I recently purchased an M-Audio Duo USB external sound card and I'm having difficulty hearing my guitar and the acid tracks simultaneously. I'm beginning to think that this is not a good sound card to work with acid. Any suggestions regarding this, or any recommendations for other external sound cards that work well with Acid pro 4.0? |

I have a Duo USB (and ACID Pro 4.0). Unfortunately, you cannot monitor while recording with it in software mode, even at a lower resolution such as 16-bit. (This really doesn't surprise me too much, knowing M-Audio's driver track record.) You can monitor while recording in standalone mode, but that, of course, totally negates using the Duo like a soundcard so you wouldn't be able to hear what's coming from your computer via USB. I believe the USB 2.0 and FireWire audio devices do not have this apparent limitation (since they have plenty of bandwidth to begin with). Anyone have any suggestions?

I have the same issue and sound card. The M-Audio site says that the Duo is capable of full duplexing, as is Acid. However, after setting up the card (16 bit 44.1 KHz) and Acid to monitor the mix (using Asio drivers), I can hear the previously recorded tracks, but can not hear the actual trakc I am recording. Are there any solutions to this issue, other than getting a new soundcard? |

I just got a tech support email back from M-Audio and they cvlaim that the full duplex should work with the Duo, that the problem must exist in Acid configuration (of course). Can anybody shed some light on what might be configured incorrectly on Acid? Thanks... |

You might want to email support. Be very detailed... and patient. |

I think M-Audio has it confused. Straight from the Duo's manual (pp. 13-14): "3. A “direct monitoring” capability can be achieved when Standalone mode is engaged while the Duo is in use as a digital audio interface in conjunction with your computer. This will give you zero latency monitoring of the signals present at either the Mic Inputs or the Line Inputs of the Duo. You will, however, not be able to hear the software outputs from your computer in this case, so this option may only be useful to you when laying down your first recorded tracks, i.e., when there is no other audio playing back from your computer." The only way to do monitoring while recording is to interface the Duo in standalone mode with another soundcard or audio interface. That or maybe M-Audio makes new drivers that let you do monitoring while recording. Iacobus ------- RodelWorks - Original Music for the Unafraid mD's ACIDplanet Page Guitars 4 Kids |

Here are two other excerpts from the Duo manual: Regarding the ASIO drivers on pg. 17: "If you are using an ASIO or EASI compliant music program, we suggest that you enable and use the Duo’s ASIO or EASI drivers. These drivers give you the advantage of being able to monitor your source through the program, often called “tape-type monitoring” and similar to monitoring the record inputs of a tape machine. Note that in Windows XP, 2000, and ME, the WDM drivers will also install automatically and can achieve the same results (with a program that utilizes them, such as Sonar from Cakewalk), yet do not need any special configuration or attention." and regarding MME drivers on pg. 16: "A music program such as Cakewalk’s Sonar takes full advantage of the WDM driver model, and can achieve extremely low latency when using their “Input Monitoring” feature. Sonar’s Input Monitoring will allow you to monitor your signal at the software inputs, allowing you to add software effects while monitoring. Check your Sonar manual for more information." They offer this software layer of monitoring as long as the software package allows it. Now I know I've seen other posts on here that insinuate that Acid's software monitoring capabilities are less than adequate (cannot apply effects during recording). My guess is some cards are able to play the inputs simultaneously with the audio output form the computer and the Duo is not. However, some apps are able to send both the pre-recorded audio and the audio being recorded to the card's outputs while recording (which would work with the Duo) but Acid is not capable of this. I want to be wrong here, can anybody explain more in detail? Thanks... |

You are right on both counts. A lot of pro-level audio interfaces/soundcards do the record/monitor thing internally. M-Audio's Audiophile 2496 and Echo's MiaMIDI are examples of such interfaces. I was a bit disappointed that the Duo could not do this by itself, but then again the Duo uses USB 1.1 too; there's not a lot of bandwidth to be had. ACID cannot do software-level record monitoring like Vegas 5 does—at least maybe not yet. But then again, it's recommended that the ASIO driver model be used in the case of Vegas 5, and even then I've heard it can be touchy. Personally, I'd rather do it via hardware rather than software. A pro-level hardware interface should do the task of monitoring, not the software. Iacobus ------- RodelWorks - Original Music for the Unafraid mD's ACIDplanet Page Guitars 4 Kids |

Hello, I agree with Md, but I also like to have the cards monitor as well. What I have is a small 8 channel mixing board in between the ins and outs of 1 of my sound cards, and this way I can use monitor speakers to monitor inputs. I think it was about $59.00 See ya, Rockitglider |
