Is the noise osc actually a single sample triggered every time from beginning?
Because weirdly when I use noise, and you can test this with turning any tonal oscillators off, by playing two notes at the same time or with a slight delay results in pretty bad phasing..
In analog synths and even my Hydrasynth playing noise polyphonically should just be louder noise, not these phasing sounds.
A little recording of what I mean:

Also there's something fishy with the oscillators themselves aswell. The quality of them in different pitches are quite off, there's some weird beating going on during some notes.
For exaple in here, first three notes are played on my behringer pro800, the last three on Pro A5.

Yes the filter is more opened on pro800 but thats not the issue, Im getting these weird aliasing beating tones. And the beating tempo is consistent on every note, which again suggests to me that these are samples being pitched up and down so that it causes the aliasing artifacts?
I may be totally wrong tho..
Sorry for nitpicking, but since this is so heavily hyped as an emulation and "true sounding", it kinda fails at pure tones..
What is LFO 1s destination?
Edit: I see it’s controlled by the mod wheel with destinations on FLTR page (why is this on the filter page?)
And third comment from me, since I'm testing it in real time now, but I think people reading this thread should know between all the praise.
The knobs and actually building a sound seems to be quite broken right now. I've had already multiple failures dialing in filter attack (it glitches out and makes quite random envelopes), in multiple presets the OSC B volume is visually up, but is actually silent, fiddling around with it does nothing;
closing the filter "slightly" sometimes jumps fully open, then loses the env amount etc etc.
Yes the presets are full sounding and the prophet vibe is certainly there. (Although too much drowning everything in delay and reverb, but that's my personal gripe with modern presets)
But as a reliable instrument it's not full release level yet..
Im on ipad Air M2 11inch
We ARE a little spoiled, aren’t we? 😉
Honestly I find the layout of this synth to be all over the place. It’s confusing. It’s worse than the J8 to be honest, which is also not laid out well. They don’t really follow the signal flow and things are hidden in unexpected places.
I think the Filter should be on its own page with the pro panel not hidden. Then use the space saved to organise the other sections more logically.
not nitpicking at all. very valid argumentes.. it’s what i wrote earlier..
and try sweep cutoff on fast lfo > filter modulation with max resonanance 🙉 and compare it with your P800..
oof.. yeah thats a bit rough.
Thats kinda the audiokit brand thing, that there's this two row system where everything can be everywhere..
but to be fair I've never actually understood how the hell it works. When pressing OSC multiple times, why should the lower half be flapping around all the other pages?? Now when you press osc twice, press filter and press osc again, it's just jumbled up to whatever configuration.
I want a "home" button that brings me to the main panel, that the developer advertised as "all the main prophet controls fit on one screen"
Good point, it confuses. And why are lo-fi and the chorus on the Arp page and not on the FX page?
This is probably very useful feedback, especially with the audio examples.
Did you start with the init preset as I can’t hear the beating when playing the same notes. I am on the beta version though so might be different to the App Store version.
Or it could just be my ears! 🙉
How come the preset browser window stops me from scrolling & selecting presets higher than #70? Actually it’s the last 5 or so in any bank that can’t be scrolled.
Is that how the original hardware works? (Joke)
This was on iPhone 16 Pro Max iOS 18.7.1
EDIT: it’s fine if I minimize the keyboard, so I guess that isn’t an actual issue, but it would be nice when auditioning with the medium keyboard that the browser menu kept scrolling to the bottom, mostly because Apple’s bar is annoyingly in the way on the small keyboard.
Sounds great so far but noticed a few issues... I don't see a "hold" option for the ARP when using it as an auv3. It's there with the keyboard in standalone...
Also I'm getting stuck notes when using it in standalone mode with a a reface cs controlling it. Works fine in AUM with the reface and works fine in standalone with a launch key 49 so not sure what's up with that.
Is that with the rev 3 and the modern smooth?
I must be listening to a different synth. Everything I’ve done so far sounds like I would expect. Just have to be careful with filter res but otherwise it’s great. 😎✌🏼
I hear this argument way to often and I don't get it one bit. Should we really bother at all if the sound we get is "what you get for this cheap price" If so it might be better to go back to desktop where you then can argue, as it's 100% higher price should be 100% better (it's not so...). I get that you say it with a smile but still, it's a boring thing that comes up way to often when we discuss quality on iOS.
400+ presets for five bucks! whoot, whoot!
You already got feedback on this but I still want to say that it is exactly what we need, tell it like you feel without being rude is what takes stuff forward. Overexcited praise do nothing and can even mislead a developer. Just wanted to fold that in there. Moving on 😁
This sounds like a sample rate mismatch. Notice in @gregsmith's example it is smooth. iPhone/iPads should default to 48k now. I'm guessing your DAW or interface is running at 44.1k.
I hope we both agree that REPRO sounds massively better. That is true analog emulation, a well-crafted filter which does what a real analog filter on the Pro-5 does.
Somebody would say "nitpicking," but this is not nitpicking — this is the very foundation of how modulation and the filter are implemented internally (I don't want to get too technical here; very simplified, it's about how often the cutoff value is updated by the LFO value). From such foundational elemnets then arise overall massive sound and full sound spectrum true emulation.
REPRO sounds rock solid, A5 like a cheap Game Boy. Typical problem with all AK synths (and a lot of other iOS synths, by the way, which are made by basically just gluing together some parts of code downloaded from the internet without any bigger effort to do things properly).
Yes, in "modern" mode it is a TINY bit better — it is not a horrible disaster, but just sub-average. That doesn't mean that "non-modern" mode emulates some older HW — not even remotely; "non-modern" mode just sounds horribly bad. The old Pro-5 doesn't sound like a cheap Game Boy
))
Just a detail — the PROA5 LFO goes only to 16 Hz, where REPRO / Pro-5 goes to 20 Hz (subtle difference, but this is the problem: IF the A5 went to 20 Hz, the problem I am illustrating here would be even more obvious).
Sorry, but when we are talking about a synth which is marketed as an emulation of some HW, I would expect it to sound at least a bit close to that HW. This is not the case.
And BTW — modulating oscillator pitch with a fast LFO is the same problem. When it comes to oscillators — don't even get me started on how on the Pro-5 (or REPRO), when you turn on both saw oscillators, they nicely and slowly phase, where on the A5 it's just a cold, digital, sterile, synced flow (it basically just increases loudness, like turning on the second oscillator on the same wave).
And the famous Pro-5 modulation of OSC A with OSC B turned to "low frequency" mode?? On the A5 it's a joke, it just sounds like an LFO, it doesn't go even remotely close to the original or REPRO, which produces beautiful FM-like modulated sounds (not sure of the exact numbers, but I think REPRO's OSC B in "low" mode goes up to 500 Hz).
This !!
@dendy @Pxlhg Alright, fair point.
Dendy, I respect you and u-he a lot. Repro is a great synth.
I just don’t think it matches a Rev3 in every detail. Especialy the filter. You can see a comparison here in the first 2 min:
Another example is PWM. On the Rev3 I used, the sound does not go silent with the PWM knob all the way down. The U-he does. From a programming standpoint their way is easier to implement, but inaccurate.
I could go on.. you mentioned "Lo-Freq" mode going to 500 Hz, that's not accurate. The Rev3 goes from 0.04 to 30hz as does Pro-A5, and Pro-A5 is sample accurate.. The U-He looks like a Prophet, and is a great sounding synth. But, I'm not sure I'd call it accurate
Pro-A5 is based on filter code from a German engineer who made a $200 desktop synth plugin. I think it is a very strong filter model.
To my ears, it belongs in the same class as Arturia and Softube. For reasons I can't legally mention
I like Matthew's apps. I think they are a great value, and I love how they bring this niche community together. I'm also grateful to have the opportunity to make presets for the community. It really does feel like we are all in it together.
That being said, criticism is okay too. I just know that a lot of work goes into these apps behind the scenes, and it can be demoralizing to have your work dragged on launch day. I don't know. That's just my 2 cents.
Still a plug-in should adapt its rendering sample-rate to match the target sample-rate requested by the host no?
(There's still way, way too many AUv3s out there that don't do proper off-line rendering).
Thanks everyone for all the feedback. Whether we agree on every detail or not, I genuinely appreciate people taking the time to dig into the app and share what they are hearing.
I do love that we are all passionately debating how analog synths should behave, some from people who haven’t actually used the 1980 version. 🤐
This is peak synth forum, and I mean that affectionately as a fellow synth nerd. I genuinely appreciate people caring enough about these sounds to debate the details.
That said, one funny thing about analog synth debates is that a lot of us are comparing memories, YouTube videos, modern reissues, Behringers, VSTs, etc, all of which have different sound profiles.
I’ve said from the start that this app is not going to replace the hardware. Of course it won’t. If you have a real piece of hardware in your studio, please enjoy it.
If you compare apples to apples, this is where the app shines. In comparison to desktop VSTs, I think it holds its own against many $150+ plugins, especially for a $5 iOS instrument. As an indie creator, I’m pretty proud of what it brings to iPhone and iPad.
To my ears, instruments are palettes. This one has a specific sound and vibe that I think brings something special to iOS.
If it inspires you, awesome. If it’s not your thing, that’s totally fair too. No hard feelings. You can always grab a refund and put the $5 toward your vintage synth fund.
I know $5 is still real money, and I genuinely want people to feel good about what they buy. I’m lucky to live somewhere affordable enough that I can keep these apps cheap, and put the proceeds from these apps towards supporting local music education, and still keep improving these apps for all of us.
And honestly, in a couple of years, when the AI slop is everywhere, I think we’ll all long for the days when indie devs were putting their own unique, human takes on synthesis into the world.
Hopefully AI will have crashed and burned by then.
I get your point on the things that are a matter of taste and agree that comparisons can go out of hand quickly.
But my critics were aimed towards things that aren't about agreement, but shouldn't be problems present in a VA pursuing synth at all, basically bugs.
For example the noise phasing thing, could this be somehow a problem in my part or is the noise actually a triggered noise sample?
It's really nice, but for me the filter could be more aggressive. It's just a bit too clean, but it's a great start.
I agree. Haven’t messed with this one, but AK apps all seem to fall short for me. I can’t ever put a finger on why, but I think you articulated it well. No hate on them, they just never get used compared to my other synths. I still get each one for whatever reason - I do think the dev is great and don’t want to see the apps disappear.
