Sound Designer, and Pro Tools. These pro<strong>gr</strong>ams allow the user to manipulate sound file samples, but they<br />

do not use MIDI techniques to edit the sound file.<br />

Music Patch Editors work directly with the sound patches within a synthesizer. Patch editors are<br />

designed specifically for individual synthesizers because each company uses their own system exclusive<br />

information to create their pro<strong>gr</strong>ams. First the hexadecimal code F0 is used to identify the status byte of<br />

system exclusive. The status byte is followed by a data byte that identifies the manufacturer. All data bytes<br />

that follow pertain to MIDI information created by that particular manufacturer. At the end of the system<br />

exclusive message will be the hexadecimal code F7 end of exclusive command.<br />

Patch Editors allow the user to change the size of envelopes, types of filters, samples, waveforms, panning<br />

information, modulation effects and basically anything that changes the parameters of the patch. Each<br />

manufacturer uses different techniques to create sounds for the synthesizer so each Patch Editor must be<br />

designed for the specific synthesizer. Universal Patch Editors are pro<strong>gr</strong>ams that support many different<br />

MIDI devices. That way a user may by one pro<strong>gr</strong>am that will support their studio that has products from<br />

Roland, Yamaha, Korg or other manufactures.<br />

The example on the left is the Universal<br />

Patch Editor Galaxy. Here the user is able to<br />

make changes to the envelopes, original<br />

oscillators, filters and other effects.<br />

Patch Librarian software allows the user to organize their sounds, but<br />

they may not edit the sounds. Librarians are a <strong>gr</strong>eat way to create a bank<br />

of sounds for a specific composition or creating your top 64 or 128<br />

sounds.<br />

Sometimes a sound<br />

from one synthesizer<br />

may be layered with<br />

MIDI to another sound<br />

in a different<br />

synthesizer to create a<br />

new combined sound.<br />

The librarian will<br />

allow the user to move<br />

patches so the<br />

combination is on the<br />

same number.<br />
