Sounds good. What are the min hardware specs for the computer running psych toolbox? I'm just wondering how much this is going to drive up the $$/rig? Are you still going to support the stereo server that you currently use (which is presumably cheaper)?
Hi Jeff
The major update has been pushed. Bpod now integrates with MATLAB PsychToolbox to deliver low latency sound, when the governing computer is running MATLAB on Ubuntu 14.04. Using the Asus Xonar DX http://www.asus.com/Sound_Cards_and_DigitaltoAnalog_Converters/Xonar_DX/ sound card, latencies for stereo 192kHz sound range between 6ms and 8ms, even with moderate CPU load. Since the sound card has 7 channels, all spare channels (L&R side, L&R rear, Subwoofer) automatically indicate the actual onset time to Bpod with a 1.5V TTL pulse, which is read by Bpod's wire terminals. This is better in principal than B-control, since you can account for the system's jitter on each trial, and align neural data to the onset of sound with ~100us precision.
Now that I've worked through sound, the next steps are to finish documentation. I'll notify you when the wiki is ready. You can view it in the meantime here https://sites.google.com/site/bpoddocumentation/(note the link to the Bpod Github repository under setup).
Also, the Pulse Pal wiki https://sites.google.com/site/pulsepalwiki/ is complete, and the Pulse Pal paper is under review at Frontiers in Neuroengineering.
If you're interested in beta testing the new Bpod, please let me know!
Cheers, Josh

Sounds great. Thanks for the update. We should talk more soon.

We are beta testing.
Is there a readme or install file somewhere that describes how to use the software?
