Problem with playback

HELP. Ok its all set up and installed to the manual/tutorils. Records fine no problems. When the track is played back it sounds like it is being played through a VOX amp with tremerlo & reverb on it, it also has a harsh click/ pop ticking away in the back ground. This also applies when the sample tracks are played. However when converted into wma it plays back fine and as clear as it was recorded. i have tried for days uninstalling re-installing thumbing through the manuals with no joy. Matt

Re: problem with playback

Hi, I have the same audio interface. Alright, make sure that all of your effects are turned off. you probably (and most likely) have the "fx voice", "amp drive", "chorus" and "delay" effects turned on (bottom row). There is no way you should have distortion with tremolo & reverb on playback all the same time without the effects being turned on. the pop ticking could be produced by the buffer size. If youre using Sonar LE, you should tweek the buffer size until playback sounds smooth. I hope I helped! Good luck!

Alesis io2 guitar inpu and mute playback for backing track in audacity

Audacity is a copyrighted audio source and does not permit you to record tracks or playback of any kind. you will need to D/L the audio file you are trying to record in tangent and then play them together through an audio remixing app, like Ableton live or FL Studio

Im having a digidesgin mbox 2 connect to my mac.. and am using a pro tools 8. But when i click records (as i had plug in the mic) there will be no signal detected tho my headphone have a sound there! And...

You need to make sure that your Protools 8 is routing the tracks to the headphone. Check that by seeing whether the M-Box is set up as your output system as well as input. Having MIDI thru has helped me with that problem before even though it has little to do with it.

No sound in playback (but can hear click track)

This might seem simple, but just to check: you have switched off the monitor on the track when you go to playback? With track monitor engaged, you will not hear playback, but will continue to hear the live monitor.

Recordings play but skip every other second

you either don't have enough space on your computer for it to find the file and replay it(computers don't record in one solid track ,they take pieces and store them where ever they can.This is why its not good to defrag your comp. once you start a project) or you need to increase your buffer

Microsoft re-engineered the audio bus for Windows. HD Audio is hardware specific, in the sense that specific drivers have to be written to make a piece of hardware compatible with it. Roland is not writing a driver for the UA 25 because they want you to buy an UA 25EX. Get my drift? The UA 25 uses Kernel Streaming, the old way, which exists in parallel, sort of, with the HD Audio bus. But the new ways are always prioritized over the old ways in software, so there is bus contention (glitching).

To fix this there are a few things you can try:

1) Roll back to SP2. SP3 implements the HD Audio bus, so don't use that implementation. If your laptop has an HD audio sound card then I doubt it would work, but your UA 25 would.

2) Try ASIO 4 ALL. This fixed everything but glitching in VST instruments.

3) Reduce the amount of stuff your computer is doing. Optimize your OS by turning off the cute shaded windows and desktops and various processes that you don't need to see or use. There are sites for this. This increases available RAM, CPU time, etc.

4) Video hardware acceleration, sometimes, would fix bugs in software left in by not so clever programmers.

4) You can always just give-up and go along with the bastards and buy new stuff and toss the old stuff.

Mic problems: playback works great through interface, microphone isn't being detected

Check in contraol Panel under sounds and audio devices that you are using the Edirol and not an on board sound. It sounds like although the cards installed its not selected as the audio device to record from. You will also have to tel Adobce audition to select the Edirol as you audio card of choice as it to can be changed to select input from other sound devices.

Sound coming through computer speakers instead of through fast track.

Check your audio settings to make sure that it's going to the right driver. goto: start -> control panel -> sound and audio devices out of the 5 tabs, you'll want to pay attention to 2 of them, these are the "audio" and "voice" tabs. Make sure that your speakers on are the external sound system's drivers and not your internal sound card. (Basically, make your sound playback the same as your sound recording)

Timing and noise

That's usually caused by problems with the usb port on your computer. The best solution would be to buy an PCI USB CARD that you would use only for your UAFX4.
