I was approached to provide a floppymusic setup for an upcoming show but the issue with my own setup is that it got so many changes over the last years and was never made to be stable that it would never survive shipping.
So i decided to make a new one an fix all the problems the old setup has. Most importantly the drives are now mounted with screws instead of velco and the power supply cables are much more reliable now.
Another important change is the addition of shift registers to enable each drive when playing a note and disable it when unused. This blinks the leds and reduces power consumption a lot when used with external stepper drivers
