Theory and Techniques of Electronic Music

This is more an academic discussion about how to actually create the acoustic waves themselves, more for a synth maker than a synth player. Lots of math, but that doesn't bother me. But beware, it's about how to make the actual sounds with mathematical models than using the sounds.

So it's up to you. This is how you say, you have one midi crossfade and you want to mix two wavetable signals (because they are computationally easier on cpu than additive synthesis)

Here we suppose that some signal 0 · x[n] · 1 is to control the relative strengths of the two waveforms, so that, if x[n] = 0, we get the ¯rst one and if x[n] = 1 we get the second. Supposing the two signals to be cross-faded re y[n] and z[n], we compute the signal (1 ¡ x[n])y[n] + x[n]z[n]; or, equivalently and usually more e±cient to calculate, y[n] + x[n](z[n] ¡ y[n]):

I can follow that (with the proper symbols displayable), but I'd rather a guy show me a silly slider or midi knob...and say listen: slide, slide slide...twist twist.

Don't get me wrong, after you stare at dense mathematics (it was all greek to me at first) and you start to see just the ideas, not the language, mathematics is beautiful. In this case, it obscures rather than distills.

Thx again. I do keep reading it.

Must be "Modern Electronic Music" to avoid confusion with 'Electronic Music' of Pierre Schaeffer, Of course we have occlusion in all laguages, so you can say Electronic Music , but thinking right.

Pierre Schaeffer created and stood for electroacoustic music, to be more specific: music concrete, as he called it.
Electronic music is a specific term for music like early Stockhausen did. No recorded sounds, but solely synthetically created.
