AllGoRhythmics

Read full description

AllGoRhythmics is a professional rhythm-notation tool for musicians, students, teachers, and composers who want to SEE the rhythm — not just hear it. Most metronome apps give you a click. AllGoRhythmics gives you a living score. Every pattern you build renders in real Bravura music notation — the SMuFL standard used by professional engraving software — with intelligent rest merging, beam grouping, tuplet brackets, and an animated comet playhead that tracks your place through the bar. • REAL MUSIC NOTATION Notes, rests, beams, and brackets render with the Bravura font. Smart rest merging keeps the score clean: four sixteenth rests collapse to one quarter, three to a dotted quarter, and so on. Dorico-style compact spacing keeps even dense bars readable. • TUPLETS, ANY RATIO Place any tuplet straight on the dial — triplets, quintuplets, septuplets, and beyond — engraved with proper brackets and X:Y ratio labels. Nest a tuplet inside a tuplet member when you need it. Notation and playback follow exactly what you build. • LIVE EDIT, ZERO FRICTION Tap any beat to silence it. Drag the time signature to change meters. Tap-tempo a feel by hand. Edit a pattern during playback — your changes land on the next loop. • PROFESSIONAL TIMING & SOUNDS Sample-accurate audio scheduling on a high-precision clock and AVAudioEngine — no drift, no jitter. Choose from eight sound sets, from claps and percussion to marimba, piano, 808, and a clean sine. • TRAINER + PRACTICE LOG (free for everyone) Tap along and get scored against any rhythm, with adjustable tolerance and a results summary. Every session is logged automatically with aggregate stats and a 7-day accuracy trend. • RHYTHM GENERATORS Binary Rhythms builds every 2ⁿ on/off permutation of a beat as one playlist, instantly. The new AMD (Additive / Aksak) generator builds aksak meters from 2s and 3s on a clean dotted grid at a steady pulse — a serious tool for odd-meter practice. • PLAYLISTS, BUILT FOR PRACTICE Chain presets into practice sessions. Lock BPM or RPM across the whole playlist, set per-entry repeats, and play in order, shuffled once, or reshuffled every loop. Sort your playlists, Select-All when adding presets, and Export or Import a whole playlist as a single shareable file. • EXPORT AND SHARE Render any pattern to MIDI or audio and drop it straight into your DAW or notation software. Share presets and whole playlists as files over AirDrop, Messages, or Files — and import what others send you. FREE — full power, no trial timer • All notation, comet playhead, eight sound sets, and audio • Trainer mode and Practice Log, unlimited • Time signatures and subdivisions up to 5 • 5 presets, 2 playlists of 5 entries each • 2 Binary and 2 AMD generations; 5 MIDI and 5 audio exports UNLOCK PRO — one purchase, forever • Time signatures up to 32 and subdivisions up to 16 — quintuplets, septuplets, odd meters • Tuplets with any X or Y above 5, including nested tuplets • Unlimited presets and playlists • Export and import whole playlists as shareable files • Unlimited MIDI and audio export • Unlimited Binary and AMD generation • iCloud sync across your devices WHO IT'S FOR Drummers working through Stick Control or Syncopation, jazz students feeling odd meters, composers sketching rhythms, teachers presenting in class — anyone who's wanted a metronome that shows what they're playing.

One developer, no ads, no subscriptions, no tracking. Buy it once, own it forever. Privacy policy: https://www.pujamusic.com/privacy Support: support@pujamusic.com

IDOUDO

Read full description

Read notes fast in movable Do. Name the notes you hear. Sing famous melodies in all 12 keys. IDOUDO is a solfège app for practicing all three, a few minutes a day — for jazz and pop sessions, playing by ear, and reading parts in choirs and ensembles, so a key change never throws you off. Ear Training and Melody Shadowing are new in version 1.1. Answer each displayed note using the Do, Re, Mi, Fa, Sol, La, and Ti buttons. When the key changes, the same position on the staff has a different movable-Do syllable. Practice this essential movable-Do skill repeatedly in all 12 keys. In addition to treble and bass clefs, IDOUDO supports the alto clef, a feature rarely found in music practice apps. It is useful both for the daily practice of musicians who read alto-clef music and for those who want to become more fluent in every key as they expand into jazz and pop sessions. If you are just beginning to read staff notation, start with the key of C. In C, Do–Re–Mi and C–D–E correspond directly, so you can also use IDOUDO to practice the fundamentals of reading standard notation. DRILLS Reading • Single notes: 1 Note, 2 Notes • 1 Triad • 1 Seventh Chord Listening • Ear training: 2, 3, and 4 notes • Melody Shadowing: Major set 1, Major set 2, Minor set 1 EAR TRAINING After a Do-Mi-Sol chord, listen to the notes and name them in movable Do. The answer buttons form a "staircase" from low on the left to high on the right, so you answer the pitch height too. A foundation for playing by ear. MELODY SHADOWING Hum short melodies from famous pieces in movable Do while the key changes. There is no scoring. Each time the key changes, an I–ii–V–I cue sets the new key's Do in your ear, and Do keeps sounding as the accompaniment while you sing. Songs: Twinkle Twinkle Little Star, Canon, When the Saints Go Marching In, Ode to Joy, Swing Low, Sweet Chariot, Furusato, Sakura Sakura, Fate (Symphony No. 5), and Kojo no Tsuki (minor keys are read from La). It is also good practice for the pentatonic and major scales. KEY FEATURES • Practice in all 12 keys • Treble and bass clefs, plus the alto clef used by viola • Note ranges for piano, guitar, violin, viola, cello, wind instruments, voice, and more • Beginner, Intermediate, Advanced, and Custom ranges • Fast 10-question rounds • Average response time, mistakes, and personal-best records • Pin the drills you practice to the top of Home • Built-in know-how, including how to practice each drill • Up to 50 local profiles • Shareable result cards and progress • Light and Dark Mode READ CHORDS WITH MOVABLE DO For triads and seventh chords, answer chord tones from bottom to top. The result also shows the chord symbol and Roman-numeral degree name. NEW TO STAFF NOTATION? The in-app Getting Started with Staff Notation guide explains why the key of C is a good place to begin, includes a quick note-reference chart, and shows how to use the app for classical music, ensemble playing, and sessions, with a suggested practice path. PRICING Keys C and G are free in every drill. The other 10 keys can be unlocked in either of two ways: • A one-time in-app purchase for each drill • All Drills, an auto-renewable subscription (monthly with a 1-month free trial, or yearly) that also includes drills added in the future. Prices are shown in the app and on the App Store. The subscription renews automatically at the same price unless canceled at least 24 hours before the end of the current period. Payment is charged to your Apple Account. Manage or cancel it in Settings > [your name] > Subscriptions. The free trial is available once, on the monthly plan; cancel at least 24 hours before it ends and you won't be charged. No ads are displayed, and no account registration is required. Profiles and practice records are stored on your device. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
