Being pretty skint when it comes to affording plug-ins, it's neat that companies can release fully functional freeware as a taste of what their commercial products sound like - and reFX has something special with Claw.
It may be pretty basic in its synth architecture - it's only got one oscillator, and it's monophonic - but it's got some nice delay and distortion functions to fatten up the tone, and the gui features a nice retro knob look. And the basic sound is pretty warm for digital, with a nice high end for cutting through a mix.
But IMHO one thing that's really neat about Claw is how well it gets along with input from MIDI guitar signals - it even tracks better with my "ancient" Roland GM-70 than most hardware synths. If you're a guitar-head who wants to input synth lines with MIDI guitar in your compos, this VSTi is certainly one of the best tools to keep in your virtual kitRead Review
