loadbang is called in both MAX and M4L when he patch loads and so can be used to init the patch, but you may not be able to call M4L Apis at this point as it may not have initialised. live.thisdevice lets you know when the M4L Apis are ready to be called.

LOL what a newbie...I am hehehe

much appreciate it = ) thank you!! I missunderstood the concept of it = ) = )

Lee, the way i understand you is, that it is recommended to use BOTH in an M4L device, which should still be usable outside the Live context? Thanx for clarification already :)

you could connect a [live.thisdevice] into every loadbang you use. These call call when the patch is loaded. you will probably get error messages though if you keep the loadbang. If you prefer no errors, you could have loadbang or live.thisdevice into a [send ---onloaded], then could choose sepending on max or M4L which you used.

From [live.thisdevice] reference file:

Used within Max, live.thisdevice functions essentially like the loadbang object. The middle and right outlets are inactive in this case.

So, if you are going to use an object in both Max and Live, just use [live.thisdevice], and do not use any [loadbang].
