This paper reviews some of the recent advances in real-time musical effects processing and synthesis. The main emphasis is on virtual analog modeling specifically digital emulation of vintage delay and reverberation effects tube amplifiers and voltage-controlled filters. Additionally adaptive effects algorithms and sound synthesis and processing languages are discussed. 1. Introduction Real-time musical effects processing and synthesis play a part in nearly all musical sounds encountered in the contemporary environment. Virtually all recorded or electrically amplified music in the last few decades uses effects processing such as artificial reverberation or dynamic compression and synthetic instrument sounds play an increasingly larger part in the total musical spectrum. Furthermore the vast majority of these effects are presently implemented using digital signal processing DSP mainly due to the .
