... ISA MIDI interface. The CS4236B/37B/38B MPU-401 UART function transmits the MIDI data received over the ISA bus to the CS9236 (and to the Joystick MIDI Out pin) in serial format. The CS9236 interprets the MIDI messages and generates the appropriate musical sounds. These sounds are output in serial digital audio format at the CS9236 SOUT pin ...

... The NOTE OFF velocity value is ignored by the CS9236. A note can be turned off using the NOTE OFF message (status byte = 8nH) or using the NOTE ON message (9nH) with velocity = 00. The NOTE ON message with velocity = 00 is defined NOTE OFF message with NOTE OFF velocity of 40H (this allows long strings of NOTE ON and NOTE OFF events to be sent as data bytes only using running status) ...

... Some of the instruments implemented in the CS9236 include a default pitch envelope (the pitch of a note begins slightly sharp or flat, and then ramps to the final pitch for the note). For notes with default pitch envelopes, pitch modulation (vibrato) will begin only after the pitch envelope has reached final pitch ...

... The PAN message (MIDI Controller 10) is used to control the left/right output placement for notes played on the specified MIDI channel. A PAN value of 0 indicates hard left, 64 indicates center (equally balanced between left and right), and 127 indicates hard right. The CS9236 implements an “equal-power” pan scaling as indicated by the following formulae: Left_scaling = ((127 - PAN_value) / 127) ^ 0.5 Right_scaling = (PAN_value / 127 ...

... MIDI channel. Each melodic instrument (MIDI channels 16) and each individual percus- sion sound (MIDI channel 10) implemented in the CS9236 has a predefined default chorus send level. The chorus send level used when a sound is produced is either the value received from a CHORUS SEND LEVEL message (MIDI Controller 93) or the default for the melodic instrument (or percussion sound) currently selected on the specified MIDI channel, whichever is greater ...

... MIDI “Registered Parameter” data is transmitted to the CS9236 using controller numbers 100 (Registered Parameter LSB), 101 (Registered Parameter MSB), 6 (Data Entry MSB), and 38 (Data Entry LSB). To transfer parameter data to the CS9236, the parameter number for the parameter to be updated is first selected using MIDI Controllers 100 and 101, and then the data value for the selected parameter is transmitted using controller numbers 6 and 38 ...

... When the CS9236 detects an ACTIVE SENSING message, it begins operating in Active Sensing ON mode. In Active Sensing ON mode, the CS9236 monitors the elapsed time between receipt of MIDI messages. If the elapsed time exceeds 372 ms., then the CS9236 executes ALL SOUNDS OFF and RESET ALL CONTROLLERS on each MIDI channel and returns to Active Sensing OFF mode ...
