dx7-patches

JSON representation of a collection of Yamaha DX7 patches compiled by Glenn Scott

For the original readme: ftp://ftp.ucsd.edu/midi/patches/DX7/README.1ST

History

These files have been around for a while. They're currently hosted on a ucsd website. However, I retrieved them from Dave Benson's website. Ted Felix's dx7 utility then helped convert the sysex information into something I could read, which I then parsed with a file included in a different branch of this repository.

Organization

The original files came in banks of 32 patches each. Each top-level directory here represents one bank, containing the bank's 32 patches as json files.

Usage

npm install --save dx7-patches

var ePianoPatch = require('dx7-patches/rhodes1/epiano-1');
var FictionalDX7 = require('fictional-dx7');

var synth = new FictionalDX7();
synth.fictionalSetPathMethod(ePianoPatch);

midi.connect(synth); // fictional?

Walkthrough

There's a wealth of patches here. You can search the repo:

• 255 'piano' patches
• 36 'rhodes' patches
• 242 'bass' patches
• 34 'trumpet' patches

Format

I imagine the formatting, as well as the available patches, will change over time. Format changes will result in a version bump. But below is an example patch:
