Manual for MIDI Agente Relay Loop

1. Connecting

1.1 Loops

Connect your guitar effects to the looper: Connect Send signal to the input of an individual effect. Connect output of the effect to Return signal.

When the loop is off, the effect is bridged, the signal is not routed to the effect and it is not received from the efect. When the loop is on, the signal is routed to the effect and received from it back.

If you don't connect Out signal of a loop section, it is automatically internally connected to the In signal of next section.

1.2 Switches

The switch relays A, B, C, D can be used for switching the channels of a guitar amplifier. Switches A+B and C+D have common ground. The connection is like this:

A/B A B Gnd A+B
C/D C D Gnd C+D

If your amp has individual inputs for the channels switching, use an appropriate Y-cable.

1.3 MIDI controller

Connect [MIDI OUT] of your foot MIDI controller to [MIDI IN] of the looper by a MIDI cable. The looper resends all data from [MIDI IN] to [MIDI OUT] so another MIDI devices can be controlled from one source.

The device provides phantom power suply on pins 6 and 7 of [MIDI IN] and [MIDI OUT] DIN7 sockets. So you can connect a foot MIDI controller by a single 7-pin DIN cable. But pay attention that the MIDI controler can interference the analogue circuits of the looper then because it shares the same power supply adapter with the looper. It's better to supply the MIDI controller by another power source.

2. Programming

2.1 Common mode

When the power is switched on, the switcher goes to common mode. It goes to a default program (it is normally program 1 but it can be changed) and the relays, that are programmed for this program, switch on. Using the buttons Program↓ and Program↑ set the program number that you want to use or edit (1 až 128). Using the buttons for individual relays (1 up to 8, A up to D and Preamp) set the required combination of the loops and relays. Then shortly press Save button. The display shortly shows SAV and the combination for selected program is permanently stored in memory.

When the device receives appropriate MIDI message (ex. Program Change on channel 1), it changes the program number. The dots of the top part of the display indicate that the message Program Change, Control Change or Note On was received.

Within each program, you can switch on the preamp. Only its status on/off can be saved, not its gain.

2.2 Global mode

It's important to configure first the device for correct communication with a MIDI controller. It is appropriate to configure global parameters in accordance with your MIDI controller.

Press and hold a while the Save button. The display shortly shows GLB. You will go to the global menu and you can select the items using buttons 1-5. These parametrs can be configured:

1 Channel Number of receiving MIDI channel 1 až 16 or all (ALL) 1
2 Global cmd Global MIDI command PC ... Program Change
CC ... Control Change
Not ... Note On
3 Global CC num Number of Control Change. Applies only in the case when the Global MIDI command is set on Control Change. 0 - 127 50
4 PC range Writing the Program Change numbers on the display 127: in technical format (0-127) or
128: in user format (1-128)
This setting is only about writing the number on the display, according to how other devices of your gear display it (ex. MIDI controller or a computer DAW program); it doesn't affect the Program Change message itself.
5 Default pgm

Program number that is set when the device is switched on.
(Only on models with more than 4 relays)

1 - 128 1

When the global mode is activated, the first parameter is always being edited, ie. MIDI channel. For editing other parameters, press the appropriate button. When the button is pressed, it lits on. (Due to the internal connection, the appropriate loop is also switched on.)

When you have set the global parameters, press the Save button. They are saved premanently then.

2.3 Individual mode

The basic principle is in switching the combination of loops and switches when a MIDI message Program Change, Control Change or Note On is received. But there is even another option. An individual Control Change number can be set for each loop or switch. It is suitable for example when you have some combination of effects and you only want to switch a booster on by single pressing of a button on a foot MIDI controller. This would be possible by switching on a program number with selected combination of effects and switches. But moreover, it is possible to control the loops and switches individually.

If you want to set an individual Control Change for selected loop or switch, press and hold the appropriate button for cca 5 seconds. The display then shortly shows IND. You are in the individual mode for setting Control Change number for selected loop or switch. The default setting is ---, it means none Control Change is assigned. Using the buttons Program↓ and Program↑ set the Control Change number (in range 0 to 127).

If you want to to edit another loop or switch in the individual mode, just press shortly its button.

When you have set the individual Control Changes, press Save button. This configuration is permanently saved then.
