I'm having a time figuring out an easier way to setup a min/max range for the input to operate within, sans using complicated chains of expressions and thresholds and etc.
Is there a "range" modulator that might be named something else and I'm just not figuring it out?
E.g. I have a scale module between an image and the output. I want it to never be less than 1.0 and never to be more than 1.1, but I want the audio input (0.0-1.0) to operate between the scale of 1.0 and 1.1
Currently to do this, I would set an expression X+1 to achieve the minimum, and if there was a "limiter".... I'd set it to 1.1
Theres gotta be an easy way to do this... Mathmaticians?
setting min/max range
Re: setting min/max range
Figured it out. Offset = 1, Clamp =1.1
Sorry to waste yalls time
EDIT: this still actually does not output as I wanted, as the value remains at 1.1 for the duration that the value exceeds 1.1, I am looking for something that compresses the value as it approaches the parameter (1.1) A limiter would be exactly what I'm looking for.... Do we have this?

Re: setting min/max range
Try:
Scale(.1)
Offset(1)
Scale(.1)
Offset(1)
Re: setting min/max range
This is closer, but still does not achieve what I want.
The value is now just 1.0xxx, and still going through the entire range of input.
I want this value to never be less than 1.0, and never be higher than 1.3, while being compressed as it reaches the target value of 1.3
A compression ratio of 10:1 or 20:1 would be similar to how an audio limiter works. I'm literally looking for a way to mimic audio compression.

Re: setting min/max range
Compression can be complicated. To get it the way you want, you will probably need to start with the Expression modifier. For some easy math, you can try something like: if (x<.5, x, .2x+.4). This means that 5x compression will be applied if the input volume is greater than 50%. So your output range will be 0 to .6. Then you can do Scale(.5) to make the range 0 to .3. Then you can do Offset(1) to make the range 1 to 1.3.
Overall I'm not really sure how you want this to work in your scene, but you should experiment and see what works well for you.

Re: setting min/max range
Thanks Eric! I didnt know I could use "If" statements in the expression field. That makes this much more handleable, and also much more powerful!
Re: setting min/max range
Here's what I've been trying to achieve with this compression expression. limiting the X and Y with compression makes it look much more like an actual spectrum response, which can now be applied to any image, shape, etc.
