Full name | Module Music Formats (Mods) |
Description | A group of digital music file types produced by a variety of software applications called trackers. Mod files include sequencing information (similar to MIDI_SD) and waveform samples (generally PCM audio), and may be compared to XMF files. Information about a variety of mod formats is linked from http://pipin.tmd.ns.ac.yu/extra/fileformat/modules/index.htm; several mod file types are enumerated in File type signifiers, below. |
Production phase | May be used by composers or arrangers for initial-state activities, in middle-state exchange of data or archiving, or for final-state, end-user delivery. |
LC experience or existing holdings | None |
LC preference | None established at this time. XMF is likely to be preferred to mods. |
Disclosure | Little or not documentation. |
Documentation | None identified at this time. |
Adoption | Various types of mods are encountered on the web. One commentator writes, "Mods are extremely popular in the demo world and offer a way of making music of an acceptable level of quality rather cheaply." |
Licensing and patent claims | None investigated by the compilers of this document. |
Transparency | Unknown; may be relatively transparent. |
Self-documentation | Unknown. |
External dependencies | See MIDI_SD and DLS. |
Technical protection considerations | None known to the compilers of this document. |
Normal rendering for sound | Good support |
Fidelity (support for high audio resolution) | Not applicable; fidelity depends upon the performance of external hardware and software. |
Support for multiple sound channels | [Same as MIDI_SD ?] |
Support for downloadable or user-defined sounds, samples, and patches | Yes |
Functionality beyond normal rendering for sound | Not investigated at this time |
