    Chuso's Free Soundfont Collection

    Chuso's Free Soundfont Collection

    A free high quality soundfont collection for live setups

    Within the age of huge -and expensive- sample libraries that fullfill the dreams of every virtual composer, it seems that Soundfonts aren't needed anymore. However, some musicians still need the simplicity of these old fellows in live shows. Chuso's Free Soundfont Collection (ChusoCol) is a simple collection of instruments that would help every live musician to establish their own setup. It is the collection I particularly use and update, and the samples come from a variety of open resources, such as Sonatina Symphonic Orchestra (http://sso.mattiaswestlund.net/), Salamander Grand Piano (http://freepats.zenvoid.org/Piano/) or the GeneralUser GS (http://www.schristiancollins.com/generaluser.php), as well as some samples by myself. It is intended for live musicians who want the better sound with low requirements, in a library of ~300Mb. The library is still in alpha state, and improvements are being made. The final soundfont is compiled using Polyphone (http://www.polyphone.fr/)

    Kangas Sound Editor

    Kangas Sound Editor

    Synthesizer, mixing, sound effects, music composition and production.

    This kangaroo-themed program allows the user to create their own music and sound effects, effectively from scratch. There are two variants of the program: Kangas Sound Editor which requires MySQL for its database, and Kangas Sound Editor QI which does not (it uses an internal database - HSQLDB - instead). Kangas Sound Editor (QI) uses a system of boxes or cells, which are placed by the user onto a timeline using drag-and-drop, and which represent entities such as chords, repetition, and individual sounds or notes. The program's database allows the user to create and store harmonics, used for constructing melodic instruments, and anti-harmonics, which are used for constructing percussion instruments. Users can collaborate with and build on the work of others via an XML import/export facility.

    Timewave Synthesizer

    A binary waveform synthesizer based on Timewave Zero

    A binary waveform synthesizer derived from and based upon Timewave Zero theory by Terence McKenna. His theory proposes that the structure of time is a complex wave with a scalar potential, and the King Wen sequence of the I Ching is the 64 hexagram code from which the waveform of time is derived; that the King Wen sequence maps the linear progression of the human states of mind, which ultimately substantiates this waveform. This theory is the basis for the well-known novelty computer program he and others had developed. This program synth was made in supercollider.
