/ Table d'implémentation / Gráfico de implememtación *0 PSR-220/230 function as 16 MIDI channel multi-timbral tone generator. The Remote Keyboard channel can be set by the panel settings. The designated channels on the PSR-220/230 can be controlled by an external device and receive the following data: • Note Off • Note On • Contorl Chanage: Bank select MSB, LSB Volume Pan Sustain Reverb depth All sounds off Reset all controllers • Program Change • Exclusive ( Panel voice / GM voice select ) *1 Bank select transmission: The LSB is fixed at 00H. Bank select reception: The bank select MSB is used for melody voice and rhythm voice switching. MSB 00H: Melody voice. MSB 7FH: Rhythm voice. The bank select LSB is ignored. The bank select on the channel 10 is ignored. No voice change will occur when only a bank select is received. When a program change is received, the latest bank select value is used. *2 RPN transmits and receives the following data: Pitch bend sensitivity: BnH, 64H, 00H, 65H, 00H Fine tuning: BnH, 64H, 01H, 65H, 00H Coarse tuning: BnH, 64H, 02H, 65H, 00H Null: BnH, 64H, 7FH, 65H, 7FH *3 Reset all controllers. Pitch bend, modulation, expression, sustain, sostenuto, and registered parameter number are returned to their default values. Portamento is reset. *4 Exclusive. < GM1 System On > F0H, 7EH, 7FH, 09H, 01H, F7H All parameters except MIDI Master Tuning are reset to their default values. < DISK ORCHESTRA ON > F0H, 43H, 73H, 01H, 14H, F7H < DISK ORCHESTRA OFF > F0H, 43H, 73H, 01H, 13H, F7H < MIDI Master Volume > F0H, 7FH, 7FH, 04H, 01H, ll, mm, F7H Allows the volume of all channels to be changed simultaneously (universal system exclusive). "mm" is used as the MIDI Master Volume value ("ll" is ignored). The relation between MIDI Master Volume value and the actual volume is the same as the one between control change master volume value and the actual volume. The default value for "mm" is 7FH. This value is reset by a GM1 System On message. < MIDI Master Tuning > F0H, 43H, 1nH, 27H, 30H, 00H, 00H, mm, ll, cc, F7H Allows the pitch of all channels to be changed simultaneously. "mm, ll" is used as the MIDI Master Tuning value, and the actual tuning value is represented as follows: T = M x 200 / 256 - 100 Where T is the actual tuning value in cents. M is decimal value represented by 1-byte using bits 0..3 of "mm" as the MSB and bits 0..3 of "ll" as the LSB. The default values of "mm" and "ll" are 07H and 0FH, respectively. "n" and "cc" are also recognized. This value is not reset by a GM1 System On or Reset All Controllers message. < Panel Voice > F0H, 43H, 76H, 1BH, cc, vv, F7H This message alternately selects Panel voice or GM voice. cc: MIDI channel vv: 00 = GM voice mode, 01 = Panel voice mode *5 Internal / External clock selectable. *6 Start / Stop message is transmitted. Start / Stop message is received as a message for "STYLE". GM System Level 1 The existing MIDI protocol allows performance and other data to be transferred between different instruments, even if they are from different manufacturers. This means, for example, that sequence data that was originally created to control a tone generator from manufacturer A can also be used to control a different tone generator from manufacturer B. Since the voice allocation in different devices from different manufacturers is usually different, however, appropriate program change data must be transmitted to select the right voices. The General MIDI protocol was developed to minimize confusion and the need for re-programming when playing software created by one MIDI device on another. This has been achieved by defining a standard voice allocation in which the same or similar voices are accessed by the same program change numbers or MIDI channels. The current standard recognized by the International MIDI Association is known as "GM System Level 1." The PSR-230/220 voice allocation complies with the GM System Level 1 standard. 47
