Jampea

Jampea is a free online MIDI music editor that works directly in your browser. It was created by the same developer as the famous Photopea (the photo editor that imitates Photoshop), and follows the same philosophy: offering a powerful, professional, and accessible tool without the need to install heavy programs.

Here's a detailed description of what it offers:

What does it do?

Unlike common audio editors (like Audacity), Jampea is a music sequence (MIDI) editor. This means that instead of manipulating recorded sound waves, you manipulate musical "instructions"—notes, instruments, and beats—that the computer plays in real time.

Key Features

Familiar Interface: If you've used Photopea or Photoshop, you'll feel right at home. It uses the concept of layers, but instead of images, each layer represents a different musical instrument.

Piano Roll: Features a grid where you draw musical notes with your mouse, adjusting the pitch and duration.

File Support: Allows you to open and edit files in .mid (MIDI), .gp (Guitar Pro), Musescore, and MusicXML formats.

Various Instruments: Includes a vast library of sounds, from pianos and guitars to full percussion. You can also upload your own SoundFonts.

Completely Online: No account or download required. All processing happens in your browser.

Who is it for?

It's ideal for composers, music students, or enthusiasts who need to create quick arrangements, practice sheet music, or export files to other music production software (DAWs).
