Transmitting <system data> causes values to be immediately used in the ATR-1a. Transmitting <program data> or <song data> causes the data to be put into the ATR-1a permanent memory, but the values do not take effect. To have those data take effect, you can:

from the front panel:

in Song Mode: a new Song must be selected.

in Program Mode: a new Program must be selected.

from MIDI control:

in Program or Song Mode, send a MIDI program change message to recall the affected Program or Song. Note that Song or Program down- loads don’t change Modes. You must have the correct Mode selected before transmitting a MIDI program change, or you must transmit a SysEx message to change to Program or Song Mode, as appropriate.

Note: Due to the necessity of writing parameter changes to EEPROM, a delay of at least 200 milliseconds is required after the transmission of Song, Program or System parameter changes.

Note: The ATR-1a does not protect itself against SysEx parameters being out of range. Unpredictable results may occur if out-of-range SysEx parameters are received.
