Legato Sustains
These are legato patches with up to six dynamics. When I say six dynamics (in this instance), that is on all assets, not just sustains. So six dynamics on legatos, same-note repetitions, sustains, etc. In other words, it's all balanced, not sharing 1-2 dynamics of intervals amongst more dynamically sampled sustains.
Same-note reps trigger when holding down the sustain pedal.
Staccatos / Staccatissimos
These patches consist of three different assets: attacks and two speeds of same-note repetitions. So there are “sympathetic-resonance” attack samples which are notes coming from another pitch. Then, when you settle on one pitch and repeat it, it starts to trigger in the first rep speed. These are repeating samples recorded on one pitch. Play faster and it triggers in the second rep speed (faster repeating samples recorded on one pitch). So you're not really restricted by speed.
Flutter Tongue
These are flutter tongue patches with attacks that are "coming from" another pitch. These patches are dynamic.
Playable Trills - Multiple Tempi
Built from actual recorded trills, these are polyphonic multi-samples, and you can play trills (not just m2/M2) and run-type passages with them. The runs in Grasslands Ballet use the flutes a2 playable trills 160 patch. It's also useful to play with the decay setting to reduce the tail.
Don't be overly concerned about the listed tempi. These generally sound good at or slightly below their recorded tempo and up, but they can be used creatively as well for runs. Between the different recorded tempi, you have some flexibility.
Sfz Decrescendos
Accented sfz that tapers off shortly after. The attacks are "sympathetic-resonance" and come from another pitch, and I have the musicians build up energy to the sfz. So they're building up in volume to the sfz to give it more accent, then tapering out.
Think of these like marcatos. I've actually been finding that marking sfz instead of marc gets more of what one would expect marc to sound like. These have multiple speeds of releases so you have length flexibility from super short to long.
By the way, I came up with this on the Vista II brass sessions so that's where it originated (early example). These sfz decrescendo patches will work perfectly with the ones I did for brass. They were recorded at the same tempo, etc.
Sfz Marcatos
Same type of thing but instead of tapering off, it loops. These are wholly separate recordings from the Sfz Decrescendos, so you can double them without worrying about phasing. Same release flexibility as well with the multiple speeds of releases triggering in based on note length.
Tenutos
Short (well, medium-length) held notes, again with the notes coming from another pitch for more spontaneity.
Fast Sostenuto Reps
Rather experimental. They're like fast measured tremolos for flutes.
While the aforementioned stacc/staccmo. patches have the faster rep speed which can get really fast, it was still a “short” marking and not explicitly connected/sostenuto, whereas these are performed connected and held their full length even though they're short. So it's like a connected fast repeated note, rather than a more detached fast repeated note.
Arpeggio/Meas. Trill Experimental Patch
Still in the experimental stage but basically a polyphonic patch that you can play different speeds of arpeggios or trills with.
