Send messages
Documentation for the "Send" section.
Keyboard
Keyboard allows you to send notes to a device with a virtual keyboard.
Desktop
Desktop version of the keyboard:
- 5 octaves are displayed
- Click on any note to send a note to the synthesizer.
- Transpose the keyboard by one or two octaves with the dedicated buttons (-24, -12, +12, +24)
If a note gets stuck, press it again to stop it
Mobile
Mobile version of the keyboard only displays one octave:
The octave to play can be selected with C1-C8 buttons. C4 is the default.
Tapping each note is necessary, sliding between notes has no effect.
System Exclusive
The SysEx tab allows to send arbitrary system exclusive messages to a synthesizer.
Be sure you know what sent messages do to your synthesizer. Sending incorrect messages may damage your synthesizer.
Do not send firmware updates or other large messages with synthsonline.com. The way the browser transmits midi data is not adapted to these kinds of sysex messages.
Send a system exclusive message
To send a message, just type or paste it inside the text field. When typing a message, messages can be detected as valid or invalid.
Valid message
Valid message means it is well formed. It does not mean the message is supported by the synthesizer. No synthesizer specific checks are made for system exclusive messages.
To send a message, it has to be valid. A valid message is a well formed system exclusive message. In such case:
Example of a valid message, detected as a patch:
Invalid message
Typing a system exclusive message that is not valid will:
- display an error
- make the send button inactive
Example:
Error will disappear and send button will be active as soon as a valid system exclusive message is present in the text field.
Invalid message means it is not well formed. It does not mean the message is not supported by the synthesizer. No synthesizer specific checks are made for system exclusive messages.
