I've had lots of successes before using the minibrute for synthesizing kicks. Though I do admit it's a little more challenging than with other synths, but that is due more to the behavior of the particular filter minibrute uses. I wanted to add that you shouldn't look at the Brute factor as just an 'effect', you have a minibrute, and brute-factor is part of its circuitry. Don't be afraid to use it! It does enhance sounds sometimes if used correctly.
I made the first half of this https://soundcloud.com/auxone/seq04filter
using only the lowpass filter self-oscillating (no oscillators at all until 0:48), and I managed to get a decently bassy resonance, and a decently heavy kick. It works. But like I said, it's called a brute for a reason! You should embrace those nuances of this synthesizer. Every synth has it's strengths. And the minibrute has its strength in being a brute.
