RaSCSI and Open Source
The SamplerZone RaSCSI
Specifically defined, RaSCSI is a SCSI daughterboard that mounts on the 40-pin header of a Raspberry Pi, plus the service app that runs it on the Pi itself. What SamplerZone calls "RaSCSI", it is the full working "drive"; that is, the RaSCSI daughterboard, the Raspberry Pi, within a professionally designed case and with the data and software fully set up so you can simply plug it into your sampler and it'll work. Instructions on changing outs images is supplied with the product.
History of RaSCSI
RaSCSI was not pioneered or invented by SamplerZone. It was invented by "GIMONS", a guy in Japan, back in 2017. Most SCSI projects are targeted toward old Mac systems, as that is a huge boutique market. Even SCSI2SD is mostly targeted worldwide to SCSI computers like the Mac and Amiga's. For instance, a popular reseller of SCSI2SD is AmigaKit in England.
Around 2020, a inventive guy named Tony Kuker in the United States picked up the project and did some finishing work where it was a whole lot more reliable. The current code is centered at his GitHib repository.
RaSCSI technology is covered under Open Source BSD (Berkeley Software Distribution) 3-Clause. This pretty much means it can be distributed as-is but if you make changes, you must have specific and explicit permission.
There has been some confusion and misinformation, propagated by a collection of enthusiasts, about SamplerZone's distribution of RaSCSI. This article aims to correct that.
