Very low output
May 30
PlayDoh003
I have to agree with the other claims about low output. Even if I route the iPad’s output to an amplified Bluetooth speaker, it’s very low. Interface-wise, it’s pretty consistent with what I’ve seen in Galaxias so far, so I look forward to seeing what this new engine can do - I just need to be able to hear it at a level to where I can properly judge. UPDATE: I must have gotten an update while writing this review because the audio is much better now. Bumping this up to a 4 star review from 3. :)EDIT: I’ve also experienced some of the pop’s reported by others when activating other partials and playing notes in quick succession. Admittedly, I have a 6th gen iPad with A10 processor, so this may be the culprit, but hopefully, Roland can find ways to optimize this for slightly older iPads. UPDATE: I can easily reproduce this when I touch keys near the screen edge, so maybe it’s more of a hit detection issue near the bottom edge of the screen keys?

New Release v1.9.3 only works on newer iPads
Oct 3
trvldr
Overall beautiful work but not yet finished for the general end user. Overall it is very, very promising, but still needs work to scale out to potential users. I just started using the new release on my iPad Pro 6th gen within Camelot Pro and it’s working except that I would like the app to provide 10-15db more of master gain output. My other apps drown out Zenology GX and I won’t go changing levels on hundreds of songs set up for live performances to bring this app into my workflow until gain is addressed. On another note, ZENOLOGY GX v1.9.3 crashes instantly on my older iPad Pro 2nd Gen (A10X / iPadOS 17.7.1). I think it’s failing to initialize and blocking the AUv3 shared directories entirely which is probably preventing the standalone app from unpacking and installing the essential files to get it running. v1.9.2 was working fine on my older iPad. I would hope the developers patch for initialization failures on older tech soon because I’m not the only one out there with an older iPad. All in all, this app can be a home run!

Really can be something special

Roland i really think you got something special here. The big thing please make it AUV3 support . iPadOS is growing into its own OS Platform i believe you guys have a major head start with this one. Other synths like Spectrasoincs Omnisphere, Yamaha synths, haven’t took full advantage of the iPad and iPad Pro processors by the time they developed Apps for them think this synth app will be hard to beat. I will surly buy it when it becomes available at its purchase price. Please just don’t stop at the ZENOLOGY GX Synthesizer make more AUV3 compatible synthesizers. This is why i said at the title this can really be something special .

Roland has work to do
May 20

Unfortunately, Zenology GX for iPad is not really ready for prime time yet. As of 19 May 2026, the app has numerous bugs, including: menus being unresponsive to clicks when using a mouse; .svz export function creates 0kb files;non-compatible with Logic Pro or other DAWs;tiny UI which practically requires an Apple Pencil;inability to see or directly enter parameter values as numbers; difficult to use on screen controls; complete lack of documentation; Perhaps the worst sin of all, though, is that it appears to have been created using a cross platform development tool in Visual Studio or the like, on a PC, rather than in Xcode on a Mac. The app deviates completely from the user interface standards that Apple has set out, and does not use any of the standard controls or UI elements. While it does mostly work, it's the most un-iOS app I've ever used on an iPad, aside from ZenBeats. The UI is an improvement over ZenBeats, but it still carries Roland's signature disregard for the human element. Roland makes good sounds, and good hardware, but even on the hardware, they have failed to grasp the importance of visual elements and of a clean, beautiful user interface. I hope that as Roland goes through this preview phase they will remedy not just the clear bugs but also some of the usability problems. As for right now though, Zenology GX for iPad is not really ready to be a serious tool for music creation.For reference, I own several recent Roland and Boss hardware synthesizers and other devices.
