I have a friend who's an early music performer. I brought him over to show him GPO.
He was rather under-whelmed by one element. He and I agree that the GPO harpsichord is missing something crucial--release samples.
When you release each key on a real harpsichord, there is a distinctive clicking sound for each key as the "jack" or the armature that holds the quill that plucks the string, slides back into its starting position.
The GPO harpsichord has no release sample and no "jack" sound. To anybody who's heard a real harpsichord performance, this is an obvious deficiency.
I used to own an Alesis QS-6 synth from ten years ago, and my friend still has his. The Alesis has a harpsicord sound that has just such a release sample. We agreed that the Alesis QS-6 provides a more convincing model of a harpsichord, even though it only devotes a few tens of kilobytes in samples to the instrument, while the GPO has tens of megabytes in its harpsichord.
Can I please suggest that when GPO version 3 comes around that you guys look into adding release samples to the harpsichord?
