Hi jost -
How about the code I just posted to sc-users? Here it is again,
tweaked for SwingOSC compat:
Server.default = s = GUI.stethoscope.defaultServer.boot;
{|in| MoogFF.ar(in, freq: MouseX.kr(10, 10000, 1),
gain:MouseY.kr(4,0))}.scopeResponse
LPF.scopeResponse
HPF.scopeResponse
MoogFF.scopeResponse
BBandPass.scopeResponse
BLowShelf.scopeResponse // by default BLowShelf doesn't mangle much
Resonz.scopeResponse
BRF.scopeResponse
Integrator.scopeResponse
Median.scopeResponse // nonlinear, and therefore interesting
