This is now our most popular Band Organ. It provides MIDI compatibility with the original arrangements of antique Carousel Organs. Really a nice unit. This is similar to the BW66 but It contains 38 Calliope pipes, Bass Synth, 12 glockenspiel bars, 41 note Accordion, Bass Drum, Snare Drum, Tambourine, Triangle and Cymbal. The 12 note Glock actually provides more action than the 24 note since we reroute all the notes to the upper 12 bars. Then they are playing twice as often and the higher notes are more delightful and the cost is less! Fantastic music. View on Ebay!
