You can navigate through the pages using the A switch, and you enter a page using the B switch.
Once you entered a page you cannot go out, you will have to restart the configurator to access
another page. On each page, a modified parameter is instantaneously stored. The storing process
is validated by a fast flashing of the product’s LEDs.
13.3 MIDI Monitor
The MIDI monitor uses the LEDs to display the type of message and the channel used by the
emitter. It is a powerful tool to help you debug a MIDI configuration issue. If you find that the MIDI
behavior of Le Preamp is not what you expected, this short guide will help you fix the issue.
Flash Color Meaning
What to do?
No Light No MIDI Message received
Control the connection between the MIDI output of your MIDI controller
and the MIDI input of Le Preamp. Control and eventually change the MIDI
cable. Make sure the MIDI controller is configured to send MIDI messages.
Red MIDI message is not a PC
Make sure your MIDI controller is sending PC messages.
Yellow MIDI message not on the active MIDI channel
Set your MIDI controller to the same MIDI channel as your preamp, or set
the preamp to OMNI.
Green MIDI message on the active MIDI channel
Configure your MIDI controller PC so it matches the default Le Preamp MIDI
mapping. Or use the MIDI Learn function on Le Preamp so the MIDI PC you
send triggers one of its functions.
13.4 MIDI Learn
Your Le Preamp can "learn" how to behave depending on the MIDI message it receives from a
MIDI controller. When entering the MIDI learn page, the tube window is white, indicating the Erase
mode.
Function
Process Example
Erase a PC
MIDI controller sends a MIDI
PC, this PC will not be inter-
preted by Le Preamp any-
more
You want your Le Preamp not to react to PC42 . When the tube window is white, have
your MIDI controller send the PC42. You can continue with other PC # you want to
erase from memory.
Program a PC
Channel A is selected, the
MIDI controller sends a PC
that is instantaneously stored
You want the channel Hot Fusion to be triggered by PC84. Your Le Preamp is in Erase
mode (tube window is white) at first. Click on A+B and make sure the Fusion switch
is on Hot. When your preamp is in the correct state, have the MIDI device send the
PC 84. Several PCs can trigger the same channel on Le Preamp. If you send several
PCs while in this state, the Hot fusion will be activated for each and every stored PC.
You can continue by attributing other Le Preamp states (Channel A, B...) to other MIDI
PC, simply by selecting another channel and sending another PC(s) from your MIDI
controller.
13.5 MIDI Channel
This page uses the A and B LEDs flashing to indicate the channel number, OMNI mode or MIDI Off.
OMNI mode
A and B LEDs are on, that is the factory setting. To go into OMNI mode, just select a channel over 16.
MIDI Off
A and B LEDs are off. In this mode, any MIDI message sent to your Le Preamp will be sent to the MIDI output without
being interpreted. When in OMNI, press A or B once to enter this mode. Pressing A or B another time will start the
Channel Selection process. Please note the Multi-Channel function remains active (on or off) even when MIDI is off.
Channel Select
A LED flashes to indicate the decade (off or 10) and B the unity (off, 1 to 6). For example, "14" will be A flashing once
followed by B flashing 4 times, "8" will be A off and B flashing 8 times. After a pause, the flashing sequence is shown
again. Press the A switch to add 10 to the channel number and B to add 1. Going over 16 will bring the MIDI mode
back to OMNI.
