In addition to that, the Sound on Sound article about the XL mentions some omissions on the Voyager edition that were on the original: A440 mode, plus filter topology. A passage from that article says:
~BenSo do I have any concerns about the XL? Of course I do, and here's a short wish–list that would make it an even better synth. Firstly, please can we have the Minimoog's A‑440 oscillator back? This is almost essential on a synth that has no fixed tuning. My second wish concerns the filter topology. As it stands, you can switch the Voyager's filters between series (HP+LP) mode for single‑channel band‑pass effects, and parallel (LP+LP) mode, with the output of each filter passing to a separate output channel. But wouldn't it be great if the dual‑LP mode was also available in series? The Cwejman S1 MkII shows what can be achieved with slopes of greater than 24dB/octave, and slopes of up to 48dB/octave would allow us to create some powerful new timbres on the XL. Thirdly, I wish that the XL's voltage processors were not modelled quite so closely on the CP251's because this means that there's still no patchable VCA. I thought that this was daft on the original expander, and I still do, so can we have one (or more) please? Pretty please? Finally, I would like to moan about being asked to pay $79 for the Voyagers' editor/librarian. If I'm going to cough up over four grand for a synth, I don't think that it would be unreasonable for this to be included.
