How The Sequencer Controls The Tone Generator - Yamaha SY77 Operating Manual

How the sequencer controls the tone generator

Although the SY77's tone generator and sequencer are contained in the same unit, these two are indepen-
dent. When the tone generator is in Multi mode, each channel of the multi can be played by a different track
of musical data from the sequencer.

The SY77 can be divided into two sections; the tone generator that produce
sound, and the sequencer that records and plays back data such as notes and
controller movements to control sound. The sequencer is completely independent
of the tone generator, and has its own set of control buttons. This allows you to
start or stop, record or playback at any time even while editing a voice or multi.
It is especially helpful to edit a voice while it is being played by a sequencer
pattern, or to make adjustments to the volume balances or pan settings of a
multi while listening to the song playback.
The sequencer will record data from the SY77's keyboard and also from
MIDI IN, and will playback data to the SY77's tone generator and also transmit
it from MIDI OUT. The tone generator will produce sound in response to data
from the sequencer and also from MIDI IN.
Depending on whether the SONG or the PATTERN button was last pressed, the
sequencer will record and playback data either in Song mode or in Pattern mode.
Depending on whether the VOICE or the MULTI button was last pressed, the tone
generator will produce sound either in Voice mode or in Multi mode. This means
that the sequencer and tone generator can work together in four possible ways
as shown in the following table.

As you can see from the above table, the greatest musical complexity is pos-
sible when the sequencer is used in Song mode to play the tone generator in
Multi mode. However other combinations of sequencer and tone generator will
be useful when creating sequences, patterns, or voices, For example it is often
helpful to keep a sequencer Pattern playing while you edit a Drum Voice.
