For example, sending Proram Banks every 20ms for a period of 1 second will cause the Help message for the key to be displayed, just as if the key on the front panel had been 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 the 0. 0 position in the current matrix, just as if those two buttons were pressed simultaneously. 0x11 Card Name Message This message which can be sent only via MIDI to the PCM 90 allows a card to be renamed. The name of any currently-loaded card may be learned using the Configuration Response.

If the substitute row value is set to 0x0E, then a custom controller is attached to this position (the column value determines which one). A soft row position may be deassigned if Row and Column are both set to 0x0F. If the substitute row value is 0x0E (custom controller), then this field may go from 0-3. 8 9 0n 0xF7 Substitute Column (0-9) End of SysEx 15 PCM 90 MIDI Implementation Details Lexicon 0x13 Patch Assignment Dump This bidirectional dump contains the state of a particular patch in the currently running effect.

This format is used so that a new patch destination can be selected while maintaining the contour of the patch table.

Out-of-range values will be clipped. 17 000i iiii 7 more 7-byte point packets. . . 67 0xF7 End of SysEx If this message is improperly built, for example, if points are out of range or are not defined in ascending order, the PCM 90 will attempt to correct the data. The message: "Bad patch data was corrected" will be displayed 16 Lexicon PCM 90 MIDI Implementation Details 0x14 Knob Message Host to PCM 90 only. (In SysEx Automation mode, the PCM 90 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. The current MIDI Program Change mode selection (mapped, chained, off, etc) is ignored.

[. . . ] In some store operations, may indicate that a card is write-protected Operation failed Can't dump register 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. The destination of the dump is not overwritten. Bad patch data was corrected A program load failed because of corrupt patch data, probably the result of bad data in a MIDI transfer of effect data. [. . . ]
