Excellent synth!

Love it! Very well thought out synth. Not as complicated as you might think on first glance. Lot’s of options, yes, but they all make sense easily. Lots of sound possibilities. I mostly prefer sounds that can be played on a keyboard, and there’s plenty of possibilities for this. I have most of the top synths, and this one definitely doesn’t duplicate anything and stands out on it’s own.

Saw couple of reviews on font size and NanoStudio support. Fonts look good now, and for NanoStudio to see the AUv3, after installing the app I just restarted the iPad and it showed up. No crashes or glitches in standalone or plugin mode after several hours of continuous use.

Definitely recommend this synth. Although you might need the Apple Pencil to use the Harmonics, they’re just too tiny for fingers at the moment.

Some requests:
Please change the knobs to behave like sliders as opposed to the rotation gestures. It just doesn’t work right. Some apps give an option to change between the two but I don’t think anyone would complain if you just change the gesture to fader-style only ;)

And another suggestion is, please make the Harmonics expandable. It’s the central point of the whole sound engine so it needs good precision and ease of use. I have a 12.9” iPad, and it really needs the use of Pencil to get it right (the width of my finger covers two harmonics fully).

Inspiring instrument!

A lot of iOS/iPadOS instruments I’ve purchased feel a bit like toys. This one immediately joins the ranks of the few that feel like, and have, the utility of real instruments.
Some really fantastic sounds can be achieved and experimentation really pays off. Good job with presets, by the way. They do a good job of giving a sense of the possibilities.
I agree with some of the other comments about the interface: it would be nice to see even more use made of the touch interface wherever possible, and the smaller text and size of the items in the preset lists can negatively affect read/tapability. I also found some of the rotary knobs to be a little fiddly, but I’m getting the hang of them. Might be nice to be able to double-tap to zero things too.
However, none of these things is standing in the way of my enjoying this wonderful instrument. It’s really something already, and it’s just been released!
I’ll be looking forward to whatever refinements come over time. In the meantime, I’ll just be busy making music with it. 🍻

I’m in heaven!

Finally, after all these years, an iPad synth that is as interesting, inspiring, and as much fun to program and play as my hardware Buchla 200e setup. The developer has kept it real and was not seduced by all the possible and unnecessary bells and whistles a touchscreen can bring. Every layer of this dream machine is well thought out, allowing the user to go as fast or as deep as they want.

I thought my old eyes would have trouble with how dark the coloring is, but after hours of looking at it, I was thankful for how easy it is in the eyes. And the sound quality is excellent! I’m looking forward to putting together any array of midi controllers to make it a playable, physical instrument.

Ah, I just thought of an improvement. There is already excellent stereo panning control. The possibility of having four outputs with circular spatialization would be a fitting tribute to Don. (Probably a bit too much to ask for at this point.)
