I'm just now moving from Reaper to Ableton as my main production environment (mainly to grab loops coming off my hardware). I've been thinking about picking up a second iPad from eBay so I can run Touchable and also be able to access Genome and other IOS apps at the same time. Ableton will serve as the master clock for my hardware via a Syncgen IILS, which will clock a Machinedrum, a 777, and Genome on the iPad, which I use together with a Kenton 4 channel MIDI-> CV converter to sequence the modular. Should be a pretty nice workflow. But first, I need to buy a new wireless card for my studio computer... it's currently offline so I can't use Touchable!
