SUPPLEMENTAL INFORMATION MIDI SPECIFICATIONS Program Change Program change messages can be received only when the Effect section is in Memory mode and Manual mode. The program change number correspondence for receiving is the same as that for transmission. The MIDI receive channel is also set to 1. System Realtime Messages Status bytes: F8, FA, FB, FC These are transmitted, but not received. Status bytes: F9, FD, FF These are neither transmitted nor received. Status byte: FE (Active sensing) This is transmitted, but not received. BULK DUMP Reception of bulk dump data is possible in all but the following conditions: * Demo mode * Tuner mode * MIDI Bulk Transmission mode * While Backing section parts are being played * During recording and editing in the Backing section * During editing of effects Transmission of bulk dump data is executed in the MIDI Bulk Transmission mode; when "ALL" is selected, data is transmitted in the following order: Manual effect, all Memory effect programs, all songs and System setup. When data is divided into several blocks before transmission, there is an interval of 100 ms between transmission of each block. Manual Effect Data Bulk Dump x Refer to "EFFECT PARAMETER CHART" on page 130 for details on the data contents. The main parameter settings (made with the parameter knobs) are not transmitted or received. Current Memory Effect Program Data Bulk Dump x Refer to "EFFECT PARAMETER CHART" on page 130 for details on the data contents. All Memory Effect Program Data Bulk Dump When transmitting all Memory effect program data, transmission starts from Memory bank 1 and ends with bank 0. The data is divided into ten blocks before transmission (one memory bank equalling one block), with data from the byte count to check sum treated as a single block. Current Song Data Bulk Dump Song data is output by converting one byte into two bytes of ASCII. When the amount of data is beyond 512 bytes, the data is divided into several blocks before transmission, with data from the byte count to check sum treated as a single block. Song setup bulk data is always transmitted after transmission of the bulk data of a single song. All Song Data Bulk Dump Song setup data for song 1~8 is transmitted in the first block, and the actual song data is transmitted starting with the second block. Song data is output by converting one byte into two bytes of ASCII. When the amount of song data is beyond 512 bytes, the data is divided into several blocks before transmission, with data from the byte count to check sum treated as a single block. Song Setup Data Bulk Dump Song setup bulk data is always transmitted after transmission of the bulk data of a single song. x Refer to Chart 1 below for details on the data format.
