Song Sketchpad — Compose Guitar Riffs, Tab & Drum Beats Online

The Composer is a multi-track sketchpad that meets you at either end of the skill curve: paint notes onto a grid that is quantized to your chosen key so nothing can sound wrong, or type straight into real tab notation — 5h7 hammer-ons, 7b9 bends, palm-mute marks — and hear it played back with a recorded drum kit underneath. Add a second guitar, a bass or a ukulele lane, mix time signatures bar by bar (yes, 7/8), and balance sections with per-section faders.

Four built-in songs — from a pop groove to full metal — show what the engine can do and give you something to dissect. Your sketches autosave on your device and share as links that reopen the exact arrangement. The Composer is part of ThunderFret Pro — it couples with the Jam band, which turns anything you sketch into a live backing track to solo over, and it exports multi-channel MIDI to your DAW.
