LP2 Gen D mini looper

The LP2 mini looper offers 1-41 stereo tracks for looping.  The LP2 is a less powerful version of the 
LP1 Gen B looper.  Many of the features of the LP1 are accessible through MIDI commands.  The 
audio interfaces is identical to the LP1 Gen B audio interface.  Audio is sampled with a sample rate of 
48 kHz and 24-bits per sample.  Audio is stored internally in 128MB of RAM and at least 16GB of 
microSD.  Like the LP1, currently recording and playing audio is stored in RAM.  Tracks are saved to 
persistent (microSD) storage in the background while the audio continues to play.

FEEDBACK

The FEEDBACK input takes a ¼” TRS plug from an expression pedal.  This controls 
the feedback setting of the current track.  100% means that the track will loop 
indefinitely.  Anything less than 100% and the track will fade each time it plays.

CONFIG

The CONFIG button is used to select configuration or setup mode.  A short press selects 
configuration mode.  A long press selects setup mode.

SDCARD

The SDCARD slot is not used in the current generation LP2.

MIDI OUT

The MIDI OUT connector provides MIDI clock to other devices and provides 
Looperlative SYSEX messages for status of the device.

MIDI IN

The MIDI IN connector allows external clock and control to the LP2.  Firmware 
upgrades can also be provided through this port as MIDI SYSEX files.

POWER

This is a 9V 1A negative-center power input.

IN

This is a ¼” TRS socket that accepts stereo audio input.  You may connect a TS mono 
cable, but then only one of the two channels will be used.

OUT

This is a ¼” TRS socket that provides stereo audio output.  You may connect a TS mono
cable, but then only one of the two channels will be used.

MIX

This knob controls the amount of dry signal that is passed through the LP2 from input to
output.
