MIDIGEN – A (belated) LEMS postscript

This short article discusses an add-on to the following:

The Brute: A 3-channel Audio Amplifier For Leslie Speaker Emulation.
Treslie: 3-Phase Leslie Speaker System.
LEM: Leslie Emulation Control System using PIC Microcontroller (18F26K20) based on Pequeno board, (Arduino-alike) and 3 DACs.

Shortly after completing LEMS, The Brute and Treslie, (see links above) it became apparent to me, that [...]
