wheel controller reception/transmission and program change can be toggled on or off. All MIDI operation (in and out) can be disabled, and there is the capability for saving and loading patches. The MIDI receive channel (1-16) can be set for each patch. Four voices can be assigned to one patch that is controlled only via MIDI, with the other four playing a patch controlled only from the keyboard. In this case, wheel effects can be disabled for the MIDI-controlled patch. The Split-8 also recognizes incoming pitch-bend and modulation wheel data as well as note number, note on and off, program change, and tuning request. Some MIDI functions are accessed through a special "MIDI Expand" mode. This is entered by holding down the RECORD button and pressing PROGRAM SELECT 5. All of the LEDs for the PROGRAM SELECT buttons blink, and pressing one of these PROGRAM SELECT buttons now performs one of the following: Selects MIDI mode 1 (OMNI on/poly). If the instrument is in SPLIT mode, data from the MIDI in port will be passed to both programs (as though the synth were in DOUBLE mode). This is the reverse of using button 3, below. Initiates a 2,240 byte system exclusive dump consisting of patch data. The LED for PROGRAM SELECT 2 remains lit during the few seconds that this takes. Selects MIDI mode 3 (OMNI off/poly). This is the reverse of using button 1, above. Not used. Toggles between enable and disable of program changes. Transmission and reception of program changes via MIDI is disabled by default when the synthesizer is switched on. Toggles between enable and disable of both the pitch-bend and modulation wheels. On power-up, MIDI transmission and reception for both is disabled by default. When sending MIDI program (system-exclusive) information to the Split-8, the 64 patches are sent as a string of single-patch packets, so loading single patches at a time is possible. When sending all 64, the synthesizer will sporadically "lose" some patches, presumably because it cannot handle MIDI data transmitted at the speed that modern computers can send it. Most music software allows the user to insert a short delay between packets of sysex information, circumventing this problem. A 50 millisecond delay is adequate. According to the manual, it is possible to have the Split-8 respond to a system-exclusive dump-request, but the manual does not indicate what the request bytes are, nor is there
