About
Tap a note and the choir has its starting pitch.
Every note from C3 to B5 with an adjustable A4, so the group starts in the right key.
Fully on-device: no cloud, no account.
Pick the octave, tap the note, and it plays a clean tone. It needs no microphone, so it works in a church, a rehearsal room or the car on the way to a gig.
• 12 notes per octave, octaves 3 to 5
• A4 reference you can move away from 440 Hz
• Works offline, with no mic permission
For choir leaders, a cappella and barbershop groups, brass bands and singing teachers.
Pitch Pipe+, part of Pro and SUS4 All-Access, adds a drone that holds the note, chord drones (major, minor, sus2 and sus4), intervals, glide and five tones from sine to plucked.
Made in the UK by working musicians.
