Welsh's Synthesizer Cookbook is a great resource. The author "reverse
engineered" common instrumental sounds to make recipes for dual oscillator
synths with waveforms, noise, modulation, filters and ADSR envelopes for
both the amplitude and the filter. The CDROM with the book includes a VSTi
synth to recreate the recipes. Volume 2 has harmonic spectrum of the
instruments similar to the diagrams in Fig 2 of the paper you reference.
The CCRMA site https://ccrma.stanford.edu/software/snd/snd/sndscm.html is
an awesome reference, anders, thanks for sharing,
