I used SCL to XRNI to tune my instruments in a microtonal scale I developed over the last years. In modern western music the octave is divided into 12 equal steps. My tuning divides 2 octaves into 33 equal steps. This means that only every second octave is in tune (you will notice that by listening to my track). More info about my tuning can be found at Equivocal Tuning
So enjoy and good look to everyone!
