# Requirements &amp; Limitations

:warning: This application requires a browser that support the [Web MIDI API](http://webaudio.github.io/web-midi-api/).

Currently, only **Chrome 43+** and **Opera 44+** support this standard. This app will therefore _not_ work in Firefox, Safari or IE.

The Chrome browser is highly recommended.

This app has mainly be tested with Chrome on a MacBook pro running OS X 10.11. Some tests have been done with success with Chrome under Linux Mint 17.1. 
The application has never been tested under Windows. Any Windows feedback is very welcome.

Still under active development. Feel free to log bugs/issues. This is a development I'm doing during my freetime.

# Usage

1. Open https://sysex.io/bs2/
2. Allow the browser to use your MIDI devices
3. If it's not already done, connect your Bass Station 2 to your computer.
4. When the Bass Station 2 is connected the application logo will glow. 
5. Move a dial or a slider on your Bass Station 2, the corresponding on-screen control must move accordingly.
6. Move a knob or a slider in the application, the corresponding parameter must follow in the Bass Station 2.

The logo glows when the Bass Station is connected and recognized by the application:

Bass Station 2 is disconnected:

## Application Menu

### Favorites

Open the Favorites panel. You can save and recall your favorites patches here. Your favorites are saved in your
browser's local storage. No files are created.

A favorite is simply a URL with the following format:

http://<domain>/bs2?sysex=<sysex-data>

Example:

http://<domain>/bs2?sysex=f00020290033000000000000000000006000004804037d7e0220100f777801004340200000ff7c00000000000f78000008200000077800004000000f700000000000126000000000001a4000202004001f190f6923797c7e3f1f5f6f70017c7e403f4f6770017c7e401f4000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000f7

### Init

Reset the application and the Bass Station 2 with the default values (init patch).

### Randomize

Randomize the parameters according to the _Randomizer settings_ defined in the _Settings_ panel.

### Sync

Sync the application with the Bass Station 2. This is done by sending a request-for-sysex to the Bass Station 2.

### Load patch

Open a dialog allowing you to select a sysex patch file (file with `.syx` extension). One loaded the patch is sent to the Bass Station 2.

### Save patch

Open your browser's Save File dialog to save the current patch as a sysex dump file (file with `.syx` extension).

### Patch sheet

Open a new window with the current patch displayed in a ready-to-print layout.

:bulb: With Chrome you can even easily create a _PDF_ file.

### Midi

Open a samll window that will dump all the MIDI messages sent or received.

### Settings

Open the Settings panel. Within this panel you can configure:
- the **MIDI channel** to use to communicate with your Bass Station 2 
- the **randomizer**

### About

Display the _About_ dialog.

# Bass Station 2 MIDI messages

The MIDI parameters are documented in the official Novation Bass Station 2 user manual.

## SysEx Dump

The application is able to receive and decode SysEx dumps coming from the Bass Station 2 ("FN-Key _Global: Dump_") as well as .syx patch files.

The SysEx dump format is not documented by Novation. I have reverse-engineered it and you can find the result
 in my other project [BS2-SysEx](https://github.com/francoisgeorgy/BS2-SysEx).
