Well top 10 in order of most used....if i even use 10 regularly...
1. Nexus (go to ROMpler i fire up first tbh, with the expansions (orchestra, analogue, dance vol 1, psytrance, house, bigtone, hardstyle, guitars, perpetual motion, store and forward, and stratosphere) and turning off the delay/reverb and using my own it has everything i need..
2.
4Front Truepianos (go too for pianos)
3. Miroslav Philharmonik (more choice and more realstic feel with some e'qing than some nexus orchestra instruments)
4. Alchemy (enough said..its a monster)
5. Kontakt 3 (bread and butter sounds...especially with sample packs..including some suprisingly decent Motif, Fantom and the Typhoon soundsets from typhoonsounds that got a good review on here)
6. Rapture (hell of a program...)
7. Hypersonic 2 (bread and butter..legendary VSTi)
after that it's a free-for-all of paid for and free synths/VSTis that once i improve my synth programming i'll only need a couple of them..just dont have time to perfect it..
Proteus VX, Albino 3, Synth 1, Tassman 4,
Tone 2 Firebird, z3ta+, Vanguard, Pro53, impOSCar, Superwave P8, all the DSK freebies (Brass, Pianos, etc) Glitch, Crystal, Rez...
and thats not even including FL 9 VSTis which can hold their own...Sytrus, Sawer, Poizone, Biohazard, Ogun and Directwave sample packs..
seems like too much really...and i still want some east west stuff, omnisphere, trillian, nexus 2, reaktor 5, massive,
absynth 5...too many VSTis..
