Control Buttons - Ecler NUO4 Manual De Instrucciones

7.2.2. Control buttons

The different MIDI messages that control buttons can send are:
•
Unlatch button (normal push switch): it sends two different note messages (Note-On when pressed and
Note-Off when released). It is well suited to control functions needing a temporary state change while the
button is pressed. An example is pitch adjustment that you activate as long as the button is pressed.
•
Latch button (toggle push switch): it sends only one Note-on message whenever it is pressed. It is
appropriate when you want to control functions needing a permanent state change when pressing the
button. An example is the play function of a CD player that is activated by a simple pressing on the button
and vice versa.
•
Any NUO4 MIDI button can send real-time messages (Start, Stop and Continue). Programming is done
with Ecler Control 4 Lab software.
7.2.3. Recommendations
As starting point we recommend to configure all rotary controls in incremental mode and buttons in momentary
mode, and to match your software MIDI control configuration to obtain optimal operation.
If your software does not allow suitable settings of these controls, try to modify the MIDI message that the NUO4
sends with Ecler Control 4 lab.
7.3. Assignment advice for external device functions
There is no universal method to assign functions, since each external device has its own particularities.
Our first advice is to spend the necessary time for indepth knowledge of MIDI control capabilities and how to
program them. Most of the external devices with MIDI control can be set; it means you can define the message
each control will respond to.
The second step consists of choosing the external device functions to control and assigning them to the NUO4
MIDI controls. As you should consider different aspects, we pointed out some of the most relevant ones:
•
Allocate controlled functions in a logical manner, grouping them by blocks in the three LAYOUT sections
(1/2/3). For example, try to group all player-related functions in a same LAYOUT (Play, Cue, Pitch Up...),
all the effect-related ones in another LAYOUT (Flanger, Echo, Delay...).
•
Consider if certain functions have to be kept on the same button independently of LAYOUT position. For
example, if you want the 3B button to execute the PLAY function whatever the LAYOUT and A/B selectors
position is.
•
Think if you want to use channels 2 and 3 in analog or MIDI mode.
In order to reach these objectives, you'll probably need to first edit the NUO4 internal programming and to correctly
configure the external device. From Ecler Control 4 Lab check (and if necessary correct):
•
that the NUO4 controls send the appropriate type of message to execute the desired function in the
external device
•
that the MIDI channel used by the NUO4 is the appropriate one for your external device
•
that messages are the appropriate ones for your external device
•
that controls having a same function send identical messages
