What's New in Pro

1.4.2

July 19, 2026

THANKS EVERYONE! • 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 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. Mono Legato now more strictly cuts off lingering release tails after keys are released, for a more traditional mono synth response. • FIXED: A few presets could play with an unexpectedly fast LFO or "mystery vibrato" after loading or saving. LFO rates now remain consistent with the knob setting. MORE FREE UPDATES and FREE PRESETS COMING SOON!

User reviews

BRILLIANT!

Very glad someone has finally done the Prophet V.
It works extremely well, sounds great, and has some excellent modern additions, like the step sequencer, arpeggiator, and digital effects.
Also (very important), the developer is very responsive. Several updates have already come out, including one I requested.
The Prophet V, one of the most iconic instruments of the late 70s and beyond, is on iOS. Strongly recommended.

An enjoyable synth with excellent support

This synth is a joy to use and is getting better all the time. When I emailed the developer about trouble importing a .scl file, he got back to me right away and it was fixed in the next release. Fantastic!

Epic but Needs Easy Bug Fix

I’m loving the tones I’m getting out of this! However, as a drummer who’s often playing bass with my left hand, I noticed that in mono mode, you still get overlapping polyphony with a long Release. Not sure if this is reflecting the original hardware (for instance, this isn’t an issue in other apps like J6 nor King of FM which I also love), but either way, it’d be great if a future update could include a true monophonic voice mode so triggering a new note while, a previous note is still releasing, will actually retrigger the VCA instead of adding second (or even 3rd) voice.

non profit organisation 🙃

very prophet synth 😃

とても良く出来ています。音色セーブ時にはちょっと注意が必要

Prophet-5のエミュレーションアプリをずっと待っていました。リリースしてくれてありがとう。以前当レビューでノイズの問題を指摘しましたが、V1.3で改善されました。プリセット音色にも面白いものが多いです。

ただ、エディットした音色がUser Bank以外にもセーブ出来てしまうのは少し問題だと思います(プリセットサウンドのアップデートで、以前作った音色が消えてしまいました)。こちらも改善してもらえると嬉しいです。
