firmware (beta version) for LILLA 2024/2025

BEFORE CHANGING FIRMWARE PLEASE BACKUP YOUR PATCHES AND CONFIGURATION WITH SETUP → EXPORT CONFIGURATION TO /LILLASET/lillaold.txt

This firmware adds the following features:

1. midi loops can be saved on micro SD: a loop can be now saved, saved as new, deleted. Loops are named with a number (0 to 999);
2. patches associated delay settings are automatically saved on micro SD;
3. new key-step option: define the interval between adjacent keys from 1/8^th to 1 semitone;
4. faster and more accurate LEDs control;

The new midi loop saving feature requires some mods of the silkscreen prints as shown here:

ALL START/STOP has been moved up, and a new LOOP command (allows to select and open a loop saved into the micro SD) has been added.
