additional parameters: irate, ioff1-ioffn


This instrument allows the movement of a cluster of frequencies
in a linear fashion. The breakpoint function f35 specifies the
trace all frequencies will follow. On that trajectory the
partials maintain the same absolute distance from each other. The
exact intervals are given by the set of ioffn variables: in this
scheme half of the frequency components are within LFO range and
the other half is just outside that range (4.5, 9.4, 23, 39 and
84 Hz offset).

The variable irate controls the time needed for one complete
scanning of this function: in our example it takes 20 seconds.

The tone gives the impression of a starship during take off.
