LILLA is a 16bit/44.1KHz polyphonic, multitimbral and multi-midi audio sampler based on Teensy 4.1 microcontroller.

LILLA plays imported audio files, recorded audio, and live audio stream, combining sounds with layering, applying various playing mode, adding ADSR envelope, changing length and pitch, and using digital effects (24dB/oct LPF, per-voice VCF+LFOs, stereo delay).

Audio files (raw format, 16bit 44.1KHz mono files) can be imported using a micro-SD card (not included) accessible via the USB plug, also used for powering the unit. The stereo analog input can be used for sampling (audio recording) and live sampling; audio source can be a line-level audio output or a dynamic stereo microphone. Recorded files can be exported to the micro SD card (raw format).

LILLA internally stores Sound setups (audio file name, ADSR and VCF+LFO parameters, start/end points, play mode etc.) and Patches (a group of Sounds distributed among midi channels and mapped on midi notes) created by the user, and also allows to import/export them from/to the micro-SD card.

Story album

LILLA has been developed from scratch, starting from a small circuit in 2018, equipped with Teensy 3.6 board.

A first "concept" device was presented at Torino "Soundmit", 2019 edition.

This "naked" LILLA realized in 2020 and equipped with Teensy 4.1 was reproduced in few pieces.
