Start learning today with the iDrumTune app and the drum tuning masterclass lessons. Lessons 1-5 can be accessed free of charge at www.learndrumtuning.com, purchasing the iDrumTune app unlocks access to all lessons and interactive learning features. "an invaluable aid not only for drummers but also studio engineers and producers" - Sound on Sound Magazine "I can’t recommend this app highly enough ... for the money, it is indispensable. It's simple, accurate, looks good, and the tuning information is worth the cost of the app alone." - www.mikedolbear.com “***** I never knew I could have this much fun tuning drums!” – Adamrod (App Store review) “***** Just tuned my first drum and this app is awesome!” – bburt85 (App Store review) “***** Buy this app if you are a drummer!!!” – Lildrummerboy (App Store review) The original and most innovative drum tuning app - iDrumTune brings an unrivalled accuracy and a host of unique features for assisting with drum tuning. Built by world experts in drums and musical acoustics, iDrumTune is backed up by an integrated, progress-tracked AES-published masterclass on Drum Sound and Drum Tuning. iDrumTune includes the following features: Pitch Tuning – to make your drums sing and allow you to play musical phrases around the kit. Lug Tuning – to ensure that the drumhead is evenly tuned and gives a smooth and warm tone. Resonant Head Tuning – to allow you to be sure that the two heads are working together and giving rich overtones. In-App Coach – an intelligent on-screen assistant guides you through the tuning process in real time, helping to prevent false readings and guarantee success on your very first try. Spectrum Analyzer – so you can really start to understand what frequencies are excited and heard when playing the drums. Native LEARN Masterclass – our complete, world-class drum acoustics masterclass integrated natively into the app's LEARN tab, allowing you to track progress as you tune. Ear-Tuning Development – a responsive, keys-based tone generator to help you develop the active listening skills required for unassisted ear-tuning. Drum Kit Presets & Cloud Sync – save and load your favourite custom kit configurations via the interactive Drum Kit Designer, synced cross-platform to recall setups in seconds. iDrumTune is the first and by far the most intelligent and accurate system for analysing drum sounds and assisting tuning – developed by drummers, music producers and acoustics research Professors. iDrumTune provides you with a measurement of the drumhead vibration frequency; in Pitch Tuning mode, you simply hold your device over the center of a drum, about 2-4 inches away, then strike the drum in the center. iDrumTune shows the recorded sound waveform in real time and gives the strongest frequency recorded. There is also a tuning indicator bar which shows the drumhead tuning relative to musical notes, so iDrumTune can be used to ensure that your drums are in key with each other or the song you are playing. A frequency spectrum view also allows more detailed analysis. Our updated under-the-hood algorithms optimise detection between center and edge strikes, whilst Lug Tuning mode offers the simplest and most innovative method for tuning an even frequency response at the lug positions on the drumhead. Drum Tuning isn’t easy, and drums don’t respond exactly the same way every time you hit them. For that reason, it's valuable to know a little about the science of drum tuning. iDrumTune includes the complete, natively integrated drum acoustics masterclass in the LEARN tab to help you get the best from the app and become an expert drum tuner! Learn with iDrumTune. No more tuning in the dark.

Drum Charter is a professional drum notation app for creating, editing, and playing drum charts using an intuitive text-based format. Perfect for drummers, music teachers, and composers who need a fast, distraction-free way to write drum patterns. KEY FEATURES * Text-Based Notation Simple ASCII symbols represent drums: 'x' for hi-hat, 'o' for snare, 'Q' for kick. Triplet notation with the ³ symbol for advanced rhythms. Fast to type, easy to read. * Staff Notation Read the same chart as real drum notation on a five-line staff: noteheads per instrument, beams, rests, triplets, flams, ghost notes, repeat signs and rehearsal marks. Switch per song with [notation: staff] or live in Concert Mode. * Smart Symbol Palette Context-aware: symbols that don't fit the current line are greyed out. * Real-Time Audio Playback High-quality drum sounds powered by FluidR3_GM soundfont. Hear patterns instantly with professional MIDI-based playback. * Flam & Ghost Notes Two expressive symbols for snare: Flam for quick grace notes before the main hit, Ghost for subtle quiet notes. Perfect for Jazz, Funk, and dynamic playing. * Lyrics Mode Create charts without drum notation - just lyrics, chords, and cues. Perfect for multi-instrumentalists with mixed setlists. Section headers in teal, cue lines in gray. Embedded drum bars automatically detected. Chord symbols highlighted in blue. * PDF Export Export as PDF — as the character grid, or as engraved staff notation on A4. Works on iPhone, iPad and Mac. * MusicXML Export Export to MuseScore, Sibelius, Finale and more — with triplets, repeats, flams, ghost notes and rehearsal marks. * MIDI File Export Export as Standard MIDI Files with two-voice layout. Configurable stem grouping. Import into any DAW. * Practice Mode A full-screen practice room for your e-drums. Loop any range of bars, with an optional count-in. Every hit you play appears on the notation, colour-coded by accuracy, with missed notes marked. A calm readout shows whether you rush or drag and how even you are - the two things that actually help. Output latency is compensated automatically. Repeat counts are honoured, so you practise the phrase as written. * Concert Mode with Foot Pedal Full-screen performance view with large custom font (10-40pt). Turn pages hands-free with arrow keys, Bluetooth page turners or MIDI foot pedals. Your setlist is the folder of the current song. Metronome click, beat grouping, play and skip controls. Native macOS fullscreen. Multi-column lyrics with [columns: N]. * Multi-Time Signature Support Full support for 4/4, 3/4 (Waltz), and 6/8 (Compound Time). UI picker for quick time signature changes. * Swing & Shuffle Support Authentic Jazz/Blues feel with standard swing notation. Write "Shuffle" for classic 67% swing, or specify 50-75%. UI button with 5 presets. * BPM Control via Metadata Set tempo in the chart with [140 BPM], 60-200 BPM. * Smart Bar Management Auto-numbering up to 999 bars. Repeat notation (4x) for efficient charting. Move bars up/down. Section headers for song structure. * Combination Symbols Three symbols for simultaneous Snare+Tom hits: p (Snare+Tom1), d (Snare+Tom2), g (Snare+FloorTom). Perfect for complex fills. * Multi-Column Export 2, 4, 6 or 8 bars per line, optionally with spaces instead of rests (Logic Pro). * Universal App - iPhone, iPad, Mac Native experience on all devices with seamless iCloud sync. Start on iPhone, continue on iPad or Mac.
