Ensemble Effect
While an organ’s windchests will play a major part into how the tone and tuning changes as it is played, the ensemble effect accounts for minute changes in tone and tuning take place when the air supply of the organ is stable. This is another small, but important, detail when it comes to the actual sound of an authentic pipe organ, and with Physis®, we’ve been sure to add it as a feature.
Our algorithm can implement the ensemble effect as it would occur with a fully-built, conventional organ, so you can offer the same sounds and get the same experience you’re used to.
Variable Attack based on real time computation
As you know, when you play the same note twice or repeatedly on a pipe organ, the attack of that note is not the same. This is because when you play a note repeatedly and quickly, there is already air in the pipe, which creates a different sound against the inner walls of that rank than it would if there wasn’t any air at all. Older sampled sound technologies have at sometimes incorporated ‘random’ attack.
Unfortunately, the randomness is just that. The sampled sound organ does not determine how the attack should sound in real time based on what precisely the ORGANIST is playing or doing at that moment in time. It is only randomly selecting which attack sampled to play, which isn’t what happens in a real pipe organ.
Physis® Technology on the other hand does.
