Upload any audio file. Get BPM and musical key instantly. Use for samples, reference tracks, and anything you want to flip or layer.
Upload a sample and see every chord in the progression. Chord timeline shows when each chord hits. Export to recreate in the Piano Roll.
Enter your project BPM. Get the exact milliseconds for every note value. Copy and paste directly into Fruity Delay 3 or any third-party delay.
Enter any key and get all scale notes for 18 scales. Highlight notes in the Piano Roll to stay in key. Interactive piano keyboard visualization.
Look up the exact Hz value for any musical note. Essential for tuning 808s in the Sampler, identifying frequencies in the Parametric EQ, and analyzing audio.
Browser metronome with tap tempo and all time signatures. Practice playing at your project BPM before recording into FL Studio to lock in your timing.
The fastest way to go from a raw sample to a finished beat using BeatKey tools alongside FL Studio.
Upload your sample. Note the BPM, key (e.g. A minor), and Camelot code (e.g. 8A). Set FL Studio's tempo to match.
Upload the same sample to the Chord Finder. Get the full chord chart. Now you can recreate the progression in the Piano Roll or layer new chords on top.
Look up the target note in the frequency table (e.g. A2 = 110 Hz, C2 = 65.4 Hz). Calculate the semitone shift from your 808 sample's root note.
Look up the scale for your key. Enable Piano Roll ghost notes or use the scale highlighting to stay in key while writing melodies.
Enter your project BPM. Copy the ms values for the delay effects you want (e.g. dotted eighth = 321ms at 140 BPM).
How to use BeatKey tools with the FL Studio Piano Roll for better compositions.
Enable View > Helpers > Ghost Channels in the Piano Roll to see notes from other channels in gray. When you know your scale notes from scales.beatkey.app, you can visualize which Piano Roll cells to target.
Right-click any piano key in the Piano Roll to highlight that note row. Use this with the scale notes from scales.beatkey.app to visually mark in-key notes before you start writing.
FL Studio has a Chord Stamp tool in the Piano Roll (Stamp icon). After detecting chords from chords.beatkey.app, use Chord Stamps to quickly place the same chord voicings throughout your pattern.
In the Channel Sampler, use the MIDI note field to set what note your 808 sample is tuned to, then FL Studio will automatically pitch-shift it to match the Piano Roll notes. Check notes.beatkey.app for the root note Hz.
Always run your samples through BeatKey before importing. Knowing the BPM lets you use FL Studio's timestretching to match your project tempo without guessing. Wrong BPM = phasing artifacts.
If you DJ your own beats or build a set list, use the Camelot wheel at beatkey.app/camelot-wheel to plan which beats can transition smoothly based on key compatibility.
FL Studio is your DAW. BeatKey fills the gaps that FL Studio does not cover natively.

Upload your sample to BeatKey (beatkey.app). It detects BPM and musical key instantly using audio analysis in your browser. Once you have the BPM, set FL Studio's project tempo to match under Options > Project Settings. For samples already loaded, FL Studio also has a right-click "Detect tempo" option in the Channel Sampler, but BeatKey is more accurate for samples with complex rhythms.
Detect the track key with BeatKey, then look up the target note frequency at notes.beatkey.app/808-tuning-guide. In FL Studio, open the 808 sample in the Channel Sampler. Most 808 samples are pre-tuned to C, so count the semitones from C to your target note (e.g. A minor track = tune 808 to A = +9 semitones from C). Use the main pitch knob or the FIN (fine-tune) control in the Channel Sampler. Check notes.beatkey.app for the exact Hz value to verify you have the right pitch.
Open the BPM Delay Calculator at delay.beatkey.app and enter your project BPM. Get the exact milliseconds for the delay time you want (quarter note, dotted eighth, etc.). In Fruity Delay 3, click the "Time" knob area and switch to ms mode. Paste the value directly. Alternatively, Fruity Delay 3 has a Beat Sync mode where you can select note divisions directly. Use delay.beatkey.app to find which note division sounds closest to the ms value you want.
Upload your sample or reference track to the Chord Finder at chords.beatkey.app. It detects every chord in the audio and shows a chord timeline. You get chord names (e.g. Dm7, Gmaj7) with timestamps. Take those chord names and recreate them in the FL Studio Piano Roll manually, or use the Chord Stamp tool in the Piano Roll to place the same chord voicing at each timestamp.
Use the Scale Finder at scales.beatkey.app. Enter the key you detected with BeatKey and choose your scale type. You get all scale notes for that key. In FL Studio, you can right-click piano keys in the Piano Roll to highlight specific note rows - use the scale notes from scales.beatkey.app as a guide to mark which Piano Roll cells are in key before you start writing. The interactive Scale Visualizer at scales.beatkey.app also shows the notes on a piano keyboard.
The first tool every FL Studio producer needs. Upload any sample, get BPM + key + Camelot code instantly.
