#X text 258 168 the [eig <index> <real> <imag>] message sets the eigenvalue
for the corresponding block. there are n/2 blocks \, with n the dsp
blocksize.;
#X text 259 223 you can use [timefreq <index> <60dB time> <frequency>]
for a more appropriate initialization of the eigenvalues using decay
time in milliseconds and oscillation frequency in Hz.;
#X text 256 18 bdiag~: parallel block diagonal state space model (parallel
2d rotations) see bdiag.c for more info. the state equations for one
block are:;
#X text 300 70 state1 = real * state1 - imag * state2 + input1;
#X text 300 85 state2 = real * state2 + imag * state1 + input2;
#X text 258 121 this module is intended to "filter" spectral data produced
by bfft or other short time spectral transforms like dwt.;
#X text 256 279 [bang] or [random] set the state vector to a random
value. [reset] sets it to 0;
#X text 256 327 this patch uses of bdiag~ \, ibfft~ and dynwav~ to
build a 32 voice harmonic modal synth \, with the state excited with
white noise on bang.;
