Great audio quality recordings Niels.
Long time ago I used to play the SD1 and I think there still is a tiny time delay (gap beat-wise) while switching from/to intro's, variations and endings.
The best one (to detect it) is the Bossa.

This 'feature' was already in the Solton X1, the Ketron SD1...... and STILL in Audya!! (unbelievable)
