[. . . ] This flag defines the following value field as being an absolute 16-bit value (Flag=0) or a ratio value split into bytes (Flag=1). This flag should be 0 except for those parameters that support Tempo Mode. See the flags field for the appropriate parameters in the appendices describing the algorithms or use the Parameter Specific Response. 9 0000iiii Least-significant nibble of absolute value or numerator byte Out-of-range values transmitted to PCM 80 will be adjusted to legal values. Next nibble of absolute value or numerator byte Next nibble of absolute value or denominator byte Most-significant nibble of absolute value or denominator byte End of SysEx 10 11 12 0000iiii 0000iiii 0000iiii 13 F7 11 PCM 80 Version 1. 10 MIDI Implementation Details Lexicon 0x0C Button Dump This is bidirectional. Those buttons which are transmitted in SysEx automation mode are: Compare, Tap and Bypass.

For example, sending Program Banks every 20ms for 1 second will cause the Help message for the key to be displayed, just as if the key on the front panel were held down. Multiple key combinations can also be sent by sending button messages in quick succession. For example, sending an Up message immediately followed by a Down message causes the user interface to go to position 0. 0 in the current matrix, just as if the two buttons were pressed simultaneously. 0x12 Soft Row Assignment Dump Bidirectional. Assigns a Pro mode slot to a Go mode soft slot.

Notes This is the row/column that will appear in the soft row slot. A soft row position may be de-assigned if row and column are both set to 0x0F. The number of rows and columns is dependent on the current algorithm. 8 9 0n 0xF7 Substitute Column (0-9) End of SysEx 12 Lexicon PCM 80 Version 1. 10 MIDI Implementation Details 0x13 Patch Assignment Dump This bidirectional dump contains the state of a particular patch in the currently running effect.

The message "Bad patch data was corrected" will be displayed. 13 PCM 80 Version 1. 10 MIDI Implementation Details Lexicon 0x14 Knob Message Host to PCM 80 only. (In SysEx Automation mode, the PCM 80 sends parameter values, not knob messages. ) Knobs operate within the current context of the user interface. This message is only useful for a remote controller.

This is the method used in SysEx Automation to send Program Change messages. It may be used in other cases, although the number of bytes is larger than a standard MIDI Program Change message. [. . . ] Cannot store data as requested Usually indicates invalid Bank/offset specification. Bank may not be writeable, or may not be present, or offset may be >49. In some store operations, may indicate that a card is write-protected Operation failed Can't dump register Need algorithm card Displayed when a bank or register which requires a card-based algorithm is being dumped. Effect unchanged No data in dump The dump just received was originally transmitted without an algorithm card and, therefore, does not contain all necessary data. The destination of the dump is not overwritten. Effect unchanged Need algorithm card The incoming dump requires an algorithm card to be decoded. [. . . ]
