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?
To send values to other channels, all you need to do is make a fake button on your controller template with the channel and value you need and send feedback to it. You might need to do this in a Reaction because I think the LED feedback in the other Mappings is only sent to the Listener you assigned.
I have also tried (and failed) sending raw MIDI data dynamically inside an Action Block (on my Nektar Pacer). On the Pacer there’s a little display that can show 5 letters; I wanted to make scrolling text for it. But an Action Block doesn’t continually update Ableton on its output. The Reaction just stalled the program until it was finished and then showed the last result of the order of letters on the screen.
There might still be ways to use dynamic Raw MIDI sends that I haven’t tried yet:
– Use multiple Action Blocks, where each sends the next piece of data. The problem is that this doesn’t work infinitely, but you might get a few blinks in before it settles (if it works at least). Another problem is that the blinks would probably be over very fast, and if you try to space out the timing a bit (which is possible with Python code) it might stall your software until it has finished the Reaction. But the only way to know for sure is test this.
– Store a value inside a Modifier (e.g. 0 = dim light, 1 = bright light, start with 0). Then make a Reaction send Raw MIDI based on what is stored in that Modifier and then update the Modifier so it is the other number. In other words, if the Reaction gets the 0 from the Mod, it sends Raw MIDI to the Controller to tell it to dim its light + it stores a 1 in the Mod, so that the next time this Reaction is called, it will send Raw MIDI for the bright light to the Controller. Then you need to set up a way inside Ableton to call this Reaction dynamically. My idea is to set up a Clip that changes automation data periodically and have the Reaction Listen to the Automation of that specific Clip.
