WaveOSC

Well, it's true that this is re-made old Union synth. But it has fixed serious bug that made Union unreliable on Windows (don't want to describe it longer, it's not opinion about Union after all). WaveOSC (Union too btw) sounds warm and nice, it has its own character. Few options are missing - unable to connect velocity to anythng but volume and no modwheel support. But every synth is different and I guess this one may be a nice starting point for anyone who wants to create interesting sounds.

Problem with WaveOSC is that for some reason (money?) they created it the way so old presets from Union cannot be loaded (even if format is ALMOST the same and it's probably just intentional to block that possibility). Second problem is that it's just made like "we make this synth and that's all". No updates, no new functions, no plans for development, nothing.

So 3 stars, because it can sounds nice, is not complicated and it works ok. And can be bought for a small amount of $.
