New developments in the digital organ market are often accompanied by huge devaluation of older digital organs. If you wish to stay on top of new developments you will generally have to trade in your organ for a new one, which often entails substantial financial expenses. This is the reason why VAN DER POEL organs contain sound made by a simulation program and not by hardware. The simulation program can be changed easily. Updating to the latest developments in simulation can be arranged on site. Custom updates, changes or enlargements can be accomplished without replacing the organ.
