ice (2002)

A piece composed for my original album, which was planned to be released from CODE Project( Although the album was scheduled for April 2002, I've only finished this single piece for it...... And before I was able to compose another, the CODE Project have closed its activity and I've lost the chance to release my own CD.... Anyway, I've used sounds that I recorded when traveling to Niigata. A sound of ice breaking in the lake was so beautiful, that I had to record it using my portable DAT.

CODE Project(よりリリースされるはずだった僕のアルバム用に作成した作品。2002年の4月リリース予定だったわけですが…、結局この1曲しかできず、しかも2曲目に着手する前にCODE Project自体が終了してしまったという…。それはいいとして、この作品では新潟に旅行に行った際に録音した音を加工して用いています。ある湖の表面に氷が張っていて、その上に氷のかけらを投げるとなんともいえないきれいな音が鳴っていたので、なぜかその時持っていたDATで録音したわけです。

musyosII (1995)

This piece was made for live performance at Disinfectant Electronic Music Party on Dec.15,1995. It's done all based on MIDI. For the first time, I used Groove Quantization function in Opcode System's Vision MIDI sequence software. The title is a mixed letter of a phrase. Guess the real title!

これは、95年12月に大学のキャンパス内で行ったライブ用に作ったもの。当時出たばかりのOpcode Vision 2.0のグルーブクオンタイズばかり使っているのが今となっては少々恥ずかしいか(^^;)。

coldsleep (2001)

| トラックバック(3)

This is a piece for a secret live done by Ryuichi Sakamoto, Yoshihiro Hanno, me and Atsushi Tadokoro at Earthday Tokyo 2001. Of course, Mr.Sakamoto and Mr.Hanno was the main performer and I was just a front act, but was a nice experience doing live music out in the field. The title comes from the samples I used.

これは、2001年のEarthday Tokyoの時に行われたhoonのライブのために作ったもの。メインはもちろん坂本さんと半野さんなわけだけど、屋外で気持ちよく音を出せたのはいい経験。タイトルは、作品内に使われているサンプルからきているもの。

nightmare (2000)

A piece for GNUsic Project's second CD. Entirely composed using Csound, AudioMulch, GranuLab, Perl, and CoolEdit Pro. Final mix down is done using CoolEdit Pro's multi track mix feature. The strings like sounds were generated from YMO's "Light In Darkness", which is one of my favorite ;). The samples were analysed usind pvanal and then processed by score files generated from my original Perl script.

GNUsicプロジェクトでの2枚目のCD用に作った作品。CsoundAudioMulch、GranuLab、perl、そしてCoolEdit Proを利用した。ミックスダウンはCoolEdit Proのマルチトラック機能を用いている。ストリングスのように聞こえる音は、YMOのLight in DarknessのフレーズをCsoundのPhaseVocoder解析コマンド、pvanalで分析し、オリジナルのperlスクリプトで生成したスコアを元に合成されたもの。

My first composition all based on Linux and Windows95. I didn't use NeXT or Mac for the first time!(Is it good or bad?) This piece experiments with Granular Synthesis and composition based on Markov Proccess. I've analysed J.S. Bach's Air on G for the Markov Proccess. Granular Synthesis was done mainly on Csound.

This piece is dedicated to one of my best friend Chiaki Ikegami, who passed away in a car accident on Nov. 1998.

Experiment7 by yasaka

experiment 6 (1997)

My third composition all generated and processed on NeXT. The goal with this piece was to use algorithmic composition while maintaining tonal scale. I used dorian scale for this. Algorithmically composed part is the second half of the piece, while the first half is based on sounds processed through Phase Vocoder.

This piece was selected for ICMC(International Computer Music Conference) '98 held at University of Michigan this October.

NeXTのみを使った作品としては3作目。この作品では、調性を保持したまま生成するアルゴリズミックコンポジションに挑戦している。調性はドリアンスケールを用いている。アルゴリズミックコンポジションで作成したのは後半部分になり、前半はPhase Vocoderを使った音響処理を行っている。

なお、この作品は1998年10月にミシガン大学で開催されたICMC(International Computer Music Conference)に入選した。

Isoidekuchidesue (1996)

This is my second composition made all on NeXT Computer. I had two goals in this. One was to use convolution and the other was to compose from few samples as possible. The first one, I did an convolution of a choir and a breaking glass. For the second goal, the samples I used in this piece are the choir, breaking glass, and a phrase saying "Isoide kuchi de sue!" taken from an album by Snakeman Show.

256lm (1995)

256lm was composed for "4 nen ten", which was an art event by senior students in January,1995. Although I had this piece ready, I wasn't able to perform it, because I played too long before 256lm... Well, things doesn't always go the way you want. But this is my favorite so far:-).

chaos (1994)

This was my final composition for under-graduate degree. The title "Chaos" came from one of the concepts and from the mental situtation I was in while composing this piece.

There are two main concepts. One is morphing of two waveforms. It was done by taking substraction of each samples and adding or substracting data. For this, I excpected to have some synthetic effect when morphing one waveform to another, but unfortunetaly, it was just cross fading two sounds. I should have tried morphing on the spectrum domain and not the time domain...

Second concept was to use the logistic equation of chaos as a pitch of notes. This method produced quite a complex movement of notes with just a single equation.

for 4 crazy bells (1991)

One of the very first composition done using a patch created on Max. I've used Max for producing random MIDI notes and recorded them on to EZ Vision. On EZ Vision, I've looked for phrases that interested me and compiled it as a single piece. I've used Roland's rhodes model 760, which is kind of a 76 keyboard model of U-20, as a MIDI sound generator.

Maxのパッチを使って作った最初の作品。この曲では、Maxを使ってランダムなMIDIノートを生成し、それをEZ Visionで録音。録音した中から面白いフレーズを探し出し、それらを一つの作品として組み合わせた。音源は、ローランドのrhodes model 760という、U-20を76鍵化したようなものを利用した。
