I can hear sound effects on Pd-0.55-2 but I can't hear sound effects on my swift code .
new-this.pd

[PdBase sendFloat:26 toReceiver:@"revValue"];
I read from swift revValue and send to parameter >>> 16

maybe I need to send another value ? or I have another problem

@erhandemirci Sorry, I know nothing at all about Swift.
After a quick search on the internet it seems that no externals can be used with swift..... so only objects contained within a basic install of Pd (vanilla) will work.

The only objects I can see that will not work are the filter externals...... [lowpass] etc.
That means unfortunately that you will need to calculate the parameters for [biquad~]
