Jan Wim is busy "drying" Utrecht with all fancy kinds of audio processing and filtering. I tend to sell my rear active boxes to get some money top buy Fatar 64LW keyboards since I always play with my fabulous Focal Classic headphone, instead of spending money on Reaper, and other more expensive acoustic correction software and hadrware.
Here is an improvisation where all stops and couplings are used. The only stops I didn't use were the 2" and 4" Pedal stops. The recording is done straightforward via Hauptwerk and in Audicity converted to 192bps mp3, without equalizing, etc.
