Programming Capabilities

The KAWAI SX-240 offers eight independent programming channels (or "tones"), each with its own DCO-VCF-VCF'EG-VCA-VCA'EG sequence.

The KAWAI SX-240 uses digitally controlled-oscillators (DCOs) — for utmost pitch accuracy. The interval between the two DCO's may be chosen anywhere in a range of up to two octaves. Each programmed sound is stored under an 8-digit name which appears in an LED display labeled "IDENTIFIER" on the panel.

Ease of Operation

Parameter selection during programming is a simple matter of moving a cursor (lighted LED) through the parameter block until the name of the desired parameter appears in the IDENTIFIER section of the panel together with its current value. Rotating the INCREMENT knob then changes the parameter value or turns
it ON and OFF.

Playing the Synthesizer

In addition to the “NORMAL” mode of operation (one sound for the entire keyboard range), the SX-240 can be played in either "SPLIT" or “DUAL” mode. The "SPLIT" mode allows for two different sounds to be played on two different sections of the keyboard. The "DUAL" mode allows two different sounds to be played together.

The bender function provides control over the digitally controlled oscillators (DCO) and voltage controlled filters (VCF). The bender amount can be programmed differently for each tone program. The synthesizer provides PORTAMENTO and GLISSANDO effects which can be easily added and/or removed at any time.

The foot switch allows the player to switch programmed tones without removing his hands from the keyboard.

Built-In Sequencer

The built~in real-time sequencer is capable of recording up to approximately 1500 notes of an actual performance.

Both recording and playback may be synchronized with an external clock signal or drum machine. The SX-24O clock setting is 24 pulses per quarter note.

Musical Instrument Digital Interface (MIDI)

Three MIDI terminals -— IN, OUT, and THRU — are provided. The SX-240 MIDI can transmit and receive keyboard, bender, program select, and release signals. It transmits only on MIDI Channel 1 but receives data on all 16 MIDI channels.

Memory Capacity

The SX~240 is capable of storing 48 Tone Programs in six banks (A through F) of eight patches each as well as eight sets of sequencer data (for a total of 1500 notes).

The synthesizer's edit and exchange functions simplify the tasks of creating new, complex tones and rearranging previously recorded ones.

Tape Interface

Programmed tones and sets of sequencer data can be transferred from the memory to tape - to form a permanent library of virtually unlimited capacity. When this function is activated, the IDENTIFIER portion of the panel gives the procedure
