PCM 90 MIDI Implementation Details
0x1E Verbose Dump Message
This dump is only received by the PCM 90. It is provided for use with remote editors to enable and disable
the flashing of MIDI transmission messages during PCM 90 SysEx dumps. This message can also set
an automatic mode wherein a display message is transmitted whenever the display changes (to support
a remote control). Verbose state is NOT remembered by PCM 90 over a reboot cycle. The PCM 90 always
returns to normal mode (Mode 1).

0x1F LED response
When the automatic verbose mode is selected, this dump is trnasmitted by the PCM 90 whenever any
of the LEDs change. The meter values are also included, since it is likely that they have also changed.
When this message is sent, no meter message is sent for the same time period. This is done in order to
lower the data traffic.

Notes
2 (Automatic mode) Do not flash messages on screen. In
addition, automatically send the display SysEx whenever the
display changes. This mode can cause a tremendous amount
of data to be output by the PCM 90, and some computers may
have trouble keeping up.
1 (normal mode) Flash messages on screen. Transmit dis-
play only when requested.
0 (quiet mode) Do not flash messages on screen. Transmit
display only when requested. In mode 0 and 2, no MIDI dump
status messages are displayed.
