Hello everyone I am new to recording and this forum so first off hello :D . I posted a question in the recording section about importing files from the 1600 to cubase that problem is fixed now thanks alot :-) now I have another. As I wrote in my other post a friend of mine just closed his recording studio I used to goto him for my recording needs so when he closed I thought I would buy some of the stuff he was selling and start recording my own stuff I do run FOH stuff so I should have the ear for it after I get used to the process. I bought a very nice pc and alot of software from him. Now the problem is alot of new software and most of them with steep learning curves lol so I am running into alot of road blocks the newest one is I had an M-Audio delta 1010lt card I was using to record with, it had direct monitoring I used it for my main audio interface. When I used ez drummer with it the drums were in time with the song when I was recording ( when direct monitoring was in use) and when I would replay the track it was still in time. Now I traded that for a more portable unit the Presonus firebox 6/10 unit when I am recording and direct monitoring is in use the drums I am playing with ez drummer are in time but when I replay the track the drums are a few m.s. behind the music ( the music is just a song file I imported into cubase to get the hang of ez drummer to play along with). My latency is 2.042 M.S input and 2.042 M.S. output. I am wondering why with this unit the playback of the drums is out of time, the delta 1010lt also had latency about the same amount of latency too but it did not have the problem of falling behind during playback. Well if anyone could help me that would be great. P.S. I am using a roland SPD-20 to trigger ez drummer if that matters at all but I don;t think it does.
Thank you Leadplayer, John Dullebawn

this is hard to diagnose without fooling around with it...is your firewire onboard or a add on card?

Just a stab in the dark, but I would guess the latency is coming from your firewire chipset...there are known audio issues with windows firewire interfaces that do not have Texas Instrument chipsets

Well I am currently using one off a creative audigy 2 platinum card ( I am using this cause I have a game port to midi adapter so I just use the audigy for the firewire and the midi. not audio lol) I also have a firewire port on my motherboard its an Asus Maximus Extreme board maybe that will speed things up? Also the firewire box is currently just being powered off the firewire line. I could go buy a power supply for it to power it directly it says in the book that you can just power it with the firewire line but maybe I should power it with a wallwart? Thanks for the input I will try it first thing tomarrow getting late and need sleep [-o< .Will post the results tomorrow thanks again bro.

:shock:

You don't mean seconds do you ?

Firewire is definately the way to go. My latency in Sonar PE6 is reports consistantly less than 10ms. on a Windows XP platform.

Most software recorders have a way to let the program select the drivers that provide the least latency. The buffers can be tweaked some to further improved latency.

nope bro its M.S not secs about 2 M.S. in and 2 M.S. out the best driver seems to be the one that came with the unit even getting better latency than with ASIO4ALL but if its that M.S delay I am hearing I need to fix this problem as the drums are just too far off could not even do the bass track next. Plan is to do tuesdays gone from metallica as my first project to learn all this new software and hardware. Going to do the drum track while playing along with the orig. song then do bass, then guitars and finally vocals. But these drums on play back are just way to far off (late not early). I Am going to try the firewire port on the mobo and just bought a power supply for the firewire unit to see if that fixes this problem. Thanks for the input

Hi John, I don't think one would hear or even notice a 2 ms delay (except for when two identical tracks are 2 ms apart). You could always edit out 2ms of time to timeshift the track by 2 ms.

I could only wish I had 2ms latency. It takes a certain amount of time for the signal to pass through all the processing and as Rob says , 2ms is almost beyond human perception.

2ms of delay is not a latency problem. It is amazing performance.

My PC recording performance is anywhere from 3.6 to 6.0 ms (I had it down to 2.8 at one point). I don't hear or perceive any delay.

EZ Drummer is a cool program, but it can be testy. Do you have an input echo radio button in Cubase? If you do, check it on the audio track (not the MIDI track) where you've inserted EZ Drummer.

I figured 2 ms was not going to cause a big problem as far the the 2. ms delay it self but wasn;t sure if maybe the ms delay was causing other problems, I did check the settings in the audio track and nothing there that would cause this problem thanks for the input though. I did what jake said to try plugged in my firewire interface to another firewire port and I decided to power up the unit with a wall wart instead of letting the firewire power it and its all gone no more delay. So thanks again everyone 2 problems figured out here in 2 days thanks alot everyone. I hope to have a good grasp of things fairly soon. Best of luck to everyone.
