Upgrading The E-mu Audity 20 Years After Factory Support Ended

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

Cheap Smart Ring Becomes MIDI Controller

It costs about $20, and is remarkably easy to hack. [Floyd Steinberg] took advantage of this to turn it <a href="https://www.youtube.com/watch?v=0aNxuAbEwvM" target="_blank">into a rather unique MIDI controller.</a></p>
<p>What makes the Colmi R02 somewhat unique is that the manufacturer did not try to lock out users from uploading their own firmware. You don’t even really need to “hack” it, since there is no code signing or encryption. You can just whip up your own firmware to make it do whatever you want.</p>
<p>To that end, [Floyd] set up the ring to act as a device for musical expression. When connected to a computer over Bluetooth, data from the ring’s accelerometer is converted into MIDI CC commands via a simple web app. The app allows the MIDI messages to be configured so they can control whatever parameter is desired. [Floyd] demonstrates the ring by using it to control filter cutoff frequencies on an outboard synthesizer, with great effect.</p>
<p>You could theoretically just strap an accelerometer to your hand with a microcontroller and achieve similar operation. Howe

Companion MIDI Pedal Helps Roland Groovebox Along

https://fed.brid.gy/r/https://hackaday.com/2026/01/30/companion-midi-pedal-helps-roland-groovebox-along/

<div><img alt="" class="attachment-large size-large wp-post-image" height="449" src="https://hackaday.com/wp-content/uploads/2026/01/Pedal_678115-e1768799554381.jpg?w=800" style="margin: 0 auto; margin-bottom: 15px;" width="800" /></div><p>The Roland SP-404 Mk2 is a popular groovebox that can deliver a great beat if you know how to use it. If you’re seeking greater control than is available out of the box, though, <a href="https://github.com/RomainDereu/Romagnetics_FS-404" target="_blank">you might like to try a custom pedal built by [Romain Dereu].</a></p>
<p>The concept is simple enough—[Romain] whipped up a bespoke MIDI device to specifically control various features of the SP-404. It’s based on an Arduino Nano, though it could also be built with an Arduino Uno if so desired. The microcontroller sends the requisite MIDI messages out via its serial UART. The microcontroller is built into a pedal-style enclosure with a big toggle switch and a foot switch. This enables the triggering of various pads on the SP-404, with modes selected via the toggle.</p>
<p>It’s a simple build that opens up new possibilities when playing with the SP-404. If you’ve ever wanted a custom device to <a href="https://hackaday.com/2018/09/04/make-the-surface-dial-do-more-things-such-as-midi/">spit out some specific MIDI commands</a> to control the synths or drum machines in your performance rig, this project is a great example of how easy this is to achieve. Meanwhile, if you&
