It's a shame that they didn't at least do the standard summing trick to generate high pass of different slopes from the low pass taps, because in the Voyager you can actually select how many poles of low pass you want, so they do have some switching to access each stage.</div><div><br></div><div>Cheers,</div><div><br></div><div>Andy </div></div></div></div></blockquote><div><br></div><div>PS: I don't know for sure that the Moog Ladder 500 series actually does do a resonant high pass, so it would be great for someone to confirm this, and also if the 12 / 24 dB selector works in HP mode.</div><div> <br></div></div><br></div></div>
