Roland MT-90S Music Tutor

This page is devoted to the wonderful Roland MT-90S Music Tutor sound module.

From the Roland website:

Increasing the widespread use of interactive music files, the MT-90S Music Player is a Standard MIDI File-based Music Tutor which features a new compact design and backlit LCD. Its easy operation and unbelievably low price makes it easy for all music learners, educators and performers to learn, teach and play with interactive music disks.

  • Compact, affordable music player with built-in speaker and GM2/GS-compatible sound source
  • Plays back Standard MIDI File (SMF) disks via internal floppy drive
  • Front-panel icons for simple operation; portable, lightweight design
  • Backlit LCD displays song title, tempo and lyrics of compatible SMF disks
  • Microphone input with echo effect for vocal lessons/karaoke performance
  • Intro Countdown gives singers a countdown before song melody begins

Plays Back Standard MIDI Files

Using the internal 3.5-inch disk drive, the MT-90S can load commercially available Standard MIDI File disks and play them back through the internal speaker. Song data can then be played back at any tempo including part mute capability. A high-quality GM2/GS sound engine provides realistic instrument sounds that make practice and performance fun.

Portable And Easy To Use

The MT-90S features icon-based buttons and a user-friendly 16×2 character backlit LCD, making common operations such as playing songs, muting parts, or changing tempo and musical key as easy as using a metronome. Lightweight design and a built-in grip handle make it possible to practice virtually anywhere.

SMF Lyric Display

When used with compatible disks, the new backlit LCD can display SMF song lyrics in real time. And by connecting a microphone, you can transform the MT-90S into an instant karaoke machine complete with a built-in echo effect.

Downloads

Below are the original MT-90S documents that came in the box with it. Also below is the original 3.5″ floppy disk packaged with the MT-90S. It contains MIDI files playable immediately on your MT-90S and is a direct replacement for a lost floppy disk that shipped with the unit.

What’s Inside?

Here are some pictures of the inside of a Roland MT-90S. Of particular note are the ratings of the speaker and the disk drive info. The owner’s manual listed the speaker as a 10w speaker, but this one has a 15w. I think it’s a late production run since the original shipping label shows it shipped to its original owner in California.
