getTableValue and samplers crossfade issue

[andrei s]

Hello!
I want to make a crossfade knob for controlling few samplers gain using tables but there is some issue with getTableValue. It only send values 0 and 1, so sampler gains have only -100 dB or 0 dB gain values.

I find that in older version of Hise this code works as it should be, but in newest it works with this bug. Hope it's my code bug)
How can i solve it?

@problema can you not simply scale your output as required?

Console.print("value: " + ((value * 100)-100));

you get your table value out of

local gainValue1 = CrossfadeTable1.getTableValue((value));

so your call back

 local gainValue1 = CrossfadeTable1.getTableValue((value));
 Console.print("Gain value:" + gainValue1);
 Console.print("value: " + ((gainValue1 * 100)-100));
 SimpleGain1.setAttribute(SimpleGain1.Gain, ((gainValue1 * 100)-100) );

[andrei s]

@Lindon thank you for your answer, but i couldn't make it work.

local gainValue1 = CrossfadeTable1.getTableValue((value));

The issue here is gainValue1 has only 0 and 1 values, so the result would be 0 or - 100, or am i missing something?

SimpleGain1.setAttribute(SimpleGain1.Gain, ((gainValue1 * 100)-100) );

Here is a pic of my result with code from starting snipet

[d.healey]

There's a function for this something like Engine.getDecibelsForGainFactor

[andrei s]

@d-healey thanks for answer.

I already use Engine.getDecibelsForGainFactor

inline function onknbMixControl(component, value)
{
 local gainValue1 = CrossfadeTable1.getTableValue((value));
 local gainValue2 = CrossfadeTable2.getTableValue(value * 127.0);

 local dbValue1 = Engine.getDecibelsForGainFactor(gainValue1);
 local dbValue2 = Engine.getDecibelsForGainFactor(gainValue2);

 SimpleGain1.setAttribute(0, dbValue1);
 SimpleGain2.setAttribute(0, dbValue2);

Because gainValue has only 0 or 1 value, dbValue is 0 or -100, but i need smooth gain changing.

Why gainValue has only 2 values and how can i change that?

[d.healey]

@problema What is the end goal? I might have some suggestions.

[andrei s]

@d-healey the end goal is a crossfade slider between few samplers with ability to control the behavior of gain value changes with tables.

[d.healey]

@problema But why do you want to crossfade between samplers? Is it for crossfading dynamics? Is there a reason you can't use a single sampler and crossfade the groups?

By the way I made a video years ago about crossfading dynamic layers using a few techniques that might be of interest to you.

@problema why multiply the table values by 127 ? The values goes from 0 to 1 (displayed as 0% to 100%), so just remove that and it works just as expected :

@d-healey wow! It works and it's so simple and don't needs any scripting.
