Hi all

i just purchased sd3 and as usual latency is key. ive spend a few days reading all about it just about everywhere....

im looking to upgrade some hardware maybe, it can be done cheap depending on the requirements for recording etc...or very expensive.
this is the main reason for this Thread.

my personal goal is not to have UBER recording facillities, i just want to play drums with minimal latency, but all UBER hardware freaks are most welcome to post latencies.
lets all compare.. 🙂

my rig is a heavy overclocked watercooled quadcore 3570k cpu, with onboard realtek audio and 12 gigs of heavy overclocked ram.....using asio4all.
the bus is also overclocked so basically the realtek chip is also overclocked.
latency monitoring of all drivers yields no more then max 0,1ms and 0,2ms for nvidia kernel.
looking at the midi input its a roland mk2, and i play on a td12 module. the latency on usb I/O is no more then 0,1ms according to latency monitoring,
the realtek audiodriver has a latency of > 0,01ms

i can get 4,6ms output latency in SD3 with 128 samples and 1ms wave offset. 96 samples and crackling starts...

p.s i had to hack superior drummer via reg settings to use these values....seems the program has some internal test when asio settings are pushed back into sd3 after asio4all edit?
anyways it works with no problems with the reg hack and 4,6ms.....but i want less latency......always on the hunt for less. 🙂

so what can be done?. usb and firewire TB etc ,,,,are all external interfaces....they can never be as good as a chip onboard on the bus or pci express.
options:
1. my rig is from 2012 about and maybe just getting the latest cpu and MB with onboard sound will do for another 1-2ms reduction. however my cpu utilizations when playing is not even 15%, still the onboard soundcard is probably not the best... its a hd realtek. but the quality in the sound is great.
The low cpu usage (12%) when playing a track in sd3, leads me to think that bus speed and all transport layers are key....not so much a new cpu....its the new chipsets and sound chips... if anything.

2. bite the apple and get a RME pci express interface. but i dont need 20 channels and 90% of what u get for 800 bucks. i just need speed and sound. and maybe a highspeed midi interface include.

3 maybe try another mid end pci express

if you have a latency for youre setup please post what hardware youre using. 🙂 it will save all of us the hazzle of trial and error.
thanks in advance.

update: i did try a presoneus usb interface a couple of years ago...and as logic dictates, its never gonna give more then 6ms output latency. i returned it. the sounds was nice though. 🙂

small update:
the gamer community is kicking the latency doors due to E gaming , you want to hear the enemy before before you see him.
i ordered a intel 8600k z370 setup...the latest gear. i needed an upgrade anyways....

the gaming industry is moving forward,,, allthough its not a RME card for sure..... 🙂

i ordered the gaming pro msi board which comes with 2 realtek 1220 sound chips... one for rear speaker and one for front. spookey setup ive never seen before...focus is lag and quality....
its located on a shielded circuit , got a headphone amplifier , seperate pcb layers for right and left channel, some capacitors to warm the sound..etc..

what all this translates into im not sure yet.... we will see next week when i set it up.
the only thing im wooried about is the latency on new rigs.....u might think say ddr4 4000mhz must be faster then ddr 1600. well its not....it has more bandwidth though...which is useless now a days. But....it has way more latency...like CAS 15 instead of my current 2cas, 1 command time good old DDR 3.

my goal is near realtime for playing or something like playing my module directly...:-)
......when i want quality i just pipe my sound into my denon amp via coax spdif.

You cannot apply the wisdoms of gaming here. In the audio world low latency is accomplished by having a soundcard with native ASIO drivers and running it with as small a buffer as possible. The better CPU and RAM you have the smaller buffer you can run, so a reasonably good rig is useful too. I guess similar rules, as in gaming, apply for all the stuff you need to turn off in Windows in order to make sure that resources aren't suddenly waisted on something irrelevant.

So, try a soundcard with native ASIO support. Borrow one. It doesn't have to be an RME.

Here is a good page https://help.ableton.com/hc/en-us/articles/209072289-How-to-reduce-latency

hi thanks for your reply. 🙂

i got the new rig running: z370 msi gaming pro ac, 3ghz ra, intel 8600k 6 core running 5 ghz, realtek 1220 (awesome headphone amp btw) saves me a mixer in my latency loop.
im down to 64 samples 2.8ms + 1.5 buffer on the new rig . So i guess it feels better now. the reatek even had an asio driver which was new to me....it sux however. 🙂
havent measured actual loopback latency though...
so... 2.8 + 1.5 + 1-2ms for midi , 6ms midi generation for roland td12.... gives about 12ms, to that one must add what happens after the driver....maybe 5-6ms more.
it feels alot better though.

following your advice im looking for a non pciEx RME card now.....but theres not many....and the reported latency are sometimes just hype...its also what happens after the driver which is key to success. but since using higher sample rates lowers latency or so i read .....something with native asio would give even lower latencies i assume.
the asio4all is only 44khz....or at least i can only get it to work with 44.

i found only one candidate maybe you have a few tips on specific cards? 🙂

the maya44 will fill my needs for a quarter of the RME price,, except it lacks a faster midi interface than roland mk2, but im not suspecting midi to be the big culprit in latency.

https://www.thomann.de/gb/esi_maya44_ex.htm

it all looks good on paper....but...i also found this information about the card which explains its REAL latency(loopback). which is not all that good ...
im not an expert and maybe this guy is off track ,,,,but considering the huge amount of latency information on his site....well. 🙂
its not the exact same version card though.
http://www.michalkaszczyszyn.c.....4_xte.html

i checked the ableton page....and it dosnet really give any advice on which cards will work...

have nice day

edit: i found the emu 44 pciE also.... im gonna look into it. http://www.creative.com/emu/pr.....?pid=20022
