This approach will not work for a couple of reasons.  One is the that
the "if" is at i-time, so will loop four times during initialization.
Second is that you did use an arate loop, you still can not run an
oscillator like this.  What you will end up doing is effectively
running a single oscillator at x times the normal rate.  I assume you
want x number of different distinct oscilators.  The only way to do
that in Csound is to use a recursive User-Defined Opcode.
