Galaxy is Opcode's universal librarian. It was one of the first packages
available, and is probably one of the most robust. It offers seamless
integration with
OMS
and
Vision, although as a compulsive
Max user I don't make much use of the latter. It supports parent-child linkage for
cut and paste, even for Gearhead/Korg Wavestation wave sequences
(although the other packages have probably caught up
by now).

The librarian package comes free with Vision; the editor is extra.
Editor usability varies from module to module, of course, although generally
the editors seem clean and clear. I make heavy use of the
Gearhead/E-mu Morpheus
editor, and find it quite stable, although I've come across a bug or two.

In general, editor writers are at the mercy of the implementors of the
instruments' firmware. Some instruments are so
totally f*cked
that a decent computer editor is impossible. Some instruments have a
good multitimbral specification with multiple edit buffers; others
don't. Then again, some of the Galaxy editor modules blatantly
ignore the multitimbral
capabilities of their instruments, which is extremely irritating when
sequencing. I guess the advice is: try before you buy, for any
particular editor you're interested in.
