Another 'vintage' VSTi which still sounds good today. Claw, being free and sounding as good as it does, deserves to be in every computer musician's arsenal. While it is capable of bass and acid-like lines, I find it lends it's self most of all to sleazy leads, backing synthlines, and the odd outlandish effect.
The one oscillator offers (and crossfades between) the usual square and sawtooth, but also a triangle wave. The waveforms are not 'drawn with a ruler' accurate in shape, and that's a Good Thing, especially in the case of the triangle. This is one of the most usable, sonorous triangles I've heard this side of the Minimoog triangle wave, and just begs to soar in the high range with a bit of portamento and the filter digging in to it's harmonics.
PWM is available on both the square and sawtooth waveforms (on the sawtooth, it cuts a variable-sized hole in the middle of the ramp of the wave, creating rich sweeping harmonics.
The filter is sweet sounding, and in conjunction with the very nice overdrive dial, creates a wide range of sonic possibilities for a single osc synth. The filter also has a highpass mode, which is a generous addition.
The overall sound is very solid and professional. It sounds like a real monosynth, and lends a certain 'coolness' to the tracks I've used it in.
Overall, an unmissable freeware synth for cutting synth lines.
