Marbles in audio rate goes permanently silent when modulated with LFO

[espenstoro]

Windows 8.1 Pro x64 Rack 0.6.2b Connected via bridge to Cubase Pro 9.5 x64 at 44.1khz, 2048 buffer size.

How to reproduce: Marbles, latest update (outputs t1 and t3 connected to AS 8-channel mixer into Core Audio inputs 1-2), set to audio rate and maximum speed, default scale and clock settings. Modulate "rate" input with any LFO. When it goes way high, it goes completely silent with no blinking lights, and needs to be removed and re-added to output sound again, initialize won't work. As if the clocks just shut down entirely when it goes higher than it should (?) Got an instant "rack is not responding" crash the first time, but can't reproduce it.

Not sure if it's a bug, or the practical application of this method, but it's odd.
