I recently discovered virtual pipe organ software, Hauptwerk, from a new coworker who is a serious pipe organ player. He hasn’t built his virtual machine yet, but I am able to assist in planning. It’s obviously a DIY endeavour where the final product is as unique as owner because of the modularity.
What really intrigued me was all of the options to retrofit any and old instruments with MIDI. The Hauptwerk lists a few such manufacturers. I found one, Eobody, that really takes it another level basically creating a great deal of modules that are compatible with all sorts of sensors sensors that can converted to MIDI for practically limitless installation purposes. (Think accelerometer, like in a smart phone, as an instrument.) Now I know how BT had some of those prototypical Roland D-beam knock-offs.
