Hello, and thanks for your time.

My name is Agustin Riolfo and I am developing a music software to make guitar effects. I found that your software is suitable for my application.

I won´t sell the software but I would like to have a Patreon account so that if some fans would like to, can contribute with me.

The question is, being that the software would not be sold and that would only be donations, is there any problem on having a Patreon account? Moreover, if I use blocks like [expr] or [expr~] that use a GPL licence (as far as I know), would donations through Patreon be a problem??

Thanks in advance
