I have big problems using Live 9 together with some M4L Devices and tempo changes. A Sampler playing back some midinotes plays just fine before and after a tempo ramp. During the ramp I listen to glitches and clicks. CPU goes up, too (significant change). I admit, that I often use CPU "heavy" sets, but the behavior starts at about 10% CPU, which should be absolutely no problem.
Maybe someone here experienced this, too? Or do you have any tips?
A strange thing is, that the glitches/noises aren't recorded, they only occur during playback.
I tested with 32/64 Bit release (9.0.6) and beta versions, with many different audio interfaces (internal, Firewire, USB) - but always the same.
Could you try the attached set to reproduce the behavior? I would be very thankful to know, if there is something wrong with my MBP/System (OSX10.8.5) or if it's a bug, which occurs also on other machines (I'm already in touch with cycling and Ableton support, but with ambiguous/unclear results).
Thank you, Martin
