Soundshaper 6.4 has been released. This version revises the options for saving and loading user patches (i.e. process chains), with the aim of making these more versatile. A document explaining the various options is included and a revised user manual will be prepared soon. Users updating from 6.2 or 6.3 have only a few files to replace and would be best to download from www.soundshaper.net/dloads.html .
