crow m4l: ^^outs: lfo sometimes crashes Max + Live

[dndrks]

the LFO section is the most complicated, because at the time of release crow's LFO function was not syncing -- it would drift quite a bit, making accurate timing impossible. to compromise, I made an ASL action that represented an LFO which would be retriggered every bar. this was necessary at launch, but (hopefully) is needlessly complicated these days -- either way, it causes crashes:

• Max is experiencing Lua crashes
• if you do not select an output before selecting the LFO action, Max will crash
• if you do select an output, you can load the LFO page, but then changing the LFO rate will crash Max
• no other action is experiencing this trouble
