plugin (and host - XT2 here too) dying on closing GUI - confirmed

dropdown menus SEEM (but see below) to be working OK here (ubuntu feisty) - is it an issue with all of them or just some ? - EDIT - ignore this - reread your post properly - bug confirmed

ive only heard about 3 notes out of the synth though because by that or point (or even before) its crashed taking the host with it after pressing play

MORE than grateful the linux version is developing too though

"is that dll supposed to make noise or is it just a tease"

i decided to use my own code rather than a cad application to design panel layouts for the hardware i'm going to be producing. it might make sounds a little later though since i'll want to test the layout and synth configuration before building the prototypes. when i do that it'll be based upon the code from xhip, b"asically a slightly modified stripped down version of xhip.

"ive only heard about 3 notes out of the synth though because by that or point"

hm, that isnt good news. i didnt bother to test the audio output. does the guiless version work ok? http://xhip.cjb.net/xhip/releases/v0/b6 ... .6.14.5.so

http://xhip.cjb.net/xhip/releases/v0/b6 ... .6.14.7.so
http://xhip.cjb.net/xhip/releases/v0/b6 ... 6.14.7.dll

- fixed the bugs, found more bugs and fixed them using valgrind on linux. (some core memory leaks got fixed! - influences the windows (all) version)
- yikes is linux energyxt full of bugs or what?
- added a couple waveforms while just playing around. if any of your patches used "staircase" in the oscillators while it was actually noise, sorry, i moved it to spaces down. this is just me fooling around, i'll probably remove these waveforms later. these are analog-divider waveforms, the pulse version doesnt have adjustable width although it is possible since there is no control for me to use. (pw gets used for division ratio)

tested, works good on linux. you got it to crash while playing audio? can you test this new version? my linux box doesnt have audio.

(fiddling with pw - division ratio)

what the hell is with that distortion.. i think the res compensation thing is too bright. having it disabled though seems to dim. i'll have to tweak that.

hm.. oh no the distortion is almost definitely due to the sync going into the divider oscillator. probably the detune goes below the fundamental there and a negative value gets sent to the blep generator.

still seeing the same thing - it loads up fine and all the GUI controls work (closing the GUI no longer crashes the plugin or the host) but the minute i try to get it to output audio it throws XT2 back to the desktop

i have no other linux VST host to check it in so no idea whether this is the plugin or XT2

any other linux XT2 users able to check this out ?

ill throw a post up over in the energyXT forum if thats OK ?

eerk
The latest version uses 45% cpu (for the preset "autopitchbend")

(and does not look for the default preset bank at start up : starts with blank sounds.

crash on producing audio confirmed, both eXT and Jost.
Jost also crashes on any GUI action

aciddose fm mode is subtle ?or maybe not working here?i can t hear,it does nothing here and can t find it in the to do list, maybe it s a bug i have or maybe i miss something ...

just tested, and can confirm this...although i had to do a bit of moving in jost before it crashed......thanks for linux development, will test more if needed

probably i'll just need to stick a soundcard in my linux pc and test this myself. it is very strange that it would crash when producing audio if the guiless version worked?

the only possibilities are:

1) something with the mutex (seems less likely now as i think it wasnt even being used. it is possible these crashes only occur with the gui open - but that seems unlikely.)
2) some bug exists that doesnt cause a problem when running on windows. this is likely since linux is a _lot_ more vulnerable to out-of-bounds access due to the way it allocates memory. (to my knowledge, all allocated blocks are padded and access locked to the parent process)

if you're referring to xmod, or oscillator fm, you must select the mode, and then adjust the depths on the oscillators page. (osc a/b "mod depth")

"The latest version uses 45% cpu (for the preset "autopitchbend") Shocked
(and does not look for the default preset bank at start up : starts with blank sounds."

absolutely nothing has changed in the audio code for the last ten releases. the preset "autopitchbend" uses the same amount of cpu as any other preset. if you experience 45% use for that preset, you should experience 45% use for all others as well. test with previous versions until you find a version which behaves differently, then let me know. \

"Jost also crashes on any GUI action"

yes... it does. back to debugging for me then.

weird.
Some presets use 3% cpu, some reach 45% cpu.
I always like that "autopitchbend" preset, so i think i would have noticed that before, as 45% for one note polyphony makes it unusable in a project without needing freeze.

... for the last ten releases.

Yes, maybe, but so many versions, so many changes, so many commas in the version number that i don't really know if it means the code hasn't changed since 2 weeks or since 1 year

ahhh thanks i was talking about osc fm mode

"Some presets use 3% cpu, some reach 45% cpu."

actually you're probably only seeing the average cpu use. try holding down the notes to get the same level of voice activity and you should see the same cpu regardless of the patch. if you see a different cpu use for different patches at that kind of level, it would be a severe bug. i'm absolutely sure that isnt happening though - some patches have a fast release.

voices only take up cpu while they're active. if they're silent, they do not run.

eidenk · Post by **eidenk** » Sat Sep 08, 2007 10:16 pm

The CPU use with one held note should be the same regardless of the settings of xhip ?

If this is what you mean it is not what I observe here as CPU use can go extremely high. So high that I would consider it unusable. The default preset uses about 2-3% but after a randomization or two it can get as high as 40-50%.

BTW my OS always ends up freezing if I play a bit too much with xhip in the Cantabile randomizer. I think Brad got in touch with you about it last year.

thats probably due to unison amongst other things.
