kxmixer.exe is 158k,more less than old version,is that the result of optimized?

**dj_stick** · Dec 21, 2004, 03:23 AM

better compression/optimization of the mixer app

AMD Althon XP 1600+ & 512Mb
XP sp2
steinberg nuendo 2
m0,m2,m3 works fine
m1,m4,m5 freeze about 10 seconds

nyquility · Dec 21, 2004, 11:17 AM

After getting constant freezes with 3538g Asio and switching back to 3537 heres my first quick test of Asio under 3538h.

CPU: Athlon XP 2800+
RAM: 1024 MB DDR
Soundcard: Audigy 2 ZS
OS: XP SP2
Asio used for testing: foobar2k with asio output plugin

Format: 16/44Khz (16+0)

Quick Sync Method Test:
m0: No freezes
m1: 10+ second freezes/unusable
m2: No freezes
m3: No freezes
m4: 10+ second freezes/unusable
m5: 10+ second freezes/unusable

Latency tests:
m0 2.90ms (128 samples): Strong/Frequent Pops and Clicks
m0 4.35ms (192 samples): Few/Infrequent Pops and Clicks
m0 5.80ms (256 samples): Few/Infrequent Pops and Clicks
m0 8.71ms (384 samples): Few/Infrequent Pops and Clicks
m0 11.61ms (512 samples): No audible Pops and Clicks

m2 2.90ms (128 samples): Strong/Frequent Pops and Clicks
m2 4.35ms (192 samples): Few/Infrequent Pops and Clicks
m2 5.80ms (256 samples): Very Few/Rare Pops and Clicks
m2 8.71ms (384 samples): No Pops and Clicks

m3 1.45ms (64 samples): Audible Warping and Major Audio Slowdown
m3 2.18ms (96 samples): Few/Infrequent Pops and Clicks
m3 2.90ms (128 samples): Very Few/Rare Pops and Clicks
m3 4.35ms (192 samples): Very Few/Rare Pops and Clicks
m3 5.80ms (256 samples): Very Few/Rare Pops and Clicks
m3 8.71ms (256 samples): Very Few/Rare Pops and Clicks

m3 is weird for my perception at least. Sometimes it gives me a (very) tiny but percievable slowdown of the audio playback after a few seconds of playback at low latency values.. could just be my broken ears. Sometimes I get a rare artifact after playback starts then nothing further, usually after playback has run a while.

m0 default method gives me about the same results as I got with the 3537 drivers.

Decided to stick with m2 8.71ms at the moment.

Anyway I am in no way an ASIO expert and all these results are purely based on my perception when playing back the same audio file. Hope it still helps a little.

PS: Just noticed when previewing my post that I get a single pop when hitting the preview button (CPU under load?) when using m2 8.71ms

Going back to m0 11.61ms.

PPS: Thanks for all your work Eugene, fiddling with my kX drivers has become a major hobby for me and apart from beating the Creative drivers hands-down, I feel I have actually learnt quite a bit about computer audio just from learning to use your drivers. I'm so glad you've been able to renew your activity and put so much time into the 3538 drivers. Now I just have to fall on my knees and pray that Max M. gets round to recompiling, updating the UFX pack. I miss my Parametric EQ.

hi all,

3537 : usual setting 5.33ms for playing live
3538h (3538g was unusable), here are some results with cubaseSX2, playing live on The grand Vsti, all in 48kHz, 16+16 :

sync latency result
m0 5.33 ok
m0 4 some pops
m0 2.67 lot of pops
m0 2. distorsion

m1 5.33 freeze (almost hang)

m2 5.33 ok (high cpu load)
m2 4 ok (high cpu load)
m2 2.6 some pops (high cpu load)
m2 2 lot of pops (high cpu load)

m3 5.33 ok
m3 4 ok
m3 2.6 pops

m4 5.33 random latency (system shortly hangs?)

m5 5.33 freeze (almost hang)

For me it seems the best setting (and improvement) is m3 and 4ms
and as usual : great job and thks to the kx team !

EDIT : for big project playback, I switch back to m0 at 5.33ms (like in 3537)

ASIO...everybody talks only about this...gamers don't need that...when there will be EAX support ?
And what about this option in bass redirection that disable cutting off base from front/rear/center speakers and works only for sub ???
Everybody concentrate only on this f***** ASIO and forget about other improtant things

JohnMcClane · Dec 21, 2004, 03:12 PM

Calm down dude, I already explained it - there will not be EAX support. And your concerns about bass redirection can be achieved through plugIns, like I already mentioned.

Anyway, this drivers are NOT aimed for gamers, but for musicians, so don't complain about ASIO etc.

smasha · Dec 21, 2004, 04:06 PM

M0,M2 work best for my old 1 gig athlon tbird(512 mg sd 133 ram) at around 10 ms latency.

M3 have a few clicks here and there.

M1,M4 and M5 lag big time and are unusable on my old machine.

I'm happy with M0-10.67ms latency on an A2 Plat. Ex card.

Thanks Eugene.

Happy with these drivers ASIO performance.

fvi · Dec 21, 2004, 10:27 PM

(post #2)
with 3538h, I have BSOD saying :
"error in kx.sys - It seems that the driver reports a page area memory instead of a non page area memory"
Condition : Cubase is running or ran a big project (1.03Gb of memory load in windows task manager)
Action : trying to move main volume in the kx mixer

Never had that with 3537
Hope it helps

miguel · Dec 21, 2004, 11:21 PM

With 3538f 5ms without trouble and 2.66 with few glitches if the song gets complex, probably because 2.66ms takes 10% more cpu all by itself.

With both 3538g and 3538h I can get nowhere near that. m0, m2, and m3 behave better but at even 8ms I get crackles and sync errors from the sequencer every few seconds.

E-mu APS, Win XP, AMD thunderbird 900, 512 RAM, priority given to background processes (in case it matters).

Thanks Eugene for the efforts.

ASIO is important.
EAX is not important.
Please be more civil with your posting

EDIT: as for the bass re-direction, this is standard to most drivers, soundcards etc. You are in an uncommon situation. Btw doubling up on the bass output with the speakers AND the subwoofer could create adverse phasing effects, that would ruin the sound. But what you are trying ti do *might* be possible with some complex DSP routing

Chester01 · Dec 22, 2004, 03:21 AM

I know this sounds bad, but what can I use ASIO for, is it primarily for MIDI (thats what I have picked up on from reaidng posts and such.) Thanks!

**dj_stick** · Dec 22, 2004, 03:28 AM

its primarily used for low-latency audio recording

Chester01 · Dec 22, 2004, 03:34 AM

so is it off of a line in port? or is it inernal recording (synthesizer latency) I was never quite sure what the audio source was for ASIO...

ASIO latency affects both Line in (with software monitoring enabled in sequencer. Of course the DSP is very handy for "direct" monitoring which isnt affected by ASIO latency) and it also affects Software synths and Software effects. very low latencies allow for software monitoring WITH software effects in the host sequncer. Very low latencies also alow for the live playing of software synths from midi keyboards (I use kX powered PC onstage as a sound module)

Chester01 · Dec 22, 2004, 04:07 AM

ahh i get it now, thanks! ASIO is if you want software applied "dsp" or other effects... This clears things up nicely.

**dj_stick** · Dec 22, 2004, 04:09 AM

no, you can use DSP or software effects without ASIO, its just that ASIO is more efficient, faster, and has more possible inputs

Hi
I got a problem with the link:
www.kxproject.com/kx3538h.rar

When I right click and choose save as It shows a link to a file called 3538h.htm

When I doble click it opens an IE page with the good url : [color=#dddddd]kx3538h.rar but in html page

Strange

Am I the only one?
I tried 3 machines on my network and 2 Browsers IE & Netscape

May be someone could send it to me attached to a mail?

modes m0, m2, m3 work (the others hang). However I am not getting the 5.33 ms latency on my VST instruments on any configuraion with 3538 (ie 3537 is currently faster for me).

EAX is as important as ASIO, yet i agree on the fact that some people need to be less aggressive.

BTW does this 3538 driver allows the Sound Blaster Live 5.1 OEM versions (SB0220) to use 5.1 speakers or are we still forced to use 4.1 ?

nakamichi · Dec 23, 2004, 07:38 PM

At last...here's my

kX 3538h ASIO Performance Test
---------------------------------

System used : AMD AthlonXP 2200+,256MB DDR266,Audigy2 Retail SB0240,80GB 7200rpm,ATi Radeon 9100 64MB,screen resolution 2048x1536@66Hz,a pair of headphones,WinXP Pro SP1(heavily tweaked and optimized for performance)
Host Sequencer : FL Studio 5 + various external synths
SoftSynths used for "torture" : Sytrus (FM goodness),SoundFont player (sampler goodness),Yamaha S-YXG100 Plus(MIDI goodness),various analog synth plugins and finally,just for fun - all the BUZZ machines you can get from www.buzzmachines.com

ASIO mode used : 16/48 (2+2 outputs)
Songs used for benchmarking :
- "Juicy Dreams",my unfinished dance masterpiece,eating easily 100% CPU power at 10ms

- "Synth Power",another of my tracks,a great piece of music that doesn't eat as much CPU as the main benchmark track.

Test results:
-----------------

ASIO modes m1 and m5 (HT/SMP CPU Optimized Sync) - unuseable on an AMD Athlon XP CPU (these 2 modes are for Hyper-Threading Pentium 4 only)

ASIO mode m4 (Kernel Sync) - works 50% of the times,freezes 50% of the times,not stable,so - unuseable

ASIO mode m0 (Normal Sync) - 8ms - slowdown,pops and heavy distortion (X)
10ms - distortion and pops (X)
16ms - passed,OK no pops,crackle or distortion Peak CPU utilization = nearly 100%...lotsa juice in my track (O)
MINIMUM acceptable latency = 16ms

ASIO mode m3 (Timer-based Sync) - 5ms - distortion and pops (X)
8ms - passed,OK maybe one random pop ocassionally after every 10 minutes Peak CPU utilization = 100% (O)
MINIMUM useable latency = 8ms (what a big boost from the normal mode!)

ASIO mode m2 (Thread Sync) - This is the most insane mode I've experienced yet

It uses ALWAYS 100% CPU power,like an old Windows 95 program or the WinXP Command Prompt emulator,but gives RADICAL results.
I wonder if this mode keeps up the latency at a constant level,or it is variable? Hmmm...
The results are really insane! You'll see for yourself. I used another song of mine to test this mode,which uses much less CPU than the benchmarking song,and I found out something special with this mode:

Test Song #1: "Juicy Dreams"
5ms - crackles not many,but they make this setting unuseable.
*6ms - if there was a 6ms (6.something ms) setting,it should have passed easily. (O)
8ms - works like a rocket

(OO)
MINIMUM useable latency = somewhere in the middle between 6ms and 8ms
WARNING!!! - It uses 100% CPU all the time! Don't move your mouse or anything and disable everything graphical to get maximum performance!

Test song #2: "Synth Power"

10ms - works like a charm
8ms - solid as a rock
5ms - even better
2.6ms - sounds great
2ms - what? not a single pop? what is this? O_o
1.3ms - I've never,ever been able to play or hear a single note on any setting below 2ms before without getting creepy metallic distortion or backwards sound.Now,in this mode,it works without a glitch.what's going on?
1ms - I can't believe this! Rock-solid sound at 1ms on my machine without HyperThreading? Am I dreaming?
and finally (dum-dam-drum-bam!!) 0.6ms - it works.....perfectly....this is NUTS!
There is no lower latency than this to test,unfortunately,but I believe it could've gone even lower

Is this a BUG or is it really true that I got true 0.6ms latency on my PC?
Wow!

Now,some questions for Eugene:

Eugene,have you used any SSE,SSE2 or AMD-exclusive optimizations/instructions in these drivers?
Is your name Eugene or Evgeniy(since you're Russian)...just curious,really

Keep up your amazing work and best wishes for the New Year and orthodox Christmas.

nakamichi · Dec 23, 2004, 11:42 PM

More on mode 2:
------------------
I can now play a softsynth and get very high polyphony without a single pop at 2ms...it's like a dream....but I don't use this mode as default.Uses 100% CPU.You can't do anything else,because it causes sound glitches.
Good for playback,playing a softsynth and recording the stuff,but not for recording while having graphical peak meters for monitoring and turning knobs and changing parameters at the same time.

So,I use Timer-based mode as default for now.It's the best of both worlds.

Small Requests:
------------------
Also,if Eugene says he won't add keyboard navigation to the kX Mixer controls soon,it would be nice to only implement keyboard navigation in the ASIO Control Panel.For example,I can set the sync mode with the keyboard,but I can never set the Latency and the number of in/outs.

A keyboard shortcut for instant access to the kX ASIO Panel will also be good.(acess ASIO Control Panel everytime and in any situation with Ctrl+Alt+A or Mixer with Ctrl+Alt+M).

However I am not getting the 5.33 ms latency on my VST instruments on any configuraion with 3538 (ie 3537 is currently faster for me).

Test results: ----------------- ASIO modes m1 and m5 (HT/SMP CPU Optimized Sync) - unuseable on an AMD Athlon XP CPU (these 2 modes are for Hyper-Threading Pentium 4 only) ASIO mode m4 (Kernel Sync) - works 50% of the times,freezes 50% of the times,not stable,so - unuseable ASIO mode m0 (Normal Sync) - 8ms - slowdown,pops and heavy distortion (X) 10ms - distortion and pops (X) 16ms - passed,OK no pops,crackle or distortion Peak CPU utilization = nearly 100%...lotsa juice in my track (O) MINIMUM acceptable latency = 16ms ASIO mode m3 (Timer-based Sync) - 5ms - distortion and pops (X) 8ms - passed,OK maybe one random pop ocassionally after every 10 minutes Peak CPU utilization = 100% (O) MINIMUM useable latency = 8ms (what a big boost from the normal mode!) ASIO mode m2 (Thread Sync) - This is the most insane mode I've experienced yet It uses ALWAYS 100% CPU power,like an old Windows 95 program or the WinXP Command Prompt emulator,but gives RADICAL results. I wonder if this mode keeps up the latency at a constant level,or it is variable? Hmmm... The results are really insane! You'll see for yourself. I used another song of mine to test this mode,which uses much less CPU than the benchmarking song,and I found out something special with this mode: Test Song #1: "Juicy Dreams" 5ms - crackles not many,but they make this setting unuseable. *6ms - if there was a 6ms (6.something ms) setting,it should have passed easily. (O) 8ms - works like a rocket (OO) MINIMUM useable latency = somewhere in the middle between 6ms and 8ms WARNING!!! - It uses 100% CPU all the time! Don't move your mouse or anything and disable everything graphical to get maximum performance! Test song #2: "Synth Power" 10ms - works like a charm 8ms - solid as a rock 5ms - even better 2.6ms - sounds great 2ms - what? not a single pop? what is this? O_o 1.3ms - I've never,ever been able to play or hear a single note on any setting below 2ms before without getting creepy metallic distortion or backwards sound.Now,in this mode,it works without a glitch.what's going on? 1ms - I can't believe this! Rock-solid sound at 1ms on my machine without HyperThreading? Am I dreaming? and finally (dum-dam-drum-bam!!) 0.6ms - it works.....perfectly....this is NUTS! There is no lower latency than this to test,unfortunately,but I believe it could've gone even lower Is this a BUG or is it really true that I got true 0.6ms latency on my PC? Wow! Now,some questions for Eugene: Eugene,have you used any SSE,SSE2 or AMD-exclusive optimizations/instructions in these drivers? Is your name Eugene or Evgeniy(since you're Russian)...just curious,really Keep up your amazing work and best wishes for the New Year and orthodox Christmas.

nakamichi HardwareHeaven Lover Join Date: Oct 2004 Posts: 122 Rep Power: 0	More on mode 2: ------------------ I can now play a softsynth and get very high polyphony without a single pop at 2ms...it's like a dream....but I don't use this mode as default.Uses 100% CPU.You can't do anything else,because it causes sound glitches. Good for playback,playing a softsynth and recording the stuff,but not for recording while having graphical peak meters for monitoring and turning knobs and changing parameters at the same time. So,I use Timer-based mode as default for now.It's the best of both worlds. Small Requests: ------------------ Also,if Eugene says he won't add keyboard navigation to the kX Mixer controls soon,it would be nice to only implement keyboard navigation in the ASIO Control Panel.For example,I can set the sync mode with the keyboard,but I can never set the Latency and the number of in/outs. A keyboard shortcut for instant access to the kX ASIO Panel will also be good.(acess ASIO Control Panel everytime and in any situation with Ctrl+Alt+A or Mixer with Ctrl+Alt+M).
