Hi there.

I've been using PT for years, but for the first time I've just tried recording with effects using the input monitor. If I check the input monitor box in audio prefs everything is ok, but as soon as I check the box for allow input effects recording, all the tracks playback distorted. I'm using asio drivers and I've made sure that I'm recording line in, not the mix or stereo output. Even if I load a song which was recorded previously, as soon as the boxes are checked the distortion starts. Un-checking the box returns playback to normal.

Am I missing something obvious here? Anyone got any ideas, or had the same problem?

What soundcard?
What bitrate are you using?
Have you experimented with bitrate or buffer size?
What input driver?

Hi rharv,

On this machine we're running XP professional with PT 2010 and using the on-board Realtek audio. The drivers are ASIO4All 2.8. File type is 16 bit at 44.1k.

I've tried all buffer sizes from min to max with no change. Strangely, the same thing happens on two other machines which we've tried.

Basically, if you start with a blank template, the first track records ok, but when you try to lay down further tracks, the recorded ones play back really distorted making it impossible to record the new one. Weird or what? Any ideas? What happens on your machine?
I don't use this facility much, but it would be nice to know how it works! Any help is greatly appreciated, thanks.

I had the same problem - I unchecked the two boxes top right of the Audio Panel and the problem went away.

Hi Lyn,

Thanks for the info - it's nice to know it's not just me. If anyone else reads this and can check it out on their machine, please post the results. It could be that we've found a bug! I've made tech support aware of the problem, so we'll see what happens.

Are you doing it this way? Step 9&10 is what throws people.
1. switch to ASIO in the prefs audio
2. check,"enable IM monitoring"&"Allow IM effects recording.
3. click drivers tab
4. select the drivers you have
5. set buffers by clicking on "Asio control panel"
6. OK, OK OK until you're back to the main RB track view
7. Make the track RED that you'll record to & rt click to set it to an audio track.
8. Click FX tab
9. Tricky part here- click on the "track" drop down.
10. scroll to the bottom and choose "Input monitor insert"
11. click on the "plugin"drop down
12. choose your effects in 1-4 slots
13. Good luck

Hi John,

Yeah, that's the way we're going about it, except that we're on PT 2010 and you appear to be on RB. Still got the problem on three machines that we know of, plus LynB's post. It does start to look like a bug. No explanation from tech support yet. I'll keep you all up-dated. Thanks.

Hi all,

Rob at tech support has just got back to me to say that this is a problem, but it only happens with ASIO4ALL drivers. Development are going to look into it further.

In the meantime, I suppose you can always record whilst listening to the effect and then render the track by going to EDIT - AUDIO EFFECTS - DIRECT X AUDIO PLUGINS. This works even with real-time VST effects such as amp simulation and loops the audio whilst you audition the settings. In some ways this is almost better, because you can, for example, play using overdrive and reverb, but only render the overdrive and leave the reverb until the final mix.

Thanks for the input everyone. Hope this is useful.

This problem iss not confined to ASIO4All.

Hi LynB,

I'm just passing on what tech support said. Rob could only get the problem to appear with ASIO4All so he assumed it was something to do with it being a wrapper and not a generic driver. I was looking to change my input path, so it's good to know that this might not make any difference, thanks. What system are you using?

ROG.

I can say that on my system using native ASIO drivers & PT 12 all is fine.

I agree. I've used EMU 1212m & Tascam US1800 ASIO drivers & got the same buzz/distortions.

I too, am using PT2010. I did NOT have this problem in PT12 (Although both have other issues; e.g. terrible 'memory leaks' in XP SP3!).

My irritating but, play-thru effective 'buzz' work-around was

• to keep an "empty" track nearby (within an easy mouse click)
  
• After I play thru, and my Buzz starts, I Solo the empty track & press play then stop & un-solo.
  
• The Buzz stops & I can play/record again- until the play-thru ends. Then, I may need to redo the above.
  

In computer programming, this may indicate a Code Bug w/Win+ASIO. Some action is left UN-terminated (looped, etc), causing some Hardware to remain actively sending signals thru ASIO.

I'm curious, if PT2012 solved this issue.
