Changing the start point of the samples on reverse playback mode by code

[Gabriel Strozi]

Hey guys,
I'm working in a metal instrument sampler and I have a question. But before the question, I need to explain some points:

• Because it's a percussive instrument, the samples has different lengths (I cutted each sample differentle depending on the duration of each recording);

• I created a button that allows user choose the playback setting between Normal, One shot, Reverse and Reverse One Shot;

• If the user set Reverse One Shot, the transient of the sound will comes up in a different moment, because each sample has different legths, so the duration of the fade-in (in the reverse reproduction) will be different, right?

Ok. The solution is: if the user set Reverse One Shot, I want to set the same length for each sample played. Doing this I'll be able to garantee that ever transient will comes up in regular time, making the reverse feature much more useful.

After all this, how can I control the length and the starting point of each sample by code? Any suggestions?

Thanks in advance!

@Gabriel-Strozi the start point can be modulated:

Give me a sec and I'll try and make a snippet for the sample length

Hmmm, really cool! I'll play with this setting!

Ok, thank you so much! By the way, I never imported a snippet. I need to open a new project for that?

@Gabriel-Strozi to import a snippet go to File, Import Snippet.

So, ignore the sample start modulation that I mentioned before. If that is actve it means that you can't move the Sample End point where you want to. In this snippet the sample start knob works ok but the sample end knob just makes the end point decrease, which ever way yo turn the knob. So it needs more work / someone better at HISE than me to come in and fix it

But this should be a good jumping off point....

[Gabriel Strozi]

Nice!! Importing the snippet right now. I'll try to understand and develop from there! Thank you so much!

[Gabriel Strozi]

I tried a bit to use this SampleStart feature, but when the playback is set to reverse, this parameter works in a strage way.

I will explore more.

[DanH]

@Gabriel-Strozi maybe it's better to make new samples of the reverse drums. This way you have more control. When the user clicks 'reverse' the sampler could change sample map, or perhaps have two samplers and switch between them

[Lindon]

@DanH or add different amounts of silence to the shorter samples to make all samples the same length

[Gabriel Strozi]

I got. The problem is that I already have a User Preset working like Mr. Healey techs, using combobox to change sample maps. To make another samplemap exchange system, would be really hard to me to understand how! I need to think about it and about how big the change on the code would be.

[Gabriel Strozi]

Actually, I'm struggling right now to simple change between Normal, One Shot, Reversed and Reverse One Shot. It seems to miss an attribute for that. It's possible to change between this settings by code?

[d.healey]

Use a different sampler and sample map for the reverse mode, then you can cut the samples exactly how you need them.

I'll try it! And how can I switch between Normal and One Shot playback? I'm trying to use

Sampler1.setAttribute("OneShot", value);

But don't work. Any suggestions?

[d.healey]

@Gabriel-Strozi Try Sampler1.setAttribute(Sampler1.OneShot, value)

[Gabriel Strozi]

@d-healey said in Changing the start point of the samples on reverse playback mode by code:

@Gabriel-Strozi Try Sampler1.setAttribute(Sampler1.OneShot, value)

Also didn't work. Nothing changes

[d.healey]

@Gabriel-Strozi You need to get the sampler as a child synth.

[Gabriel Strozi]

It worked! Now I just have to cut the samples and create new SampleMaps for the reverse Sampler.

Thank you so much!

[d.healey]

@Gabriel-Strozi Don't cut the samples. Just duplicate your sample map and rename it, then shift the start and end times inside HISE. That way you won't have to use extra disk space or RAM as it will share the same samples.

[DabDab]

@d-healey How do I use both Sample Start End Knob and OneShot/Normal button?
If I use const var Sampler1 = Synth.getChildSynth("Sampler1");

Start End Sample and Samplemap CB Not working..

If I use const var Sampler1 = Synth.getSampler("Sampler1");

Normal/Oneshot not working.... How to compensate both scenarios?

[ulrik]

@DabDab name them with other names

const var SSynth = Synth.getChildSynth("Sampler1");

const var SSampler = Synth.getSampler("Sampler1");

[DabDab]

@ulrik Ok.. got the logic.. :) (y) Thank you.
