For band directors: one assignment, every instrument, now one tap from the first screen. Choose "The whole band — concert pitch" and every student opens it in their own key: for F concert, a trumpet reads G, an alto sax D, a flute F. Every instrument now plays in its own voice. Tenuto is the new default articulation, and with Swing on quarter notes, beats 2 and 4 are accented.

New: Play Along, every maqam in all 12 keys, and cleaner sounds. Play Along: 14 short blues pieces from the author's own tenor saxophone solo, sung, with the notation scrolling in your key for 69 instruments. Slow the tempo, loop any bars, and print your part. The pieces stream from thewholehorn.com, so they need a connection. Skip a Step is free; the other thirteen are part of the Full Studio. Maqamat: every maqam now plays in all 12 keys. The original key comes first and stays marked, with one tap back to it. Sound: the click on Pure is gone, and so is the tick at the start of a note. Harp and piano no longer sound alike, and organ and celesta have their own sounds. Fast notes now speak on strings, voice and flute, and the sounds are more even in loudness. Drums: the groove now plays right through whole notes and half notes, in all 45 styles. Rockabilly and Ska have their backbeat again at "Backbeat only". When the drum volume is at zero, the Sound panel says so.

Every note in the octave you really play. Trombone and the other bass-clef instruments now read one- and two-octave exercises on the staff, in the octave they play, never an octave low under a small 8. Guitars, ouds and the buzuq are written where players read them. Every exercise, Extend range included, stays inside your instrument's real range.

All 12 keys: every key now ends on its own tonic. When you run a scale through all twelve keys, each key finishes on its own tonic, held to the end of the bar, before the next key starts. Also fixed: the concert note names on transposing instruments, the range named above the staff, and the teacher-assignment line on the purchase screen.

Ear training: eight listening games Higher or Lower (pitch direction, down to 15 cents), Drop, Name It, Lock-On (tune until the wobble stops), Echo (sing it back, microphone optional), Half-Flat (quarter tones), Maqam Map (Arabic maqamat, up to all 22) and Chord Colours, from triads to jazz voicings from real books: drop 2, rootless, quartal, upper structures. After a miss you hear your answer and the right one side by side. Today's ear is a short daily session chosen from what you can do, and the ear map shows your progress. Everything stays on your device. Blues bass lines: Thomas Hornig's own 12-bar walking bass in all 12 keys, for 69 instruments. F is free. Practice: loops land the tonic on beat 1 of the bar, and beginner patterns stay within the notes you choose. "All 12 keys" starts from any key. Choose the starting note in the chromatic studio. Each module shows only its own options. Teachers: assign any module, maqam or ear game. It opens for the student, and practice time counts correctly.

Fixes the starting octave on guitar, bass and oud. On seven-string and eight-string guitar, classical, acoustic and electric guitar, bass, and Arabic oud, a scale could begin an octave above where it should — starting mid-instrument instead of at the bottom of the playable range. It now starts where the instrument starts. Wind and brass are unchanged. On those instruments, beginning a low scale on the central tonic rather than the lowest note is deliberate — the bottom register is the hardest place to start — and that behaviour is exactly as it was.

The first overtone — fundamental to the octave — is now free to try on every instrument. Thirty of the written lessons can now be listened to, read aloud, including the instrument-specific quarter-tone notes and both satellite apps. Three minor scales — natural, harmonic and melodic — each rooted on the key you choose. A new lesson, "The first week", on posture, hand position and embouchure. Maqam Rast is now free, so you can hear what a quarter tone actually is before deciding anything. Play is now available inside the Setup and Sound panels, so you can hear a change without leaving them. A number of display fixes: a panel that could cover the one beneath it, note names shown twice on octave-transposing instruments, several controls whose text was being cut off, and the section heading now always matches what is actually loaded.

New in this version: • The 22 Arabic maqamat, with real quarter tones — rast, bayyati, hijaz and the rest, each with its traditional tonal centre and bilingual degree names. They live in one place: the Maqam theory module inside The Full Studio. • Notation now writes every accidental explicitly and uses no key signatures, so nothing has to be carried in your head mid-exercise. • Overtone guidance is now written separately for brass and for saxophone — they are genuinely different mechanisms, not the same trick renamed. • A back arrow on every reference panel. • Choosing a module now takes you straight to the control you chose.

New in this version: • Jazz vocabulary — modes, melodic minor, and lydian dominant, each shown with its chord symbol • ii–V–I patterns in all 12 keys • A free beginner exercise: every note in your range, tongued and stepped down from 16 reps to 1 • Drone mode for intonation work • A real swing feel — even eighths, with the weight where a player actually puts it • Concert pitch, adjustable 432–450 Hz • Two new instruments: E-flat tenor horn, B-flat treble-clef euphonium • Guitar and bass: a fretboard view showing exactly where the notes are, in the position a teacher would actually start you in

New: The Full Studio - a one-time unlock ($24.99, no subscription) for intervals, arpeggios, pentatonics, maqam scales, overtones, and extended range. New instruments: D trumpet, Eb trumpet, piccolo trumpet, Bb flugelhorn. New note values: half and whole notes are now available as a practice option (in addition to quarters, eighths, triplets, and 16ths), and appear automatically in the Overtones exercise. Fixed: notation now centers correctly on the staff. The core app - all 12 major scales, every instrument and transposition, the straight chromatic scale - stays free, always.
