Amazing!!

I love this app so much! I’ve only used it for about an hour now, but I love the flexibility and lfo routing options - the interface is easy to use and quick which is so important when you’re trying to make music (less time fiddling, more time playing)

I wish the envelope attack could be increased beyond 2 seconds for bigger pads sounds, but I can’t bring myself to give less than 5 stars for this. Thanks for a great app.

Crashes

App will crash after going thru a couple presets. I just bought this, please update or refund please

A beauty

Capable of producing really out there, mesmerising, otherworldly sounds if you take your time with Phosphor 3. I can imagine it’s not to everyone’s tastes but if it is then there is nothing else like it. One of my favourite synths to use in almost every project, both in iOS and desktop.

Capable and Amazing!

I don’t know how long I’ve owned this synth but I just got around to playing it and wow, it’s fun! It has a unique feature which I’ve only seen on Copperhead by 4Pockets; it allows you to design your wave by setting the fundamentals! This is a big deal. You can learn a lot about audio waves just by observing the effect the fundamentals have in the wave shape.
Too bad there’s no oscilloscope to show the effect but there’s several on the App Store you can attach to via your DAW via auV3.
This is a great synth… just get it!!

Frequent crashes when rotating presets

After running through a number of presets, this synth will crash. I’ve been able to replicate this bug 4 times in the last 10 minutes of trying it out.

Edit: This bug may have been patched. There was a recent update but no update log. Before the app would crash at about 20-30 patch cycling. Now it's more like 100-150 when changing patches very quickly. Thank you.
