Kolozsvár Pipe Organ Samples (KOL) is a baroque virtual pipe organ chromatically sampled stop-by-stop. The organ was originally built by Johannes Hahn in 1752 and was restored in 1996. Most of the historic pipework have been reserved in their original condition, and another Hahn organ from the same year was also saved and used as the positive. The St. Michael's Church is located in Cluj-Napoca (Kolozsvár in Hungarian), Romania, and it is second largest church in Transylvania. Due to its inner properties the church is still relatively dry compared to its size, providing a well balanced church acoustic. The instrument has 35 stops in three organ cases.

Besides its photo-realistic modelled, extended and full-featured console, the Kolozsvár Pipe Organ Samples supports the Dynamic KeyboardMass™ control to provide a realistic playing experience. Adjustable tracker noise levels and an easily adjustable acoustic perspective in the Professional Edition are also supported.

The virtual Kolozsvár Pipe Organ financially supports the original instrument.
