How The Sequencer Controls The Tone Generator - Yamaha SY99 Owner's Manual

How the sequencer controls the tone generator

Although the SY99's tone generator and sequencer are contained in the same unit, they are independent.
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 SY99 is divided into two sections; a tone generator which produces sound,
and a sequencer which 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 balance or pan settings of a multi while
listening to the song playback.
The sequencer will record data from the SY99's keyboard and also from
MIDI IN, and will play back data to the SY99'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.
