The sample sound is ok, but the left hand's register is missing the about a fourth down. It should go down to a C2, the samples go to F2. I needed the sound as a reference for writing arrangements on Finale. I haven't researched why but pitches sound an octave lower than written. I can only write to an F3, and it sounds as an F2.
I'm glad I bought it on sale, not the 90$ that it costs, for an unfinished, octave transposing sample so that it can fit on a MIDI accordion.
