DimPro preset abbreviations

What does 1v, 3v, 4th, m3, rt, rt sim, etc. mean on the piano preset names?

OK, "rt" stands for Release Trigger: that click noise that happens when you release keys on an acoustic piano. Anything with "sim' in it uses a Body/Damper simulation to kick in some string vibration sounds with the sustain pedal. What do they call that: half-pedaling? You know what I mean: your hands have the keys pressed; opening them up for other notes to start them vibrating. These add some resource overhead to the programs, but also add a level of realism. Combinations use both.

From here out, it's educated guessing. 1v and 3v indicate the number of velocity levels that a piano preset uses. I always thought that "m3" and "4th" refer to the distance between samples used in the program. m3 may stand for a minor third, but then 4th? It's not a perfect fourth, but it does appear that these program samples are spaced 4 keys apart. Here's the thing, though: the .sfz files point to every third or fourth key, but it looks to me like an entire 88-key piano was sampled.

Check out all of those "unused" piano samples. No doubt it's a good compromise to span several keys, tune ranges within the .sfz file, and keep the memory requirements down. But I see no reason that you couldn't easily construct a massive piano out of these, keeping in mind that it's going to top a gig or more in memory.

I'd say that BT marks the programs that Nico Herz of Bigtone did for Pentagon. He did do some electronica work for Dimension Pro.
