LEPLOOP was designed to be a minimalist electronic music live-performance groove-box, which can be used to create a variety of electronic musical styles. Small in nature but aggressive in sound, the user will be able to create a variety of analog timbres and beats. We are happy to present the third series after ten years of production, with some update: Panel and Box design with Italian design studio IOSAGHINI General PCB Redesign New Metal Shaft Potentiometer New 15v Dc Power Supply On\Off Power Switch Envelope 1\2 Gate in\out Connectors Envelope 1 release CV controllable with LFO or Sequencer VCA 1\2 Linear \ Exponential Switch LFO rate CV In The LEPLOOP can be synched via MIDI to another LEPLOOP for tempo-synched operation or to another MIDI device or sequencer to receive sequence stop & start instructions.

The Bass Drum (CASSA) has it’s own dedicated output,when connected the CASSA volume knobs remain active for the MIX output. Rhythm Sequence There are four rhythm instruments and one capacitor analog sequencer.4 small red LEDs for track playing or analog sequencer mode.16 Led’s bar shows rhythm sequencer and other informations.The maximum length for the analog sequencer is 16 notes. This is a true analog sequencer becausennotes are stored into 16 capacitors switchednby analog multiplexer. The Analog Sequencer This is a true analog sequencer becausennotes are stored into 16 capacitors switchednby analog multiplexer. As the capacitors are subject to discharge, the note pitches will slowly decrease. It’s not possible to store the note value in memory. Thusly, the LEPLOOP has a 16-step analog recorder, much like an analog delay. Over time, as the analog sequencer cycles through its pattern, the signal will degrade and the sound will change. This is because the capacitor can only store the signal for a limited amount of time. The analog sequencer is digitally controlled tempo-wise, and will work in conjunction with the digital track sequencer. Midi Implementation When you turn on the LEPLOOP, default is midi channel 16 for percussive instruments and channel 1 for midi notes, LEPLOOP use two midi channels: the first accepts notes for percussive instruments (4 coloured LEDs), the second is used to play PWM notes.
