Presets goldmine

My lasting impressions of this app are that of simplicity and ease of use combined with the ability to dig deep and form your own pleasantries or insanities, whichever you desire or something in between.

If you are looking for something that requires only the touch of a few buttons for a quick sound that requires little or no parameter cracking, like a Yamaha or Casio off the shelf gadget + extras, then your only time consuming part of using the app is making a decision on which of the multitude of presets you are going to use.

Otherwise you can shape and form parameters with all of the familiar names in a different looking interface to your heart’s content until you get it where you want it. That being said, the interface makes more sense on some levels than others, but it is nice to see a developer go beyond fake knobs and buttons in and toward something that leaves the old ways behind while maintaining the same sense of analog fatness (that could honestly be a litter fatter).

Sophistication with the live performance in mind

This one is a REAL gem. Yonac nailed it again; only more so and then some. They’ve managed to create a very sophisticated multi-Timbral synth here and as I’m sure some of you can imagine, one might worry about running the risk of losing hours and hours trying to in program patches among endless possibilities...after all even the most creative among us have lives to live. However, I have to say, for what and how much this synth is designed to do, the U/I is quick and easy to get comfortable with. Maximum functionality/ minimal navigation... and designed for live performance (which I love). The only change I’d make?... I would include amongst the 3 arpeggiator modes one where you could program the pattern/ or maybe include a sequencer just like Magellan’s. A big plus for me is that within the Oscillator module, one can choose from not only simple waveforms, but also a variety of complex as well.

Very (very) Deep

It’s hard to say enough about this synth. I’m not going to repeat all that’s in the description but I believe it’s all accurate. In a way, it’s a testimony to how powerful a platform iOS has become because this Synth is immensely capable. Three true independent oscillations per layer (and they’re really synths of their own, not layers) with Omni stackable effects gives you extraordinary sound shaping possibilities. Ok, I said I wasn’t going to repeat the description and I just did. But I can’t imagine a hardware synth being able to do this so simply (I have a Moog One and this can produce sounds that easily rival it - and that synth cost me $8,000).
I’m sure I just said something heretical but it, true. Buy this synth and save yourself a ton of money!
