Value To intensity – Blinking/Flashing LEDs
Hi Folks,
Im using a Yaeltex controller – in the set up of the device it is possible to select an option in the controller feedback called ‘Value to Intensity’. Basically the velocity value sent to the pad will dictate the brightness.
I am try to create a blinking/flashing pad – does anyone have any pointers for things I might be able to do in CSS to send velocity values to the pad to make it flashing. Something Like an on off function or even better a string on values modulation by step from 0-127 in a sine wave sort of pattern?
I received this response from Yaeltex – the manufactures of my controller.
The problem I see with the information they have sent me is the ‘SEND RAW MIDI DATA to Controller only seems possible for static values where as I need to send a constantly changing velocity.
“Value to Intensity feature will work when you send the velocity on the correct channel configured in Kilowhat.
By default this channel is 15.
Value to color feature will work when you send the velocity on the channel you configure for the switch feedback.
From the video, the data you are sending seems to be affecting the value to color feature.
You need to find a way to change the MIDI channel.
“Send RAW MIDI data” might help if you can combine it with the custom parameter you want to send.
Raw MIDI data consists of three bytes in hexadecimal format:
Byte 1: Command
For Note ON this command is 0x90 for channel 1, 0x91 for channel 2, 0x92 for channel 3 and so on.
Here you have to use the channel you configured on Kilowhat – 1, in hexa.
For example, for channel 15 the correct byte would be 0x9E.
Note OFF is similar but 0x80, 0x81, …
Control Change command ix 0xB0, 0xB1 and so on for different channels.
Byte 2: Note # or Controller #
This is the note number from 0x00 to 0x7F (0 to 127)
Byte 3: Velocity or Value
This would be the actual parameter you want to send, again, from 0 to 127 in hexadecimal.
If you find a way to send this raw midi data, the value to intensity feature should work.”
