When to Use BeatKey Instead
Tuning 808s in your DAW
Look up the exact Hz for any note, then pitch your 808 sample to match. The 808 Tuning Guide shows the full C1 to B3 range with DAW-specific pitch instructions for FL Studio, Ableton, and Logic Pro.
EQ and frequency identification
The EQ Frequency Chart shows which notes correspond to which EQ bands. Use it to notch resonances, boost presence, or identify the musical note causing a problem frequency in your mix.
Programming MIDI with note numbers
The full MIDI note chart covers all 128 notes (C-1 to G9) with MIDI numbers, Hz values, and the GM drum map. Essential for drum programming, automation, and debugging MIDI data in any DAW.
Choosing keys for vocalists
The Vocal Range Chart shows all 7 voice types with Hz ranges and MIDI notes. Detect the track key with BeatKey, check if it fits the vocalist's range, and transpose if needed using the Key Transposer at beatkey.app/key-transposer.
