= New file/data types and terminology = 

== Sound library ==

=== Extension ===
{{{.h2l}}} or {{{.h2lib}}}

=== Description ===
Replacement for the current Drum KIt (.h2drumkit).

=== Grounds ===
  * .h2l is shorter than .h2drumkit which is way too long
  * Hydrogen will no more exist as just a beatbox, it's gonna become a music production tool, so "sound library" is much more appropriate

== Instrument ==

=== Extension ===
{{{.h2i}}} or {{{.h2inst}}}

=== Description ===
Data for a single instrument, including sample(s) and Synthesizer setup

=== Grounds ===
  * Will be useful when each instrument will be a great synth on it's own, e.g. to share a synth or bass patch

== Composition ==

=== Extension ===
{{{.h2c}}} or {{{.h2comp}}}

=== Description ===
Replacement for the current Song (.h2song)

=== Grounds ===
  * .h2c is shorter than .h2song
  * "Song" is not a good word for something you do not have any voice/singing in

== Sequence ==

=== Extension ===
{{{.h2s}}} or {{{.h2seq}}}

=== Description ===
A pattern for a single instrument/track

=== Grounds ===
  * Will be useful for sharing stuff like basslines, riffs etc.

== Project ==

=== Extension ===
{{{.h2p}}} or {{{.h2prj}}}

=== Description ===
The whole Hydrogen setup: Composition, Samples, Instruments,etc. This is thoroughly described on the [wiki:development:Project Project definition/specification] page.
