Dear Joerg:
I would be very interested to see - hear what you have written.
I am not a programmer but I work at it. So far as I am aware, it is not possible to get accurate microsecond timing when addressing the sound card togenerate pulses. Maybe you have the answer? ( BTW a 10 microsecond difference is significant! )
With my Brain State Synchronizer, I use Small "C" and the pulse routines are written in machine code to get the speed.
If you have a skeleton of the code that works I would be willing to try to fine tune it.
Let's see if you got something that works before you worry about option 1) or 2) or others.

Have you published a (medical) paper about that findings ?
I have now implemented an experimental version of the UP-mode
for PC (in C, based on the SDL library). However I am not quite
sure that I did everything right.
Because you have payed much money for getting the patent and advertise the
"Brain State Synchronizer" it seems to me that there could be conflicting
interests.
1)Is it OK for you, if I make the source / exe available to
this group ?
2)Is it OK for you, if I make the source / exe available to
the public as freeware ? (GNU license is not possible afaik, because
a patent is involved)
Before I do any of the above I would like to hear your opinion.
Regards,
Joerg
