What MONK-1 does
- MONK-1 plays MonkSynth, a formant vocal synthesizer, with twelve singers from Jerry the monk to Peppo the pizza.
- PRESETS turns through the singers, each with its own voice, drawing and stage, its mouth moving with the vowel.
- The keys play one voice at a time: the newest key held sounds, and moving between held keys glides.
- Velocity sets each note's level and aftertouch moves the vowel towards "ee", bends the pitch up, or does both.
- HOME, EDIT, LFO, FX, ENV and GLO each bring up four knobs, and ALGORITHM turns the vowel from any page.
- PLAY holds a note after you let go, and OCT/OCT+ shift the keys two octaves either way.
- MONK-1 saves by itself a few seconds after you stop, and SAVE stores every singer's voice at once.
- Over USB it appears as a MIDI device, sending notes with velocity and polyphonic aftertouch and singing what it receives.
Its modes
- Sing
- Set the vowel, head size, breath and glide for the singer you are playing.
- Choir
- Stack up to ten voices and set their detune, head spread and level.
- Vibrato
- Set vibrato depth and rate, and tune the whole voice up or down.
- Echo
- Set the amount and time of the stereo echo after the voice.
- Envelope
- Shape attack, decay, sustain and release for the singer.
- Touch
- Decide where aftertouch goes and how strongly velocity and pressure respond, shared across all singers.
