i used to be secretly v down on synthedit-made things - not so long ago it felt like kvr was spammed daily with A+B synths and 303 clones with *funky* front panels that glitched or crashed at the first chance they got - but lately i've changed my mind. maybe it's just faster CPUs and better SE releases, but i don't tick the 'no synthedit' search box anymore and this odd, neat little synth is one of the reasons why.
the interface is entirely unlabelled and unexplained, but the sound of the presets hooked me enough to stick with it for the 60 seconds it takes to figure out what's what.
so, yeah, it's a harmonic additive synth, with a global pitch control (new users: the LH one of the 3 sliders on the right), a slider for each of very many harmonics, and an ultra-simple and very intuitive graphical ADSR for which some kudos is due. no phat bass here, but great for weird steam organ/water drop/imaginary sci-fi flute sounds and potential far beyond.
i could wish that the pitch control was calibrated, it's a too-short slider and a PITA to tune sometimes, and i could wish for some way to evolve sounds as they play. but then what's neat about this is that it's a shortcut to find sounds that many other, deeper synths can also do, but make more difficult and less fun.
