I made long tests lately, comparing the synths and FX I own / freeware and categorized them good and bad.
Here's the good list.
Commercial:Synth:
Iris 2
UVI Falcon (Sampler and mother of all synths)
Air Loom (best out of the old package that is constantly on sale)
FX:
Neutron
Valhalla Vintage Verb
BT Stereo Imager
BT Tempo Delay
BT Valve Drive
LP EQ and MB Comp
Adaptive Limiter
Free / Gimmick:Synth:
TyrellN6 and BazilleCM (get those! They are free resp. cost you one issue of CM Magazine. They sound as good as Repro-1 one, just make yourself and FX chain like Repro-1 has, Waveshaper, Drive, Resonant filter, Delay, Reverb)
TAL NoiseMaker
FX:
MWaveShaper
MStereoScope
SGA1566
HY Filter 2 Free
ReverberateCM
IVGI2
TDR VOS SlickEQ
OrilRiver (use it as send effect ;) beware, latest beta version seems a bit buggy)
HY-MBMFX, great multiband Spatial / Stereo Width adjustment
EDIT: Updated list with the ones I forgot.
MiniFilter V (giveaway a while ago)
TAL Reverb II
Transpire (giveaway a while ago)
Took me
days actually month, when I think about it, to compile this collection, it's not just random stuff.
Hope it helps!
