Softrave has released Harmonium Pro, a Windows VSTi that apparently boasts a very warm and realistic sound.
Harmonium Pro VSTi is based on samples of real Harmonium Organ from 19th century recorded with different position of overtones switches. Softrave also added analog drift control to add an analog touch to samples or to create new vibrato effects. Samples are looped so you can play infinite notes on keyboard without need to pump air with your legs like in original mechanical instrument.
Price is €50 / $67.
