What Speak37 does

  • Every key speaks the next word of a sentence at that key's pitch, and a chord speaks the word in harmony.
  • Twenty banks of sixteen sentences hold folk songs, Latin chants, jokes, beatbox hits, spelling, numbers and eight languages, picked with PRESETS.
  • PLAY speaks the sentence by itself in time from 40 to 240 BPM while the keys only choose its pitch.
  • The RHYTHM page puts sixteen 808 grooves under the speech, KNOB 4 picking the groove, with TEMPO, DRUMS and SWING.
  • Delay, reverb, spread, tone, metal, breath, two LFOs, glide and an envelope colour the voice.
  • EDIT held switches on MOPE, a gloomy robot that remarks on your playing and every control you touch.
  • SAVE held one second stores a whole sound in one of sixteen memories, and USB MIDI plays the keys, picks sentences and sets the tempo.
