Features:
Hand-made True Bypass Box - MIDI Looper4
Dimensions (width x depth x height): 210x80x40 mm = 8.3x3.2x1.6"
4 True Bypass loops of effects divided in 3 sections (2-1-1) with isolated grounding for channel switching
Sockets:
MIDI IN
MIDI THRU
3xInput
3xOutput
4xSend
4xReturn
9V DC input
control by the Program Change (1-128 or 0-127) and Control Change messages on any MIDI channel (1-16)
3-digit LED display (with the on/off option), LED status indicators for the loops
full programmability
MIDI IN and MIDI Thru socket (which strengths the signal allowing a connection of any number of the MIDI-controlled devices)
high-quality parts including relays with gold plated contacts, Neutrik sockets
powered from the adapter of 9V DC and 200 mA with the coaxial type of plug 5.5/2.1 mm and "-" on the center pin
powder-painted aluminum housing in blue colour (the same as WOBO MIDI Looper) with the white overprint including a short manual of programming the unit, anodized, scratch-proof side panels and front plate with the LED display and programming buttons
if the power fails, the unit switches into the Bypass Mode - you will still be able to play the guitar and hear its sound
The WOBO MIDI Looper4 turns a set of pedals (or other effects) that cannot read MIDI messages into a fully working remote setup that can be controlled by any MIDI controller or sequencer. This includes guitar amplifiers in which the channel switching is done by standard latching footswitches. The WOBO MIDI Looper replaces the footswitch and lets you control a non-MIDI amplifier with your MIDI setup.
The WOBO MIDI Looper4 is specially designed for True Bypass switching of effects through MIDI data. Thanks to the gold contacts used in the relays designed specially for this purpose, there is absolutely no impact on your sound. The configuration of the inputs and outputs extends the use of the looper, which can also be used as an A/B/C/D switcher for choosing either the signal receiver (e.g., between the amplifiers) or the signal source (e.g., between different instruments). Using the WOBO MIDI Looper you can switch the amplifier channels by means of the send or output sockets of loops 3 and 4 connected to the “footswitch” sockets of the amp. The MIDI Looper replaces the standard latching footswitch.
The actions of the WOBO MIDI Looper are controlled by MIDI messages received via the MIDI socket. The MIDI Looper can receive "Program Change" or "Control Change" message on any pre-defined MIDI channel. Programming is very easy – you only need to select the "on"/"off" state of the fx loop for the last 'Program Change" message received. The 3-digit LED display allows you to check the channel number on which the last "Program Change" message was received and which MIDI channel has been chosen for the reception of the "PC" message.
The unit reacts to the "Control Change" messages 71, 72, 73 and 74.
Thanks to the unique design of the "MIDI Thru" socket circuit the unit makes received signal stronger and you can connect any number of MIDI Loopers or other MIDI controlled devices, cascaded after our unit.
Due to the high power consumption by the relays (approx. 160mA), the MIDI Looper cannot be battery powered. But this is not a problem since you can power the unit from your pedalboard's power supply. Recommended power supply is of 9V DC and 200 mA, with coaxial type of plug of 5.5/2.1 and negative center pin. If the power fails, the unit switches into the Bypass Mode - you will still be able to play the guitar and hear its sound.
