AudioRealism Bass Line 2 (ABL2) is a simple analog modeling technique. Create a DSP-algorithm that accurately emulates every aspect of the original 303, from growling basses to hollow middles and beeping highs with metal rattling accents. Patterns are composed in a fashion similar to the original using the integrated step sequencer with easy to use manipulation functions such as transpose and randomization. The pattern analyzer is a tool for editing and analyzing patterns. In further aid to help users transition their original patterns into ABL an audio detection algorithm has been devised. The configuration screen allows you to customize your ABL2 to your liking, we even go as far as allowing you to tweak some of the internals such the Filter VCC feed voltage, pre-gain, and basic frequency offset.
