midi audio
版本
版本V2023.4.28全新版本
开发者已放弃V2023.3.5的维护。物理硬件说明
- 最低配置 双核4线程
- 硬件不同，差异可能较大，此程序在10核20线程的Windows10 x64 pc机上编译通过。
支持 nodejs 和 Vue3
支持同步和异步处理
任务、代码说明
- 安装 npm i @psweb/midi
- 配置参数
-
//主旋律参数设置
midi.setVolume(0x7f); //音量设置
midi.setChannel(10); //通道设置
midi.setSleep(460); //节拍设置
midi.setTonesID(35); //音色设备设置
-
//主旋律参数设置
midi.setVoice("Volume", 0x4f); //音量设置
midi.setVoice("Channel", 5); //通道设置 0-1是钢琴专用通道
midi.setVoice("Sleep", 280); //节拍设置
midi.setVoice("TonesID", 50); //音色设备设置 0-1 channel时 Tones无效
midi.setVoice("Print", 2);//屏幕打印 0-5打印各类运行代码于终端
midi.setVoice("LiftThe", 0); //升降调[...,-3,-2,-1,0,3,2,1,...]- 两种主旋律参数设置 ，都可以使用，采用其中一种。
- 工程规定
import * as midi from '@psweb/midi/midi'
midi.midiOpen()
{
...
//所有的任务都在{}中设置、配置和运行
};
midi.midiClose();- 播放
//1.播放池
