Novation Launchkey 25 MK4

這一台還沒有寫 LED 回饋，OAV 不會讓它的燈亮，但每個控制項照樣可以彈、照樣送出各自的訊息。

個別控制項的說明

• pitch Pitch wheel: Novation says it sends pitch bend messages; the channel is not printed — it follows the Keys Channel (default 1), assumed.
• mod Default CC 1 per the Launchkey MK4 Components Guide (Mod Wheel/Strip tab: "default is CC 1"; editable in Components). Its MIDI channel is not printed — the Keys Channel (default 1) is assumed.
• k1 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• k2 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• k3 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• k4 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• k5 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• k6 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• k7 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• k8 The power-on Encoder mode is Custom 1 (Settings → Power On Modes), but Novation prints no default CC for it — the values are set in Components. CC 21–28 on channel 1 is a placeholder: CC 21–28 are the encoders' DAW-mode numbers (channel 16) in the Programmer's Reference. Check the number and channel in Components, or use 學習. Absolute vs relative is also a Components option (relative not assumed).
• sustain Sustain pedal jack: default CC 64 per the Launchkey MK4 Components Guide (Pedal tab: "default is CC 64"; editable). Channel is not printed — the Keys Channel (default 1) is assumed.

1. 一行嵌入

   不用 import map，也不用建置。可以改 layout，加上 hardware="ask" 就有「接上」按鈕。

   html複製

   <script type="module" src="https://openaudiovisual.com/packages/midi/element.js"></script>
   <oav-controller profile="novation-launchkey-25-mk4" readout></oav-controller>

2. 或用 iframe

   給只能貼 iframe 的地方。每個事件都以 postMessage 傳回來。

   html複製

   <iframe src="https://openaudiovisual.com/embed/controller/?profile=novation-launchkey-25-mk4&readout"
           width="720" height="413" style="border:0;max-width:100%" allow="midi"
           title="Novation Launchkey 25 MK4"></iframe>
   <script>
     // every control the visitor plays arrives here
     addEventListener('message', (e) => {
       if (e.data?.source !== 'openav' || e.data.type !== 'control') return;
       console.log(e.data.detail.signal, e.data.detail.value);
     });
   </script>

3. 送進 Ableton、TouchDesigner、Resolume

   你在畫面上彈的，會變成真正的 MIDI，從 macOS 的 IAC 匯流排或 Windows 的 loopMIDI 埠送出。步驟在圖鑑頁。

   html複製

   <!-- what you play on this controller → the IAC bus (macOS) → Ableton, TouchDesigner, Resolume -->
   <script type="module" src="https://openaudiovisual.com/packages/midi/element.js"></script>
   <oav-controller profile="novation-launchkey-25-mk4" midi-out="IAC" readout></oav-controller>
   <!-- Windows: midi-out="loopMIDI" · let the visitor pick a port: midi-out="ask" -->

   macOS：音訊 MIDI 設定 → MIDI 工作室 → IAC 驅動程式 → 勾「裝置在線上」。Windows 11：內建的 Windows MIDI Services 有 loopback（我們沒有實測）；舊版 Windows：安裝 loopMIDI、新增一個埠，用 midi-out="loopMIDI"。

function draw() {
  background(knob1 * 255);   // 1 · CC 21
  circle(width / 2, height / 2, 50 + knob2 * 300);   // 2 · CC 22
}

function padPressed(n, velocity) {      // n = 1…16, as in the table
  circle(random(width), random(height), velocity * 100);
}

function notePressed(note, velocity) {   // a key goes down
  circle(random(width), random(height), velocity * 100);
}
