It's been a while since my last review of Conductr and since then it's really grown up. The initially four modules for Ableton Live were expanded upon with the Claydr MIDI Keyboard and XY-4D Pad. With the latest update the iPad controller got the possibility to control Traktor.
If glitch is your thing and you always wanted to be able to manipulate audio on the fly, then Grooveslice could get you quite excited. It functions as a parametric delay with separate parameters for recording and playback, and gives you a wide range of features for maximum control. While it can be a great tool in the studio, it excels when used for live performances.
If you're a drummer who wants to play electronic beats or just feel like a bass drum needs to be played with the foot, check out "Sustain Pedal Kick Drum". This simple Max for Live MIDI effect allows you to play the kick with a sustain pedal.
Christian Kleine has played a very nice live concert at the Kompakt/Ableton Popup Store recently. Everything happening in Ableton Live was projected on the wall behind him. I took the opportunity to film it and I have also asked him a few questions about his live set.
By now, there are already quite a few iPad controller for Ableton Live. Conductr, now in the App Store, has taken up the cause to be made specifically for live performance. And that in a very sleek and minimal design.
In a live performance situation you might want to see the play position of your session view clips to know when to start the next scene or clip. The track status in Live might be too small to use as a visual cue though.
