VoxSyn Pro turns your voice into the most flexible vocal sound generator ever. Instantly following even subtle modulations of pitch and spectral changes of your voice VoxSyn Pro creates signature vocal sounds far beyond traditional vocoding. Talk or sing into the microphone and you’ll trigger various synthesizer sounds following your voice pitch or the notes touched on the hexagonal keyboard / external MIDI Keyboard. The basic sounds are selected from a vast pool of predefined sounds from the famous TERA synthesis engine which can be further expanded by its unique random sound generator. The harmonic table note layout visualises your voices pitch in realtime and also let you play notes for more traditional vocoder effects. VoxSyn Pro is AUv3 compatible and can be used in AU Host apps like Garageband, Cubasis, AUM and many more. Important: Users of VoxSyn should wait for the App bundle to save money.

Amending my review to 3 stars as I found that the AUv3 version only appears in the effects channel slots for AUM. I expected this to function in the instrument, slot, but it only functions as an effect for source channels like a microphone. Stand alone still doesn’t work for me, I really only get a lot of static over a seemingly dry signal. Mostly I’m annoyed that when I reached out to the developer I heard nothing back. Wish the support was better as there aren’t many online guides out there for this app. ### 1/5 — One Star Until It’s Fixed *2025-02-23* Doesn’t work with inter app audio or as an auv3 currently so can’t leave an honest review until this is fixed. ### 1/5 — Doesn’t work (iOS 18) *2024-11-22* AU crashes, AB won’t connect to session, Standalone doesn’t work at all, M1 Mac version doesn’t even launch… Utterly, totally, completely useless. ### 1/5 — Absolutely usless *2024-08-13* There are much better apps that work. If you need a real vocoder, don’t buy this one. ### 1/5 — Doesn't work for loopy pro *2024-02-20* I bought this to use in loopy pro. Put it on as an effect for a channel and when I put it on the channel it mutes all channels and no audio comes through. Put it on a pre recorded channel and it shows audio but again mutes all audio. If you could assist me I would change my review. Seems like a cool concept if it worked. ### 3/5 — Requires revision *2023-09-18, version 2.1.0* Requires revision and updating! Standalone mode does not work (ios 16.6.1). In the AUM application, the program seems to work, but it does not fit in the iPhone screen in full-screen mode. Перевод:) требуется доработка и обновление! standalone mode не работает (ios 16.6.1) В приложении AUM программа вроде как работает, но не помещается в экране айфона в полноэкранном режиме. Короче - брать можно но бакса за 3, или скрепя сердцем за 5 максимум, не более! ### 1/5 — Auv3 and inter app audio not work??? *2023-07-29* Hello I would like help with my purchase of VoxSyn pro I have a brand new iPad and I have to use head phones with a mic for the vocoder to work.The app is not working as inter app audio or as a auv3 also making the app unusable I would like some help to fix this ### 1/5 — Does not work - unacceptable audio quality *2022-06-17, version 2.1.0* The voice audio quality is terrible, it’s all distorted and cannot be fixed within the app settings. The app should be removed from the App Store or updated asap to make it work as expected ### 5/5 — Another Virsyn Winner *2020-10-29* This company keeps cranking out super duper apps with great interfaces that are as consistent as possible. So many apps by other developers are impossibly complicated for no benefit. Virsyn makes deep apps that are relatively easy to use and similar features have similar interfaces across apps. Isn't the idea to make music smoothly without being constantly confused? Virsyn apps are the best. Hey, if you have a problem with an app, send an email to the developer instead of giving an undeserved bad review. I see reviews that say the app is fantastic but give 2 stars because of the color of the knobs or a small bug that happens rarely. Reviews are to tell others about how good the app is, not to communicate with the developer. Use email to communicate. You can't get a proper answer in a review. Come on, think. ### 1/5 — Only good if you don’t mind static *2020-09-09* After adjusting every setting I can think of, swapping out a few different microphones, and scouring the web for support, I’ve come to the conclusion that this app just doesn’t work. The output of this vocoder is so distorted that it’s unusable. I can’t find any way to get a good, clear vocoder sound. The audio clipping is terrible, every input sounds as if the mic is in your mouth and the gain is all the way up. Maybe you’ll have better luck, but this was pretty disappointing for me. ## Frequently asked questions about VoxSyn Pro ### What is VoxSyn Pro?
