Main Features
- Live tab detection — play a phrase and the holes appear on screen as you go. No typing, no notation software.
- Full harmonica notation — blow and draw holes, bends, and overblows/overdraws, all marked clearly and colour-coded.
- Works with all 10 hole, Richter-tuned diatonic harmonica (all 12 keys)
- Playback with tempo & loop — hear your sequence back as piano notes, slow it down to study a lick, or loop it to drill it.
- Scale degrees (the Number System) — see the musical numbers (1, ♭3, 5, ♭7…) in green below your tabs, so you understand why a lick works — not just where to play it. Includes a built-in plain-English primer.
- Position transposing — see the same lick in 1st, 2nd, 3rd, 4th, 5th, or 12th position, and exactly which harp and holes you’d use to play it there.
- Live piano keyboard — a visual, playable reference that shows how the harmonica maps to standard notes; great for working tunes out and for teaching.
- All 12 keys, pre-calibrated — tuned for how harmonicas actually behave (including bends), with optional custom calibration you can save, export, and import.
- Save & print — export to RTF for Word, Pages, or Google Docs. Mark them up and print for the stage or your students.
What They Say…
“I’ve only recently discovered Roly and his fantastic playing. I needed a harp session in a hurry here in the UK, and although half a world away, Roly did the most amazing e-session for me in superquick time, recorded a superb performance, and I now have his number on speed-dial ! He was extremely easy to communicate with, and very easy to work with regarding arrangement directions. I can’t recommend him highly enough and I know we’ll work together again soon.”

“I have worked with Roly Platt for over 30 years in many different musical situations. He is a first class musician and a first class human being. He’s worked for me on a wide variety of recordings (records, jingles, tv shows) and is always an inspiration and a positive influence on whatever project he’s involved with. He is, simply put, one of the best musicians I have ever worked with. He’s blessed with amazing technical skills but he also has great taste, feel and musical instincts that can… Read more
