I very recently pushed nyx.c thinking it was the same one pushed earlier by Steve. This version has some fundamental changes to keep reading/writing of multiple channels synchronized and insuring that the same number of samples are written to every channel. There are some minor differences like using printf instead of stdputstr and I tried to follow what I found in the nyx.c that has been in use for a long time.
