VoxSyn Pro is VirSyn's voice-controlled synthesizer and vocoder app for iOS devices.
VoxSyn Pro combines voice-driven control with a full synthesizer engine, letting a performer shape presets by singing or speaking rather than programming parameters by hand. Its 22-channel vocoder, a preset pool drawn from the TERA engine, and a random sound generator give it a broader synthesis palette than straightforward talkbox or vocoder utilities.
Integration with AUv3 hosts, Audiobus, Inter-App Audio, and CoreMIDI places it inside established iOS production setups. Within VirSyn's own line it extends the vocal-instrument family started by iVoxel from vocoding toward free synthesis of the voice.
App Store reviewers report difficulty getting the plug-in to appear in some AUv3 hosts, audio clipping on common inputs, and unanswered support requests, and the listing's rating average sits at a modest level from a small number of ratings. The most recent published update on the listing dates to late 2020, leaving a long gap without maintenance releases.
Competing offerings cover adjacent ground: BLEASS Vox gives iOS musicians a voice-driven synthesizer, Vochlea's Dubler 2 addresses voice-to-controller workflows, and VirSyn's own iVoxel and Matrix Vocoder serve dedicated vocoder use. A synthesis-first design asks more of the host environment it runs in than a single-purpose effect.
VoxSyn Pro appeared on Apple's App Store in 2019, during the period when VirSyn was extending its desktop synthesis heritage into iOS instruments under developer Harry Gohs, whose VirSyn line dates to 2001 and the TERA synthesis workstation. The listing carries a 2019 copyright in the developer's name.
The app moved through 2.x releases into late 2020, with updates adding AUv3 stability fixes, Cubasis compatibility corrections, and Bluetooth MIDI in the October 2020 2.1.0 release. It remains available on the App Store for iPhone and iPad within the developer's current catalog.
VoxSyn Pro is an iOS instrument from VirSyn that turns a live vocal input into a synthesizer and vocoder performance. The app tracks the pitch and timbre of the performer's voice and uses it to drive sounds drawn from the developer's TERA synthesis engine, playable alongside a hexagonal harmonic-table keyboard and external MIDI gear.
The offering sits in VirSyn's mobile catalog beside the vocoder-focused iVoxel and the developer's wider range of iOS synthesizers and effects. It ships as a paid download on Apple's App Store, supports the AUv3 plug-in format and Audiobus for use inside host apps, and addresses musicians and producers who want voice-led sound design.
