Luci x256 BPM
256 Fireflies network
This is an extension of Luci x64 to 256 elements. Syncable to BPM thanks to Kimmo Kivelä. CPU-power hungry (with sampling rate at 32kHz, 37% on an eight 3GHz intel processors machine).
Extended frequency range when synched to Hz... as usual, frequencies above 10Hz make display unresponsive.
