That’s my issue with ST/AR. Once you try doing something different than techno, you need x2 amount of money for outboard gear to make it sound good enough for a commercial record. Otherwise, it’s just too dark. So, just use samples, man! With AR I sometimes run the synth kicks through AH or SSL and sample it back. You can do the same on your OT, sampling in through an EQ and compressor.

Weird enough, A4 does much more interesting kicks as it has 2 filters, 2 envelopes, 2 lfos and a noise generator.
