Bass sounds are largely represented by synth sounds and a fair acoustic bass. By far the best, and fortunately most plentiful, type of sound on Planet Earth are percussion sounds and drum kits. The percussion patches are simply outstanding, offering multiple hits on a single instrument mapped across a range of notes. This means the tone of the instrument is consistent throughout the given range, even though the striking technique might be different from note to note. The sounds of the drum and percussion hits are almost without exception perfectly idiomatic and convincing.
Many patches offer velocity switching that makes the sounds even more musical.
You'll find percussion from India, Africa, South American, Europe, the Middle East, and East Asia, and not just drums but bones, bells, tubes, clay drums, boo-bams, slit drums, and rattles. The 26 drum kits are varied and are targeted at specific genres, which makes it easy to switch continents by switching patches. The percussion sounds alone are worth the price of the module. But wait, Bongo, there's more. Each track can be of a different percussion instrument, or adjacent tracks can have variations played on the same instrument.
