Sounds great Miro! I think there would be a lot of interest out there for Roland S-50, S-330, and S-550 disk creators. Extracting wav files is pretty easy with some of the other editors out there, but the converting, importing, and creation of S-series disks is still pretty much done only with SMFW30. You have a great niche there and I'm hoping you can release an update in the near future, but these old S-Series samplers fade into dust. The HxC Emulator has also been instrumental in keeping the W-30 for example a bit more current. From my experience, I actually find the S-50 to be the most fun to use. It's a bit simpler than the W-30, but what the W-30 has is the sequencer and the ability to convert different formats. All of the S-series samplers are similar but different in their own way.
Keep up the great work and I hope perhaps a new release can rejuvenate the SMFW30 crowd!
Thanks!
