Roboto AUv3 Singing Synth
Singing Voice Synthesizer
Free · Designed for iPad
Write a melody, type a word on each note, and Roboto sings it. A synthesized singing voice with ten presets, automation curves, WAV and MIDI export. AUv3 and standalone.
Roboto is a singing voice synthesizer. Write a melody in the piano roll, type a word on each note, and Roboto sings it. No samples are used: the voice comes from a glottal pulse source, five formant resonators and shaped noise for the consonants.
An animated robot face follows the voice with its LED eyes and mouth, next to a live waveform and the lyrics lit in time.
PIANO ROLL AND LYRICS
• Draw the melody in the piano roll and type a word on each note
• A note named + sings the next syllable of the previous word
• English words are turned into phonemes by built-in rules and a word list
• Phonemes can be typed directly, for example S-T-R-IY-T
• Select notes with a box, then move, duplicate, cut, copy and paste them
• A note named - keeps singing the vowel before it at a new pitch
• 23 built-in songs to try, in every language
TEXT TAB
• The whole song as text, one entry per note in the form word:note:beats
• Type a song from scratch or paste one in
LANGUAGES
• Sings in English, German, French, Spanish, Japanese, Russian, Finnish, Swedish, Italian and Portuguese
• Spelling rules for each language and vowels measured from native speakers
VOICE
• Ten voice presets: Default, Robot, Soprano, Bass, Child, Whisper, Choir, Opera, Giant, Alien
• Transpose and tempo, with optional sync to the host
• Glide: how fast the pitch slides between legato notes
• Vibrato depth and rate, jitter and breath
• Consonant level and length
• Formant shift (vocal tract size) and formant bandwidth
• Reverb and double track
• Sliders show their value on the thumb, and above your finger while you drag
AUTOMATION
• Curves along the song for volume, pitch bend, vibrato depth, breath, formant shift and chorus
• Curve points snap to the grid and are sized for touch
• All voice parameters can be automated by the host
MIDI
• Keys from C1 upwards sing from the matching bar for as long as they are held
• Keys on MIDI channel 2 change the sung pitch live without changing the words, sliding between keys at the Glide speed
• Controllers drive volume, vibrato, breath, formant shift and chorus
• Bluetooth MIDI in the standalone app
EXPORT
• WAV audio
• MIDI file with notes, lyrics, tempo and the curves as controllers
