It was fine, if a little limited, particularly where upgradability was concerned. E-mu would later offer firmware upgrades over MIDI with the 2.00 firmware, but to <em>get</em> the 2.00 firmware, you needed to ship the box back to E-mu. <a href="http://zine.r-massive.com/e-mu-audity-2000-os-upgrade-for-v1-00-units/" target="_blank">Or you did… until now.</a></p>
<p>Realizing that E-mu is long gone and they weren’t going to handle any further firmware upgrades, [Ray Bellis] set about finding another way to help aggrieved operators with gear stuck on v1.00. [Ray] had managed to lay hands on a Audity 2000 service manual as well as the official 2.00 upgrade kit in an estate sale, and set about reverse engineering it to help the community. It turned out that upgrading from 1.00 to 2.00 required the use of a special boot ROM and a flash device containing the upgraded firmware image. Booting from the special ROM required the use of a jumper, and when engaged, the ROM would copy the updated image to the device itself.</p>
<p>[Ray] didn’t want to duplicate the standard upgrade device, as that seemed a littl](https://files.mastodon.social/cache/media_attachments/files/116/035/202/935/939/565/original/4e133eab351aac6d.jpg)
