So uninstalled… In response to dev reply…. Yes you’re right, my rating was a bit harsh, so I’ve upped it to 4 stars. ### 3/5 — Can’t use in AUM *2026-05-16, version 1.0.22* I have SynthMaster 1, 2 and SynthMaster 3 player.. they all sound great and are fabulous synths, but only SynthMaster 1 works in AUM, why is that. AUM is one of my primary work environments and is really frustrating to not be able to use the newer versions a particular synth in an environment that worked on the first version. Did you piss off the AUM folks and they won’t let you in anymore? ### 2/5 — Auswahl der Modulationsquellen funktioniert nicht richtig *2025-11-12, version 1.0.22* Eigentlich ein toller Synth aber die Auswahl der Modulationsquellen oder auch Ziele in der Modmatrix funktioniert bei mir (11Zoll iPad Pro 3.Generation) nicht richtig: Es wird ein anderer Parameter ausgewählt als angewählt wurde. Die macht eigene Soundprogrammierung leider fast unmöglich, der Fehler besteht seit einigen Jahren… da ist dann geschenkt fast zu teuer.. ### 4/5 — Broken Preset System for a powerful synth *2025-05-29, version 1.0.22* Firstly this a super powerful and awesome synth. The way presets are saved along with info is broken. You can try save a preset after adding your Author and Bank name into the Info panel but the information upon double checking is gone. Even deleting presets from the save panel does not work. Half time info is saved and the other half of the time this essential process is corrupt. I know what I’m doing, but the app is very buggy in this regard. A shame really since this lets down a solid and essential synth . I hear the plan is to eventually release SM3 on iOS and the presets from SM2 should be able to load into SM3. But sadly the presets system in SM2 has not been fixed and still corrupt after several years. The last update 5 months ago did nothing to fix the issues. Please fix asap Bulent. I know you are busy ironing out any issues with SM3 on desktop, but SM2 really needs a stable preset saving/deleting/info naming fix. ### 5/5 — Great *2025-04-13, version 1.0.22* Great synth…..very nice sounds…..thank you. ### 4/5 — Best synth ever just one thing need to be added *2025-03-12, version 1.0.22* I don’t know if I’m doing something wrong but I’m trying to Pitch bend my samples that i imported from my files and they wont glide. The lead,808,synths will not glide. Please tell me and help me if I’m doing something wrong. If not please make it possible to pitch bend/glide the samples. Thank you ### 3/5 — Please fix the OSC behavior on Square and Saw *2025-02-18, version 1.0.22* on the basic set of oscilators the tone is different when switching from square to saw to pulse, when going back to saw the waveform and tone is different for saw, please fix it :( this is almost a perfect synth for ipad and desktop workflow except for this issue ### 2/5 — Preset issues *2025-01-17, version 1.0.22* Experiencing stuck "presets" with Synthmaster. I'll be scrolling through ones made, or the full bundle, and the screen will flash off momentarily and it will go back to the first preset I started browsing with. This is in Loopy, Drambo, AUM Etc. Dropped quite a bit for the bundle and because of the issue quit using the app ### 5/5 — Synthmaster 2 still one of the best on iOS *2024-12-20, version 1.0.22* Thank you KVR331 team, the preset selection is now back to its normal fast response. 16th Dec. The latest iOS18 update has rendered this app unusable if you want to use MIDI Program Change or just manual selection…..be prepared to wait up to 1 minute for the change to happen! No response from the KVR331 support even after numerous bug reports and forum requests to fix this issue. ### 2/5 — Preset management is a buggy nightmare *2024-11-18, version 1.0.21* The synth parts of this app are great and lots of fun. Would give that 5 stars, but when you start trying to save and manage your own presets the nightmare begins. The browser is horribly confusing and buggy when it comes to user presets. So many weird glitchy behaviors. There seems to be a fundamental very basic bug with how banks are associated with patches. The patches sort by name but don’t always reflect that. The lists have weird selection bugs where sometime multiple things show as selected and you can’t unselect. Hard to figure out how to delete an old version of a preset. When you do finally discover the delete option it seems like it can only delete entire banks? Also deleting a preset seems to delete all copies of it? Moving presets between banks is way harder than it should be. The UI lets you select and drag presets around. Great! But dropping them into different preset banks does nothing. Very frustrating to have hours of work on a preset ruined by weird deletion, sorting, and bank management behavior. ### 2/5 — Great sounding IOS synth, but… *2024-11-17, version 1.0.21* It’s a great sounding synth, but it’s totally broken when it comes to round-trip functionality in Logic between iOS and Mac. So uninstalled… ### 5/5 — Tout simplement l’un des tout meilleurs si ce n’est le meilleur synthétiseur sur l’app store *2024-11-07, version 1.0.21* Fantastique synthétiseur qui nous rapproche au plus près des meilleurs synthétiseurs hardware… malheureusement beaucoup de musiciens n’ont pas compris cela encore . SynthMaster 2 est un must have tant les sons sont super et les possibilités de création sonore sont infinies … sans parler du prix dérisoire même avec l’achat de toutes les banques de son supplémentaires ça reste largement peu cher … voilà vous savez ce qu’il vous reste à faire ### 5/5 — Love it! *2024-10-03* Synthmaster 2 for ipad is so expansive, I haven’t even had a chance to check it all out yet. Everything I have done, so far, has sounded great and was exactly what I was looking for from Synthmaster. I’m going to be tweaking knobs and sounds for awhile with this app. Synthmaster 2 is great! - Grey F♾️l ### 4/5 — SynthMaster 2 not recording inside of DAW *2024-09-22, version 1.0.21* Hi there I am having issues when using SynthMaster 2 inside of DAW(BeatMaker 3) I want to record a sample I made with SynthMaster in to the daw and there is a big delay before it starts to record I have checked this with other AUv3 3 plugins and all works in others when recording in side the DAW can some one help with this plz thank u ### 5/5 — Probably the best synth on iOS … and I have just about every synth on the AppStore! *2024-07-27, version 1.0.21* Probably the best synth on iOS … and I have just about every synth on the AppStore! Every Korg, Moog, AudioKit, apesoft, Yonac, VirSyn, as well as the 100’s of others. I will say SynthMaster 2 sounds as good as the big boys on my Mac Silicon and Windows 11 !!! I just seen that SynthMaster 3 is in beta (God I wish I could have been a tester and make killer patches) oh well! Buy this Synth if you haven’t already, I promise it’s the best sounding synth on iPad and the control is like NO OTHER on iOS ### 4/5 — Great sounding IOS synth, but… *2024-06-29* This is my favourite IOS synth for sound and deep programming. There a cloud sync feature to sync presets between VST and IOS…. And then they blow it all by breaking Logic Pro round-trip functionality. When you open a Logic Project it can’t find SynthMaster 2. Every other app at least opens in Logic but not this one. It ends up being such a pain I just don’t use it any more, which is a real shame. If everyone else can do this KV331, so can you…. Come on! ### 5/5 — très bon synthétiseur mais *2024-05-06, version 1.0.21* l'intégration dans le mode audio de l'app AUM serait géniale , merci ### 5/5 — Great! *2024-05-02, version 1.0.21* A "Master of the universe" of synthesizers… ## Most critical reviews (10 lowest-rated) ### 1/5 — Echt schlecht *2025-06-10, version 1.0.22* Der Synth macht gute Sounds, aber die Modulations-Zuweisung ist echt großer Müll und fummelig. Einfach nicht bis zum Ende gut durchdacht. Ich bin es einfach leid mit diesen iOS Apps. Wer meint, dieser Synth wäre gut, der hat sich auch nur durch die Presets blenden lassen. ### 1/5 — Fürchterliche Sucherei *2023-06-03, version 1.0.17* Anti-intuitiv programmierte App. Ewiges Suchen, keine Erklärungen, zumindest finde ich keine. ### 1/5 — One ist gut hab ich schon lange, der 2 hat langweilige gleiche Klänge, Fehlkauf..2023 *2023-01-01, version 1.0.16* Fehlkauf alle Klänge gleich langweilig, geldgierige Macher.. Im Browser sind oft mehrere Klänge angewählt absoluter Murks.. gehen auch nicht weg, man muss hin und her fummeln.. ### 1/5 — Crashes when opening every time now *2022-11-23, version 1.0.16* Title says it all Yes I reinstalled it ### 1/5 — No Longer Works with AUM…but ApeMatrix works… *2022-07-11, version 1.0.12* SM player, SM1 and SM2 No Longer are Recognized by Updated AUM…. Strangely, ApeMatrix….which I ,up until now, never use….recognizes ALL 3…. I use AUM….so ALL SynthMasters are….OUT ! ### 1/5 — Preset bug still isn’t fixed *2022-07-09, version 1.0.12* iPad 2019 Once SynthMaster is loaded into an audiounit, IAP presets do not load correctly. ### 1/5 — Not yet reliable. *2021-08-30, version 1.0.3* Great synth, but when I move the mod wheel on any of my controller keyboards it causes a lot of the parameters that are assigned to the wheel not to return to their starting position. If there is a solution, please say so if not please update so I can give better rating. thanks! ### 1/5 — Very laggy performance on iPad Pro M1 lets it down. *2021-08-21, version 1.0.2* Amazing sounding app, but it’s current state makes it hard to recommend. I’m aware of the crackle issue and can put up with that (for now), but it keeps playing after I’ve released my midi controller until I select a different preset. Midi input options randomly disappeared for no apparent reason. When it works better I’ll be back and will gladly pick up the IAPs. ### 1/5 — developer don’t accept negative criticism *2021-08-12, version 1.0.2* no more words to say… ### 1/5 — Unusable on my iPad. Devs pass the buck *2021-07-03, version 1.0.1* I have 12.9” M1 2021 iPad Pro and there are sound glitches that are not present on older iPads. Also the unison and voice controls do not respond to touch at all. Reached out to devs and they showed no interest in fixing the problem and blamed Apple. Some people report iPadOS 15 beta fixes the problem. I tried beta iPadOS 15 and it did not solve the audio glitch problem or the inability to use the voice and unison controls. Meanwhile I’m stuck here with an app I paid for (and bought an IAP for) that I can’t use. I won’t be giving this company money again. ## Most praised reviews (10 highest-rated) ### 5/5 — Sean *2026-07-27, version 1.1.2* Truly the go to synth on iOS gives you access to a comprehensive set of features nothing else will. Complicated arps, loading your own samples, rich filters, massive amounts of modulation, rich analogue presets, huge selection presets. I’m not the most techy person so can be a little confused but this synth is a world not a toy. Looking forward to 3 arriving….. ### 5/5 — Nice *2026-06-30, version 1.1.2* Very cool, lush sounds and lots of variations and ways to manipulate sounds to one’s liking , thank you for this ### 5/5 — Powerful Powerful Synth *2026-06-08, version 1.1.2* Update: Developer fixed some issues with preset system. I’m happily enjoying this versatile synth again. It is in my all time top ten synths on iOS. I love it! ### 5/5 — Best synth on iPad *2025-12-24, version 1.0.22* Simply the best synth I own on iOS, I own a bunch korg, Zenbeats and a whole lot of iOS synths but this one brings the closest desktop sound to my ear and I am all smiles, thank you! Btw grab the desktop presets too, you won’t regret, this is a keeper! :) ### 5/5 — Toller Synth mit komplexen Möglichkeiten und super Sound(s) *2025-12-20, version 1.0.22* Viele abwechslungsreiche und gute Presets als Ausgangspunkt. Wenn man möchte, kann man sehr in die Tiefen des Sounddesigns einsteigen mit diesem Synth. Sehr gut die Möglichkeit, dass man nach Registrierung sogar seine bereits für die Mac/PC-Version gekauften Soundsets auch für die iOS-Version herunterladen und nutzen kann ohne weitere Kosten - ganz komfortabel vom Browser aus. Eigene Sounds lassen sich ebenfalls synchronisieren. Das erleichtert es doch enorm, zwischen mobil und Desktop zu arbeiten. Freue mich, dieses nette Plugin auch mobil dabei haben zu können! ### 5/5 — Perfeito *2025-12-14, version 1.0.22* Sintetizador incrível ### 5/5 — More synth than you’ll ever need *2025-11-23, version 1.0.22* Hands down the most comprehensive synth app around. They cover any and every genre. You can either shop through the expansions to match your tastes, or just buy the affordable bundles and browse through those great presets to your hearts content. ### 5/5 — Delicious sound *2025-11-17, version 1.0.22* This is the great one, I use it very often. ### 5/5 — AMAZING *2025-05-18, version 1.0.22* Amazing app - love working with this synth and all KV331 apps - 😌 ### 5/5 — Tremendously powerful synth *2025-04-28, version 1.0.22* This thing is capable of amazing sounds, a great wave table synth on iOS. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
