Add support for MacOS

This synth is great, but no support for MacOS. Will be support on MacOS ?

Sooooo Awesome

I don’t normally do softsynth reviews unless they’re stellar, and Super J8 absolutely is. It sounds rich, clean, clear and is really easy to use. I own 25 softsynths and this is my second favorite next to Animoog Z.

One of the BEST synths on IOS! A Powerhouse packed in a workhorse!

This is a total “Tank” this thing just wrecks other IOS synths, and doesn’t think about it! Way back when AudioKit came out, I got bought their very first release, and did a little research and I loved that they wanted to come together as a team and donate time to build something special together. I may be mistaken but it seemed like sometime after the 2000 synth release (it may have been a year, maybe two) I seen another AudioKit release, separate from the original AudioKit start to release apps … I may be wrong but I feel like maybe some of the guys that worked on some of (AudioKits) first few releases must have started another “SISTER” team, with some of the developers… But these guys started making some KILLER synths! They have some great ideas, and pushing the envelope hard, milking the IOS platform to push out some creamy, milky smooth, synths, and then just jump into some hard hitting, face smashing, bass thumping, jaw dropping synths! They are fun, they are easy to use, but serious! I would love to see maybe a nod to H.G.Fortune with some of the amazing work he did on the Windows platform, it would be almost a shame not to introduce something like the WOF by HG Fortune! I have paid for every app the day they release it… So I can support these guys, the work they do is legendary, and YEARS to come will still be being used …. I have kept all my old iPads, from my very first iPad 3rd generation… some of the apps that are on that iPad can NEVER be found again, because the developer didn’t keep up with updates… like the Original ALCHEMY app, released on iOS back in 2010… most people haven’t even seen that app… because it became a part of Logic and Garage band… I say all that, just to say…”Hold on to these apps!” Get them, support the devs… because these apps will be legendary one day, and you would have been smart enough to buy them, and hold on to these apps system you downloaded it to…because it will always been on that system.

Fantastic sound! wow!

I have most of this developers other apps. They are good and I enjoy them but this is the first time I’ve felt compelled to write a review and give stars. This thing sounds amazing! Really great. Great tones. Sounds real. . Can’t wait for the prophet five! This is a must buy! Really excited to see what else this developer comes out with. Kudos!

ABSOLUTE BEAST

The fact that this app has the exact same features and sound characteristics as the original $25K synth for not even a fraction of that price is just mind-blowing. The sharp, polished, lush, and laser-like feel does more than define the sound of the 80s, but literally takes you there. One thing I would add would be a UI style customizer, where you can switch between your own style, or the original JP-8’s layout and color scheme.
