Hotone Audio VOCLAS Vocal Effects Processor

From natural pitch correction and layered harmonies to vocoder textures and experimental vocal effects, the Hotone VOCLAS vocal effects processor gives singers an integrated creative platform for stage and studio. Hotone's neural-network processing supports low-latency pitch correction and up to three simultaneous harmony voices, while nine dedicated vocal effects modules and the Morph engine extend the voice into synth-inspired and instrument-like sounds. An analog mic preamp with up to 62 dB of gain and 48V phantom power, 32-bit/192kHz A/D and D/A conversion and a 90-second stereo looper support live performance and recording. Touchscreen control, USB audio, MIDI connectivity and a dedicated guitar effects chain expand the possibilities for vocalists and singer-songwriters building performances around harmonies, looping and creative sound design.

Neural Pitch Correction and Three Harmony Voices Stay Flexible

VOCLAS uses Hotone's neural-network processing for low-latency automatic pitch correction that can remain subtle or move toward a more pronounced electronic effect. Up to three harmony voices can run alongside the lead vocal, with individual parameter control and four approaches to harmony generation. Manual mode allows singers to shape harmony parts directly, while guitar-controlled harmony follows incoming chords in real time. MIDI-controlled harmony uses performance data from a compatible keyboard or controller, and AI mode generates additional vocal parts based on the sung melody. These options allow performers to move between straightforward vocal enhancement and more elaborate arrangements without changing processors.

Morph Turns the Voice Into a Sound-Design Source

The Morph module moves beyond conventional vocal processing into more experimental territory. Vocoder processing blends the voice with a synthesizer signal, while Vocal Synth Modeling reshapes it into synth-inspired tones. Throat-Singing Simulation creates layered overtone-style textures, and Instrument Synthesis transforms hummed melodies into instrument-like sounds. A real-time MIDI Vocal Engine also lets performers use a connected keyboard to control vocal pitch while retaining the character of their voice. Additional modulation, saturation, auto-filter and stutter effects expand the creative possibilities, turning the voice into a flexible source for melodies, textures and electronic sound design.

Analog Mic Preamp and Vocal Cleanup Build the Foundation

Before the creative effects enter the picture, VOCLAS starts with an analog microphone preamp offering up to 62 dB of gain and 48V phantom power for compatible microphones. A de-esser dynamically reduces harsh sibilance, anti-feedback processing helps control unwanted feedback during live performances and a natural gate reduces the microphone signal when the singer is not performing. These front-end tools help manage vocal input before it reaches the processor's creative effects. The system combines 32-bit DSP processing with 32-bit/192kHz A/D and D/A conversion, providing the digital processing foundation for its vocal and instrument effects.

Nine Vocal Modules and a Guitar Chain Cover the Full Set

Nine dedicated vocal effects modules organize EQ, compression, Morph, harmony, doubling, FX, delay, reverb and boost processing into one chain, covering vocal shaping, width, movement and ambience without requiring a separate rack or pedalboard. The FX module provides additional modulation and filtering options, while delay and reverb algorithms allow performers to add space and depth to their sound. A dedicated guitar effects chain includes clean amp, overdrive amp and acoustic simulations for musicians who sing and play simultaneously. The 90-second stereo looper supports layered vocal and instrumental arrangements, giving solo performers another way to build songs and transitions from the same device.

Touchscreen Control and Flexible I/O Keep the Workflow Moving

A color touchscreen, footswitch displays and onboard controls make VOCLAS accessible from the floor or tabletop, while the companion mobile app provides additional editing options. Connectivity includes an XLR microphone input, 1/4" instrument input and separate thru output, stereo auxiliary input, dual balanced XLR outputs, stereo headphone output, USB-C, expression/control input and 5-pin MIDI in and out/thru. USB audio and OTG support allow recording with compatible computers and mobile devices, while Bluetooth audio playback provides another source option. One hundred factory presets and flexible output routing help adapt the processor to different live and recording setups. For performers seeking pitch correction, harmony generation, vocal sound design, looping and instrument processing in one unit, the Hotone VOCLAS vocal effects processor combines those capabilities in a compact performance system.
