It seems when you send a clock/stepm count to parse an array position it starts to act a bit weird.

can anyone test for me?

thnx 

gktrk_1 fillarray 1, 2, 3, 4, 5
kstepinput chnget "stepvalue"
printk2 gktrk_1[kndx]

Is the clock always an integer? Or sometimes it's a float? Arrays will truncate a float index.

whoops i made my own bug in the example code (i modified it a little because of an array change) the code should be

gktrk_1 fillarray 1, 2, 3, 4, 5
kstepinput chnget "stepvalue"
printk2 gktrk_1[kstepinput]

i'm wondering if it's the clock sent that's causing bad behavior reading wrong values from arrays/mathematical bugs, or a timing error somewhere. .

so if you want to replicate my environment i am using remove the fillarray code since gktrk_1 is obviously initialized 

https://knobcore.github.io/tracker is a live coding environment with a sequencer i have been working on. in fact, i ironically decided to use javascript for clock generation because the ones you can make in csound doesn't seem too stable with time.

hello dear risto -

im not sure i understood what you need. because when you run csound it executes the instr only once. but i think you run csound several times from java (each time that midi happens in java). so perhaps you need to count how many times you run csound from java ? and write if-statement. 

but if you run csound only once you can count like this:

giCount init 0

instr 2

giCount += 1

endin

but again, i dont think you need it if you run csound for once.

hope that helps, if not explain more please -

Hello all !

This might be a stupid question related to performance threads (java, maybe python also ...),

but how can I give an i-message according to the following principle:

pt.InputMessage("i2 0 0"); // pt is the performance thread

I try to activate the second (help) instrument in an orchestra as soon as csound gets the message from java (the first 0) and it would be executed only once (the second 0).

As far as I understand the second argument should tell the relative time from the start-time.

When this application in question works in real-time, the relative time is not known.

I guessed that maybe 0 would work in real-time case to indicate the present time.

The last argument gives the duration time in beats, but how to execute that instrument only once?

Again here I guessed that maybe 0 would give the minimum duration (one round) for the instrument execution, but looks like it doesn't work that way.

The reason why I ask this is that I'm trying to send a message from java to csound when some midi-values have been already read into java and that way release csound to read further midi-input values. The instrument 2 simply sets only one help-variable to a certain value.

Any ideas ? Thanks in advance !

pp is a wrapper around the array, the API function take a pointer instead. Look at cs_glue.hpp to see how to get it.

I tried to get an answer from HI (human intelligence) how to use ScoreEvent-method but

because of poor success I turned to NHI (non-human intelligence) in this case Edge-Copilot.

1) I asked the following question:

 "can you find any example of java-code using csound-api ScoreEvent method?"

 And this was the answer:

import csnd6.csnd6;
import csnd6.Csound;
import csnd6.CsoundMYFLTArray;

public class CsoundExample {
    public static void main(String[] args) {
        csnd6.csoundInitialize(csnd6.CSOUNDINIT_NO_ATEXIT);

        Csound csound = new Csound();
        csound.CompileOrc("instr 1\n a1 oscil p4, p5, 1\n out a1\n endin");
        csound.ReadScore("i1 0 1 0.5 440");

        csound.Start();
        csound.PerformKsmps();

        // Create a score event
        CsoundMYFLTArray pFields = new CsoundMYFLTArray(5);
        pFields.SetValue(0, 'i');
        pFields.SetValue(1, 1);
        pFields.SetValue(2, 0);
        pFields.SetValue(3, 1);
        pFields.SetValue(4, 0.5);
        pFields.SetValue(5, 440);

        csound.ScoreEvent('i', pFields, 6);

        csound.PerformKsmps();
        csound.Stop();
        csound.Cleanup();
    }
}

That looks actually quite clear, but it is related to Csound-type object.

2) So asked another question:

"can you find any example of java-code using csound-api ScoreEvent method in the case of Performance thread ?"

Now the answer was this:

import csnd6.csnd6;
import csnd6.Csound;
import csnd6.CsoundPerformanceThread;
import csnd6.CsoundMYFLTArray;

public class CsoundPerformanceThreadExample {
    public static void main(String[] args) {
        csnd6.csoundInitialize(csnd6.CSOUNDINIT_NO_ATEXIT);

        Csound csound = new Csound();
        csound.CompileOrc("instr 1\n a1 oscil p4, p5, 1\n out a1\n endin");
        csound.ReadScore("i1 0 1 0.5 440");

        CsoundPerformanceThread perfThread = new CsoundPerformanceThread(csound);
        perfThread.Play();

        // Create a score event
        CsoundMYFLTArray pFields = new CsoundMYFLTArray(5);
        pFields.SetValue(0, 'i');
        pFields.SetValue(1, 1);
        pFields.SetValue(2, 0);
        pFields.SetValue(3, 1);
        pFields.SetValue(4, 0.5);
        pFields.SetValue(5, 440);

        perfThread.ScoreEvent('i', pFields, 6);

        // Wait for the performance to finish
        perfThread.Join();
        csound.Cleanup();
    }
}

The actual syntax of the ScoreEvent-call seems to be the same in both cases.

It looks like Copilot gives here a wrong answer because there should be one additional

parameter in the call in the Performance-case.

Of course I tried both cases in java-code but without success.

I can define those p-field arrays but the problem is the actual method call.

When I try to utilise CsoundMYFLTArray-type parameter in the code:

CsoundMYFLTArray pp = new CsoundMYFLTArray(3);

pp.SetValue(0, 2);

pp.SetValue(1, 0);

pp.SetValue(2, 3);

And then use the actual call like this (c is of type Csound):

c.ScoreEvent('i', pp, 3 );

Now i get this error-message in Eclipse:

"The method ScoreEvent(char, SWIGTYPE_p_double, int) in the type Csound is not applicable

for the arguments (char, CsoundMYFLTArray, int)"

This clearly indicates that for some reason the definition in the API for the ScoreEvent is

somehow wrong. Copilot suggested Csound MYFLTArray, but it has been defined as SWIGTYPE_p_double in csnd6.jar.

I can't understand how any kind of test could have passed java-compiler if tihs method

had been used in java-code.

There is still one question mark here, the value 3. Is it correct in .GetPtr(3)  (= number of elements) or should it

"point" to the fist element of the pp array ?

c) Any idea why Edge-Copilot could not give a correct example here ? Maybe this type of NHI is

not intelligent enough :-)

Do you mean https://csound.com/docs/api/interfaces.html or what ? (this doesn't exist)

 At the main page https://csound.com/docs/api/index.html there is the following text:

"The Csound Application Programming Interface (API) reference is contained herein. The Csound API actually consists of several APIs:

• The basic Csound C API. Include csound.h and link with libcsound.a. This also includes the Cscore API (see below).
• The basic Csound C++ API. Include csound.hpp and link with libcsound.a.
• The interfaces API, includes a number of auxiliary C++ classes, which add functionality and support the wrapping of the Csound API by various languages (e.g. Python, Java, Lua)."

Unfortunately only the first two items have a link forward, but the "interfaces API" doesn't have any.

I'm a bit confused where to go now ?

Well, learning how to use git is a good idea since it’s ubiquitous, and checking out the sources is not that much of an effort and it doesn’t take too much space
either.

Alternatively, you can look at the file online, https://github.com/csound/csound/blob/csound6/interfaces/cs_glue.hpp

Or you can do neither of these things, it’s up to you. You asked for help and I am suggesting where you could search for it.

Your problem is not with ScoreEvent, it is because you are not using CsoundMYFLTArray correctly. This is
in cs_glue.hpp.

The API is written in C and this is the reference

 

https://csound.com/docs/api/index.html

There is a thin C++ wrapper to these functions

https://github.com/csound/csound/blob/csound6/include/csound.hpp

There are Java bindings to the C/C++ API generated by SWIG. Since Java cannot deal with things like pointers and callbacks, there is extra code to wrap these in cs_glue.hpp/cpp. These are not part of the API and are not documented beyond the comments in the header file. 

The problem I pointed out in the code you asked about is that you were not using the wrapper class correctly. This was indicated by the error message

If you look at the header file you should be able to see what you need to make it work. If you want to know the parameters for csoundScoreEvent() you look at the API reference. The types reported in Eclipse are SWIG-created to accommodate the bindings,

and if there are C pointers involved as in this case, you will need to use the wrapper.

CsoundMYFLTArray::GetPtr(int index) is probably what you need, but don't take my word for it, check the header files.

Aside from this, a look at Java examples in the CsoundAPIExamples repository seems to indicate that using ReadScore() is preferred to using ScoreEvent() in Java. Possibly because of the extra complication of using arrays/pointers.

I don't know if you noticed but i wrote e.g. ScoreEvent.

The comment was a general one for all java-methods.

I can see the type of each argument of any method in Eclipse,

but what is the purpose of each argument ?

Even the names of the arguments could help to me guess what

and where to put which values.

--Risto

P.S. Concerning this specific argument I suppose that

I need to use index value 0 to point in the first element of the array

in order to get the correct pointer value.

Your problem is not with ScoreEvent, it is because you are not using CsoundMYFLTArray correctly. This is
in cs_glue.hpp.
