need help with smooth draw for sequencer

[Nubeat7]

you all know the stock steplfo sequencer and the cool smooth curve..

so i adapted this a while ago into ruby but only with the bars but no smooth curve so i use the old one for this...

but i also want to do the smooth in ruby specially because the original is using a ramp, a float array to poly and an analyzer lot of stuff which is using audiostream cpu power, sadly i couldnt find a solution and i have no idea if it is possible and how..

i just could get a nice curve on the values but got lost on smoothing the spikes...

any help on that would be appreciated

thanks

What about reversing the order on the beziers one?
-looks pretty close, it just smoothing in the wrong direction.
IMO you could keep trying, I think you will get the bezier.

edit-sorry for confusing things,
the behaviour was different from what I remembered.
So- it's very close. Will keep playing.
btw- the curves you have drawn are very cool,
swapping out values makes them do all sorts of interesting things.

edit2- One argument for using the stream to draw,
is that it is the same operation as is applied on the audio.

edit3- Here is a mod on the beziers->

Will try and implement optional 2 point steps now, instead of points.

thanks nix, brought me a big step further, here is a direct comparsion of the stock and the actual ruby version with better bezierdrawing

it pretty close on smooth factors till 0.8

so i took the smooth methode and used it for the array and look here, it works

thanks for putting me in the right direction!

That's beautiful NB!
Will integrate in Entrancer.
I was applying your optims,
and ran into an issue with envelopes/voice management.
So I have fixed that,
it made the sequencer screwy and wouldn't release one voice.
Back to emplacing the optims,
this one is a gem IMO.
Will send a pm in the next couple of days,
but what I have in mind is ASMing the stock envelope.
I can try learn,
but do yous want one?
That's neat you used the function in Ruby,
that filter works equally well as a Ruby codebox
TY!

thanks nix,

hope you can fix the envelope issue..

here is the final version of the steplfo including bars and smoothcurve (and fading colors )
i also filled the smoothed area with color..

the 2 types "positive" and "positive/negativ", like you know it from the stock one, are available too

the only thing missing are the value steps (stepsV)

Here is just the drawing- without the mouse controls.
This is the component I have replaced in my synth,
I use a method with no loop to draw the bars,
and mouse controls are in there.
The looped bars were crashing frequently,
but I am happy enough with them now.

Thanks very much NB,
The envelopes issue is dealt with but I had to ditch the Assembly version.
