In RealBand the midi file plays a correct drum track. In the drum window the Eb3 note sounds like a brush slap but the clap icon is moving.

The Brush Kit is usually the same as the Standard Drum Kit with the following three exceptions:

Note #38 is a Brush Tap instead of a Snare Drum.
Note #39 is a Brush Slap instead of a Hand Clap.
Note #40 is a Brush Swirl instead of a Snare Drum.

Some Yamaha synths use a somewhat different map for the brush sounds. On these synths:

Note #25 is a Brush tap.
Note #27 is a Brush Slap.
Note #26 is a Brush swirl.

Question: why do I hear on my CVP-705 the clap and not the Brush Slap.

I go to sleep now to get fresh energy to solve this issue, I hope with the knowledge en experience of the members on this form.

Thanks,
Jan R.
