In each Tb303 collection there are 40 RBS Rebirth Song files. Every RBS Song file contains 16 basslines or sequences, 8 saved in bank A and 8 in bank B, within the second Tb303 section of Rebirth.Each file has its own individual sound and effect settings.Banks C and D are empty and can be used for storing any edits that you make. The Tr909 section includes 16 drum patterns taken from the Tr909 Dance Collection for auditioning purposes. You can use the files to produce basslines/sequences quickly and easily whilst adding your own drum tracks or use them together with our Tr808 and Tr909 Dance Collections.This is the Demo version only, not the complete collection.
