Download Instrument reusability scheme in PWGLSynth
This paper presents our recent developments that aim to make the instrument definition process of our visual synthesis environment more accessible to a broader audience. There are several novel aspects that aim to overcome some of the classical limitations found in sound synthesis systems. After an introductory section we discuss two advanced examples where scores containing several model-based instrument parts can be realized without having to edit the original instrument definitions. In the first one, we can duplicate instrumental parts of a single instrument definition. In the latter example, we can mix in a single score several instrument models with the help of a mixer patch that is automatically created by system.
Download Compositional Sketches in PWGLSynth
PWGLSynth has already a long history in controlling physicsbased instruments. The control system has been score-based, i.e. the user prepares a score in advance, and by interactive listening process the result can be be refined either by adjusting score information, performance rules and/or the visual instrument definition. This scheme allows detailed control on how the instrument model reacts to control information generated from the score. This paper presents a complementary approach to sound synthesis where the idea is to generate algorithmically typically relatively short musical textures. The user can improvise with various compositional ideas, adjust parameters, and listen to the results in real-time either individually or interleaved. This is achieved by utilizing a special code-box scheme that allows any textual Lisp expression to be interfaced to the visual part of the PWGL system.
