## What is SUS4 Sketchpad?

Record the idea while you still have it, and keep the lyrics, chords and takes in one place.
Sketchpad works out the key and tempo of what you sang or played.
Fully on-device: no cloud, no account.

Each sketch has a title, key, tempo, time signature, tags, lyrics, a chord list and voice notes. Pick chords from a picker (root plus quality, sus4 included) and they sit under the lyric.

• Sketches with key, tempo and time signature detected
• Lyrics, chords and voice notes together
• A chord picker with sus, add9, dim and aug
• Tags across your notebook
• Everything stored privately on your phone

For songwriters who lose ideas in the voice memos app, and bands collecting riffs between rehearsals.

Pro, or SUS4 All-Access across the whole range, adds hum-to-MIDI melody capture, chord suggestions, the lyric assistant and MIDI export.

Made in the UK by working musicians.
