If you see English words sometimes, this update should fix the problem.

- Extended upper range of guitar to classic nylon string limit B5 (sound) or B6 (written) - Localised screenshots for a number of regions

- We are shipping this major update v3.3 with a lot of new and cool features. - Another notation upgrade to our sheetmusic render engine : ability to change clef to reduce excessive use of ledger lines. 1. The very first application is all the scale and arpeggio exercises in Music Theory section. - transition between bass and treble clef for grand stave instruments (piano and harp). - transition between alto and treble clef for viola. - transition between bass and tenor clef for cello, bassoon and trombone. 2. Also included clef change in a number of songs. - Grand stave (both hands) is now available for chromatic scale exercise for piano and harp. - Introduction of 'intonation accuracy' for microtonal instruments : violin, viola, cello, double bass, trombone. We understand that beginners often cannot play perfectly in tune. You will not be punished because your intonation is not perfect. Instead, the app will show you a yellow tick. - Green tick : Perfect intonation - Yellow tick : Acceptable hit but slightly out of tune The achievement dashboard will also show you your overall intonation accuracy. - We have added Book 13 with a number of Grade 1 and Grade 2 songs to help user build a solid foundation. 1. Jingle Bells 2. We Wish You a Merry Christmas 3. Liszt Liebestrume (easy version) 4. Scarborough Fair 5. Oh! Susann 6. Bach Petzold Minuet in G Minor

- We have significantly improved our polyphonic detection engine and harmonic cancellation algorithm. Detection in songs (both hand) and chords is now faster and more accurate. - Added 'Happy Birthday' to Grade 1 and Book 12. - Fixed a UI bug.

- Stretched the upper range limit for a number of instruments so that 3 octaves can be used in scale and chord exercises. - Further improvement on rhythm detection. - Better A0 and B0 detection in chromatic tuner.

- Improved polyphonic detection engine and latency correction algorithm. - We applied our up-to-date low pitch detection algorithm to all tuners. Following tuners have become much more efficient: Full Range (low), Cello, Double Bass, Guitar, Bass, Saxophone (Tenor and Baritone), Trombone, Tuba - 3 octaves are now available for all scale and chord exercises (if note range is allowed for selected instrument), which benefit students who are preparing for Grade 4 exam or above. - Accidentals and half-step smart spelling have been applied to labels on fingerboard, fretboard and pitch meter. - We have also optimised detection for extremely high pitch, especially for violin and piccolo.

- We applied our up-to-date low pitch detection algorithm to all tuners. Following tuners have become much more efficient: Full Range (low), Cello, Double Bass, Guitar, Bass, Saxophone (Tenor and Baritone), Trombone, Tuba - 3 octaves are now available for all scale and chord exercises, which benefit students who are preparing for Grade 4 exam or above. - Accidentals and half-step smart spelling have been applied to labels on fingerboard, fretboard and pitch meter. - We have also optimised detection for extremely high pitch, especially for violin and piccolo.

- Intonation accuracy requirement is now adjustable by users. Low: minimum accuracy acceptance while still ruling out complete out of tune. Medium: higher accuracy acceptance for day-to-day intonation practice. High : performance level accuracy is required to pass the note detection. - Intonation hint is now also available for trombone. - Improved low pitch detection further. - Fixed spelling of accidentals for many scale and chord exercises. (We are also planning to enable smart spelling for note labels on pitch meter and fingerboard hint in future version)

- New feature 'intonation' hint is added in this relese. For microtonal instrument learners such as violin, viola, cello or double bass, pitch accuracy is indispensable. You can now slowly develop this skill through our new intonation hint function. A pitch meter will help you identify whether you are playing slightly lower or higher than the expected note. We so far made the requirement of pitch accuracy slightly higher in this mode so students can focus on their accuracy check. In future version, we will make it adjustable by users. We will support this feature for trombone in next version. Stay tuned. - We have generally improved note detection speed so the rhythm timing can be slightly tightened to give you better rhythm accuracy check, especially for low pitch instruments. - New composer added: (Our very first ragtime composer) Scott Joplin - New songs added to Book 12: 1.

Theme from Hungarian Rhapsody No.6 by Liszt 7. Consolation No.3 by Liszt

Fixed bug and stabilised the 'Melodic Randomness' algorithm.

- We are proud to introduce a new feature called 'Melodic Randomness', which allows users to control how notes are generated in Full Flow Sheet Music mode using advanced machine learning algorithm. Lower coefficient gives the practice more natural feeling and sounds a lot more like real music. This feature also helps users build stronger common pattern recognition skill. On the other hand, higher coefficient helps users develop fast speed of random note recognition and reaction. - We have also made great improvement on note detection. Detection speed for low pitch instruments has been significantly improved by supplementing FFT with YIN algorithm. - Instruments that benefit from boost of note detection efficiency: 1. Cello 2. Double Bass 3. Bass Guitar 4. Bassoon 5. Trombone 6. Tuba
