More like the Buchla, but, yes, tunable. Just High, Low, and Mid would be suitable, or 2 mids. Really just a crossover.
The Electrix Mo-FX uses this simple trick so that you can have different effects on each band.

I believe Plan B has something closer the the EMS Filter bank, the M16:

The M16 Looks spectacular BTW, but a simple 3 or 4-way splitter would be very useful and complex enough, as, for example, you would already need 3 delay modules if you wanted to send each band to delay length.

best,
