Ive had Peach and most other Tweakbench vsti on my hdd for years, sitting there waiting for me to rescue her, but sadly my princess was in another castle. By which I mean, other instruments drew my interest.
Then one day I pulled up the princess of mushrooms, and really listened to her sing. She sang a Zelda dungeon melody that became the basis for one of my best tracks, all of a sudden! :D Then it became apparent that the ol' Floating Lady had some real pipes :P.
I admit that I prejudged her for her wavetables; I'd previously delegated them to second-class status, unfairly, for their inherent sound-control limitation. But Ive come to believe that working inside set parameters, with set-in-wave sounds, inspires in its own way. Esquisite Corpse can breed more interesting images than a blank canvas :P
Its important to note that the NES and its sounds shaped who I am, without games like Zelda and Dragon Quest I don't know if I would have the imagination I do now, so I am a biased reviewer, I admit :P Because Peach brings back the memories...
GUI-10/10, simplify simplify, dont need more than an ADSR, pan and volume, the crunch is icing on the cake.
Sound-10/10 its got all the nostalgia-induction I ever wanted
Features- 9/10 I docked a point, just because it would be nice to be able to add more wavesets, but the ones it has are pretty much the whole kit and kaboodle
Documentation- um im gonna leave that one blank, it doesnt really NEED documentation and the publisher site provides what little may be necessary
Presets- 10/10 sorta, cuz it doesnt really have presets, but the wavesets are plenty
Customer Support 10/10 cuz Tweakbench, ehs a real cool guy and doesnt afraid of anything (and seems like a good person, one who deserves a beer on me)
Value of course 10, and stability 10/10 just like ALL TB plugs, the thing is rock solid and hasnt so much as hinted at a crackle.
Ive found myself using Peach more and more, in fact in my recent work Harmonica I was having trouble finding a good lead instrument, and went through all my commercial vstis (spent 6 hrs just on Surge to no avail)... Then for $#!ts and giggles I loaded up Peach, and she fit like she was made for it. Id link but thats html and it would be removed, if you want to hear my work with Peach visit my soundcloud, its slash-mudpeople or find me on the forum, its in my signature.
Tweakbench FOREVER, long live the mushroom king!
Honestly, there are probably equally capable chip-sound vst's/au's available by now. Windows traditionally has more of these small, free (usually Synthedit-made) instruments and effects, but I'm sure you can find what you're after for Mac as well.
Plogue Chipsounds comes to mind, have you looked into that? From what I remember from the demo, it's an impressive instrument for chiptunes, although I'm not sure anymore if it covers NES specifically.
