Jam vs MyPianist
This page describes the difference. It doesn’t declare a winner: everything below about MyPianist was read off its own pages on October 10, 2026, not tested at a piano. We make Jam, so read our column accordingly — its gaps are listed at the bottom.
They’re different kinds of tool. MyPianist is closest to live-listening accompaniment: Software that listens while you play and responds in real time: it works out where you are and what you are playing, then plays with you. Jam is live-listening accompaniment for a MIDI piano.
| MyPianist | Jam (ours) | |
|---|---|---|
| Listens while you play | Yes. | Yes, over MIDI or through the microphone. |
| What you prepare first | Yes. You choose a piece from its library. | No. No chart, no song, no chord zone. |
| Follows your tempo | Yes, through the chosen score. | Yes, by default. It can also hold steady once it joins, or set the tempo and count you in. |
| What it hears | Your instrument, playing a known piece (accompaniment is piano) | Digital piano over MIDI, or any piano (acoustic too) through the microphone |
| Platforms | iPhone, iPad | Chrome or Edge on a computer. Microphone mode should also work in Safari, but we have not tested it there |
| Pricing | Free download; PRO subscription listed at $4.99 and $29.99/year on the App Store. | The demo is free. Playing your own piano is included with any HiveJournal subscription. |
Where MyPianist is ahead
Real tempo-following with expressive timing, engraved scores and practice tools. It does a different job: accompanying a written piece, not an improvisation.
What Jam doesn’t do
- New and experimental. We have measured it on a scripted demo, not yet with many real players.
- Synthesized drums and bass, not recorded or sampled instruments. Every hardware arranger and DAW above sounds better.
- Eight styles (four of them hip hop). Arrangers and backing-track apps have hundreds or thousands.
- 4/4 time only.
- Microphone mode is newer than MIDI: tested on synthesized recordings, not yet in a real room. With headphones it hears you cleanly; on speakers it also hears itself, so it holds tempo more than it follows you and is less sure of your chords.
- MIDI needs Chrome or Edge on a computer (Safari and iPad cannot read MIDI). Microphone mode is untested in Safari.
- No recording, notation or editing. It plays with you; it does not make a track.
