The single keys at the beginning of the keyboard (C2-C3 white notes only) contain a variety of percussion instruments (2 wood blocks, an Irish bongo, a mini rain stick, a mini swinging drum, a tambourine, a mini hollow wood log and a mini wooden scraper). Then the black keys further up are groups of instruments that cut each other off. For instance the first group of black notes (F#3,G#3,A#3) are all samples from the big conga but with different hit types. The next 2 black notes are a dear skin bongo. The next 3 black notes are the little conga. The next 2 black notes are a little metal bongo. The next 3 black notes are the medium conga and the next 2 black notes are a home made plastic shaker. This makes it easy to know the grouped instruments. It is also easy to whack a way at the congas (like real congas) as they are all the black keys in groups of 3 and each conga cuts its own keys off if another is played. I mainly recorded this for the 3 congas and then added the other bits as I had them laying around (some are even from my childrens musical instruments bag, i.e. wood blocks from the early learning centre and a home made plastic shaker). The congas are boomy when played hard but with a lot more delicate hand sound when played softly. It is possible to get a variety of sounds and styles with these conga samples.
