Miscellanea

Music

I just love music since an early age.

My double interest for electronics and music has lead quite unsurprisingly to spend some times on toys such as MIDI protocol and expanses, sequencers, synthesizers and stuff like that. You can find here some music pieces written or somehow adapted by myself. I wrote some articles here and there.

The sounds samples come from E-mu Proteus/1 and Proteus/2, a Yamaha P50-m, some virtual instruments from Apple, Arturia, Spitfire Audio and UVI, a Roland digital piano as well as a GEM S2 keyboard.

	My Bandcamp page (opened in 2024) I opened in 2024 a page on Bandcamp.
	My Soundcloud page (opened in 2020) I opened in 2020 a page on Soundcloud. I will publish there some new and old piece of music.
	New Star (2023) En Electronic music playlist, with a touch of classical strings orchestra. If you want to support me, you can buy a digital download with high-resolution AIFF and MP3 files here.
	Catacombs (2023) I bought in 2023 an E-mu Proteus/1. I already have a Proteus/2 since 1996. This track is an exploration of what I could do using both expanders together.
	Silk Dust Original Soundtrack (2022-2023) I wrote a soundtrack for my text adventure game Silk Dust (see below). You can stream it on SoundCloud, or buy it on Itch.io (16bit 44.1kHz AIFF or 24bit 192kHz FLAC, total length: 37 min 22 s)
	The problem of the musical scale (2002-2007) Building a musical scale has not been an easy task. In this article, I describe briefly the path that lead to the modern tempered system for the tune of musical instruments. I present the mathematical rules useful to obtain the chromatic scale as well as the cents scale.
	How to exchange musical samples via the MIDI SDS protocol (2003) The MIDI SDS (Sample Dump Standard) is a protocol developed at the end of 1980's to allow different musical instruments to exchange sound samples via a MIDI link. I wrote a small command line utility for Microsoft Windows, to send a WAV file with this protocol to a keyboard or a MIDI expander able to understand this format.
	belle.mp3 (3,4 MiB, 2005) Belle qui tiens ma vie is a very well known pavane, written at the end of XVI century by Thoinot Arbeau (anagram of Jehan Tabourot) and published in the Orchesographie book, a sort of renaissance dance handbook. It is the only piece which is completely harmonized for four voices. A pavane is traditionally a slow tempo dance, written in a two beat measure. Here I propose a version which is quite far from the original for what it concerns the rhythm, the harmony (yes, consecutive fifths are for good) and orchestration. Far from being a philological work, it is more a kind of a fairy tale dream.
	tulip_ballad.mp3 (3,9 MiB, 2007) Sometimes, I am somehow attracted by minimalism in the style of Yann Tiersen. My tulip ballad is a small test in this direction. This piece is based on an irregular decomposition (3+3+3+3+2+2 sixteenths) of a four beats measure.
	bwv639.mp3 (3,8 MiB, 2007) An interpretation of a very well known Bach piece, the BWV639, from Orgelbéchlein. I do not try to do an historical interpretation, but just a thought to someone who is very far.

Some vintage stuff I like...

	Restoration of a Revox B77 mk II reel to reel tape recorder (2024) En June and May 2024, I acquired and restored a Revox B77 mk II (HS model) reel to reel recorder. It is a beautiful object and I have a lot of fun with it recording my music.
