Default VST3 Reaper No Input/Automute

Hi,

I got a little problem on Mac. When using my Vst on Reaper the channel become "Automuted" and beside that I can't choose any input. Could it be a Core Audio problem ?

Thanks in advance

Did it work in Reaper on MAC before? Have you tried to Debug it? Comment out all/part of your DSP Loop?

That plugin works on Windows without particular problems.

So I've tried to comment parts to isolate where Reaper mute my plugin. It appears to be here :

Quote:
for (int s = 0; s < nFrames; ++s, ++out1, ++out2)
{
*out1 = (double(buf[s]) / max); //max = INT_MAX
*out2 = (double(buf[++s]) / max);
}
long *buf is assignated this way :

Quote:
//Interleave out1 & out2 to have one char buffer for my DSP
for (int s = 0; s < nFrames; ++s, ++in1, ++in2, ++out1, ++out2)
{
*out1 = *in1;
*out2 = *in2;
*buf = (*out1) * gain * max;
buf++;
*buf = (*out2) * gain * max;
buf++;
}
Do you know other DAWs which can load VST2/3 on OSX ?

[EDIT] Just saw I got this error in my logs : "REAPER[3135:63941] WARNING: The Gestalt selector gestaltSystemVersion is returning 10.9.6 instead of 10.12.6. This is not a bug in Gestalt -- it is a documented limitation. Use NSProcessInfo's operatingSystemVersion property to get correct system version number."
