General Midi library question

d.healey

Should I create 128 samplers in my project? Then how to change between them, which one is playing?

Definitely not.

When you load a preset it sets the value of the UI controls, so you have a control (can be hidden if you want) that changes the sample map. Then when you change presets it will trigger the control and the sample map will change.

I have a video on YouTube showing how to do this with a combo box, but you could use a knob.

I got it, however I constantly get the same error:

Your component reference is called cmbSampleMap not SampleMapList. It will make your life easier if you give the components the same name as the reference.

alfaholic

@d-healey Thanks.

As I can see one sample map can not be separated into groups, so for example to have a group for each drum family: Kicks, Snares, Hi Hats (monophonic group ) and so on.

Should I create 6 additional samplers for 6 drum families (Kicks, Snares, Hi Hats, Toms, Cymbals, Percussion) and then create separate sample maps for each of them, then change between them with the preset script as you already explained?

@alfaholic

There are a few different ways to map samples. Generally the main reason to use multiple samplers is to be able to apply different effects or modulation chains to different groups of samples.

If you don't need this then you can include all the samples in a single sample map. You can separate them using pitch, velocity, rr group, or a combination of these.

With your hi-hat you might also want to look into the choke script that's built in. I haven't used it but there are some threads on the forum discussing it.

@d-healey Thanks David, all clear.

I am not able to set the knob for pitch intensity. The knob is decimal, while pitch has 12 steps, is there a way to make it work?

d.healey

@alfaholic You can edit the knob's properties in the interface designer

alfaholic

@d-healey Sure, but I went through everything multiple times and still do not get it, this is why I am asking. Here is how it looks:

I tried everything, but the knob shows 0.5 while the pitch intensity shows 6 st.
If knob is set to min=0, max=12 then the intensity goes to million.

@alfaholic You have to change your min, max, mode, etc values to match what you're trying to do.

Like for what your are trying to do, it could look like this:

min: -12
max: 12
mode: linear
style: knob
stepSize: .01
middlePosition: 0
suffix: st

alfaholic

@trillbilly Sorry, I am an idiot.

Edit:

Or maybe not... :)

Yes, I forgot to put the negative value before, however nothing changes really as +12 goes up to 50 khz, also the scale is not the same as 0.83 on the knob moves the intensity slider to 9.96.

I see what you're trying to do now. You need to use a control callback for this instead of the processor/parameter ID method.

Is there a way to control all 3 bands in Parametric EQ with knobs?
I would like to have Lo Shelf, Peak, and High Shelf, also 6 more knobs for frequency and Q factor.

At the moment I am using 3 EQs, not sure how much more resources this uses.

Lindon

@alfaholic - so each node in your paremetric eq is displayed with a number - and you use this number thus(lets say we are talking about the first node(node zero);


const var EQ1 = Synth.getEffect("EQ1");  //assume our EQ is called EQ1


inline function onLoShelfFreqControl(component, value)
{
	//low shelf freq
	local eqdx = 0 * EQ1.BandOffset + EQ1.Freq; //get the index....
	EQ1.setAttribute(eqdx, value); // set its value
};

inline function onLoShelfGainControl(component, value)
{
	//low shelf Gain
	local eqdx = 0 * EQ1.BandOffset + EQ1.Gain;
	EQ1.setAttribute(eqdx, value);
};

Content.getComponent("LoShelfGain").setControlCallback(onLoShelfGainControl);



inline function onLoShelfQControl(component, value)
{
	//lo shelf q
	local eqdx = 0 * EQ1.BandOffset + EQ1.Q;
	EQ1.setAttribute(eqdx, value);
};

Content.getComponent("LoShelfQ").setControlCallback(onLoShelfQControl);

I just tried to use Choke Group Processor to make the Hi Hats and few percussion elements choke themselves, but as I can see it does not serve this purpose.

Do I need a script for this as well?
