Corpus-based concatenative synthesis plays grains from a large corpus of segmented and descriptor-analysed sounds according to proximity to a target position in the descriptor space. This can be seen as a content-based extension to granular synthesis providing direct access to specific sound characteristics. The interactive concatenative sound synthesis system CataRT that realises real-time Corpus-based concatenative synthesis is implemented as a collection of Max/MSP patches using the FTM library. CataRT allows to explore the corpus interactively or via a written target score, to resynthesise an audio file or live input with the source sounds. We will show musical applications of pieces that explore the new concepts made possible by corpus-based concatenative synthesis.
