Holy wars rule! [/sarcasm]
I can't speak for total newcomers but I know they are "out there," every now and again someone will wander into #mod_shrine, BotB, or SDCompo and try a compo round, but few of these people stick with it, so if it doesn't twist the question around too much, how do we keep these people interested?
When I want the MOD/XM sound I use an IT clone like Schism because I prefer its hotkeys, otherwise Renoise remains my instrument of choice for just about everything. I suspect most tracker users "graduate" to either Renoise or MPT (or abandon tracking.)
If you want to play an instrument with limitations there is always harmonica and kazoo. The "limits" in chip are an artistic decision like any other.
