Local On/Off

Local is the parameter that allows you to establish whether the keyboard has to play the internal sounds and transmit MIDI data at the same time (Local On), or whether it just has to transmit MIDI data and not play the internal sound (Local Off).

Local Off should be chosen when you wish to use the SP-250 as a mute keyboard, to play another instrument. It should be chosen also when SP-250 is connected to a sequencer via its MIDI IN and MIDI OUT connectors. This will avoid the notes to be played twice, by the keyboard and by the sequencer, producing an annoying “echo” effect.

Normally, you will choose Local On (automatically selected when turning the SP- 250 on), so that playing the keyboard will produce sound.

Hold down the TRANSPOSE/FUNCTION button, and press the PIANO 1 sound selection button. The Local setting will alternate to On/Off each time you press this button.

Local Off	Dark

Note: When the power is turned on, the Local will be automatically set to On.

Program Change

The sound of the SP-250 can be selected via MIDI, by sending a Program Change message on the channel where you wish to assign the sound. The table enlists the Program Change numbers (numbering from 0-29; if the transmitting device uses numbers from 1-30, you will need to increment the number by one).

Transmitting Program Change messages. You can send a MIDI Program Change message to a MIDI device connected to the SP-250 MIDI OUT, to change its sound. When selecting one of the internal sounds of the SP-250 by using the sound selection buttons, a MIDI Program Change number will be transmitted, as shown in the table below.

Receiving Program Change messages. When a Program Change message is received from an external device, the corresponding internal sound will be selected
