I have a song and I want to use a whistle for a secondary melody it has. I chose the instrument Instrument Synth Classic / Sytrus / preset "Angelic whistle". The problem is the sound is too sharp I guess, and it deafens you when you listen it. I've heard songs where they used whistles and they werent annoying at all. How can I set that instrument in FL Studio so it doesnt deafen you when you listen it?

    You can also use a channel EQ to reduce the high frequencies. Dec 8, 2022 at 16:17

The "Angelic whistle" preset is simply a sine wave with unison, vibrato, and reverb. EQ will not do anything useful. Turn the volume down. Consult the FL Studio manual if you are not familiar with the volume controls.

  • I did that, I turned the volume down for that sound, it seems to be ok
