I love the concept, it looks like a fantastic tool for semi-random pitch variations etc. BUT: it is not 'trigger-able' - it just starts playing blindly as soon as you engage the transport, so it is useless in a live situation. Come to think of it, even for sequencing: who says I want that particular sequence to be the very first thing that happens?
That said, if they add some user control to the triggering, I would buy this in a second.
We've been busy in the updating of Stochas, so apologies for not getting back to you both here. Firstly Ableton unfortunately is a handicap from within, it does not permit internal routing of MIDI like all other DAWs, it just smudges any outgoing MIDI data into a single track, the only work around is multiple instances of Stochas, which then means you're losing out on the layers feature of being able to view another layer underneath, unless you save out a patch and load it again into another.
The live triggering is something we are working on at the moment, hopefully we can get this into the next update. The one issue we have is Stochas is tempo dependant, so we're trying to get a good way of listening to the DAW clock and syncing playback to the start of a beat or bar, and have this as an option.
