#X text 14 10 Scanned synthesis is a sound synthesis method developped
by Max Mathews et al. It is about dynamic wavetables \, where the wavetable
is the result of 'scanning' the state space of some slowly moving (haptic)
dynamic system.;
#X text 15 77 I will use this idea in a more constrained framework
\, namely a (non)linear state-space system with state represented by
a (circular) vector of real or complex numbers.;
#X text 13 137 This is the same framework that covers discrete filters
and linear systems \, and their nonlinear versions \, mostly called
recurrent neural networks. The big advantage of this stucture \, is
that it is very well defined mathematically \, and can host the FFT/IFFT
to bring more intuitive control parameters into the picture.;

#X text 12 183 This object connects the rest of the framework \, which
operate on periodic wavetables \, or their transforms (spectra) \,
captured in dsp buffers \, to normal audio streams.;
#X text 14 96 dynwav~ is an object from creb. It uses an incoming dsp
buffer as a wavetable to be interpolated. This avoids having to deal
with arrays to store the wavetable. dynwav~ additionally interpolates
between the previous and last received wavetable \, to avoid clicks
in the playback.;
#X text 14 35 This technique is equivalent to wavetable synthesis \,
with the exception that the wavetable changes gradually \, at a haptic
rate.;
