Creating a high-pass filter

To simulate a high-pass filter on the EssenceFM, duplicate your voice. Put a lowpass filter on the copy and invert the phase of every carrier operator. Phase inversion is easy to do for symmetrical waveforms like Sine: put the operator's Phase parameter to 63.

Now assemble both voices (the original and the copy) in one Patch to trigger them at the same time. You now have a high-pass filter. Its cutoff frequency follows the frequency of the lowpass filter.
