Trouble animating steps in sequencer

I'm a relative newbie at reaktor (though a seasoned programmer). I've been working on building a general-purpose 16-step sequencer, and I've got it mostly working. It can vary step length from 1 to 16, allows users to set levels with the mouse (mouse area & multi display), saves values (snap value array), working pretty cool.

But I'd like to make the current step a lighter color, so the user can see the steps cycle through. My ultimate project will have 8 sequencer lanes controlling 8 different effects, and mix them a la infiltrator, but right now I'm just taking baby steps and building the pieces I need.

I tried to use an iterator to update the color for the current step and the previous step, to make the current one a little lighter and revert the previous step back to its original blue state, but instead, the color remains the same blue but the height of the steps are jumping around.

I've never used the iteration module before, and I'm not sure I understand it. I want it to only update the previous step & the current step… should the "N" param be set to 1 or 2? Docs aren't quite clear, and it goes by too fast to monitor by eye.

I've uploaded the ensemble. The macro in question is called 16 Step Slider Display.

Any feedback would be most welcome; I've attached the ensemble. Also, is there a good ensemble that implements this correctly that I could study?

Thanks for all your help!

I haven't properly read your issue and didn't try your ensemble but just quickly like that you can set the iterator to go slowly in the options…."limit speed" and then you choose the number of iteration per second,this way you could see what happens visually.

That's a great tip!

I'm clambering up the learning curve. I hacked around the problem in another way… I created another multi display, very narrow, and basically implemented a stepwise progress bar. Having it be a separate multi display made all the problems of multiple processes changing the same display go away… each process has its own display. But I'd still like to solve the problem, as I'm sure to encounter it again.

Simple way to do this would be to drive the Iteration with your trigger N=1, Inc=-1 - feed this into an Order 1. Idx 2. RGB inputs. You don't have to feed the X/Y inputs to do that - I would use separate event chains for different parameters & merge the initializing output events from those into your Idx input

Ok, thanks. But now a deeper question: how do I tell how often a value is generating an event? If I hook up a const to a wire inputting a value in the param of the multi display, does that value stay available for every action feeding a new idx value?

silvermoats

Nope, they have to be triggered with something after Idx - Value module should work for that. I would drive a Counter with a '1' value to see that it's working, it should increment +1 with each step

Might be a good idea to prototype this with the Event Table, then you can effectively have 8 (Y-axis) sequencer lanes of X # of steps & a built-in display within a single module.

Harry LeBlanc

Yeah, that's my approach. Get one to work, then duplicate it 8 times for the 8 lanes.

I've got a version of this more or less working. (I'm having problem with adding swing, so I think I'll disable it for now.) When I get it working, I'll upload it for your amusement. It's pretty decent, and useful.

Thanks for all the support!

Okay, here's the simple version of the sampler, which I think is working.

Let me know what you think. I'm working on enhancements, but as is, I think it's useful.
