I would like to know if all buttons are toggle or if make sense or ita possible to have some buttons as momentary (effect its only active wjile button its been pressed, when release the video returns to original state)
By default they are all 2-state toggle based parameters, but I don’t see a problem with putting momentary behavior as a configuration option on our development list.
another question I have is effects/mode buttons can be used with some sort of transition or easing or instantaneous the change when the button is pressed? if so th transition speed could be configured?
No, all of the transition based parameters are on the sliders with CV inputs already. The buttons are only used for parameters that have a binary state. If you want to transition from one of the binary effects to unaffected input, this is what the keyer (and alpha channel input) are designed to do. Or external compositor.
I do like what you’re suggesting – it’s similar to the intention behind the pushbutton control for the animation generator on Visual Cortex (push to transition, use rise/fall to set easing and transition speed.) But in terms of the LZX system architecture, it’s something to put on an animation envelope / sequencing module to be used as a CV source.
With the internal feedback loop, each control cascades to a series of related actions in the buffer repetitions – so there are many very performable transitions just with slow slider movements; especially moving two sliders at once, or moving one slider with LFO modulating another, etc. With analog we are used to creating or altering just a single element at once when a knob is turned, whereas in the buffer feedback context the echoes create a whole sequence of complex movement based on simple input motion.
