The FantomXR I loaded with SRX expansions, however, the display went bad and I am just 1 of many. Anyway, glad to see your SRX software. I need to have the same on this software. It could replace an instrument sometime soon I hope. I agree with the other reviewers basically word for word. ### 1/5 — No MC-707 support *2026-07-07, version 1.9.2* As an early adopter of the MC-707, none of the Roland software has supported that machine, even though it uses the Zenology engine. The TR-8s (and 6s) got software control panels and MC-707 got abandoned. ### 4/5 — Really can be something special *2026-06-28, version 1.9.2* 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 . ### 2/5 — Not creating an account to try *2026-06-27, version 1.9.2* Nope - don’t expect me to set up an account just to try your software. Not at all interested ### 1/5 — Sign up snag *2026-06-24, version 1.9.2* I deleted the app when I could not get past the sign up screen. ### 3/5 — Poor integration with iOS, doesn’t save SDZ files *2026-06-19, version 1.9.2* As a soft synth Zenology is a fantastic synthesiser, capable of VA, FM and S+S sounds from a plethora of classic Roland gear. I have a hardware version and I’d put it in the top five synths I’ve ever owned - if you have one of these and something with character, you’re good to gig. As an app, its still under development, but updates have occurred, with more promised. The problems I have had with it relate to integrating with iOS passwords - on the roadmap for a fix next version - and pasting a long secure password from my Mac. Additionally it does not yet support import of the EXZ sample packs I have in my Roland Cloud account. Full file compatibility - including EXZ sample packs - has also been promised in future versions. One remaining question is the pricing/subscription model on this platform. Given that software becomes obsolete much more rapidly than hardware, Zenology Pro is too expensive to purchase in my use case - solely as a means to program my GM-800. I hope on iPad this will not be the case. ### 3/5 — Filter step noise *2026-06-16, version 1.9.2* Great sounding synth with one problem, step noise in the filter when modulating it with aftertouch from a windcontroller. ### 5/5 — Quiet audio problem fixed *2026-06-16, version 1.9.2* I’m still VERY curious about what this will cost when the introductory period is over, but I’m enjoying the free access to all these great sounds for now! :) ## Frequently asked questions about ZENOLOGY GX ### Does ZENOLOGY GX have ads?
