Hi all,
I am trying to compile Dario Sanfilippo’s excellent sounding modified chaotic
differential equation synths for supercollider. I am only getting DC offset in
SC. I have made a super stripped down version with hard coded values. This
works fine in the faust online editor (I get oscillations), but in SC I just
get DC offset. Any ideas? Obviously the goal is to use the commented out
process line.
Thanks,
Sam
import("stdfaust.lib");
LotkaVolterra_A(L, mul, a, b, c, g, dt, x_0, y_0) = (mul * (x / l1)) , (mul *
(y / l1))
with {
l1 = max(1, L);
}
letrec {
'x = fi.highpass(1, 10, tanh(L, (x_0 + x + dt * (a * x - b * x * y))));
'y = fi.highpass(1, 10, tanh(L, (y_0 + y + dt * (g * x * y - c * y))));
};
tanh(l, x) = l2 * ma.tanh(x / l2)
with {
l2 = max(1, l);
};
process = LotkaVolterra_A(4, 0.1, 4, 1, 2, 1, 0.1, 1, 1);
//process(limit, mul, a, b, c, g, dt, x1, x2) = LotkaVolterra_A(limit, mul, a,
b, c, g, dt, x1, x2);
