MIDI software patch editors, librarians, sequencers and more

By Jim Pierson-Perry

With its built-in MIDI ports and low cost, the ST is widely regarded as the new "musicians' computer." ST MIDI programs range from a player-piano simulation (based on real piano rolls) to a professional 64-track sequencer system. Atari Corp. is helping to spearhead this MIDI invasion by encouraging music stores to sell ST computers.

To use most of this flood of MIDI software, you need only your ST and a MIDI-equipped synthesizer, such as the Yamaha DX-7 or the Casio CZ-101. Of course, the more MIDI equipment you have (samplers, drum boxes and expanders, for example) the more involved your music can be--and the more you'll appreciate having the ST to hold it all together!

Here we'll cover five types of MIDI software: music players, sequencers, scoring programs, librarians, and patch/sample editors. Each category has programs with various levels of features, and there is some overlap between them. Unless stated otherwise, you can run all of these programs on any ST.


A player program uses a data file to reproduce music on a MIDI instrument (typically a synthesizer)--sort of a digital jukebox. Some player programs let you enter musical data in step-time along with non-music control events, such as changing the synthesizer voice or the tempo. These programs also may offer song playback through the ST's internal monitor speaker as well as external MIDI instruments. For a player program, availability of prerecorded music on ST disks or as BBS files is important, unless you only want to hear your own playing.

A sequencer records real-time or step-time input of MIDI music and controller data. Some versions allow sophisticated editing and music manipulation functions. Sequencers are like multi-track tape recorders and many such programs use a tape recorder-style user interface. The more powerful sequencers allow editing and chaining of individual music passages (sequences) to build a song.

A good sequencer program lets you edit music data much the same as you would edit text with a word processor--you insert or delete passages, and cut and paste repeated sections. You also need external syncing if the song is to be tied to a drum machine or tape deck. Other useful features are note timing correction, a metronome to keep steady time while playing, punch-in and punch-out to overdub and correct bad notes, and the ability to address system-exclusive functions of your MIDI equipment.

Ideally, a scoring program takes a music data file and converts it into printed sheet music. In practice, automating this transcription process is very difficult because of music's many rules and exceptions. Options to consider include the scoring style (solo voice up to full orchestra with drum parts); addition of Iyrics, chord, musical or even user-definable symbols; notation editing; and what printers are supported. Scoring programs generally are only valid with sequencer programs from the same company due to variations in file formats.

Library management programs are caretakers of such MIDI data files as synthesizer patches, drum machine patterns, and controller effects. Librarians can build composite files of system exclusive data for all instruments in your setup. At the touch of a button, a file can load all parameters for a particular song. A good librarian is indispensable for MIDI-based systems in live performance.

Equipment meeting the MIDI 1.0 specification usually can be accessed by a generic librarian, rather than requiring a separate program for each instrument. Two exceptions are the Casio synthesizer line and Roland drum machines, which use nonstandard system exclusive data transfer specifications and need specialized software.

Synthesizers are no longer the expensive toys of rich rock stars. Like most electronic equipment, their price have dropped while their useful features have skyrocketed, and now, they're an integral part of "serious" music composition and performance. Many people have added digital keyboards to their work--everyone from the members of the local bar band to Hollywood film composers.

Today you can choose from among a number of reasonably-priced electronic keyboards offering everything from velocity sensitivity to sampling capability--and of course, MIDI. Below is a sampling of some hot boxes with not-so-hot prices.


The Casio CZ-1 ($1,399) is a full-featured, 61-key touch- (velocity) sensitive synthesizer. It comes with 64 loaded patches (sounds) in RAM, and can hold an additional 64 patches which you create. You can add optional ROM cartridges for additional sounds, and call up your patch information on the CZ's LCD screen. Casio, P.O. Box, Dover NJ 07801. (201) 361-5400

The Casio CZ-5000 ($1,199) which is one step down from the CZ-1, contains 61 velocity-sensitive keys, 32 presets and 32 memory voices. Optional ROM cartridges hold additional sound information. View your patch programming on its built-in LCD screen.

The Casio CZ-3000 ($999.00) contains all of the features in the CZ-1000, but includes 61 keys, 32 presets and 32 in-memory voices.

The Casio CZ-1000 ($699.50) features 49 keys, 16 presets, and handles 16 internal voices. MIDI capable and MIDI ready. One of the most popular Casio synthesizers, this one may be the best buy for your ST.
