将PlayLooping()与节拍器一起使用 [英] Using PlayLooping() with a Metronome
问题描述
我使用SoundPlayer类构建了一个节拍器，以激发各种节拍.
使用的wav文件是单独的鼓/贝斯/发情节拍...每个文件一个节拍.
在节拍器上，每个按钮(每个按钮用于不同类型的节拍)也是一个单一的节拍，在按一下该按钮时播放节拍
我想做的是将各个节拍链接在一起，使其像节拍器一样演奏，您可以拥有低音鼓，军鼓，木刻或低音吉他声音来练习吉他.
我现在使用PlayLooping()(临时)C#方法工作，但是它只是随机循环每个节拍，并且我无法控制节拍的速度，显然我需要做，因为我只想让它在节拍器的4/4定时(通用定时)格式.
我在节拍器的底部有一个滚动条，希望以此来控制节拍的速度.有什么想法吗?
Hi,
i have built a metronome using the SoundPlayer class to instigate the various beats.
The wav files used are individual drum/bass/snaredrum beats...one beat per file.
On the metronome each button (one button each for the different types of beat) is also a single beat that plays a beat onClick of the button
What i would like to do is link the individual beats together so that it plays like a metronome and you can either have a bass drum, snare drum, woodblock or bass guitar sound to practice guitar to.
I have it working with the PlayLooping()(temporarily) C# method at the moment but that just loops through each beat randomly and i cannot control the speed of the beats, which obviously i need to do as i just want it to play in a 4/4 timing (Common Timing)formation as per a metronome.
I have a scrollbar on the bottom of the metronome with which i was hoping to control the speed of the beats with. Any ideas at all?

推荐答案
您只需要使用Timer来调用播放类似声音的方法
You just need to use aTimerto call a method that plays the sound something like this
private void buttonBassDrum_Click(object sender, EventArgs e)
{
SoundPlayer soundToPlay = new SoundPlayer(Properties.Settings.Default.BassGuitar);
timer = new System.Threading.Timer(new TimerCallback(PlayBeat), soundToPlay, 0, 60000 / beatsPerMinute);
}
private void buttonSnareDrum_Click(object sender, EventArgs e)
{
SoundPlayer soundToPlay = new SoundPlayer(Properties.Settings.Default.BassDrum);
timer = new System.Threading.Timer(new TimerCallback(PlayBeat), soundToPlay, 0, 60000 / beatsPerMinute);
}
private void PlayBeat(Object soundToPlay)
{
//Play wav sound
SoundPlayer currentSound = (SoundPlayer)soundToPlay;
currentSound.Play();
}
这假定您的ScrollBar值代表每分钟节拍数，并存储在窗体级别声明的int beatsPerMinute中，并且计时器在窗体级别声明为System.Threading.Timer.我还使用应用程序设置"存储了wav文件的位置，因此Properties.Settings.Default.BassDrum代表了wav文件.
要更改每分钟的节拍，您可以在scrollBar.Scroll方法中执行此操作
this assumes that your ScrollBar value represents Beats Per Minute, and is stored in an int beatsPerMinute declared at form level, and that timer is declared as a System.Threading.Timer at your form level. I also used Application Settings to store the wav file location thus Properties.Settings.Default.BassDrum represents a wav file.
to change the beats per minute you could do this in your scrollBar.Scroll method
private void scrollBar1_Scroll(object sender, EventArgs e)
{
beatsPerMinute = scrollBar1.Value;
if(timer != null)
timer.Change(0, 60000 / beatsPerMinute);
}
希望对您有帮助
Hope this helps
首先非常感谢您，深表感谢！
我已经调整了代码，但收到异常错误:"AttemptingToDivideByZero异常"在这里尝试/捕获就足够了吗? (我是新手)

Firstly thankyou very much for this, hugely appreciated!
I have adapted my code but am getting an exception error: "AttemptingToDivideByZero Exception" would a try/catch be sufficient here? (i am a newbie)
