关于Sound Module

一个简单的免费附加应用程序播放MIDI音符和负载的用户下载的SoundFonts。

This is a free add on sound module app for my existing music app (See photos) and 3rd party musical app.

1. "Micro Key Player - an usb keyboard to phone piano" and

2. "Volca Midi Player - an animation of falling note with option to play on external midi keyboard"

The sound module is open to any android app that want to play midi notes.

With this sound module, you have default 128 realistic musical instrument sound to play with. They have way better sound than my above 2 apps. And the key to sound response is fast. In addition, you could search for free soundfont on the web and download to your phone via your browser. Please download your .sf2 file to your sdcard folder or sdcard subdirectory. Sound module can load these downloaded soundfont and right, you can have unlimited instruments in your mobile phone.

--- For 3rd party developer too ---

It is very easy to add midi capability to your app. To use sound module, you only need to send an intent to it. The sound module service will automatically start with the intent. Here are some examples

1. To play C4(60) note. Add an intent in your code.

Intent intent = new Intent();

intent.putExtra("key", 60);

intent.setComponent(new ComponentName("com.appspot.soundmodule", "com.appspot.soundmodule.SoundModuleService"));

startService(intent);

2. To stop a note:

Intent intent = new Intent();

intent.putExtra("key", 60);

intent.putExtra("velocity", 0);

intent.setComponent(new ComponentName("com.appspot.soundmodule", "com.appspot.soundmodule.SoundModuleService"));

startService(intent);

After user has installed sound module, your app is able to instantly send note on to it and play midi notes. Think of it as a add on sound module for your app. Sound module is free for all users and developers. There is no license fee or whatever agreement to use it.

Why is it free?

As I develop a music app, I find that android does not have built in sound font loader. And there is hardly any answer on the internet. After spending some sleepless nights, I manage to learn about what is sound (sample rate, frame rate, bit per sample, stereo channel) and the api (soundfont, c programming, jni, fluidsynth). The coding is tough but the use is simple. Since all my apps uses the sound module, I might as well release it to other users. It is really tough to learn jni and most developer only want to produce midi note. So why not release a standalone app for other people to benefit. No need to go through what I have, just to produce some realistic sound in android.
