Hi, I have a similar problem.
I have 4 clips from 4 mic in a nearly 4 hours project (that's many 4^^). After 33min, mixpad plays only de 4th clip...
Here are the answer of your questions you asked before :
1. What version of MixPad are you using?
The free-one, I'm trying it before buy it for my audio podcasts.
2. When you say 4 clips, are each of these songs their own separate MixPad project?
3. Have you recently moved the project files to a new directory?
I copy it on an another harddrive to work with another computer, but the problem appears on all computers.
4. If you look for the files in Windows explorer, each project file (.mpdp) should be paired with a folder which should contain all your audio data. So, for example, if you have a project called MySong, then there will be a project file called MySong.mpdp and there will be a folder called MySong.mpdp.ProjectData. Can you check to see if these folders exist?
Yes, I have 4 .aud and 4 .grf.
Thx by advance.
