4OP Librarian is an application for the Macintosh which allows you to make up
library of voice data for 4-Operator Systhesizer by YAMAHA.

One window has one voice data, and you can open windows as many as you want. (It's only limited by partition size of the application.)

When this application receives bulk dump MIDI data, new window will open and
show you the parameter. You can keep 32 patches in one file, so it's easy to
replace 4-Operator Systhesizer's internal patches.

Supported Synth :
- DX100, DX21, DX27, DX27S, TX81Z, WT11, TQ5, YS100, YS200, B200, DX11 or V50
(I have NOT checked for all of the synth, though.)

Features :
- Fat Binary.
- Apple Script recordable.
- Macintosh Drag and Drop support.
- Inline input support for Japanese text.
- Navigation Services support. (PowerPC Only)

This application requires :
- Macintosh with 68020 or higher / PowerPC
- System7 + QuickTime or System7.1 or later
- Apple MIDI Manager or OMS (Open Music System)
