I use BCI2000 V3.6.beta.x32.extensions.

The following Steps:
1. Launched the BCI2000Launcher.exe, select LiveAmpSource, P3SingleProcessing, P3speller.
2. Config,add the P3Speller_CopySpelling.prm.
3. Set config, it halted with the error in the attachment.

the system log says:

The VisualizeSourceTime parameter specifies time without unit. Throughout BCI2000, time specifications without unit are now consistently interpreted as being given in sample blocks.
If your source display appears strange, try appending the letter "s" to the VisualizeSourceTime parameters value.

64-bit Library "LiveAmpLib2" could not be loaded, but is necessary for LiveAmpSource to run.
You may need to install the driver software that came with your amplifier. More information may be available at:

It looks like you have a 64-bit version of LiveAmpLib2.dll, but the BCI2000 distribution you have is a 32-bit one. Can you point me to where you downloaded this distribution?

Hi dmedine,

I work with minmin on Liveamp integration with BCI2000. I have both 62-bit and 32-bit versions of BCI2000. I tried both and they give same warning when configures in operator. Let me know if you have any other solution

Can you confirm that you have a copy of LiveAmpLib2.dll in the folder <path_to>\BCI2000v3.6\prog

I can use the LiveAmp on my system without any issues. However, I have access tot he source code and have built everything from there. This is perhaps a bit different than the 3.6 beta release.

Thanks. resolved the issue. The problem is with the incompatible beta release. I have made it work for 32 channel liveamp. Did you use it for 64 channel too?
