using an external clock device (Big Ben) requires you set the Eclipse on external clock, rather than on internal. The Big Ben should clock Eclipse, not Eclipse itself.
Some programs can't run at higher than 48KHz sampling rate. The presets that show a "96" symbol in fron of their names will run at higher than 48KHz rates.
Running at 88.2 or 96KHz cuts DSP resources in half, so smaller programs only can run at such higher rates.
