This guide covers how to check your Alesis HD's OS, as well as the proper procedure for updating using MIDI or Ethernet.
To obtain the latest OS for your HD24, visit the product page and select the Docs and Downloads tab.
There are two reset operations that will solve any virtually any non-hardware related issue. Try these before considering reloading the firmware or having the unit serviced.
Having the latest OS is important, especially when information is being swapped between multiple HD24 units, or to ensure compatibility with Alesis Fireport. Hard drives containing songs and projects recorded on an HD24 using and older OS will not be recognized by the Alesis Fireport or the FST connect software that comes with it. The current OS uses a slightly different files system than older OS versions. If a drive containing Songs and Projects recorded on an HD24 using an older OS is inserted into an HD24 with the latest OS, the HD24 will offer to update the drive's file system. The file system update will allow compatibility with the new OS. While no data will be lost, once the drive is updated, it will work if returned to an HD24 with an older OS.
The Operating System can be updated either via MIDI or Ethernet. Alesis strongly recommends updating via Ethernet.
Updating via MIDI requires a computer with a MIDI interface, and software capable of transmitting MIDI SysEx files. It's important to note that if the update via MIDI fails to complete, the HD24 will be unusable until a successful update via MIDI can be completed.
This risk is not present when updating via Ethernet. For this reason, updating via Ethernet is preferred. If the update fails, the process will be safely aborted, with no ill affects to the HD24 and you can simply try again.
You will need to download and install a SysEx program to send the OS to your machine.
First reinitialize the HD24 by powering up while holding down the Play and Record buttons. Then the latest HD24 1.21 update can be downloaded at www.alesis.com/hd24 .
When connecting your HD24 to your Windows PC's Ethernet port, you need to use a crossover cable. This looks the same as a regular Ethernet cable, but has a different internal wiring. A crossover cable will often have 'crossover' printed repeatedly along the length of the cable's vinyl jacket. This is not a typical cable for most people to own, and is usually purchased for a specific application or purpose. You can easily find these specialized cables at online retailers such as amazon.com by searching ethernet crossover cable.
Note: connecting to a Macintosh uses a normal Ethernet cable. Also, avoid using a hub as this may make it harder to connect. Here is a update procedure for Windows:
IMPORTANT: only attempt to update via ethernet by connecting your HD24 directly to your computer's ethernet port. Do not attempt through a router or any intermediate device.
