What's New in Super J8 Synth + AUv3

1.3.2

July 21, 2026

THANKS EVERYONE! This app will just get Better & Better! • FIXED: Long glide/portamento now returns smoothly from the current pitch position when releasing a held note, instead of jumping to the target note first. The other AudioKit synths will also get this fix. Thanks! • IMPROVED: Mono mode behavior has been refined. Mono Legato now more strictly cuts off lingering release tails after keys are released, for a more traditional mono synth response. Mono non-legato still keeps the musical analog-style response where released notes can naturally ring out, useful for Juno-style arp tails and long releases. • UPGRADED: More precise LFOs • NEW: PROGRAM CHANGE MIDI MAPPING You can now use a custom MIDI CC to change presets. Go to the About Page [i], tap “MIDI Mapping,” then “Add/Edit Mapping.” Choose “Program Change,” then enter the CC you want to use. • FIXED: Less stuck notes. If you're still getting stuck notes please feel free to email me directly matthew@audiokitpro.com with as many details as possible so we can get this fixed for you MORE UPDATES COMING: Yes, Microtonality, World Scales, better filter key-tracking and more are coming!

Nothing Like a Real Jupiter

Well, I was sucked in by the very slick marketing from AudioKit saying that this was a Jupiter on iOS. I’m sorry to say that this sounds nothing like a real Jupiter. In fact, it sounds like all of the other AudioKit synthesizers. Not even close to analog. Completely digital sounding. As long as you know these facts, it’s a decent synth. But a Jupiter it is not.

良い出来です

クロスモジュレーションの音が美しいです。リリースしてくれてありがとう。

Thank you, thank you, thank you!

Wow, what an amazing Jup 8 you have provided to us on iOS. The price is ridiculously low. I own everything you offer and have written reviews before. This one is my favorite by far. However, all are so creatively made to serve a variety of purposes. You’re the best of the best by any measure of creating synthesizers I can play on my iPad. Just remarkable presets! So much fun!!

Update

Thanks for improving Keytrack. Now if you could do the same for J6 would very appreciated *prays*

Just buy it!

This sounds so, so good! Easy to dial in sounds but so tweakable. Look out for the Pro-A5 as well - it’s an absolute beast! To say AudioKit have really upped their game is an understatement…
