OctaMED is a music tracker for the Amiga, written by Teijo Kinnunen. The first version, 1.12, was released in 1989 under the name MED, which stands for Music EDitor. In April 1990, version 2.00 was released with MIDI support as the main improvement. In 1991 the first version with the name OctaMED was released, so-called as it could replay eight independent channels on the Amiga's four-channel sound chip. This was also the first commercial version of the software. The publisher had previously been RBF Software of Southampton, UK which was run by Ray Burt-Frost. The current publisher is A-EON Technology Ltd.
The distinguishing feature of MED and OctaMED in comparison to other music trackers on the Amiga was that MED and OctaMED had native MIDI support for external instruments via the Amiga's serial port – this allowed many musicians to sequence a combination of outboard studio equipment and internally generated sounds to create studio quality releases such as I Created Disco by Calvin Harris.
OctaMED was chiefly used by musicians to create stand-alone works, rather than by game or demo musicians to make tunes that play in the context of a computer game or demo.
Firstly, this is because the MED and OctaMED music replay routine is simply too slow to be used in a game or demo. Most trackers are optimized for speed of replay code, taking less than 3% of CPU time. MED took roughly 40% of CPU time. Secondly, and this is also one of the reasons why MED draws more CPU power, the MED format allowed a greater degree of complexity in music construction, with arbitrary length of pattern sheets, sections and blocks rather than a simple pattern-list, and a greater number of effects for the sound. This additional complexity was welcomed by music composers, who preferred more sophisticated structure to their compositions and did not see it as a simple list of timed note-presses.
The technique of playing more channels of music than the Amiga hardware was capable of was first introduced with Jochen Hippel's "Hippel 7V" routine, which used code initially developed for the Atari ST to perform software mixing of 4 channels to a single output, played back alongside the remaining three Amiga hardware sound channels. The seven-channel routine then appeared in a tracker called TFMX. Finally, the routine was optimized so it could mix an additional channel, resulting in eight channels of sound. This playback method was suited for instances where a number of samples that don't require fidelity can be played through the software mixed channel, and cleaner samples through the remaining three hardware channels.
OctaMED took a different approach, where two software-mixed channels are played through each of the four hardware audio channels. This brings some limitations, such as paired software channels sharing some effects such as hardware volume control, the higher-quality playback routine requires a more powerful CPU, and some louder samples can sound distorted due to limitations in the mixing process.
OctaMED was developed by Teijo Kinnunen on the Amiga until 1996. His last version, called OctaMED Soundstudio, had features like MIDI file support, ARexx support, support for 16-bit and stereo samples, hard disk recording, and support for up to 64 channels.
Teijo Kinnunen handed over the development of OctaMED to other programmers soon after the final Amiga version was released. The new programmers later released a Windows port, but the lack of features and presence of noticeable bugs meant this edition did not achieve the same level of fame as the Amiga release. More versions of the Windows port were later released. It was subsequently renamed to MED Soundstudio, and has had several releases under that name.
A later approach to extend the features of the Amiga version of OctaMED was performed by Kjetil Matheussen starting in 1997. By hacking the binary he managed to make a more low-level plugin system than was already available via the ARexx language. With the help of NSM (an open source patching and plug-in system for OctaMED[1]) the users could now get access to the CAMD MIDI library, 48-channel MIDI interfaces, signal processing plugins for the sample editor, interaction with the sequencer Bars&Pipes, and many other esoteric features, far extending the features offered for the commercial Windows version of OctaMED.
In February 2015 A-EON Technology Ltd acquired the rights to OctaMED for Amiga and Amiga-like next generation systems from RBF Software.[2]
In January 2024 active development of the Amiga source code was resumed by AmigaKit Ltd on behalf of A-EON Technology. OctaMED was updated primarily for inclusion in AmigaKit's forthcoming A600GS computer system. The upcoming OctaMED v8 will add important features such as AHI driver support and CAMD Midi Library support. Further GUI enhancements are planned.[3]
The official OctaMED Amiga forum was opened for users in May 2024 in advance of the new OctaMED 8 release.[4]
Current version is available for Windows and AmigaOS platforms, called MED SoundStudio.
