Production Tools
Essential tools for producers and mixing engineers. Calculate BPM relationships, delay times, dB values, sample rates, and explore every key and scale.
Every scale and mode in every key, with intervals and diatonic chords, plus a timed drill that asks you to name any degree of any scale.
16-step sequencer with 8 synth sounds, swing control, and built-in presets. Program beats right in your browser.
Build chord progressions by clicking diatonic chords, put a bass line under them, set your key and tempo, then play them back or export both as MIDI.
Create melodies in any key and scale. Tap notes on the piano or generate random patterns in major, minor, pentatonic, blues, and more.
Tap to find your tempo, convert BPM to milliseconds for delay and reverb, get sidechain release times and LFO rates for any subdivision, and see how long a bar or section runs in any meter from 2/4 to 7/8.
Sync your delay effects perfectly. Enter your BPM and note value to get the exact delay time in milliseconds.
Convert between decibels, voltage, and power ratios. Essential for understanding audio levels and gear specs.
Understand sample rate and bit depth. See how audio quality changes at 44.1kHz vs 96kHz vs 192kHz.
Enter your tempo and get tempo-synced reverb pre-delay in milliseconds, plus decay times that end before the next beat or bar instead of smearing into it.
