillator)
Use the LFO to create cyclic changes (modulation) in a sound. The
JUNO-STAGE has two LFOs. Either one or both can be applied to
effect the WG (pitch), TVF (filter) and/or TVA (volume). When an LFO
is applied to the WG pitch, a vibrato effect is produced. When an
LFO is applied to the TVF cutoff frequency, a wah effect is produced.
When an LFO is applied to the TVA volume, a tremolo effect is
produced.
How a Rhythm Set is Structured
Rhythm sets are groups of a number of different percussion instrument
sounds. Since percussion instruments generally do not play melodies,
there is no need for a percussion instrument sound to be able to play a
scale on the keyboard. It is, however, more important that as many
percussion instruments as possible be available to you at the same
time. Therefore, each key (note number) of a rhythm set will produce a
different percussion instrument.
* There are four wave generators for each rhythm tone (percussion
instrument sounds).
* LFO is not included in the rhythm tones (percussion instrument
sounds).
