I did consider a TX16Wx version last year when doing the alternative versions. If I remember correctly, I even did one version using ConverWithMoss, which was extremely helpful when creating the DecentSampler version. Unfortunately, it wasn’t very stable and had some annoying mapping errors. I like the idea of having a free versatile multi-sample capable plugin like the TX16Wx, but whenever I’ve been trying to dig into it I’ve given up; the stability on my system is not very good, and the GUI for sample pack creation feels a bit clunky. But maybe one day…
I do have some other plans though: a friend of mine has got a tiny Kawai (might be pianetto size, can’t remember now) that’s being tuned some time this month. We have discussed sampling it.
