Problems using gpios and pisound

Hi, I’m using Pisound with SamplerBox, and I’ve added some extra buttons. I tried to avoid the GPIO pins that Pisound uses. I bought a GPIO splitter so I can connect both the Pisound and my breadboard. However, when I run SamplerBox and try to use the buttons, they don’t work—they only work when the Pisound isn’t connected. So my question is: does Pisound actually leave some GPIO pins unused? For example, I use GPIO 13 to change presets, and when I start SamplerBox it goes into an infinite loop as if the button is always pressed. GPIO 19, which I use as the select button, also seems to loop. There are other gpios having the same problem. how can i fix this?

Hi, those pins are used by Pisound. Pick from the available GPIO pins as listed in the table at https://blokas.io/pisound/docs/general-specifications/#pinout-of-pisound-header.
