This is a work in progress...
This time I've added a bit of intentional "munchkinization" to some of the samples. That is, I intentionally use a sample of a note two or three notes lower than normally chosen, which results in a sharper timbre. The choice is randomized. The effect is kind of like playing closer or farther from the bridge on a string instrument. The effect is applied to the finger piano and harp chords and arpeggios.
