reFX quadraSID is a fun and unique synth. It takes a little more effort to program it from scratch than some, maybe due to the fact that you are programming an old chipset with unique attributes rather than programming a traditional subtractive analog, but if you're looking for a hybrid between "that old school sound" and sounds that most other "modern" synths can't make easily (or at all), this is a great choice. If you think you're in for only the cheepo "old school" Commodore 64 sound, then you're selling yourself (and quadraSID) short. It does more than just make classic cheese! (though the classic cheese is certainly there if you want it)
The UI is great (especially this new one). If i had to complain, it would be that the unison mode is a bit clumsy to audition the 1/2/3 unison presets. i also think that the behavior of the note triggering is inconsistent but this may be an inherent aspect of SIDs (i wouldn't know). Other than that, add some of your own reverb/chorus/delay effects and this is a cool little VST synth that's light on CPU use and a GREAT price/value ratio, especially with reFX's holiday discount.
