OctaMED offered an Amiga musician more parts without adding more audio hardware. Paula still had four sample-playback channels. To play eight sampled voices, the program had to combine sounds in software before sending them to the chip.
The program grew from MED, Teijo Kinnunen’s music editor. Contemporary features in CU Amiga and Amiga Computing describe the progression towards OctaMED 2, rather than treating every MED and OctaMED release as one fixed product.
Patterns and a stave
Like Soundtracker, MED arranged notes in patterns that could be placed in a song sequence. A musician could reuse a pattern instead of entering the same phrase again for each verse or repeated passage.
OctaMED 2 also offered a score editor. Jason Holborn’s December 1991 review describes entering notes on a stave, an alternative to the tracker’s columns of note names and numbers. Those are two views onto a composition, useful to people arriving with different musical habits.
MIDI facilities supplied another route: a pattern could control an external instrument rather than use an Amiga sample. The number of MIDI parts should therefore not be read as a count of extra Paula channels. (Amiga Computing 43, review and contemporary OctaMED 2 advertisement.)
Mixing has a cost
The original OctaMEDPlayer guide makes the trade-off explicit. Its mixing options affect sound quality and the amount of processor work. The editor’s visible channels describe musical organisation; the playback system still has to deliver audio quickly enough.
That matters when music shares the Amiga with a game or animation. More simultaneous notes can leave less time for other work. An edition’s channel count alone does not describe how suitable its player is for a particular production.
A song and its player
The separately distributed player could load MED and OctaMED material without providing the full composition environment. Its documentation credits Kinnunen and identifies RBF Software in the later commercial distribution.
The distinction between composing and replaying connects OctaMED with tracker music more broadly. A song needs both its musical data and a player that understands the commands and sound facilities used by that edition.
