FAUST Channel Mismatch, how to tackle it ?

[DabDab]

How can I get rid of FAUST channel mismatch error ?
Input = 1, Output = 1 HISE expects 2 . How can I tackle it ?

import ("stdfaust.lib");
f0 = vslider("Freq", 100,60,1000,0.1);
Q = vslider("Q",1.0,1.0,3.0,0.01);
dtune = hslider("Detune", 100,0,300,0.1);
process = wa.bandpass2(f0, Q, dtune);

try this...

process = wa.bandpass2(f0, Q, dtune) , wa.bandpass2(f0, Q, dtune) ;

@Tania-Ghosh Excellent... Thank you. :)

@Tania-Ghosh Excellent... Thank you. :)

Ok to make sure the concept is obvious, your initial code is sending in a stereo signal, the faust module you are using expects a mono signal. So there are a couple of ways to fix this. you can pass in a mono signal to the faust module in your scriptnode network, or as @Tania-Ghosh demonstrates, there's the more elegant way of make your Faust network expect a stereo signal, by duplicating the faust call in the process node thus:

process = yourFaustProcess(and its params), yourFaustProcess(and its params);

see the comma there? its used here to duplicate the channels, so now there are two channels....stereo and all is right with the world..
