There is a significant problem in marrying computer technology with music technology: the latter is going to get left behind at some point.
I play an elderly Ensoniq ASR-10 sampler at church. It's actually only 17 years old, but it is technically a computer designed for playing music so from that aspect ancient. It has a 68000 CPU, 8Mb of RAM (originally, it shipped with 2Mb!) and a HD 3.5" FDD. The SCSI-1 interface was a later add-on. But look at it as a musical instrument and it's got years of life in it, so long as the storage holds out. People continue to resurrect old ZIP drives, ancient SCSI drives (I have one myself) and CF-adapters are also still sought after. I know of people still use SyQuest drives! And floppies are still being used to interact with a PC...
Earlier devices from Ensoniq used DD 3.5" diskettes and they are very rare. I had collected some sixty of them over the years prior to finally selling my EPS-16plus, and sold the diskettes with it. Now I have to stockpile HD diskettes?
