Crisp looking, compact little 2 osc VA unit with a sweet spot which is quite easy to get into. It's hard to explain, but this synth can sound mediocre, almost lacking in power at first, but after a bit of tweaking, it gets into it's groove, what I call it's 'sweet spot', and it begins to sound very juicy and powerful.

The two oscillators each consist of two waveforms with selectable octave, which can be blended together for each osc. Then you blend osc 1 and 2 together, adding ringmod, AM, overdrive, filter FM, noise, and standard filter action. There are *around* 30 waveforms, so quite a bit of a choice, but some of them are a bit samey, and I'm fairly sure a couple are all but duplicates. That aside, with the large palette and plenty of wave mangling options, there is plenty to choose from.

The real power core of this synth is it's seven slot modulation matrix. Here you can add constant values or controller/envelope access to any parameter. This is where you, for example, set osc 2 to play a harmonic interval (there is no knob for it) or perform PWM (wave stretching works on all waveforms). This, combined with the three LFO's, two envelopes and controllers, is what brings the sounds to life.

Consider one patch I made, there are two waveforms, 'combed' together using AM to make a raspy tone. As you move the modulation wheel, a resonant lowpass filter closes, and the two oscillators drift out of tune, one up and one down, creating an 'in and out of focus' type of sweep. I had plenty of slots left over to add octave stretching (so higher notes are slightly sharp) and aftertouch based vibrato... This is the sort of flexibility the matrix affords you.

Since you can do PWM on any wave, you can mix two waves in an oscillator, one several octaves above the other, and perform PWM. Because one cycle of the base wave contains several cycles of the higher wave, and the waveform is stretched from the midpoint and as a whole, you can get a swirling harmonic wave effect which is a good stand-in for sync (it actually sounds like a sync which is both rising and falling at the same time!). PWM on other waves will make similar swirling harmonics or thickening effects, depending on the waveform.

The filter is on the calmer end of the scale, but in a very musical way. Filter FM is the standout feature here - it simply sounds gorgeous, and can add anything from a subtle textured distortion, to full on formant effects, as the FM amount can be a modulation target, and can be sourced from any waveform from the two oscs or the noise section.

GUI-wise, I think it's fine. Silver and blue create a distinctive but mellow visual experience, and everything is neatly laid out, with nice knobs.

Overall, a flexible workhorse for bread+butter sounds and beyond, which takes up little CPU power and rewards your creativity with an easy to hit sonic sweet spot.


After a few months with this synth I've noticed that like a lot of VSTI's, it can generate a fair bit of DC offset, especially if you use the Osc Symmetry parameter. I'd recommend using a good highpass filter or DC offset remover directly after it in the signal chain.
