Filters are second only to oscillators in defining the sound of a patch. If the oscillators were passengers
in a car, for example, then the filters are the doors: Some open and close luxuriously to reveal the
occupants; others have more grit and meet a different need. The Hydrasynth Explorer filters cover the
range from a silky Lamborghini to a rugged Jeep, with all the sophistication and aggression implied by
those extremes. You’re ready for any sort of musical journey with Hydrasynth Explorer.
There are two filters available, each with its own characteristics. They can be used in series, with Filter 1
feeding Filter 2, or used in parallel, where each filter has a direct path to the output.
filter 1
This filter is actually a collection of filter types. Each one has its own character, and some may be similar
to analog filters you have encountered. But we didn’t want Hydrasynth Explorer to sound like a clone of
any instrument, so we took some of the flavor of the original filters and made something new. As with
the oscillators, you will find that the Hydrasynth Explorer filters add their own signature to the sound.

compensated vs. uncompensated filters
Filter compensation could be an unfamiliar concept. It’s another way in which ASM has adapted the
sonic profile of various analog synthesizers. Here’s the difference:
• Uncompensated filters: As resonance increases the low frequency content of the sound
is reduced.
• Compensated filters: The bass response is
not
reduced as resonance is increased.

All of the Filter 1 types have the same parameters, with one exception as noted. Access [FILTER 1] and
