The Clavia Nord Modular series was a line of synthesizers produced by
Clavia, a Swedish digital synthesizer manufacturer in 1997. They are
analogue modelling synthesizers, and had an innovative software that
allowed the user to graphically patch modules on their home PC/Mac in
the same manner as traditional hardware modular synthesizers of the
1960s-70s. These patches could then be sent to the hardware DSP over a
standard MIDI interface and stored/manipulated live.

There were three flavors of the original Nord Modular, a keyboard or
rack version with 4 DSP cores (expandable to 8), and a Micro Modular
with 1 DSP in a package approximately the size of a VHS tape. The
editor software ran on Windows and Mac OS8-OS9. A beta version of the
editor was also released for OSX but was dropped when Clavia
introduced the G2 modular engine in 2004.

I have included the version 3 editor software (as found on the Nord
website), hardware updaters (one for the Micro and one for the
multicore versions), and beta OSX editor.

According to Clavia: "This beta version of the editor is pretty much
fully functional with OS X 10.1.5 and up til 10.6.8. A known bug is
that if you control click on a module, to delete it or change its
name, the editor will promptly crash. The workaround is to select a
module and press the delete key, and to rename it just double click on
the name of the module."
