Dynamic control of drum machines.
If you have a drum machine with MIDI, you
can program it dynamically from Emax II keyboard. Run a MIDI cable from the Emax
II MIDI OUT to the drum machine’s MIDI connector, then consult your drum machine
operation manual for information on which Emax II keys control which drums.
ABOUT THOSE MIDI CONTROLLERS...
MIDI controllers cause a lot of confusion all by themselves, so hooking them up to other
instruments doesn’t make things any easier. Fortunately, though, the Emax II is quite
helpful in setting up the MIDI controllers functions.
To understand what a “MIDI controller” is, we first must understand what a “control-
ler” is. A “controller” is a device which provides a means of smoothly controlling a
certain parameter. the Emax II has 6 such controllers: Left Wheel, Right Wheel, Pressure,
Pedal, MIDI Ctrl A, and MIDI Ctrl B.
MIDI however, does not support a “Left Wheel”, “Right Wheel”, or “Pedal” controller
because that would be too machine-specific. Instead, MIDI simply numbers the control-
lers 0 to 63 and lets the manufacturer decide how it wants to adapt these “MIDI
controllers” to its machine. In addition to the controller numbers, MIDI supports two
special controllers that are used so often they have their own commands. These are
“pitch wheel” and “channel pressure”.
The Emax II supports MIDI controller numbers 0 to 31, as well as “pitch wheel” (pwh)
and “channel pressure” (chp), for a total of 33 possible MIDI controllers. The Emax II
allows the user to map each of the 6 internal controllers to any of the 33 MIDI controllers
(PRESET DEFINITION 7).
As an example, let’s say the Emax II’s Left Wheel is set in PRESET DEFINITION 9 to
control pitch, and mapped to MIDI controller #19 PRESET DEFINITION 7. Now, every
time the Emax II’s Left Wheel moves, the pitch changes and the wheel value goes out the
MIDI OUT jack as MIDI controller #19. Also, if MIDI controller #19 comes in the MIDI
IN jack, the Emax II will treat it the same as it does its own Left Wheel, i.e., change pitch.
The Emax II’s MIDI Ctrl A and MIDI Ctrl B, unlike its other four controllers, are only
accessible via the MIDI IN port. However, all 6 controllers can be recorded to the
sequencer and all 6 will be sent on MIDI OUT during playback.
