However, few studies have comprehensively investigated the … Until the early 1980s, the tonal palette of commercial synthesizers was limited to that which could be obtained by combining a few simple waveforms such as sine, sawtooth, pulse. The result was shaped with VCFs and VCAs. Wolfgang Palm transcended this limitation by pioneering the concept of wavetable synthesis, where single cycle waveforms of differing harmonic spectra were stored in adjacent memory slots. Dynamic spectral shifts were achieved by scanning through the wavefor…
