Hello Abject,
from the technical side it is possible, but it is very difficult. The FIlterbank-engine does not support re-sampling. Icarus runs at a fixed sample-rate wth 96 khz and re-samples the output. The Filterbank engine runs with the host's sample rate and does not do resampling. As a result the cutoff frequencies would be detuned and the resonance would get instable.
I agree that it would be nice to have more filter types available. I have added your request to the thread.
Best Regards,
Markus
