Can emulate a wide variety of reed organ variations, as well as timbres that resemble instruments from accordians to pipe organsPeti is a unique VSTi, which uses hybrid FM synthesis technology to emulate the sounds of the Harmonium, a member of the Reed Organ family, also known as "pump organ".

The Harmonium in its smaller form is widely used in north Indian music and, as derivation, in pop and rock music too for its full and sweet sound.

Peti is capable of emulating a wide variety of reed organ variations, as well as timbres which resemble instruments from accordians to pipe organs, and even the famous melodicas of reggae dub music.

Peti allows the user control over the emulated Bellows mechanism, with 11 different modes providing 'automatic' or manual pumping and appropriate modulation. It also includes two separate 'reed banks' for the widest possible range of reed organ timbres from its hybrid synthesis system.
