Moppel Tetra

Moppel has released Tetra, a freeware synth created with SynthEdit.

Tetra generates a bandlimited quadrature signal, ie. a stereo signal whose harmonics differ pairwise by 90 degrees. By morphing between two definable timbres, Tetra can create a wide range of unique sounds.


  • Stereo output of bandlimited quadrature signals with up to 1000 harmonics
  • Morphing between two timbres, controlled by an envelope
  • Copy & Paste buttons for quick storing and restoring of all control settings
  • Control changes may affect the sound either immediately or when the next note is played
  • Text field input for all controls
  • Freely selectable polyphony with up to 16 voices. Note sliding. Adjustable pitch bend range
  • Envelope and key tracking controlled volume
  • Freely adjustable Attack, Decay, and Release slopes
  • MIDI control of all parameters (NRPN)
  • 100 presets

Visit Moppel for more information and a link to download Tetra.
