It has been observed that some waveforms aren't centered around the 0 baseline. A DC filter could be used to remove this offset.

If a note is released and the sustain pedal is active, maybe the key can be half-highlighted?

Describe the bug
One of the synthesizer playability options is using the computer keyboard. Certain letters are matched to certain notes (A-L plus some letters from the above line), and pressing one of the letters triggers the synthesizer to play a certain note. The problem is that when the keyboard language is set to another language (in my case Greek) it stops responding.

*To Reproduce

Hi,

I think that is not good to store the frequencies of the notes since the formula "note x 2 N/12" would give the frequency and you might pitch the base frequency 440 (not everybody use 440 as base frequency )
