Oneshot sample playback module mutes with red mark on the circuit graphic after table saved, app closed and rebooted. I use the Nexus 7 with Android 4.2.2. I've discovered a "workaround" to this problem. After double tapping on the muted module to access the Subtypes window, I tap the Loop Player, hear the sound that is loaded in the Oneshot and then tap Oneshot. This operation unmutes the Oneshot play back module. The module will remain functional as long as I don't optimize my OS or turn tablet off and reboot. The "workaround" is consistently effective but it would be nice not to have to use it. The Oneshots capicity for speed change both foward and backward is very usefull for manipulating field recordings. Hope you can fix this little glich. Great app, Thank you.
