Does the world need another basic 2 or 3 oscillator virtual analog? After trying IBlit, I think maybe not. It sounds very nice, with a sound that is clear. But, it seems to lack character compared to Triangle or Synth1, even though it has an extra oscillator compared to those. It lacks features, including effects a, variety of waveforms, sync, apeggiator, and so on, so maybe that's the difference, but in any case, I wouldn't use it for leads or pads.
The documentation is basic, but what do you need to know about a simple VA synth? The GUI would work better if it was more compact, it takes up too much screen space for what it does. The presets are nice, but nothing you haven't heard before.
In summary it is very nice for what it is, a very simple VA synth without aliasing, but it isn't in the same class as Triangle or Synth1.
This is quite a good synth. The GUI looks good, but after a while I tired of the knobs. I find the sliders of the JX16 to be a bit friendlier. And, the punch of the JX16 seems to be missing, but it still sounds great for leads since the built-in effects really add to the depth of the sound.
