Henry,
      
      as Per already said, that's some serious gear alert here!
      In fact, there's some things I use, too (Waldorf Q, Yamaha FS1R,
      Korg Wavestation, Matrix-1000, Kawai K5000R).
      
      I can't say that I completely understand everything you're trying
      to do here...you are playing a part on one synth (or on several
      ones, but no sequencer running), and then want a loop of what you
      just played to continue while you play the sax, and then switch
      back to your synth playing seamlessly...is that it?
      
      The way I get it, you wouldn't need any specific looping things -
      Ableton Live in its basic functionality should be good:
      have all the synths routed through live, either from your mixer's
      out, or via individual ins/tracks, and then those tracks routed to
      another track, which then is your "looping" track. Now set the
      monitor setting for that track to "auto", arm record on that
      track.
      
      When you play your synths, you should be able to hear them just
      nice. Now while playing, record a clip in Live on that very track.
      End the recording, and voila, via the monitor "auto" setting, you
      will no longer hear the synths, but the tracks you just recorded.
      If you then stop the track, you will again hear your synths. Makes
      sense?

Hi Per,
      
      Thanks so much for getting back to me!
      
      The KRONOS is my midiclock master at the moment as it drives the Waldorf Q,
      Pulse+ and the Andromedas midi clocks
      for syncing LFOs and sequencers/arps
      etc. However I will certainly read through your email to digest your info in greater
      reference
      tonight and ping you back real soon hopefully with some progress!
      
      Yes! Logic is crap with midiclock! and in fact I have dropped it
      only recently using Ableton instead
      if only for live performance use! I will look at Ableton, Mobius and SooperLooper for a solution!
      I only tend to use Ableton for triggering long drum backing tracks
      or (at the moment pending a looping solution!) full instrumental
      middle 8 soloing sections that I trigger from one shot keyboard
      triggers when I want to solo on the sax.
      
      I have managed to sort half my live set out and failing finding a solution immediately to the looping I can always play less intricate versions of some of my material for the
      giggs I have imminently !
      
      However it is something I must
overcome. The main thing is that for a keyboard player I need to be able to record the loop without having to think about it 
in terms of timing on stage, thats why the punch in/out and immediate playback has to be quantised to midi clock. I find the SoftStep has great functionallity but lacks the physical feel of something
       like the Behringer unit for example (F1010 is it?). I have 2 sustain, one switch and 2 EV5 volume pedals at my feet already and whenever 
      I have to hit a pad on the SoftStep to kick out say an
        arpeggiator coming from the Waldorf Q, in the heat of a
        performance I have to look down to watch my footwork
        : unfortunately the SoftStep
        wasnt designed for keyboard players! Your instruction re the quantise by bar
        in Ableton for 
      recording the loop makes easy sense. I think it will be the muting or the halting/resuming of the original sounds that may prove a little tricky to accomplish!
        I have had digital desks in the past and they all sound rubbish
        compared to analog. There are a few older analog racks that have
        midi muting on them- that may be a solution. However I think the
        best plan is to look at halting the background sound rather that
        trying to mute it while the loop is being played. 
        
I have actually only just moved with all my studio kit to Nimes and as my studio business is somewhat in the air at the moment (hoping to resurrect 
RIVERSONIC STUDIOS somewhere
        in the South Of France) I decided to go out on the road for the
        next year or so with my music. I have a big filmatic sound live:
        trouble is to get that sound one has to port a fair amount of
        hardware and then find a way to keep its sonic potential under a
        leash with only one pair of hands and feet!
        
        
        Thanks again for your response, forgive me if mine has been
          slow but I am still settling in here and have yet to sort my
          home internet connection etc!
