Control your Meris Enzo pedal with your web browser. View all the pedal's settings at once.
Note: if you can switch presets from the editor but nothing happens when you move a control, that means the input and output devices are correct but that the MIDI channel is incorrect.
If you can't get the MIDI communication working, check the following on the Enzo:
You must use a browser that supports the Web MIDI API specifications.
Currently, only the following browsers support the Web MIDI API:
Web MIDI is not supported under iOS (iPad, iPhone). The editor may work under Android but I did not test it.
Scroll down to MIDI in the browser to get more information about how to check and setup MIDI in your browser.
Once you have your Enzo connected to the MIDI I/O interface, you must configure the editor:
The editor's preferences (settings) are saved in your browser's Local Storage.
The square buttons 1 to 16 on the top left of the editor allow you to directly select one of the sixteen editor settings.
|No communication with Enzo. Preset not modified since loaded.|
|No communication with Enzo. Preset has been modified since loaded.|
|Communication with Enzo OK. Preset not modified since received.|
|Communication with Enzo OK. Preset has been modified since received.|
A normal (or slightly dark) background indicates that the editor is not able to communicate with the Enzo.
A yellow background indicates that the editor is able to communicate with the Enzo.
No dot in the preset selector means that the preset has not been modified since it has been loaded from a file or received from the Enzo.
A dot in the preset selector means that the preset has been modified since it has been loaded from a file or received from the Enzo. In that case the dot means that the values in the editor (and in Enzo when communication is working) are different from the values stored in Enzo memory (or saved in the preset file, when loaded from a file).
If you want to keep your current values and store them in the Enzo memory then you have to use the SAVE command from the menu. See next chapter.
From the Meris online FAQ:
To save a preset, press one of the footswitches on the preset switch, modify your sound, then hold ALT to save.
Note: you can not save to preset number different than the current number.
To save the preset, use the SAVE menu option in the editor or press and hold the ALT button on the Enzo.
Note: if you save the preset on the Enzo (with ALT button), then you have to select the preset again in the editor to make sure it remains in sync with the Enzo.
Presets can be stored in files (binary .syx files) and, with this editor, presets can also be stored as URLs.
When you load a preset, it is sent to the Enzo and replace the current _live_ values. It does not replace the preset _stored in memory_. If you want to keep the preset you loaded in the Enzo, then you need to store it, either by using the menu SAVE command of this editor or by pressing and holding the ALT button on the Enzo.
Press the Tab key on your keyboard or click "close" near the EXP slider in the editor to toggle between the two sets of values stored in a preset.
When you edit the second set of values, the control's name are written in lowercase. They are written in uppercase when you edit the default set of value.
The EXP slider allows you to simulate an expression pedal connected to the Enzo.
The value displayed next to the slider is:
Now, when you move the EXP slider you must see the controls' values morph between the normal and second values you set.
Do not forget to save these values in Enzo preset memory if you like them. Use the menu SAVE command.
For each of its knobs, the Enzo stores two values:
When you move the expression pedal between its min and max position, the Enzo will morph the values between those two sets of values.
Please read the Meris Enzo User Manual, section 5, for more informations.
This editor lets you define the values for the two positions of the expression pedal.
By default, the first set of values is always used. To edit the second sets of values you have to click on EXP down:
The depressed down button means you that you are editing the second set of values.
The down text will be highlighted and also all the knobs names will change to lowercase. This shows you that you are now editing the second set of values.
Note: you can also use your keyboard TAB key to toggle between the two sets of values.
When you are editing the second set of of values, you can use the copy button to copy the first set of value to the second set.
To switch back to the default set of value, simply click down again. The down text must change back to black and the knobs names must change back to uppercase.
You can now use the EXP slider to smoothly morph between the two sets of values. The editor will interpolate the values to show you what the Enzo is probably doing. But there is no guarantee about that. The editor does a linear interpolation. Maybe Enzo does a different kind of interpolation.
If you want to use this with a real expression pedal connected to the Enzo (and thus without MIDI), do not forget to save your preset with the menu's SAVE command.
The editor can update its URL to include a representation of the current settings. This is like appending a hexadecimal SysEx to the URL.
When you access an URL containing such a parameter, the editor will use it to set the value of the knobs and switches. It will also send these values to the Enzo.
So you can use URLs as preset bookmarks!
If you already have the Enzo running with a nice preset and you connect it to the editor, maybe you don't want the editor to overwrite this preset because you open it with such a URL. To avoid this case, in the editor preferences, you can choose the behavior you prefer:
You can manually update the URL with the URL command in the menu or you can let the editor automatically update it. You can set this in the editor preferences:
The REC button also lets you start at will the auto-updating of the URL.
REC is automatically stopped if you use your browser's history.
Use REC to record all your changes and later on travel back in time!

IMPORTANT: please keep in mind that the editor only has the possibility to read the saved preset from Enzo. It can not read the current values of the controls. These values may be different from the one saved in memory (saved as a preset).
Also, do not forget that each time you access a "Alt/2nd layer" value, the preset is saved (see Enzo User Manual Section 7, page 9).
It is therefore recommended to always select a preset from the editor as first action after having opened it. After that, unless the MIDI connection is interrupted, the Enzo and the editor should always remain in sync.
The editor can receive SysEx from the Enzo. You can use this possibility to update the editor with the current preset of the Enzo. You have two possibilities to synchronize the editor with the Enzo:
Note: while you hold the ALT switch, the Enzo will save the preset before sending it.
The editor can become out-of-sync with the Enzo in that situation:
To avoid this problem:
If you can't get the MIDI communication working, check the following on the browser:
1. You use a browser that supports the Web MIDI API specifications.
Currently, only the following browsers support the Web MIDI API:
2. The Web MIDI is not blocked by the browser. See below for information about this feature in Chrome.
The first time you access a web page that uses the WebMIDI API, the browser will ask you for permission.
You need to click "Allow" to authorize the application to use the Web MIDI API.
If you refuse access, the application will display the following message:
Waiting for MIDI interface access... ERROR: WebMidi could not be enabled.
You can change the permission at any time:
Chrome display an icon in the URL to remind you that you are on a page that have access to MIDI. You can click this icon to access the MIDI permission settings.
You can also access the MIDI permissions via the browser Settings page.
In Chrome, follow this path: Menu Settings / Advanced / Content settings / MIDI devices
You can also open the Settings page and search for "MIDI".
If you have a Mac, use the Audio MIDI Setup application:
If you use a Mac, check out the tools available at https://www.snoize.com/.
This editor will not work in Firefox, Safari, IE or Edge because these browsers do not support the Web MIDI API.
This editor will not work under iOS (iPad, iPhone).
This editor has mainly been tested with Chrome on a MacBook pro running the latest OS release. Some tests have been done with success with Chrome under Linux Mint 17.1 and with Chrome under Windows 10.
Still under active development. Feel free to log bugs/issues.
A big thank you to Meris for having provided precious information regarding the SysEx data. This editor could not have been so complete without their support.
