Moppel - Tetra v1.0 (Pc/Free)

Making Music
Tetra is a free VSTi synth for Windows.

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.
Tetra was made using Synthedit. The sound engine isn't based on native Synthedit modules, though, but newly coded in C++.

* 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.
