Hi. Is there a problem with your Roland? Or just the floppy drive?
Can you tell me the town you live in (i will try to find the nearest to you). I was asking about the problem because there is now floppy emulators flash based can can replace old floppy and are lot more reliable.
All what we talk about here as long as it is related count as one question for me. I don't know either the file format. Perhaps if we could mount the disk (let say it si simple fat32) we may try to play files in VLC or a midi/MOD player.
As for the floppy emulator, those are hardware replacement going into the keyboard. They are usually not that expensive and you should be able to use a disk image on them (not needing to know the disk structure). You can probably write the image of that floppy with DD or RawWrite.
I will check later if i can find someone near you that might able to do what you want.
Here is a video overview of how the floppy emulator replacement work with the W-30:
Here is 3 places that might be able to help. It depend if they have in store a W-30 or something close enough to extract the data or know a good customer that may be able to help. Other than that there is always the possibility to contact an owner on youtube and manage to have them make the mp3 (that part is easy once you have a working W-30).
In fact, if they even just have a floppy emulator and you can bring the keyboard, it make it also possible.
I can try to contact Jim Atwood (the guy in the video i linked). It may take a little time that said before he answer back. I am sure he can do it, does he have the time, for that we need to contact him to know for sure. He sure have all the hardware to do that. You would only have to email him an image disk of the floppy and he could email you back the mp3. So, this is your call. In case you want to contact him directly to speed things, you can get to him from his youtube channel or by email at***@******.***
The best is to not send a floppy by mail, just to send an image disk by email. That way it won't be damaged by a metal detector.
You can't put a floppy in an emulator, only an image disc. You create surch an image disc with a computer with a floppy drive and someting like raread (i am not sure if we can also create one with rawrite), dd or winimage.
If jim did not answer you, he have no more chance to answer me. That said he is not alone with a W-30 i guess, so you may ask on synth forum for someone with one and a floppy emulator.
You can request a refund of the deposit. In that time i will opt out of the question hoping someone here have a W-30, if the moderators would put your question in the general category it would increase the chance greatly.
