VST issue // How to debug LMMS 1.1.3 Windows 64bits ?

[musikbear]

So any idea from you musikbear is welcomed :)

No. im pretty stumped on this one. If its not just 'out of ram', then its really suspect that this happens almost at same number of loaded vsts.

I would though make some experiments, in that respect -f.i. How is the situation id you
try to load :

* 15 instances of a well known working 64bit VST, and then load a 32 bit VST
* 30 instances of a well known working 64bit VST, and then load a 32 bit VST
* 45 instances of a well known working 64bit VST, and then load a 32 bit VST
* 49 instances of a well known working 64bit VST, and then load a 32 bit VST

in order to establish When does the issue kick in, but mostly, im stumped

Very weird...
So, I did your test :
VST 64bits (well know) : Camel Crusher
VST 32bits(Bigkixdippa or T-Force Alpha Plus or any 32 bits VST)

15+1 OK
30+1 OK
45+1 OK
60+1 OK

62+1 caused the problem..
RAM used 50%... (4GB/8GB)
CPU used 10%

Could you try to reproduce the bug on your computer please ?

Thanks by advance !

I cant use 64b at all :)

But you gave new info now.
The vst's are effect-vsts!
That could be important.

And one more important thing. Upstream you wrote:

I bought 4Gb more of RAM

So you recently expanded your ram?
Have you done tests on that ram?
Does it all register at bootup?

Oh I didn't know You have a 32bits !
Both VST Effects/ VSTi (i.e synth1)
Now I have 8Gb, Windows recognize it because with 4Gb and my biggest project : 90% RAM used
Now with 8Gb : 50% RAM used
So how to test my RAM ?
Windows whe'n I do ctrl+shift+ESC shows 8gb RAM

This issue is a real pain for me I love LMMS so I'm sad anything can't be done

Ok! Also important.

Then its propl. fine. But, You can test your ram with Windows Memory Diagnostic tool
* Save all and close all programs.
* Press Windows Key + R, type “mdsched.exe” into dialog that appears
* press Enter.
* choose first of the two options
During the hot-boot, the ram will be checked for errors
