• Manufacturer's Description

Sometimes, the best things in life really do come in small packages. The compact and capable Novation X-Station 25 was a case in point - it combined a controller keyboard, a synth, an audio interface, a multi-effects unit and a control surface in one portable unit.

Novation’s latest, the XioSynth 25, is probably best though of as a cousin to the X-Station. However, being both smaller and cheaper, the issue now is whether it’s just a watered-down version of its sibling or something genuinely (and usefully) different.

Controls

Physically, the XioSynth 25 is somewhat reminiscent of the original Bass Station and even more similar to the recently released ReMOTE LE. The two-octave, touch-sensitive keyboard can be moved up and down in pitch one octave at a time (a 49-note version is also available), and the 11 control knobs and buttons can be switched to perform a number of different roles via buttons on the front panel.

The XioSynth is quick and easy to set up and can be powered via USB, with a PSU, or from good old AA batteries. It’s generally quite simple to use, though some aspects of its operation aren’t immediately obvious. Fortunately, the bundled DVD contains a number of informative tutorial videos that explain everything in hands-on style.

Functionality

It does indeed turn out to be the case that the XioSynth lacks some of the X-Station’s functionality. Fewer controls are immediately available, the keyboard lacks aftertouch and there’s only one microphone level input (2-in/2-out audio I/O is provided, and there’s one XLR input with phantom power). Surprisingly, though, Novation have actually managed to squeeze in some extra features that you won’t find on the X-Station. The built-in synth has an improved filter and an extra Shape parameter, for example, and these significantly expand its sonic versatility.

The KS synth engine used here has been around for a while now, so full marks to Novation for bothering to improve it. It should also be noted that the XioSynth can load presets from all K-class synths (A/K/V/X-Station, KS4/5/R), so its users have a huge patch library to draw on. One thing you can’t do, however, is load XioSynth-created patches into the software V-Station.

While the X-Station can be used either in synth mode or controller mode, the XioSynth can work in both simultaneously via its Hybrid mode. So, you could trigger the built-in synth with your sequencer while using the control surface and keyboard to play and automate a soft synth. On the downside, there’s only space for 16 controller templates in the XioSynth’s memory, as opposed to the rather more useful 40 on the X-Station.

Another limitation that you won’t find on the X-Station is that the built-in effects can’t be applied to incoming audio. However, this restriction aside, the internal audio routing is actually more flexible with the XioSynth. Our favourite new feature has to be the X-Gator, which can be used to add trance-style gating effects to any synth patch. Furthermore, gating patterns can also be programmed visually on the LCD screen.

By default, the XioSynth’s front panel knobs are used in ‘pickup mode’. This means that the knob must be turned to match the current value (displayed on the screen) before the value can be changed. Although slightly counter-intuitive at first, this system actually becomes really useful when you start to switch the 11 knobs between their two roles, as it prevents their values from immediately jumping as soon as the control is touched.
