    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.

    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

    In my personal opinion, it's not helpful to repeatedly call an app with a regular list price of $29.99 a "$5 app", especially if the discussion has points gravitating towards pricing comparisons... So at this point maybe keep it at $5? :D

    Wow, chill.✋

    A praise of the sound of one app, doesn’t mean in any way all others are horrific sounding. And, I clearly stated ” to my ears”, not anyone else’s. And I also stated ”on iOS”.

    I think @analog_matt has made a marvellous effort with this app and I do find the analog sound of the app one of the best on iOS, if not the best after playing around with it. I think the sound extremely well captures the character of analog, in this case the Prophet 5. Years ago, I had the oppurtunity to play with a Prophet 5, and to my ears, the app nails the sound character. It is just like I remember it, or at least want to remember it😁.

    So, I stand by my comment but YMMV of course and people can actually agree on that we sometimes disagree.

    Happy music making with your own choice of sound making gadget, be it hardware/desktop/iOS/Android/fillintheblank!

    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).

    Yes, and it is or else the notes would all be out of tune. But there is a conversion running 44.1k in the host while the device is actually rendering at 48k. I can't say for certain that is the issue, but I don't hear the aliasing at 48k which is the hardware sample rate for iPhone/iPad. No conversion needed in that case.

    Then there's also the case where the user might be using an external audio-interface that can actually do 44.1k without conversion and in those cases some apps can behave a bit wonky, there's been plenty of examples of that over the years.

    Sorry for nitpicking, but since this is so heavily hyped as an emulation and "true sounding", it kinda fails at pure tones..

    not nitpicking at all. very valid argumentes.. it’s what i wrote earlier..

    and try fast lfo > filter modulation on max resonanance 🙉 and compare it with your P800..

    oof.. yeah thats a bit rough.

    Is that with the rev 3 and the modern smooth?

    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).

    Thanks for the demo.

    Repro-5 sure does sound lovely. I unfortunately don’t have a prophet 5 like you do to be able to hear which one sounds more like the hardware.

    I’ve just listened to a YouTube video of the filter stepping on a Prophet 6 and to me it didn’t sound too dissimilar to the stepping in Pro-A5. I’m not sure I’ll be able to find a full speed LFO, full resonance prophet 5 hardware example on YouTube but will have a look.

    I’m actually well above my pay grade here as I don’t own any hardware synths and didn’t know what the famous osc b low frequency modulation until now. I just try and recreate sounds I hear in music I like, and with Pro-A5 I’ve been able to recreate sounds that I know have been created on Prophets, that I couldn’t get to in Zeeon (my absolute workhorse synth).

    I do think you’re being a little harsh with your words though @dendy and you seem to be inaccurate with a lot of your assumptions as @analog_matt has pointed out.

    Hey guys and gals, whatever you say about the comparisons, i get that. 5€ vs 150€ yada yada.

    But this is not the issue with this app right now!

    The issue is the bugs, the noise, the weird phasing, lfo farting out, envelopes that are messed up etc, which shouldn't even be there in the first place.

    When I buy an app, even if it's for 5€ or 29€ later, I want it to function properly.

    Yeah, I think in iOS 18 iPhone switched to 48k. iPad and Mac can be both (recently), but it changes based on the model and OS. You are right about the out of process thing. That can result in receiving a different rate than the host. Also hosts have a preferred sample rate and the actual sample rate.

    You can see in the AK AUv3 example where they set the sample rate to the host. So it is correct, but there might be something else at play. Just put chorus everything! 😂

    Yeah, but not even Apple is consistent with their sample-rates...
    ...hook up a pair of EarPods (the wired USB-C/Lightning ones or the USB-C/Lightning > 3.5mm dongle) and boom Sample-Rate gets locked to 44.1k :sunglasses:

    And ironically audio for video-recordings using the built-in camera-app is still done at 44.1k even though 48k is more or less standard for video, and IDAM is still locked to 44.1k even when using a device with 'native' 48k sample-rate.

    I'll definitely be keeping an eye on WWDC'26 to see if there are any under-the-hood improvements to the way audio is handled on iOS/iPadOS...

    I must say Beep Street's Dagger has one of the best analog filter emulations on iOS. I think this Pro-A5 is a good start, but the filters, which are crucial for the synth's sound, is not a Sequential equivalent. The Repro / UHE is the best VST IMO. Not to say Audio Kit doesn't make some nice Apps is false; their original Synth One is a classic beast, but unfortunately not AUv3. Also, their prices are generous. Thanks for his great work!

    Oh sorry I thought you meant the pure tone beating sound.

    I’ve just checked though and I don’t think I’m hearing phasing with noise playing middle c and the g below. I wonder if it’s part of the same sample rate problem.

    I don't know the internals of Matthews app, but I do know the AudioKit Framework.

    Noise - Could be a sample or a repeated random seed that restarts with each press. Either way the behavior you would prefer could be addressed by changing the start point on each press or having that noise oscillator free running.
    Phasing - Did you see my note about sample rates? Try 48k. 44.1k could be investigated, but I still suspect it is sample rate conversion related.
    LFO farting - In the free, open source AudioKit framework different effects are Node based running in different DSP processes. With very fast LFOs they can only render so many frames per second. The trade-off is that the LFOs can target almost anything in the app. This could possibly be optimized further, but if you see the same behavior in the other AK Pro apps it probably is-what-it-is.
    Envelopes - I didn't experience that in my testing. I know this is cliche tech advice, but I would start by restarting your device to see if things run more smoothly. Are you using a DAW or standalone? I do know that sometimes if you turn one knob then another quickly it can have values jump.

    Just for reference re the pricing on desktop etc, I ended getting Diva on sale last year for just over sixty notes from Anderton’s , so only twice the full price of this and I really haven’t looked at any other analogue emulations since… (though I am now eyeing up Moog messengers😅)

    Well if you want really great implementaiton of filters (and oscilaltors, and other stuff) on iOS - then answer is very simple. OB-xd. Their implementation is absolutely fantastic. Massive. This is how properly modelled oscilaltor and filtes SHOULD should. No compromises.

    There is a few fantastic sounding synths on iOS, where their authors maybe didn't fueled massive hype loudly speaking about "analog warm soun" but they just ARE that good. OBxD, Zeeon, Dagger, July, RRS Ivoks, Model D (although they are missing oversampling so top resonance on filter generates lot of aliasing) - they are are nice showcase you CAN get top quality also on iOS for just "few bucks".

    I think i terms of filter implementation they both are using same code (initially developed by Vadim Filatov, later bought by DiscoDSP). But here i am just guessing, did not true A/B old vs. new version.

    Also in my opinion OB-X (which is emulated by OB-Xd) was much better sounding synth than Pro-5 byt that's just my personal subjective taste, so take it with grain of salt.

  • dendydendy
    edited June 5

    Fun fact - later OB-X used for filters chip CEM3320 - which is same chip used in Pro-5 rev3 - they didn't sound exactly same, obviously, but were built on same architecture. On other side old PRo-5 rev1,2 were using SSM2040 and had much dirtier sound when compared to CEM3320 in rev3.

    I think you should be able to find both these filters emulated in Serum or Vital under the name "OTA Clean 24dB" and "OTA Dirty 24dB" (or something like that) - clean is rev3, dirty is rev 1,2 ;)

    "Modern" take - rev4 released in 2020, uses CEM3320 plus an SSI2140 (modern recreation of SSM2040 which is not available anymore) and has knob "Vintage" which allows to sweep between CEM3320 and SSO2140 .. (so rev4 is like rev1,2 + rev 3 in one package)

    Also modern (rev4) is not just about filter - they have entire circuitry dedicated to introducing various subtle instabilities into oscillators, VCA and even envelopes to make that proper "vintage" sound.

    On desktop, there is also modelled verison of older SSM2040 - it's this plugin:
