Features

Link to this section

The Omnichord is an electronic musical instrument with an automatic accompaniment function and is equipped with a harp sensor (strumplate). Your pre-selected chord is electronically matched to the four-octave strumplate so you can strum the correct chord progression for almost any song.

The Omnichord was created in 1981 with the aim of being an electronic instrument similar to an autoharp. Even when the last model bearing the Omnichord name was discontinued, its popularity remained undiminished, and in response to customer demand, Suzuki decided to release the OM-108.

• Perform a song on this unit with a sound generator of a MIDI device (such as a synthesizer or a digital piano).

• Play this unit in synchronization with a MIDI device (such as arranger keyboard and a sequencer).

• Record performance sounds on a sequencer or a PC (DAW).

■ About MIDI channels

MIDI has 16 MIDI channels that transmit various MIDI messages. MIDI devices communicate through MIDI messages via a MIDI cable.

This unit uses five MIDI channels that transmit playing information (such as operations of chord buttons or strumplate).

To transmit MIDI messages as intended, you need to match the MIDI channel settings on a transmitting side (this unit) and a receiving side (MIDI device). For details, refer to “MIDI information” ().

■ About MIDI clock

MIDI clock is a signal transmitted at regular intervals and used for synchronizing the tempo of connected MIDI devices.

This unit transmit MIDI clock signals synchronized with the rhythm tempo. This enables you to play back automatic accompaniment or auto rhythm on the MIDI device (such as an arranger keyboard or drum machine) in accordance with the tempo of this unit.

*1: When this unit is in keyboard mode, the “omni 1” voice will be monophonic locally, but MIDI will transmit all note messages according to the keys played.

*2: This message will be transmitted in synchronization with operations of the [STRUMPLATE Volume], [RHYTHM Volume] and [CHORD Volume] knobs when “Volume CC” is set to “On” (). This allows you to adjust the volume balance when performing music. Some MIDI devices may not support this function.

*3: This message will be transmitted in synchronization with operations of the [STRUMPLATE Sustain] knob when “Decay/Release CC” is set to “On” (). Some MIDI devices may not support this function.

About Decay/Release CC

Decay/Release CC

Description

On

The Decay/Release CC value changes in response to [STRTUMPLATE Sustain] knob adjustments.

This is effective when you play sound of an instrument whose sound fades-out, such as a piano or guitar.

Since the gate time depends on touching/releasing the strumplate (or pressing/releasing a chord button in keyboard mode), you can express a finer musical nuance.

Off

You can adjust the time taken for a sound to stop after the sound starts.

This is effective when you play sound of an instrument whose sound does not fade-out such as an organ or string voice.

If the time is set on maximum, the gate time becomes infinite (the state of “note on” continues until you press another key or tap the Instant OFF plate).

For an instrument whose sound fades-out such as piano or guitar, it prevents the sound from abruptly stopping.

■ MIDI transmit preset

This unit uses five MIDI channels to transmit the note messages (control information of the main voice, chords, bass, sub voice and drums).

By selecting a MIDI transmit preset in accordance with your purpose, this unit automatically controls how each note message is transmitted.

Preset 1 (Accomp and Strumplate voice)

• Transmit channels: CH1 to CH3

This preset transmits playing sounds of the strumplate (melody in keyboard mode), chords and bass to a multitimbral MIDI sound generator.

Example:

Play the strumplate, chords and bass while beating out a rhythm pattern of the arranger keyboard in synchronization with MIDI clock of this unit.

MIDI information: Sound generator, Auto rhythm/, automatic accompaniment, Arranger keyboard, OM-108, Note:, strumplate (CH1),, chord, bass, Clock
Original illustration · select to enlarge

Preset 2 (Accomp and Two Strumplate voices)

• Transmit channels: CH1 to CH4

This preset transmits playing sounds of the strumplate (melody in the keyboard mode), chords and bass to a multitimbral MIDI sound generator.

Since strum sounds are transmitted to both CH1 and CH4, you can assign a different voice to each channel to create various sound effects.

Example:

Play the strumplate (in two different voices), chords and bass while beating out a rhythm pattern of the arranger keyboard in synchronization with MIDI clock of this unit.

MIDI information: Sound generator, Auto rhythm/, automatic accompaniment, Arranger keyboard, OM-108, Note:, strumplate (CH1/4),, chord, bass, Clock
Original illustration · select to enlarge

Preset 3 (All Out)

• Transmit channels: CH1 to CH4, CH10

This preset transmits playing sounds of the strumplate (melody in keyboard mode), chords. bass and drums to a multitimbral MIDI sound generator.

For information about drum note messages transmitted by CH10 on this unit, refer to “Drum map” ().

Example:

Apply note messages of this unit without using automatic rhythm/automatic function of an arranger keyboard.

MIDI information: Sound generator, Auto rhythm/automatic, accompaniment (disabled), Arranger keyboard, OM-108, Note:, strumplate (CH1/4),, chord, bass, drum (CH10), Clock (Internal)
Original illustration · select to enlarge

Preset 4 (Strum Only)

• Transmit channels: CH1

This preset transmits playing sounds of the strumplate (melody in keyboard mode) only.

Select this preset when you want to add a performance of the strumplate to a MIDI sound generator of a single timbre (such as an electronic piano) or music created on DAW.

■ Types of main voices

Voice

Description

Sound continuity

Mellow Pulse

This voice reproduces the classic sounds of “OM-84” which is an Omnichord released in the 1980s. To create this voice, the analogue sound generator circuit of “OM-84” is incorporated into “OM-108”.

Harp

This voice reproduces sounds of a pedal harp used in an orchestra. On this unit, make a chord change using the chord buttons instead of pedals.

Celeste

This voice reproduces the soft and subtle sound of a struck idiophone called “Celeste”.

A. Piano

This voice reproduces sounds of an acoustic piano (grand piano) used in orchestra. It is difficult to play fast arpeggio using piano keys but the strumplate allows you to play it easily.

Guitar

This voice reproduces the sound of a guitar with steel strings.

FM Piano

This voice reproduces electronic piano sounds of a digital synthesizer released in 1980s and is suitable for ballad songs.

Organ

This voice reproduces sounds of a Hammond organ, created by a combination of fifth drawbar setting and chorus effect.

Vibes

This voice reproduces sounds of a vibraphone (a metallophone equipped with spinning fans at the top of the resonator tubes). We recommend tapping the strumplate with multiple fingers instead of sliding when you use this voice.

Banjo

This voice reproduces sounds of a 5-strings resonator banjo often used in country music. We recommend tapping the strumplate alternately and quickly with multiple fingers instead of sliding when you use this voice.

■ Types of sub voices

Voice

Description

Sound continuity

Tremolo Pulse

As with Mellow Pulse, this voice reproduces the classic tremolo effect sound of “OM-84”.

Synth Strings

This voice reproduces orchestral strings sounds of synthesizer. Compared to the actual sounds, this voice has soft and flat traits so that it harmonizes well with other timbres.

Synth Strings (Octave Unison)

This voice reproduces orchestral strings sounds of synthesizer in octave unison which makes the sounds more majestic.

Mellow Synth Pad

This voice reproduces mellow synth pad sounds. By mixing with other timbres, you can create a deep atmosphere.
