Synthesizers with transposition

 

— the ability to shift each note of the synthesizer by a certain number of semitones down or up. For example, when the sound is shifted two semitones (a whole tone) up, the note “la” will sound on the “sol” key, the note “si” will sound on the “la” key, etc.; and the melody, originally written in the key of "A minor", when performed on the same keys, will sound in "B minor".

Thus, transposition allows you to translate the synthesizer part into a different key without having to relearn the melody — it can be played on the same keys. Anyway, this is convenient, and this function is especially useful in cases where there is no time to relearn the part (for example, if a musician has to perform with a new vocalist who does not “pull out” individual high notes).
