Attaching an MB-24 Level Meter
Connecting the MB-24 to the VS-2480
1. With the power to the VS-2480 and the MB24 turned off, connect the VS-2480’s
MIDI OUT to the MB-24’s MIDI IN using a MIDI cable.
2. If you want to connect another MIDI device to the VS-2480, connect its input to the
MB-24’s MIDI THRU jack using a MIDI cable.
3. Turn on the power to your devices.

When using the MB-24, set the VS-2480’s MIDI OUT/THRU parameter to Out
(Page 300). To learn how to configure the meter

EXT LEVEL METER (MB-24)
Use these parameters to set the behavior of the MB-24 meter bridge (purchased
separately) attached to your VS-2480. If you’re not using an MB-24, you can ignore these
parameters.
DISPLAY SECTION
The DISPLAY SECTION parameter selects the type of signals shown in the MB-24’s 24
SECTION level meters. They can be turned off, or set to show:
To learn how to attach an MB-24, see “Attaching an MB-24 Level Meter” on Page 382.
Parameter Value: Meters show:
ANALOG INPUT 1-16 the levels received at the VS-2480’s analog inputs
R-BUS/COAX/OPT IN the levels received at the R-BUS and S/P DIF digital inputs
INPUT MIXER 1-24 input channel levels
TRACK MIXER 1-24 track channel levels
FX1-8 RETURN effect processor output levels
AUX1-8/DIR1-8 Aux bus and Direct bus levels
ANALOG OUTPUT analog output jack levels
R-BUS/COAX/OPT OUT R-BUS and S/P DIF digital output levels
The “Supplemental Information” chapter provides further information regarding the
MB-24. See “Roland MB-24 Notes” on Page 396.

Roland MB-24 Notes
The optional MB-24 Level Meter Bridge adds a full-sized meter array to your VS-2480.
To learn how to connect and MB-24 to your VS-2480, see Page 382. “EXT LEVEL METER
(MB-24)” on Page 360 explains how to configure the MB-24 for use with the VS-2480.

When used with the VS-2480, the MB-24 does not use its PRE EQ, SECTION (1st UNIT/
2nd UNIT), MULTI OUT, FLEX BUS, MULTI IN, INPUT, DIM,” or TALKBACK
indicators. Also, you may occasionally notice that PRE EQ and 1st UNIT light
immediately after the MB-24 is turned on. This does not indicate a malfunction.

The MB-24’s tick indicator—when the TIME DISPLAY
parameter is set to MEASURE/BEAT—shows one-tenth
the actual number of ticks since there are only two digits
available for this purpose, as shown here.

a Tascam MU1000 meterbridge for DM3200 or DM4800, im pretty sure it will be compatible with the VS2480

Manual for MB-24

Now all I need to do is figure out how to control nearly 500 LEDs efficiently with a handful of DOUT modules..

public void HandlePolyPressure(object sender, Sanford.Multimedia.Midi.ChannelMessageEventArgs localE)
   {
   ...
   ...
   // This is to emulate Roland MB24 meterbridge
   if (localE.Message.Command == ChannelCommand.PolyPressure &&
   localE.Message.MidiChannel==15)
      {
      if (localE.Message.Data1<24 &&
         localE.Message.Data2!=meterlevel[localE.Message.Data1])
            meterlevel[localE.Message.Data1] = localE.Message.Data2;
      pictureBox1.Invalidate();
      }
