So I've been watching the YT vids for the upcoming 3.0 version of the app and I've noticed something about the filters (high/low) pass, in this video 1BITDRAGON 3.0 preview: Chiptune instruments + Modulation wheel.

I can see that there are 3 different images underneath the filter grid. What exactly are these and how exactly will they effect the music we make?

These buttons  allows you to activate filters: high pass, medium pass and low pass filters. A high pass filter is good for getting rid of low sounds, and a low pass filter is good for getting rid of high sounds. It’s quick, easy and fun to experiment with 🙂
