exactly values for speed slider

[jur1...@gmail.com]

how can I set a speed slider with sending a midi controller 0-128 to an exact value   1x,2x,3x  is there a function that helps?

I do this in Cantabile on a tempo Source binding




and this in Lightjams
midi.controlraw(15,3)/2

That gives me a 1.0x speed at 120bpm.

A midi value is between 0 and 127. If you use midi.noteRaw or midi.controlRaw, you'll get the exact midi value. If you use it to control a speed slider, 20 is 1x, 40 is 2x, etc.

....that means to send the right values from cantabile directly  (20,40,60,80,100)

,to manipulate the values in cantabile......

and not to latch this values in Lightjams ? .....is this correct?

It maps the tempo from C3 to what lightjams wants.

so 60 bpm in Cantabile ends up as the Midi value of 20 when it gets to lightjams. My lightjams formula midi.controlraw(15,3)/2 takes this raw value of 20 and divides by 2 and makes it a percentage to give me 10% which is 0.5x speed

...thanks for your help

this is not what I want to do....... but now I better understand what I have to do to make my slider work for me

I will use my effect rack slider for the rack effects for (0,5x,1x,2x)  (left, mid, right - sliderposition)

I also will route my slider values to a specific range (in this case the best way is to use 0 to 100)

second step is to set a filter on this and map all values directly in cantabile.

    0-33     to 10%

33 - 66     to 20%

66 -100    to 40%

normal slider position then is in the mid

...nice .....works as expected

now I can directly half or double the individual effect-speed for each songstate

....I love this variety of possibilities
