Hey Mike - good to see you here again after the forum meltdown. I'm glad most of the review was done before those problems occurred, but at least things are working well now.
Speaking of which...after more than 225,000 page views and almost 600 posts (!), I think we’ve pretty much covered everything there is to cover about the XW-P1. With Casio now establishing a user forum, it’s time for this review to wind down, although like all pro reviews, it will remain open for the three or four people left on this planet who haven’t heard about the XW-P1, or for any follow-ups that relate to the thread.
However, there are two pieces of unfinished business: a coda on the XW-G1, and the conclusions. So, let’s look at the main points of differentiation between the P1 and G1. Much of this is excerpted from the XW-G1 review I wrote for the October 2012 issue of
Electronic Musician magazine, as my opinions of the G1 haven’t changed since then.
First, there’s a philosophical difference not unlike the familiar synth/sampler dichotomy.The P1 is more about multiple synth engines for hardcore synthesizer fans, while the XW-G1 is for the more groove/DJ/sampling crowd. Although cosmetically they look similar, there are quite a few differences “under the hood.”
The G1 dispenses with the P1’s Hex Layer and Drawbar Organ engines, replacing them with a Sample Looper and a flash memory-based Sample Player with 10 presets. Available RAM for sampling/looping is 19 seconds with mono signals at a 21kHz sampling rate; halve that for stereo or when using the 42kHz sampling rate. Files can then transferred over to Flash ROM as user waves to free up the RAM buffer.
The P1’s assortment of PCM Melody and PCM Drum Tones, which you can think of as a sort of super General MIDI module whose sounds range from adequate to outstanding, remains intact but more importantly, so does the Solo Synth and its “Minimoog thinking on steroids.” A G1 Performance stacks up to four sound engines (one Solo Synth, and the rest PCM Tones or user Waves).
The G1 also adds some control features not found in the P1 like the Multikey feature, which allows using an octave of keys as trigger controllers for various functions. The 16-step Step Sequencer is similar to the P1’s but has a few differences (9 tracks instead of 16, four controller tracks, and a couple additional ways to trigger it) and like the P1, there’s a 16-step Arpeggiator and Phrase Sequencer. And yes, there are the same normal and wacky options for external audio as the P1.
But the main differentiation involves looping and sampling. The looper does what you’d expect, but more—like being able to re-sample sounds from within the G1, although you can also plug an instrument into the back and treat the looper like a stand-alone effect. It can also work with sampling (described later).
Sampling does some things well, some things superbly, and some things . . . not so well. Transposing a sample across the keyboard works great—transposition quality is good, and the G1 recognizes a sample’s loop. If you try to transpose way out of range, it just repeats the adjacent octave that’s not out of range.
However, multisampling is non-standard; a G1 user wave tone has only one sample, so there are no conventional multisampling split points. Instead, you assemble up to five samples consecutively, one after another. Each “split” then specifies the start and end of each section within the sample; in other words, each split plays back a different portion of the sample. Each split can loop from an arbitrary point in the middle to the end but for instrument sounds, you can’t specify the loop points with sufficient accuracy to do short (e.g, only a few cycles) loops. Nor can any sample editor I’ve used generate multiple loop points within a single sample that the G1 will recognize. If you want a multi-sampled cello, this is not the droid you’re looking for. On the other hand I was able to take a single sample from a Paul Reed Smith bass, stretch it over the keyboard, and it sounded great. Note that sampling RAM is not expandable, but I didn’t bump into too many limits, given the G1’s intended application.
While Casio’s approach is a little awkward for conventional multisampling applications, it’s a
very different story if you have a sampled phrase like a piece of music. Defining different sections, mapping them to keys, and being able to loop them makes for some great breaks, DJ-style loop mashing, sound effects, stutters, and more. What’s more, the looper can fit this like a glove—for example, it’s easy to record five consecutive step sequencer sequences, shuttle the wave into a tone, and the G1 automatically sets the split points and you can start playing immediately. The integration among all the G1 elements—looper, step sequencer, sampler, arpeggiator, etc.—is a
major strength. Like the P1, there’s Editor/Librarian and it’s every bit as good as the one for the P1.
Overall, the G1 is just as much fun as the P1 . . . and for groove fans, perhaps even more so.
