Extra noises on playback and recording

[sinenomine]

I wonder if I could enlist your help.

My recordings and playback sometimes have extra noises in them, and sometimes it is difficult to eliminate them. Often I can isolate it to a single track or tracks.
In this example I have a Vivaldi file that is

VST 1
Violin 1 (GPO)
Violin 2 (GPO)
Viola (GPO)
Cello (GPO)
Double Bass (GPO)

VST 2
Organ (Garritan Classic Pipe Organs)
Organ Pedal Garritan Classic Pipe Organs)

I have isolated the organ continuo from the rest of the orchestra so this is VST 2 excluding pedal. (So the music will sound boring) Example 1 Every time I playback or record the same noises will be in the same place. However, if I close the program and reload the same file, the noises may be gone, or they may be different as here in Example 2. Then it gets complicated, a further closing and reloading, The continuo organ is fine, and the problem is in VST 1 in the viola part. Example 3
On occasion, it is not unusual for more than one track to have problems.

Program: Cakewalk Sonar X1
VST: Aria 64 bit (Standard or multi)
Windows 7 pro
This can happen with any samples from GPO; Instant Orchestra (especially timpani); Pipe Organs

Adjusting buffer size does nothing
Enabling write to disk cache has not helped
I have disabled Realtek in the bios as I use Asus sound card.

So any help or ideas would be appreciated. Thank You.

Are you really using such a high sample rate? Or is that just the max supported by your audio interface showing in all that text above? Unless you're doing some seriously sensitive recording with a massive dynamic range using top of the line microphones I can't see any good reason to use anything higher than 48k.

Try 48k or 44.1k

If you haven't already filed a support ticket through your MakeMusic account, give that a try. Someone will most likely have you run some diagnostics and exchange a few logs.

How does the PC do with a DPC check? ( http://www.thesycon.de/eng/latency_check.shtml )
( http://www.msfn.org/board/topic/140263- ... interrupt/ )

What kind of hard drive(s) are you running the sample libraries from, and how are they connected?

I had some issues at one time and it turned out to be some of my PNY SSD drives (or their drivers/firmware...I got two different models form them, but both are based on the same chipset/drivers and flash technology). At first I thought it was just an ARIA issue, but I later ran into other plugins that suffered as well. The crazy thing in my case is that the PNY drives didn't throw up any red flags in all of my DPC tests, but still, moving the OS page/swap areas, and any sample libraries that need to stream from storage to a different drive worked in my case.

It drove me crazy trying to find the problem, as the PC passed all the DPC Latency and burn in tests with flying colors. I went through a gradual process of testing all the voltages on the power supply under load, trying different locations and sizes of page/swap files...disabling drivers...physically pulling everything out of the PC and running the DAW for a session before adding something back (etc.). Eventually I tracked it down to some bad SSD drives (or at least bad for some of my soft-synths)!

As it turns out, my system does much better with the DAW if I don't assign any OS page/swap space to these particular models of SSD drives.
( http://superuser.com/questions/237813/h ... k-location )

I also discovered I don't want to try to stream small samples from these drives. Most softsynths are going to do exactly that! So I moved them all to a different model drive. Note...even with really old SATA2 platter drives, my sampler/synth plugin glitches went away.

To ease the trouble shooting process of trying the libraries from different drives, I just made a copy of my entire Garritan installation folder on a few different drives connected to different ports/hosts/etc. and used a symbolic link to run it from the different locations.

1. Open up a command shell in administrative mode. This is also known as an 'elevated command prompt'.

2. I use xcopy to copy the entire content directory to a different drive. The reason we want to use xcopy instead of using explorer for the copy is because it's important to preserve any ownerships and permissions set up by the original installer. Here's an example:

xcopy "C:\Program Files\Garritan" "E:\Program Files\Garritan" /s /e /h /b /i /r /k /o /x

( about xcopy - http://pcsupport.about.com/od/commandli ... ommand.htm )

3. I rename the old directory.
ren "C:\Program Files\Garritan" "C:\Program Files\Garritan.bak"
( about ren or rename - http://www.computerhope.com/renamehl.htm )

4. I create a file system junction to the new location.
mklink /J "C:\Program Files\Garritan" "E:\Program Files\Garritan"

(About mklink - https://en.wikipedia.org/wiki/NTFS_junction_point )
(More about mklink usage - http://www.sevenforums.com/tutorials/27 ... ndows.html )

If you need your original installation back, simply remove the junction and rename your folder:
rmdir "C:\Program Files\Garritan"
ren "C:\Program Files\Garritan.bak" "C:\Program Files\Garritan"

Note, using rmdir without the /S flag to remove a symbolic link or junction does NOT delete the directory that it links to on the other drive. It only removes the link. So, to try running from different locations, just use rmdir to get rid of your symbolic link, then create a new one pointing to the next location you'd like to try.

Good luck...

Thank you again for your excellent and detailed reply. It is very much appreciated.

There’s quite a lot for me to work through there, so perhaps I should start at the beginning. First thing I’ll do is reduce the sample rate. That is probably the most obvious thing to do. I’m not sure why I had it set so high. On thinking back I may have set it myself when the computer was new, I had (at the time) great difficulty in making a good quality sound.

The latency check considers that there should be no problems.

I have two internal Seagate disk drives. One for programs and operating system (C:), and another for data (E:). The Garritan samples are on the data drive.

Thank you again for your help, I will go through systematically.
