Synthia -> Amplifier Panel -> Gain doesn't go below 70%

Though it may look like a bug, in fact it's normal behaviour that is a consequence of how MU.LAB works:

The Gain parameter in the Amplifier subpanel is also controlled by a Meta Parameter on the front panel i.e. "Limiter".

If Limiter is all down, then Gain = 70%, if Limiter is all up, then Gain = 100%.

And so when changing the Gain parameter itself, this Meta Parameter is updated too so to maintain parameter value consistency.

OSX

On startup MU.LAB alerts: "Can't find graphic resources -> quitting".

The MU.LAB zip package includes a couple of subfolders and files that MU.LAB needs to operate properly.

When you have extracted the zip package, and you want to move MU.LAB to another place on your harddisk, then make sure you move the complete MU.LAB folder, not the application file only.

If you're sure the MU.LAB folder is complete and you still get this alert, then note that when this situation occurs MU.LAB generates a Log-yyyymmdd-hhmmss.Txt file in the Mulab folder. If you have a minute of time, please email this log file together with your mac model + processor type + OSX version to . Thanks in advance.


Launching MU.LAB for the first time on my multi-monitor system only gives a white window.

It could be that MU.LAB is suffering from an internal OSX quirk.

Try disconnecting the second monitor and try again. Once you have agreed on the License Agreement, and MU.LAB is running, quit MU.LAB, reconnect the second monitor, and relaunch MU.LAB. Doing this may make it all work OK.

Of course we regret having to offer such workarounds, but in our opinion it is OSX which is to blame. And we won't invest our precious development time to R&D workarounds for OSX quirks, especially when OSX is likely to change everything again in its next update. We're doing our best to make MU.LAB as OSX compatible as possible, but we really hope OSX will soon stabilize, API-wise.


In MU.LAB's Audio Setup, only audio input OR audio output show up. When selecting audio input, MU.LAB doesn't play, but when selecting audio output, you can't record anything.

It's an OSX issue.

On systems with Mac OS X 10.4 or later, sometimes the audio input and output use separate drivers, and thus show up as separate devices in audio applications, leading to the fact that you can't use both at the same time.

The solution is to make an aggregate device that uses the input/output from different audio devices on your system, and showing up as 1 device in audio applications.

This can be done via OSX' Audio MIDI Setup.

Windows

Windows 7: Changing the files in MU.LAB/Settings doesn't have effect. And/or Windows 7 complains about security/administrator issues.

Due to the Windows 7 Virtual Store mechanism, not everything is allowed on a Windows 7 system.

The simplest way to avoid these problems when using MU.LAB is to install MU.LAB outside the 'Program Files' folder, but e.g. in C:\Applications\Music\Mulab (or any other non-system folder).
You can simply move the Mulab folder around to this new location, no problem, as the Mulab folder is 100% self-contained.


On startup MU.LAB alerts: "Can't find graphic resources -> quitting".

Make sure you unzip the MU.LAB zip package with the "Use Folder Names" option enabled!


The CPU meter is behaving strange.

It's a Windows issue.
