自分が初めてMIDIで色々
通信してみた
小野隆之/るしわん
@tkyko13
プロトアウトスタジオ(#protoout)の講師やってます
● 音楽関連に興味ある学生が2/6人
● Qiitaトレンドに6人全員が載ったことも!
● クラウドファンディングでサクセス目指して奮闘中!!
○ 12月末から2週間の予定
● MIDIに関して、初心者の自分が
調べてみてわかったこと
● 買った基板を試してみた
● MIDI周りの技術を使ってみた(Bluetooth MIDI)
今日の発表内容
全体的に自分は今こんなのにワクワクしてますよ発表 …
MIDI? Musical Instrument Digital Interface
ファイル拡張子と端子で同じ名前使っていることは知ってた
● 3種類
● 両脇2ピンは使ってないらしい
● USBでも同じ内容のデータ
○ 音色、音程、強さ
○ 同期信号
この前のメイカーフェア necobitさんのブース
音楽に合わせてカチャカチャ鉄琴を鳴らしていた
基板(MT-4)を購入
MIDIデータからソレノイドなど4つ動かせる
帰りにアキバで…
PC→MIDI
● 3.5mmジャックからMIDI変換
(ない)
● MIDIインターフェース(高い)
     ↓
後日M5Stackのモジュール
を購入
M5Stack→MIDI
M5Stackの演奏からファンを回す
● PC関係なく、M5StackでMIDI演奏
● 演奏データをMT-4が受け取りファンを
動作させた
● 自作MIDI楽器の伴奏
○ 傾きセンサーなどの様々なセンサー
○ Core2のタッチパネル
● ソレノイドで叩く
● 笛自作
MIDIケーブル
MIDI生成
音程が48番だったら
デジタル出力
動画
Bluetooth MIDIの発見
● USBケーブルで同じようなデータ送るものもあるし確かにあってもおかしくない
● ちなみにWeb Bluetoothから利用することもできるみたい
○ https://qiita.com/ryoyakawai/items/200b3b05d8bd0096f68d
MacでのBluetooth MIDI
https://support.apple.com/ja-jp/guide/audio-midi-setup/ams33f013765/mac
「Audio MIDI設定」 「Garage Band」
Garage Bandからファンを回す(途中)
● PC(ガレージバンド) →[BT]→ M5Stack →[MIDI] → MT-4(ファン)
● サンプルがなかったのでArduinoのプログラミング中
既存のアプリケーションから
動かすの楽しい!!
iPhoneのGarage BandでBluetooth MIDI
https://support.apple.com/ja-jp/guide/garageband-iphone/chse356a0321/ios
でも信号送信できないんだって…
