I like using the stepper in the sampler to provide random values (by randomizing the points) for each trigger.
However I don’t understand if I can lower the amplitude of the modulation.
In fact what I would like is having the stepper act as bipolar modulation with controllable amplitude (lower is negative, upper positive, and middle is null).
Is that possible?
For bipolar,unipolar conversion,the formula is based on
output = input (/ or *) 2 (+ or -) 0.5
Something like that…This is a good approach
maybe someone who have done it on renoise will have a better formula
My brain is out of energy today
(PS:It seem that there is a connection between Renoisers…Yesterday I have begin to think about a parameter randomizer via “formula”…A form of “perlin noise”)
If you set the stepper to the * (multiply) setting, the Input slider should let you set the amplitude. Just make sure you leave the stepper’s polarity set to the default.
But let’s say you want to apply a slight change around a value. Let’s take volume as an example.
I want to have a slight volume change around a value I set.
If I use the multiplier, then the modulation slider is effectively the modulation amplitude, buut it’s always in the range from 0 to the slider value.
What I am asking for is to have the slider value as the center - corresponding to the center of the stepper - and an additional control for the stepper amplitude around the center.
I’d be fine with setting the minimum value and unipolar amplitude instead of center and bipolar amplitude.
I hope that makes sense
LFO device can’t make what you want?
Input (at left) * stepper + bipolar enabled (at top right)
The “input” become the amplitude controller
?
Yes I can put the stepper in * and bipolar. But it will not behave like I want. It will multiply the slider value by the points values, which tange from 0 to 1. What you get is a modulation that goes from 0 to your slider value.
So when I randomize the pattern and apply to the volume, I will get notes that go to complete silence and notes that go to the slider value.
What I would like instead is going slightly above or below the slider value (or both bipolar case).
So what we are doing now is:
out = in * slider * stepper
With stepper ranging from 0 to 1.
But what I would like to do is:
out = in * slider * (1 + amp * stepper)
With stepper ranging either from 0 to 1, 0 to -1, or -1 to 1 - ayof these would be ok.
And amp probably having the same range as the slider.
This way I could apply slight volume variations on each note for example.
The closest I can get is to use the LFO in S&H mode with the lowest frequency - but I want a random trigger, I don’t want it to modulate while playinng the sound (which can occur even at the lowest frequency).
Also the stepper and S&H are fundamentally different in S&H is completely random
in bipolar mode, stepper go -1 to 1
That’s true, but how can I control this amplitude and have he result added to the slider value?
Look exaclty at the second picture I posted
It a multiplier,but act as a divider
Ok, that’s on the pitch.
Now put it on the volume - your lowest point on the stepper will be silence. I want to be able to have a higher lower point.
I think It will do the work for bipolar to unipolar conversion for example
/2 + 0.5
I don’t see clearly what you want…I give you ideas
My intuition says that a macro controlling both Input and an Operand at the same time could do this, but I’m not quite sure how to set it up.
Why not just change the stepper values so that it’s within the range of volumes that you want?
If you want a more complex solution, you can use operand devices set to their various math functions, to Target and restrict the range of values output. In this case an operand set to multiply, followed by an operand set to Plus, with values dialed in to create the behavior that you want
Alternatively, you can use an LFO device set to random, with a small amplitude, and minimum frequency value to trigger random variations in amplitude (or any other modulation destination) on keypress, around the input slider value
Hope this helps
Can you put a hydra after the stepper, set the hydra input as the destination of the stepper and then pick a destination of a Hydra out. You can then define precisely the range of modulation of the hydra out? Im not in front of renoise right now but i think this is a good solution?
