6 essential browser tools that work alongside Logic Pro X. Detect BPM and key from samples, find chord progressions, calculate delay times for Tape Delay, look up scale notes for Piano Roll Scale Lock, and tune your 808s.
Upload any audio file. Get BPM and musical key instantly. Use for samples, reference tracks, and anything you want to flip or layer in Logic.
Upload a sample and see every chord in the progression. Chord timeline shows when each chord hits. Use to populate Logic Pro chord tracks.
Enter your project BPM. Get exact milliseconds for every note value. Copy directly into Logic Pro delay plugins in ms mode.
Enter any key and get all scale notes for 18 scales. Use to configure Logic Pro Scale Quantize and highlight Piano Roll note rows.
Look up the exact Hz value for any musical note. Essential for tuning 808s in Quick Sampler, identifying EQ frequencies, and analyzing audio.
Browser metronome with tap tempo and all time signatures. Practice at your Logic project BPM before tracking live instruments or vocals.
The fastest way to go from a raw sample to a finished track using BeatKey tools alongside Logic Pro.
Upload your sample. Note the BPM, key (e.g. C minor), and Camelot code (e.g. 5A). Set Logic's project tempo in the LCD display to match.
Upload the same sample to Chord Finder. Get the full chord chart with timestamps. Now recreate the progression in Logic's Piano Roll or Chord Track.
Look up the target note in the frequency table (e.g. C#2 = 69.3 Hz, A2 = 110 Hz). Load your 808 in Quick Sampler and set the root key field to match.
Look up the scale for your key. Enable Scale Lock in Logic's Piano Roll to constrain MIDI input to scale notes while writing melodies.
Enter your project BPM. Copy the ms values for the delay effects you want. In Logic's Tape Delay or Echo, switch to ms mode and paste.
How to use BeatKey tools with Logic Pro features for better production results.
Logic Pro's Smart Tempo analyzes audio for tempo. BeatKey complements it by also giving you the musical key, Camelot code, and working on unreleased tracks with unusual grooves that trip up Smart Tempo.
Logic Pro's Piano Roll has a Scale Quantize dropdown. Once you know the scale from scales.beatkey.app (e.g. A Dorian), match it in Scale Quantize to lock MIDI input to in-key notes only.
Logic's Quick Sampler has a Root Key field. If your 808 sample is tuned to C, set Root Key to C and Logic auto-pitches it to any Piano Roll note. Verify 808 tuning with notes.beatkey.app.
Logic Pro's Chord Track lets you define chords for a project and follow regions. After detecting chords with chords.beatkey.app, populate the Chord Track to drive Smart Strings or Arpeggiator.
Always run samples through BeatKey before importing to Logic. Knowing the BPM lets you set Flex Time mode correctly and avoid phase issues from incorrect transient detection.
Use BeatKey to get the Camelot code for each sample and reference track. Combine loops and samples with compatible Camelot codes (same number, adjacent letters/numbers) for harmonic consistency.
Logic Pro is your DAW. BeatKey fills the gaps that Logic does not cover natively.
| Task | Logic Pro | BeatKey Tool |
|---|---|---|
| Detect BPM of a sample | Smart Tempo (tempo detection from audio) | BeatKey - BPM + musical key together, faster for single files |
| Find the musical key of a sample | Not built in for audio files | BeatKey - automatic key + Camelot code |
| Find chords in a sample | Not built in | Chord Finder - full chord timeline |
| Populate the Logic Chord Track | Manual chord entry only | Chord Finder - detect chords, then enter into Chord Track |
| Tune 808 to track key | Quick Sampler root key (manual setup) | Note Freq Calculator - exact Hz per note, 808 tuning guide |
| Set delay ms to match BPM | Tape Delay / Echo note divisions or ms | Delay Calculator - exact ms for any note value at any BPM |
| Look up scale notes | Piano Roll Scale Quantize (limited scale list) | Scale Finder - 18 scales including modes, all 12 keys |
| Calculate reverb pre-delay | Not built in | Delay Calculator - BPM-synced pre-delay values |
| Identify Camelot code | Not built in | BeatKey - Camelot code in every result |
| Transpose a chord sheet | Not built in | Chord Sheet Transposer at chords.beatkey.app |
| Practice at project tempo | Built-in metronome | Metronome at beatkey.app/metronome with genre BPM guide |
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 Logic's project tempo in the LCD display at the top of the main window. Logic also has Smart Tempo which detects tempo from audio regions, but BeatKey is faster for single files and gives you the musical key at the same time.
Detect the track key with BeatKey, then look up the target note frequency at notes.beatkey.app/808-tuning-guide. In Logic Pro, load your 808 sample in Quick Sampler. Set the Root Key field to match the tuning of your 808 sample (most 808s are tuned to C). Logic will then automatically pitch-shift the 808 to any note you play in the Piano Roll. Use notes.beatkey.app to verify the exact Hz value of your target note.
Use the BPM Delay Calculator at delay.beatkey.app. Enter your project BPM and get exact milliseconds for every note value (quarter, eighth, dotted eighth, sixteenth, and more). In Logic's Tape Delay, switch to ms mode by clicking the note division display and selecting ms. Paste the value directly. Echo and most third-party delays work the same way. Logic delay plugins also support note division sync (1/4, 1/8D, etc.) so you can use the note division reference from delay.beatkey.app.
Upload your sample to the Chord Finder at chords.beatkey.app. It detects every chord in the audio and shows a chord timeline with chord names and timestamps. Take those chord names and recreate them in Logic's Piano Roll. Logic Pro's Chord Track feature lets you attach chord symbols to your project timeline. Once you have the chords from Chord Finder, populate the Chord Track to drive Smart Strings, arpeggios, or MIDI FX.
Use the Scale Finder at scales.beatkey.app. Enter the key you detected with BeatKey and choose your scale type (Natural Minor, Dorian, Mixolydian, etc.). You get all scale notes for that key. In Logic's Piano Roll, use Scale Quantize from the dropdown in the toolbar to constrain MIDI input to your chosen scale. The interactive Scale Visualizer at scales.beatkey.app also shows the notes on a piano keyboard so you can see the exact keys to play.
The first tool every Logic Pro producer needs. Upload any sample, get BPM + key + Camelot code instantly.
