Hello IPlugers! I just put SOUL default patch into the IPlugSOUL project, and there is an error:

 ![Screenshot 2021-06-23 at 10.16.20 PM](https://global.discourse-cdn.com/free1/uploads/iplug2/original/1X/fc8a94da0863d1ef43dd78e672e4157ce865f4be.png)  
I can’t find how to fix it 😭

I guess the soul patch has no inputs? In which case you need to change the channel IO/make the iPlug2 project an instrument.

> <https://github.com/iPlug2/iPlug2/blob/master/Examples/IPlugSOUL/config.h#L18>

→ #define PLUG\_CHANNEL\_IO “0-2”

> <https://github.com/iPlug2/iPlug2/blob/master/Examples/IPlugSOUL/config.h#L21>

→ #define PLUG\_TYPE 1
