They are advertised as floppy replacement for musical instruments, does anybody know if they work right ?
I don't think so. Note where it says further down:
"Note:This is universal type!! it only can replace the floppy drive that is compatible with PC, We assume our customer could be expert with jump wires"
Most older musical instrument samplers use Schugart configuration floppy disk drives (which are NOT standard PC drives) - their cable wiring is different to a PC floppy drive. If you put a normal PC floppy drive in as a replacement it won't work in most cases. It could even kill your sampler. That product linked there would be a PC drive replacement. Unless the ad actually says that it has been tried and tested successfully on your actual sampler, you have to assume that it may not work.
That's why these emulators are being developed. Otherwise, since day 1 people would have been simply replacing their floppy drives when they wear out with a PC drive, and you wouldn't hear about such emulators (except for storage capacity convenience). You CAN adapt a normal drive to work in some cases but it's a lot of fiddling around (you may need to change the spin speed also) etc. And even then, only certain brands or types of drives will work. I've looked into this with my Casio FZ-1 sampler, which are notorious for having dead floppy drives.
I think in all of these responses people are forgetting that some people really really really like their ASR10's. It's not about "well, for that much money, I could buy a ".......". Maybe. But to the person wanting their ASR10 because they really like it, it's not going to cut. They are looking for ways to keep their ASR10 in use - cost isn't so important as having a working machine that the'yve spent all their years on developing their own sample libraries, banks etc. These are what's valuable. As well as the way the machine sounds, goes about it's tasks, familiarity etc. I completely understand, and feel the same way about my Casio FZ-1; sure it's a crap sampler compared to anything that's available now, or even not available any more; but I like it, I like the way it sounds, I know it and know how to work with it, and I have a large library of my own samples and banks stored on perishable media.
I think Hideaway was messing about trying to get an FZ-1 working with a HXC a while back; I would consider spending money on one of these flexidrives if they worked on my FZ-1, especially if they were more streamlined in use than the HXC.
Just my 2 cent's worth as a fond crappy sampler user
