Hello Martin,

I've donwloaded and unpacked this SDK V2, and I'm very desappointed 'cause I cann't open any solution with my version of Visual C++ Express (the free one )!

cheers

hi vincent,

It's very strange, I've made the SDK V2 on VC++ Express, exactly on this version :

.

what kind of message VC Express bring you ?

Vincent · Unread post by **Vincent** » 02 Jan 2009, 18:10

OK!!!!
Not strange at all!
I don't know how I did this, but I run a Visual C++ 2005!
Tell me pleazzze: where did you dwnload this C++ 2008?!
Thanks and sorry for this stupid post!
I'm impatient to start!

cheers

Hello Yan,

Thanks for the link. Google doesn't like me and makes some jokes I don't appreciate!
I had to know that there was a 2008 edition and ask for it...
Now, let's go!

'Not coder', exactly. I'll talk, don't worry!

Vincent · Unread post by **Vincent** » 03 Jan 2009, 00:07

Evrything works fine now.
Thanks Yan for the right link.

I had a look in the user modules.
Looks simple, but unfortunately for me, all what I know in coding is in Visual Basic (VB 2008 is nice!).
With Visual C++, I have to spend some time to re-learn...
And time, you know...
Yeah, I'll take it, every day.

cheers

martignasse · Unread post by **martignasse** » 03 Jan 2009, 00:47

Even if it's not directly related to Usine,
i'll try to put some links to CPP basics on the WIKI, as it can help to understand the syntaxe, and how to manipulate data.

Can't promise you 'll become a master, but you should arrive to make some user module pretty easly.

A+

Vincent · Unread post by **Vincent** » 03 Jan 2009, 03:45

Thanks, Martin.
Yes, I think I'll be able to have some good time!
Anyway, I won't make modules just as a game, I think that when I'll have do what I need, I'll comme back to Usine.

cheers

Bouh...
C++ give me headaches. I understand absolutely nothing, it seems *very* different from VB that I now know a little...
Architecture is different, concepts are different, ways of conception and ways to build... I'm just lost.
And the MSDN in this release is so poor! 2/3 help files are missing. I've tryed to download the whole ISO stuff, but download is bugged here. Maybe with Firefox... I'll try.
Could you please give me a couple of links toward efficient french tutos for newbleubite?

I had a clear project for a sync module, I think it will wait a while. But when I'll be somewhat ready, i'll come back for tons of questions!

Thanks for this SDK, Martin, it is really a good stuff.

cheers

Quick answer :

Apprenez à programmer en C++ !

they are french tutorials from 'le site du zero' so, especially for 'newbleubite'

.

C++ is built on top of C language, so it's recommended to read the C one before, has it speak about very basic and important things to understand C++.

PS : I'll add those links on the WIKI when i'll make the french pages.

Hope it help

Thanks,

martignasse · Unread post by **martignasse** » 27 Jan 2009, 13:11

Hi antwan,

Normally, all projects should build without errors, in release and debug mode...

But the fact is, there are some inconsistence in projects properties between release and debug configs.
So, will go for a V2b update shortly...

In the mean time, i can explain what is wrong to let you play with the SDK

for the DrawPad | Debug :

1>c:audiousine sdkcppusine cpp sdk v2auserdrawpadexampleusedrawpad.cpp(300) : error C2664: 'DrawTextW' : cannot convert parameter 2 from 'LPSTR' to 'LPCWSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>Build log was saved at "file://c:audioUsine SDKCPPUsine CPP SDK V2aUserDrawPadExampleDebugBuildLog.htm"
1>UserDrawPadExample - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

In Project properties(Debug), you have to change the Configuration Properties->Ceneral->Character Set to No Set instead of Unicode, which cause this invalid cast.

For the ModuleTemplate | Debug :

1>LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library
1>libcpmtd.lib(xdebug.obj) : error LNK2019: unresolved external symbol __malloc_dbg referenced in function "void * __cdecl operator new(unsigned int,struct std::_DebugHeapTag_t const &,char *,int)" (??2@YAPAXIABU_DebugHeapTag_t@std@@PADH@Z)
1>libcpmtd.lib(xdebug.obj) : error LNK2019: unresolved external symbol __free_dbg referenced in function "void __cdecl operator delete(void *,struct std::_DebugHeapTag_t const &,char *,int)" (??3@YAXPAXABU_DebugHeapTag_t@std@@PADH@Z)
1>C:audioUsine SDKCPPUsine CPP SDK V2abinTemplateModuleCPP_D.usr : fatal error LNK1120: 2 unresolved externals
1>Build log was saved at "file://c:audioUsine SDKCPPUsine CPP SDK V2aTemplateProjectDebugBuildLog.htm"
1>TemplateModule - 3 error(s), 3 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

In Project properties(Debug), you have to change the Configuration Properties->C/C++->Runtime Library to Multi-threaded Debug (/MTd) instead of Multi-threaded (/MT), which cause this libs conflict.

Note that the ModuleTemplate is here as a base to make new project easier, even if it should build out of the box, it miss some important code to be functional. You have to add at least what mentioned in code comments.

The best solution would be to make a VC wizard for new user module... if someone can do that, it will be perfect

Anyway, thanks a lot for the feedback, and sorry for these troubles, i haven't test enough before release :/

Thanks for the clarification. That'll get me started. Though I'm still a bit scared of it all

antwan · Unread post by **antwan** » 27 Jan 2009, 23:56

Hello once again,

Okay, so I got these things to compile okay.
But how do I actually get from compiling/building to having an actual module in usine? I can't find any usr-file etc. created as a result of the release-build.

Cheers,

antwan

martignasse · Unread post by **martignasse** » 28 Jan 2009, 10:32

hi,

Normally, the result of compilation for all projects are in the bin folder, named like the project and with a '_D' for debug version and a '.usr' extension.

If it's not the case, you have to check in the project properties (for Release and Debug mode) Configuration Properties->General->Output Directory it should be $(SolutionDir)bin. If it's something else, follow the path to find the file.

Those files should be copied or moved in the Usine folder installFilesModulesUser to be visible in the Usine Browser->Modules->User and usable.

Let me know if you get it right.

antwan · Unread post by **antwan** » 28 Jan 2009, 10:41

Ah, of course the bin-folder! Found it.
Sorry I was looking in the ProjectDir/Release-folder... Silly me.

All good. Thanks,

antwan

martignasse · Unread post by **martignasse** » 28 Jan 2009, 11:06

no problems,

The Release and Debug folders of each projects are user for intermediates files in the compilation process (and there a few...).

I decided to 'centralize' the place where to found finales files.... in a bin folder. It will be more praticable when you'll have tones of users modules projects

Have fun

Gizzeta · Unread post by **Gizzeta** » 04 Mar 2009, 10:43

hallo!

thanks for the c++ SDK.
Is there a way to create or communicate with an audio buffer?

thanks

martignasse · Unread post by **martignasse** » 05 Mar 2009, 08:51

Hi gizzeta,

What do you mean by audio buffer ?

If you make an audio input parameter in your module, you have access to his audio blocks as usine inject them in the module.
(assuming there is an effective connexion with some audio flux)

Also, you can create some audio blocks inside your module and put them in an audio output parameter too.

The related structure in the SDK is TEVT, which contain the event data of your parameter.

In fact, i believe the SDK work quite similar as the VST SDK V2.4.

Hope it help

Gizzeta · Unread post by **Gizzeta** » 06 Mar 2009, 12:56

Hi Martin,

I come from MaxMSP and within it there is a buffer object to store sounds or big datas.I can acces it from the C++ module programming.
In Usine, if I need to store for examle a 60 seconds incoming sound inside my module, have I to do a memory allocation myself?
Or there's a function to acces at, to create a 4Mb buffer?

thanks

YouTube · Unread post by **senso** » 08 Mar 2009, 09:40

you have to manage memory yourself:
allocate in the create procedure and free it in the 'destroy'

Gizzeta · Unread post by **Gizzeta** » 08 Mar 2009, 13:16

i'll try, thanks!

Gizzeta · Unread post by **Gizzeta** » 09 Mar 2009, 11:01

hem....what kind of allocation?
an array of 7.000.000 floats elements? Or there's something better?

YouTube · Unread post by **senso** » 09 Mar 2009, 15:24

yes, it a good starting point to create an array of float; it's the easiest way.

you also have the possibility to allocate a PCHAR pointer (7.000.000 x sizeof(float)) and deal with pointers, often more efficient.

but allocating such a buffer can take a long time so don't do that in the main 'audio proceed' function.
try to do that in
- during the creation procedure
- the callback procedure

Gizzeta · Unread post by **Gizzeta** » 10 Mar 2009, 18:52

ok, thank you

and is there a function to print from an user module on the Usine console? (for debugging purpose...)

YouTube · Unread post by **senso** » 10 Mar 2009, 19:05

Actually no way, except to create a text outlet and connect it to a 'trace' module
It's a good suggestion I'll try to add this fuction as soon as possible.
Also Usine contains around 350.000 lines of reusable code. Maybe I could start to find a way to have an access to those functions.
For example reading audio samples from the hard disk, midi tools, etc.

hello
martignasse , in the CPPQuickStartEN.pdf and in french version too, you say :

"The last thing to do is to replace, in these two files, the world TemplateProject by
the name of your module (be sure to uncheck the Match case and Match whole
word options to replace all occurences)."

but i can't find the word "TemplateProject" in this two files, do you rather mean the word "TemplateModule" is to changed
with the project name ?

thanks

Yes, you are totally right it's "TemplateModule" that should be replaced by "MyModule" or what ever.

Excuse me for the typo, i'll correct this for the next release.

hello
correct me if i am wrong, in your example you use win api to code the graphical part of your draw pad.
i have read the two tutorial about c and c++ on le site du zero and i am not able to understand correctly your code.
is a tutorial like http://www.siteduzero.com/tutoriel-3-87 ... ndows.html pertinent for a good undertanding ?
if you are thinking to others ressources...

i try to add some an new output (data, midi or anything else) on a patch inspired by drawpad and prototype example.
compilation works but when a put my .usr file into usine, i can't connect it to others modules.
i suppose that i did a mistake but i don't find where
i add some line code in :
- get param info method (i add a new case)
-set event adress (new case too)
- i changed the number of params in get module info and try to change the value of pModuleInfo->ModuleType
anyone no what is to change to add output or have others sources codes available to see how they works ?

thanks

martignasse · Unread post by **martignasse** » 23 Mar 2009, 19:59

pansoul wrote:in your example you use win api to code the graphical part of your draw pad.

Partialy right, in fact, the 'simplest' way to code the graphical part is to use the GDI or the GDI+ (who are really little part of the Windows API), has they are used by Usine itself.

The difference between those is that GDI+ has OOP interface, and has more polished graphical result, but is slower than GDI, who is typical C interface.

The UserDrawPad example use the GDI library.

The link you provided seems to generic about the whole Windos API, here some specific resources for GDI and GDI+ :

MSDN for GDI+
MSDN for GDI
(added to the wiki)

You'll find a lot of tutorials with google for GDI+, less for GDI, don't hesitate to add them to the wiki.

as a note, you have to know that in theory, it's possible to draw the graphical part with DirextX or OpenGL, it's just that no one have made it for now. I even wanted to make test for vector graphic with SVG or OpenVG....but really no time for that theses days.

Hope it help

Seems ok, but did you add the corresponding TEVT* pointer in the include file ?

Code: Select all

// DrawPad class
class TDrawPad &#58; public TUserModule
&#123;

public&#58;

	TEVT*				pButtonClear;	// ClearButton Event pointer
	TEVT*				pPointsCount;	// PointsCount Event pointer
	TEVT*				pMyNewOutput;     // <----------------HERE

If it's not that, source code is needed to find what's wrong

Well, after testing, it seems like the text field param is always shown as inlet, whatever the IsInput/IsOutput values, which is anormal. I have to see with senso.
As a workaround for now, you can always extend the module in usine (the little white square in topleft) to access the outlet part.

Ok so,

I have the solution (directly from the boss

)

the text data is stored in the DATA array, one char per float !

so the way you have to code your text is a bit tricky....you need to cast each char as float per DATA array element.

for example (tested OK), assuming 'PTextTest' is your textfiel param:

Code: Select all

	char test&#91;&#93; = "hello";
	for &#40;i = 0; i < 5; i++&#41; &#123;
		pPrototype->PTextTest->DATA&#91;i&#93; = &#40;float&#41;test&#91;i&#93;;
	&#125;
	pPrototype->PTextTest->len = 5;

I'll surely make an helper function for future release...

Hope it help

I create a module that fill a buffer with a waveform stored in an external file and read it as a loop (oscillator).

it works nice, but when I add a second instance of the same module (even if not connected) it affect the output of the first module (it sounds like a frequency modulation). WHY???

Normally all the variables and pointers are internals to every instance of the module(private)...or not?

No, it's not exposed on SDK level.

For what use do you need this ?
