Timer if no Signal: Please add a toggle and/or configuration possibility

[Maschine2501]

Hi there,
following the previous e-mail communication:
There iss actually a timer which shuts down the fifo stream if there is no sound for 5 seconds.

Please add a toggle (on/off) for the sleeptimer.
If possible with te possibility to set a custom sleep-timer time.

This would be great ;)

Regards,
Christoph
