About MIDI

■ Program Change

Messages which determine which voice to select for each

Part. With a combination of Bank Select, you can select

not only basic voice numbers, but also variation voice

bank numbers.

■ Pitch Bend

Pitch Bend messages are continuous controller messages

that allow the pitch of designated notes to be raised or

lowered by a speciﬁed amount over a speciﬁed duration.

■ Channel Aftertouch

Messages which let you control the sounds by the

pressure you apply to the keys after the initial striking of

the keys, over the entire channel.

The S90 does not transmit this data from the keyboard;

however, the S90 does properly respond to this data when

received from an external device.

■ Polyphonic Aftertouch

Messages which let you control the sounds by the

pressure you apply to the keys after the initial striking of

the keys, for each individual key.

The S90 does not transmit this data from the keyboard;

however, the data is transmitted from the S90’s internal

sequencer.

SYSTEM MESSAGES

System messages are the data related to the overall

system of the device.

■

System Exclusive Messages

System Exclusive messages control various functions of

the S90, including master volume and master tuning,

tone generator mode, effect type and various other

parameters.

General MIDI (GM) System On

(Sequence Play mode only)

When “General MIDI system on” is received, the S90 will

receive the MIDI messages which are compatible with

GM System Level 1, and consequently will not receive

NRPN and Bank Select messages.

F0 7E 7F 09 01 F7 (Hexadecimal)

n Make sure that the interval between this message and

the ﬁrst note data of the song is at least a quarter note

or greater in length.

Master Volume

When received, the Volume MSB will be effective for the

System Parameter.

F0 7F 7F 04 01 ll mm F7 (Hexadecimal)

* mm (MSB) = appropriate volume value,

ll (LSB) = ignored

■ System Realtime Messages

System Realtime messages

Control the sequencer, including Start (FAH), Continue

(FBH), Stop (FCH), MIDI clock (F8H) and Active

Sensing messages (see below).

Active Sensing

Once FEH (Active Sensing) has been received, if no MIDI

data is subsequently received for longer than an interval

of approximately 300msec, the S90 will perform the same

function as when All Sounds Off, All Notes Off, and

Reset All Controllers messages are received, and will then

return to a status in which FEH is not monitored

■

System Common Messages (Transmit only)

System Common messages also control the sequencer,

including Song Select and Song Position Pointer

messages.

n Refer to the MIDI Data Format in the “Data List” book

for more information on the various messages.
