Free Tools for Cubase Producers
Steinberg Cubase is a professional DAW with powerful MIDI tools and audio editing. It doesn't detect BPM from raw audio files, identify musical key from samples, detect chord progressions, or calculate BPM-synced delay in milliseconds. BeatKey fills those gaps, free, in any browser, no account required.
What Cubase Doesn't Include
Cubase can set tempo from clips but requires manual verification with a dedicated analyzer first
Cubase's Chord Track can follow audio but doesn't output key + Camelot code for DJ/producer workflow
No built-in tool to detect what chords are in a drum break, loop, or sample
Delay plugins have note-division mode but no quick-reference calculator for switching to ms mode
Scale Assistance mode highlights notes but you still need to know which scale to select
No built-in Hz reference for tuning 808s in the Sampler Track to specific musical pitches
6 Free Tools That Work Alongside Cubase
Upload any sample, loop, or stem. Get BPM, musical key, and Camelot code instantly.
Cubase use: detect BPM before "Set Definition from Tempo" to verify Cubase's auto-detection. Detect key before setting the Cubase Chord Track root key so Scale Assistance highlights the right notes.
Visual harmonic mixing chart. Find compatible keys for layering samples in Cubase.
Cubase use: after detecting keys with BeatKey, use the Camelot Wheel to plan which samples and loops are harmonically compatible. Adjacent Camelot numbers mix cleanly in Cubase's Arranger Track.
Detects chord progressions from any audio file. No login, no limits.
Cubase use: detect chords in a sample, then enter the progression into the Cubase Chord Track. Other instruments set to follow the Chord Track will automatically adapt their voicings to match the harmonic movement.
Calculates exact ms values for BPM-synced delay. Covers every note value.
Cubase use: open StereoDelay, PingPongDelay, or any delay plugin. Switch from note-value to ms mode. Enter the exact ms from the calculator to lock delay repeats to your project tempo perfectly.
Scale notes for all 18 scale types in all 12 keys. Includes all 7 modes.
Cubase use: after BeatKey detects your key, look up the scale at scales.beatkey.app and configure Cubase Key Editor Scale Assistance mode. Works for all modes Cubase supports: Major, Minor, Dorian, Phrygian, Lydian, Mixolydian, Locrian.
Hz values for every note, MIDI chart, 808 tuning guide, and chromatic tuner.
Cubase use: tune 808 bass hits and pitched samples using the Sampler Track. Match the root note to the exact Hz from notes.beatkey.app. C1 = 32.7 Hz, D1 = 36.7 Hz, G1 = 49.0 Hz for common 808 tunings.
Sample Flip Workflow in Cubase
The Cubase Sampler Track and MediaBay make Cubase one of the best DAWs for sample-based production. Here is the complete BeatKey-assisted workflow:
Step 1: Detect BPM and Key
Drop the sample into BeatKey (beatkey.app). Get BPM, key, and Camelot code in seconds. No Cubase project needed yet.
Step 2: Set Project Tempo
Create a new Cubase project. Set the project BPM in the Transport Bar to match the sample BPM from BeatKey. Right-click the audio event and use "Set Definition from Tempo" to apply AudioWarp correctly.
Step 3: Detect Chord Progression
Upload the sample to chords.beatkey.app. Identify the full chord progression. Add the chords to the Cubase Chord Track so other instruments follow the harmonic movement.
Step 4: Set Scale Assistance
Open the Cubase Key Editor. Enable Scale Assistance mode. Look up the detected key at scales.beatkey.app and select the matching scale and root note.
Step 5: Tune 808 or Bass
Load your 808 into the Cubase Sampler Track. Look up the target note Hz at notes.beatkey.app and set the root note in the Sampler Track to tune the 808 correctly to the key.
Step 6: Set BPM-synced Delay
Open StereoDelay or PingPongDelay in Cubase. Switch to ms mode. Get exact ms values from delay.beatkey.app and enter them for delay that locks to your project tempo.
6 Cubase Workflow Tips with BeatKey
Chord Track + BeatKey Key Detection
Cubase's Chord Track is one of its most powerful features. Detect the key in BeatKey, then set the Chord Track root key. All instruments following the Chord Track will automatically voice their chords in the correct key.
AudioWarp BPM Verification
Cubase's AudioWarp can misdetect tempo on complex grooves or samples with swing. Always verify with BeatKey first. If the detected BPM is double or half what AudioWarp shows, the warp algorithm will stretch incorrectly.
Sampler Track Root Note Tuning
Load any 808 or pitched sample into the Cubase Sampler Track. Use notes.beatkey.app to get the exact Hz of your target root note. Compare it to the sample's original pitch to calculate the correct transpose amount in semitones.
Scale Assistance Mode Setup
Cubase Key Editor has Scale Assistance that highlights notes in your chosen scale. After BeatKey detects your key, look up the full scale notes at scales.beatkey.app. Match the root and scale type in Cubase's Scale Assistance settings.
Variaudio Pitch Correction Key Setup
Cubase's VariAudio pitch correction works best when it knows the project key. Use BeatKey to detect the key of any vocal or lead line, then set the Cubase Chord Track key so VariAudio's snap-to-scale feature corrects to the right notes.
Harmonic Mixing with MediaBay
Tag all your samples with Camelot codes (detected by BeatKey). Use MediaBay's user attributes to filter by Camelot number when browsing loops. Adjacent Camelot numbers (e.g., 8A and 9A) layer cleanly in any Cubase Arranger Track.

Frequently Asked Questions
How do I find the BPM of a sample in Cubase? ▾
Upload your sample to BeatKey (beatkey.app). It detects the BPM and musical key instantly in your browser. Once you have the BPM, right-click the audio event in Cubase and use "Set Definition from Tempo" or manually enter the detected BPM in the Transport Bar. For Cubase's AudioWarp and time-stretching to work correctly, the project tempo must match your sample BPM.
How do I find the key of a sample in Cubase? ▾
Cubase has Chord Track analysis but it requires importing the audio into the project. BeatKey (beatkey.app) lets you detect the key before import, instantly, by uploading any audio file. You get BPM, key, and Camelot code in seconds. Once you know the key, set it in the Cubase Chord Track so instruments and Scale Assistance mode in the Key Editor highlight the correct notes.
How do I calculate BPM-synced delay in Cubase? ▾
Use the BPM Delay Calculator at delay.beatkey.app. Enter your Cubase project BPM and get exact milliseconds for every note value. In Cubase, open a delay plugin (PingPongDelay, StereoDelay, or any third-party delay) and switch from note-division mode to ms mode. Enter the calculated value. For the rhythmic dotted eighth delay, use the dotted eighth column. For slapback, use the eighth note column (50-120ms).
How do I find chords in a sample for Cubase? ▾
Upload the sample to the Chord Finder at chords.beatkey.app. It detects the full chord progression from any audio file. Once you have the chords, add them to the Cubase Chord Track. Instruments following the Chord Track will adapt to the harmonic movement. This workflow is especially useful for sample flipping and building new arrangements over existing loops in Cubase's Arranger Track.
What scales work with Cubase's Scale Assistance mode? ▾
Cubase's Key Editor has Scale Assistance mode that highlights notes in a selected scale. Look up any scale at scales.beatkey.app to find all notes for any root key and scale type. BeatKey covers 18+ scale types including all 7 modes, pentatonic, blues, harmonic minor, melodic minor, and exotic scales. Match the root key detected by BeatKey and choose the scale type to configure Cubase Scale Assistance correctly.
