REQ: Nusofting Peti SA Harmonium and Accordion
Within the new Peti SA the synthesis engine has been improved (from the previous Peti 2.1) allowing more variations and better emulation of many harmonium and accordion types.
Peti SA also emulates various features of the Harmonium/Accordion, including the noise of air in the bellows and chambers, a "musette" tremolo feature, and "key coupling" allowing a single note to trigger two voices. Keyboard noises are also emulated.
Peti SA provides features to control many parameters while playing: a MIDI CC value of choice, Aftertouch and Velocity. That allows for instance a ModWheel or an expression/volume pedal to be used to enhance the natural performance of the emulations.
