Moog ladder filter with Turbofilter/msoundfactory

[JoopB]

As an experiment I tried to make a ladder filter in turbofilter, Msoundfactory.

I understand that it is a series connection of lp6 filters with a feedback loop from the last into the first. I wrote:

fb1(fb)[lp6(f);lp6(f);lp6(f);lp6(f))

it does work but I cannot tell if it is similar to Moog ladder filter.
Does this make sense?
