second four measures at a reduced volume. The four measure cycle of loud and soft counts will

continue until stopped.

1. Press [COACH] to select “ ”

2. Press [START/STOP] to begin to exercise.

Gradual Up/Down ( )

Practice in “Gradual Up/Down” mode is designed to increase stamina and endurance by gradually

increasing and decreasing the tempo. The speed increases 1 BPM every two beats until the

maximum metronome value is reached. Once you hit the maximum value, the speed decreases 1

BPM every two beats until you return to the original tempo. The process is then repeated. When

“PATTERN” is selected, the speed changes 1 BPM every two measures.

1. Press [COACH] to select “ ”

2. Press [START/STOP] to begin to exercise.

When you press [WRITE] during a performance, the tempo in effect at that time is set as the

maximum metronome value (initial setting: 250). The minimum metronome value is set

according to the tempo set with the TEMPO/VALUE dial or tap input.

* Changing the minimum value resets the maximum value to the initial setting (250).

Step Up/Down ( )

Step Up/Down mode is designed to increase playing endurance by slowly increasing and

decreasing the speed of the metronome. In this mode, the metronome’s tempo will increase by five

beats per minute (5 BPM) after every four measures until it reaches the metronome’s maximum

tempo. After the maximum tempo is achieved, the metronome’s tempo will decrease by five beats

per minute (5 BPM) after every four measures. This will continue until it reaches back to the

metronome’s starting tempo and then repeat the process.

1. Press [COACH] to select “ ”

2. Press [START/STOP] to begin to exercise.

When you press [WRITE] during a performance, the tempo in effect at that time is set as the

maximum metronome value (initial setting: 250). The minimum metronome value is set

according to the tempo set with the TEMPO/VALUE dial or tap input.

* Changing the minimum value resets the maximum value to the initial setting (250).

The frequency for A4 (the middle A on a piano) of a note played by an instrument (a piano, for example) as the

pitch to which all other performers tune their instruments for performances is called the “reference pitch.”

Using MIDI (MIDI Mode)

MIDI (Musical Instrument Digital Interface) is a

universal standard that allows for the exchange of

performance data and other information among

electronic musical instruments and computers. Once

MIDI cables are used to connect together devices

equipped with MIDI connectors, each device can send

data to, or receive data from any of the others.

The DB-90 starts, stops, and displays the tempo in

synchronization with the external MIDI device (device

equipped with MIDI OUT).

When the master device is started or stopped, a MIDI

message for that operation is transmitted.

The slave then starts or stops in accordance with the transmitted MIDI message.

Furthermore, timing clock data corresponding to the tempo is transmitted by the master device.

Slave device synchronizes its performance to this timing clock.

■Data Synchronized with the DB-90

The following MIDI messages are handled during synchronization with the DB-90.

• Start

• Continue

• Timing Clock

• Stop

• Active Sensing

1. Press [MIDI].

“MIDI” lights steadily.

When the external MIDI device is started or stopped, the DB-90 then starts or stops.

2. Press [MIDI] once again.

MIDI mode is cancelled, and the DB-90 returns to Metronome mode.

* You cannot change the tempo with the TEMPO/VALUE dial or through tap input while the DB-90 is in MIDI mode.

Pressing [TEMPO], [LOOP], [TUNE], [PITCH], [COACH], or [TRIG/GUIDE] cancels MIDI mode.

* If the MIDI cable is disconnected during synchronized play, the DB-90 will stop playing.

* Depending on the VOICE for the Beat, the metronome may not sound correctly when the tempo is set to

more than 220. In such cases, select VOICE 3.

* In MIDI mode, you cannot select from memory during performance.
