Dear all
After meeting with its author, I was promised a miracle: that the old Max/MSP book, which was good enough to learn basic of DSP and computer-assisted (algorithmic) music making, within a practical environment, now existed for SuperCollider.
I’m reading it, and despite my (low-mid-level) user, I have to agree it is very good, for the text-inclined programmer (i.e. not if you prefer Max/Pd graphical interface). In other words, it makes SC approachable for what it is in much more curated and careful ways. I don’t know if @spluta would agree, but hey, he is better than me
