Harmonica ab octave 5 looped note.

A simple multi-sampled synthetic spacebass pack, containing 25 samples, derived from 2 octaves of a home made soft-synth patch. The original quality was 24 bits with a sample rate of 88. 2khz, which i converted with a very good src to 16 bits and 44. 1khz. Not that is was that important after all considering the fact that the patch itself has a grainy character in the higher frequencies. . . No compressing, equalizing whatsoever involved, the panning is pretty wide tho, with left and right sounding rather different, but in stereo it still feels pretty balanced i think.
