0x18 System Setup Dump
This dump, which is both transmitted and received by the PCM 90, contains all system parameters (those
parameters that are not part of a preset).
Note that when the PCM 90 receives a current setup (0x7F) it ignores parameter #10 (device ID) and
parameter #11 (SysEx enable). Those values can only be changed from the front panel or by restoring
a setup from internal memory or card.

6 0iii iiii Setup ID 0x7F=Current; 0-4=Internal; 5-9=RAM Card. A RAM card
may be detected using the Configuration Response.

short param value
(LS first) for first param These parameters correspond by index with Type 0 System
parameters. The SysEx packet is sized to hold 50 such
parameters. The actual count of system parameters is 43, so
the remaining parameter slots should be regarded as re-
served and set to zero. The ranges for the parameters are
listed in Appendix F: System (Type 0) Parameters.
