@Brandon_Tran, what kind of issues do you have? Just some lag, a noticeable latency even though it says “10 ms”?
Here is my configuration of ASIO (with ASIO4ALL), that brings the best result (Reaper is saying 4,6ms):
About the WASAPI error message I don’t have an idea, unfortunately. If you followed the steps above (connected properly to Windows, set them as enabled MIDI devices in Reaper …), it should be fine
But try a bit more around with ASIO, for me that’s the better option.
@braianoi, does any of your computers have Bluetooth Low Energy? Did you follow the steps above completely and all requirements are fulfilled? Can’t tell what the problem might be at this point
@jamadza, thanks for your feedback! I changed the buffer in ASIO to the minimal 64 samples and its coming along nicely I didn’t think it would work with less than 128 (that was the lowest before ASIO4ALL was installed), but it actually does.
