What's the aim in terms of quality and application?

We haven't tried to make the BEST sampler, but the general benchmark we had in mind was that it should sound at least as good as a Techno Sound Turbo, and hopefully a little better. Lower/mid-range samplers like the GVP DSS8+ incorporated preamp circuits and ADCs with allegedly better SNR performance, and while we haven't the information or the means to clone these directly, we are implementing a filter and preamp circuit of our own to hopefully improve SNR. Higher-end samplers, as discussed earlier, use various port tricks to achieve higher bitrates and (on accelerated Amigas) higher sample rates but they're often operating outside the ability of a stock Amiga to replay those samples usefully.

Our benchmark in terms of application, or what it should be possible to use this sampler for, is that it should work with most versions of Protracker, OctaMED, and similar trackers. Working with popular audio packages such as Audiomaster II and even some of the software that came bundled with the original commercial samplers, now largely in the public domain, is a bonus - but usually cheap samplers will work in most of these apps when treated as generic sampling devices and so should ours. Typically if a sampler-specific app has an option for controlling a special feature of that app, it'll use the PAPER_OUT and SELECT pins of the Amiga's parallel port to send custom messages and these will usually be ignored by a third-party sampler such as ours. So far, compatibility is high - but again, trackers are the critical use case and anything else is a bonus.
