It works now, thank you so much, David.

@d-healey good question. just tried. The problem exists with single mics as well.

And...... YOU WERE RIGHT!
It works now, thank you so much, David.

The original wav files are in a different folder on my hd...
I zipped the full project folder as it is. I only removed the exported map.ch1 files I had exported in the root folder.

@d-healey here you go.. thank you so much

No, I started an empty project, added the sampler, loaded the samples, no multimic. Created a minimal gui.
If I do the same thing with a sinewave it works.

@d-healey
My LinkOSX file says:
/Users/sergiomarchesini/Music/My Company/vsttest/Samples

But, as I said, if I use Reaper's virtual midi keyboard I hear the sounds just fine so I think there is no problem with the sample folder path.

@d-healey good question. just tried. The problem exists with single mics as well.

One more element: if I compile a simple SineWave Generator things work fine. Could it somehow be connected to the samples being multi mic?

I re-exported and I realised the following:
The problem seems to be connected to the midi channel.
I have an external midi controller I use to play my VSTi.
In Reaper, if I use the virtual keyboard the plugin plays correctly, while if I play with the external keyboard it does not.
:O

I cross checked with another VSTi, and with it I have the expected behaviour (both external controller and virtual keyboard work)
I see midi activity in reaper when I use the controller.
I tried changing channel on my controller but nothing.
Is there any setting I need to make before exporting to tell my sampler to just listen to whatever midi port/channel I route to it?

Thank you very much, BTW Hise rocks.

oops sorry
