Music Suite

Music Pitch & Speed Changer

Pitch & Speed changes the key and the tempo of any song, separately. Slow down a fast solo without changing its pitch, transpose a song to suit your voice or instrument, and loop the bar you are learning until it sits under your fingers.

Built for musicians who practise with recordings: singers, guitarists, bassists, pianists, drummers, students and teachers.

Change the pitch

Transpose up or down by up to 24 semitones, in steps of one semitone
Fine-tune in cents (±50) to match a detuned recording or an instrument that is not at A440
The tempo stays the same while the key changes
Natural voice: keeps voices sounding natural when you shift the pitch

Change the speed

From 25% to 400% of the original speed
The pitch stays the same while you slow down or speed up
Link pitch and speed: works like a record player, faster sounds higher

Loop any section

Set an A-B loop and repeat a riff, a chorus or a tricky passage
Drag the A and B markers on the waveform to adjust the loop
Tap or drag the waveform to jump anywhere in the song
Skip back or forward 5 seconds

Key and tempo detection

Detects the key and the BPM of the song
Shows the new key and tempo after your changes, so you always know what you are playing in

Effects

10-band equaliser (±12 dB) with Flat, Bass, Voice and Bright presets
Preamp and left/right balance
