I have a voice synthesizer, based on 5 paralel formant filters. I use the reson~ object for the paralel filters.
My problem is the following : quite often, suddenly, while the input signal and input arguments (gain, central frequency and Q) of reson~ remains the same, signal is cut (no signal) at the outlet of one or several reson~ objects.
To find back signal at the outlet, I have to reinitialize the reson~ object by copying and "pasting replacing" it (sending to it the message clear keeps the signal cut).
The strange thing is that when I copy and paste replace one of the not working reson~ objects, then sometimes another or several other reson~ objects which before were ok stops to outlet signals too ...
I can quite easily reproduce the issue just by copying and pasting the subpatch where my 5 reson~ are.
I use Max 5.1 on Mac OSX. Sorry I can't enclose the synth to help you. I don't any error in the Max window.
Until I find a solution, I think I'm going to try to use fffb object instead of reson~ one, even if it's not adviced for parameter changes (Maxhelp file : "but for the sake of speed does not accept signals for parameter changes.")
Thanks for your suggestions.
