In fact, the majority of buttons are small, loose and too indented to provide tactile feedback. The smaller knobs and buttons such as the cue on/off and mix and volume knobs are horrible to touch and are much too small for a sweaty nightclub setting. The transport buttons are very loose and click loudly when pressed. The faders and jogs on here feel great but it's really let down by the buttons and knobs. The Aux input is one advantage that the Ergo has over the S2, if you put them head to head, though there's no volume control for the second out, if you wanted to use it as a booth output. USB provides all data and power - there is no power supply connection. Round back it's as expected - a stereo balanced TRS output, phono outs, mic and phono inputs with volume control.

There's no LED metering, but behind the volume fader does pulsate in red when a signal is present. It feels like while implementing this trick, Pioneer missed another in making the blue lights genuinely useful. This is definitely the Ergo's coolest feature, but it'd be much more useful if maybe the lights were brighter, depending on how much of that deck is 'on air'.

We wish the light show made more sense though - there's no way to really get useful feedback from them, apart from that an effect is active. Much like the CDJs, a red LED orbits the jog while it's playing, but once an effect or filter is active, 'Pulse Mode' sends the jog spinning with LEDs and colour, faster depending on the intensity of the effect.
