Short demo video of the T. Chordstrum built in audio output:
Audio capabilities of the Teensy 3.2 version (may change in later versions):
- Strummed sound, Omnichord like sinewave sound or Autoharp like plucked string sound (Karplus-Strong algorithm). Adjustable volume. Press and hold a chord key, strum with a finger over the touch pads of the strumming area to play.
- Backing chord sound. Default off. Plays when a chord button is pressed and held. This is also played when rhythm is activated, but in a gated pattern, with a separate control for switching on and off. It is on by default. Volume for the backing chord can also be adjusted.
- Rhythm. The Chordstrum uses samples from the Keio (Korg) Minipops 7 for a nice retro vibe. You can adjust tempo and volume, and choose between 16 different rhythm patterns (bass and gated backing chord patterns follow this selection).
- Bass sound. This follows the rhythm pattern, can be switched off/on and adjusted in volume.
