I transported it in a hardcase per bike, and it was a hard work. 😉 But so i learned to love synthesizer sounds. So every app that is more like the original is my beloved app. Juno was a large hardware, so i don’t want the origional. But the programming and sounds i mis. The potis, the arp. It was great. Thank you for a mac app version. ### 5/5 — Legit!! *2026-09-25* Latest update sounds great! My only request is that you please make the LFO delay fader fade in with a slow attack like the hardware. This is one of the best parts of the synth in my opinion. Currently, the delay fader seems to delay the onset of the lfo but the onset is more like a sudden trigger where lfo goes from 0 to the set value instantly after a set amount of time. ### 5/5 — Good for experimenting with music *2026-09-16* Amazing so glad there are free apps glad you have free and paid versions of stuff thank you for helping me experiment with music hope you do well ### 5/5 — Must have *2026-09-14* This is an excellent sounding synth and works perfectly with Logic Pro for iPad. I wish there was a Mac version too because I like to start projects on my iPad and finish them on my Mac Studio. Not a huge deal. I just bounce in place and export a wav file into Logic Pro on my Mac instead of a midi file. I’ll always have the original midi file on my iPad if I need it. Hook a midi controller up to this synth and you will be amazed. It has a lot of features and they’re all easy to access. The presets are great but you’ll really want to mess with things and make your own sounds. The sequencer is great as well. I can’t believe this is free. ### 4/5 — Most of your synths I’ve been on tonight 12th September 2026 *2026-09-12* So far tonight I’ve been on nerd, king of fm, j6 ,j8 , king of digital all in Cubasis 3 in auv3 only. I press on a preset then I press on another preset then it automatically moves to the first preset I picked and sometimes it jumps to a different instrument. One minute it’s a pad then jumps to an arp I just cannot keep it on one preset. These synths are awesome, I also have synth one and pro-A5, viral , king of bass which I haven’t used to see if they have the same problem or am I doing something wrong? If not pls fix ### 5/5 — Incrível *2026-09-05* Ótimo app fantástico!!! ### 5/5 — GOAT *2026-08-28* as u can c its a goat app🙏🏾 friendly for poor me🤩🤩🤩🤩🤩😍😍😍😍😍😍🤤🤤🤤🤤 ### 5/5 — One of the best software synths out there (and the rest are the developer’s other synths!) *2026-08-27* So musically playable I was able to record an entire album on a plane trip, each track using a single patch, the step sequencer and sound modulation controls! AudioKit Pro has developed the best sounding and most playable phone synths on the planet—and they sound like they’re from another one! ### 5/5 — Incredible *2026-08-19* I don’t know why or how you manage to give this away without ads, scraping user data or just straight up making it paid… I think you must be a saint on that front, seriously. As for how good it is? It’s one of the best synths on the store in my opinion. Thank you so much for this. ## Frequently asked questions about AudioKit Synth One J6 + AUv3 ### What is AudioKit Synth One J6?
