Front Panel Indicators, Switches, and Displays
Collectively, all the front panel keys and the Wheel are called switches and the LEDs, six motion control
lamps, and the Liquid Crystal Display (LCD) are called indicators. The MMP-16 is manually controlled
through front-panel switches, while system status is shown via the indicators. The front panel switches are
divided into five groups: the track group, the keypad group, the setup & wheel group, the wheel itself, and
the transport (or motion control) group. The functions for each switch in each group and how their
selection affects the indicators are discussed in this section. The MM-RC remote control unit provides
most of the same functions as the MMP front panel. Note that the CLR (clear or cancel) key will almost
always terminate an operation, and is a good first key to try to cancel an operation.
LED Indicators
Most operating parameters and key functions are indicated through LEDs, as are the output signal levels.
Configuration Settings
To the right of the LCD are 34 LEDs used to indicate the Control mode, the frame and sample reference
sources, the time code format, the sample rate being used, the active sync group, and the state of the
MMP-16 buses (master or slave on the MMR or Lynx buses).
Active Mode/Key Indicators
Above most soft-touch keys there are LEDs to indicate the key status. In some cases they indicate that the
shifted function is active. In other cases they indicate a key status. For example, the LOC (locate) key’s
LED will be on while the MMP-16 is locating, turning off to indicate the transport has completed locating
(the time code in the top and bottom lines of the display should then be equal).
The LEDs above the SEL keys indicate which tracks are selected according to which track function key is
also active. The track function key (EDIT, MON, LOAD TRACK, TRACK or SLIP) that is active will
also have its LED turned on. For example, pressing MON will turn on the MON LED, as well as the SEL
LEDs for all the tracks that are currently being monitored in the headphones. Pressing any SEL key will
then toggle the track between monitor on (when the LED is lit) and monitor off (no SEL LED for that
track). If another track mode key is pressed the SEL LEDs will now indicate that mode’s selected tracks.
Track Status and Metering
Immediately above the track select buttons associated with tracks 9-16 in the MMP-16 are 9 LEDs per
track (for a total of 144 LEDs). These indicate audio signal levels (meter LEDs) & track slip status for
each track.
