Playback Monitoring / Recording - How to remove delay?

Post » Tue May 18, 2010 2:58 am

I may not have the right software for this, but here is what I want to do - and here is the problem I'm running into:

I have a bunch of really great drum loops as .wav files. I also have some really nice VST synths, etc. that make some wonderful sounds. I'd like to set up the wav files as a loop and then play on my keyboard controller in real time and have the software record the midi data, etc. Here's the kicker: I'd also like to monitor what I'm playing in real-time. Here's my setup:

Roland A-90
USB MidiSport 2x2
2.4Ghz P4, 1.5GB RAM, 40GB 7200rpm HD
SoundMAX Digital Audio Soundcard on the Mobo (ASUS P4S8X-X)

The Issue I'm running into is when I set up the Soft Synth, there is a delay between when I press a key on the A-90 and when I hear the sound out of my computer speakers. This is the delay in the Audio Tab > Playback buffering slider. Trying to play with a tight drum loop and hearing yourself .25 or .35 seconds later is really annoying and much more difficult.

Do I need to get a "better" soundcard to be able to remove this delay to allow true "Real-Time" MIDI Control. As it is now, I'm controlling it real-time but not hearing the result without a substantial delay. Making overdub recording impossible. I've tried setting the slider down to .01 but I get garbled noise instead of sound. The lowest I can set it is .15 which is still quite long.

Can ACID let me play real-time with loops, without going through the "Playback Buffering" delay? If so, how?

Thank you in advance for all your help and consideration.

In short, yes, you would have to invest in a new soundcard or audio interface for low-latency recording, preferably one that can use the ASIO driver model if you're using MIDI as you are. (You can get comparable results using the WDM/MME model but that depends on how good the drivers are written.)

Echo's MiaMIDI is a good solution. I'm sure others can chime in.

Thank you for the quick response - I had figured that the sound drivers that came with my Motherboard (this computer was originally set up as a gaming rig) wouldn't be good enough.

So it would be the better drivers and/or the hardware on the card which would allow more accurate playback. I would assume that when I would install the new soundcard / interface that there would appear new drivers in the Audio Tab in ACID and then I could turn Playback buffering off? Or would I have to go down to .01 seconds?

Thanks again for your help - I'd really like to use ACID to it's full ability, I think it will let me do exactly what I want.

Well, Here is the result:

I just picked up a M-Audio Audiophile 24/96 and it works like a champ. $150 at my local Guitar Center. Returned the USB Midisport 2x2.

When I installed the Drivers for the Audiophile and told ACID to use it for Audio Playback the entire "Playback Buffering" line dropped to gray and now everything is truly "real-time".

I'm much happier =)

Thanks for all your help.
