Can someone explain what ASIO drivers do

Hi, I'm getting a new soundcard soon, It will probably support ASIO

What exactly to these drivers do?
Do they reduce latency or something?

Just a quick explaination would be appreciated

Thanks.

Have done a search by the way

It stands for "Audio Signal In Out". Yes, generally speaking, ASIO drivers have lowered latency. Porgrams like Cubase require ASIO drivers to run. Stienberg have their own MME and DX ASIO drivers if your card does not have its own but these are never as good as card specific drivers.

Probably? Make sure the card has its own ASIO drivers. M-Audio, Terratec. These tend to be the more popular choices for electronic musicians.

so, do i need to get it change to ASIO as wat i using now on my sequencer. (Cubase/ Reason)
i reckon i using MME.

Beside, whats the diff of VST and VSTi and Cubase SX and Cubase SL?

care to help?

If you have installed Cubase, then you have ASIO drivers on your computer. When you install Cubase, it installs ASIO MME and DX drivers. The only reason you should change your audio driver is if you have a better one. If you are using an MME ASIO driver, then I'd hazard a guess that this is the best driver you have.

VST = a plugin
VSTi = an instrument

Cubase SX = Full Version
Cubase SL = Limited Version (does not have all the features of SX)

thanks mate.

SO if im using M audio 6/6. Best i choose MME or ASIO?

need guidance. thanks for that.. it really do helps

ASIO is software developed by Steinberg and means Audio Stream (not Signal like cheggy said) Input Output.

With normal drivers, all the information is passed and processed in the OS first, which results in rather high latency. To reduce that latency, Steinberg made ASIO. With those drivers, the signal is passed directly between the audio program and the audio interface, not through the OS (or not as much). So you can have playable latencies (play in real time, or do overdubs).

Now, not all cards accept ASIO (mainly consumer ones), so Steinberg made some generic ones (well, more kinda ASIO wrappers for Directx and MME). They aren't nearly as good as the dedicated ASIO drivers for the audio interface, if they have some.

So, the prefered order in which you must choose the drivers :

- Dedicated ASIO drivers, generally it's written something like ASIO "model name of the audio interface", for example ASIO M-audio Delta66
- If those don't work, look at ASIO Directx. Like I already said, it's a wrapper, and Directx is a OS api, so using this will result in higher latency than the dedicated ones
- If neither of the above work, you'll have to choose ASIO MME. Frankly, if you're up to that point, better look out for another audio interface, or if there aren't any dedicated ASIO drivers out there that work. Because MME is really the crappiest of all.

ok. thanks alot mate.. thanks for clearing the confusion of what i had when i kept thinking what da hell was that.

millon of thanks!!

Cheers!

It's all about the latency. When I'm using MMX then i got about 700ms and if ASIO then 40ms or less

If you dont want to use some VST'is with MIDI controllers or record audio then MMX is OK but in the end of 2003 you will need it!! 100%

For example: my friend is using YAMAHA A3000 sampler with Cubase VST 5 and the sequencer is controlling only MIDI data and no audio data!
Yamaha sampler has already good soundcard builded in!! With low latency ... ok nevermind that post!! You need ASIO hehe

Your driver should be called "delta ASIO', or something similar.

ok. thanks mate. for the wonderful knowledge. but somehow, if i wanna check whether my CUbase SX is using ASIO, which and where can i check? and the bandwidth should be set at where?

When i play my MIDI on my syth using FM7/ ABSYTH as VSTi, i find that when i trigger each note, it will give a long latency before the sound came out. How can i solve that?

thanks

Devices --> Device Setup --> VST Multitrack

On the right, there is a drop bar titled ASIO driver. The driver you are currently using is here.

I checked.

I had 3 option:

ASIO DIRECT X FULL DUPLEX DRIVER
ASIO MULTIMEDIA DRIVER
M AUDIO DELTA ASIO

By default, it had set me to ASIO MULTIMEDIA DRIVER. So do i need to switch to M Audio Delta ASIO?

How about my Disk Buffer Size and Number of Disk Buffer?

Currently mine was set to:

Disk Buffer Size - 128K
Number of Disk Buffer - 4

Anyway, I would like to ask that I had manage to finished my song n found that my song was 90Mb that big. Was it normal or..?

And by the way I would like to burn the whole Cubase .cpr of my data song as backup or might do a remix or to keep. But find out that it reaches 1Ghz that big. So, does going into POOL and click Trash Bin and then right click to choose EMPTY TRASH?

Will that affect anything when I clicked that? WOuld like to know more and still learningstage of Cubase SX.

thanks a millon to the infinity, mate

Yes, you want to select M Audio Delta ASIO.

Buffer looks okay. That's the same as what I have it at. The latency settings are in the hardware settings in the soundcards's control pannel.

As a .wav file, 90MB seems about right for a song.

As for your file being 1GB, this was answered in another thread recently. Have a look for it. It explains how to reduce the overall size of your file.

ASIO DIRECT X FULL DUPLEX DRIVER = 40 ms
ASIO MULTIMEDIA DRIVER = 700 ms
M AUDIO DELTA ASIO = 4ms

Hopefully your not gettin an audigy and if you are send it back. I run a MOTU 828MKII with 4 MS stable latency running over 20 tracks on a laptop, no problems. Before my 828, i used an audigy, good card, but not for audio production work. Stick with the delta's or tertacs for that price range, you cant beat 'em. They have great ASIO support and work well with cubase. If you wanna check out some better PCI based cards, look into the RME/Hammerfall series, IMHO, they are the best PCI based cards on the market, and thousands of happy users cant be wrong. Ive herd nothing but good things about them. If you own a laptop, you might want to look into some external interfaces like my 828mkII, or something a little cheaper like the m-audio firewire 410, or even some usb based ones like the little tascam usb one that just came out and i cant remember the name. it was great card, just not for my needs at the time and i upgraded to the 828, and dont regret it. You get what you pay for.
