And I think that to know the spirit with which this challenge was created we must go to the "founding fathers".
I found this first comment of Tattiemannie (who is according to the OSC website the original founder), dated March 19, 2009, from which I believe we can extract the original spirit with which One Synth Challenge was created:

A broad approach I would recommend would be to disregard genre and to some extent, production quality. Its more about how the artist an the chosen synth have produced the range and quality of sounds necessary for the track.
so .... we dont go asking "why no brass?" in a folk tune, anymore than we ask "why no soft pad?" in a punk track....... The idea from the outset is to create a track using only one synth..... and the proof of the pudding is about how that challenge has been met, so it's not about the merits of the synth, nor the merits of the track, it's about how the artist has shown that the limitation of using only one synth, does not necesarily limit their ability to produce a quality track, in a style of their choosing.
So I suppose what we're looking for as a yardstick is the "wow! you did that whole track with one synth and hardly any effects????????" ...
I was listening to the first track that won the OSC-1, "Army of Synth1" made by Kaiyoti (who took 54 percent of all votes) and according to the comments of the contestants at that time, it seems that the "WOW" factor prevailed on that occasion.
From then on there were many modifications of the rules, but the true spirit I think they remain until today. And I think it's the following: The contestant who does the track with the most amount of WOW is the one who will win that month.
