HI ALL,

been a minute since checking in , Luka - I owe you an email after your incredibly kind and thoughtful email last year ! sorry got caught up on the road and learning a ton, but happy to report since switching to art-net , beam has been batting 1000. and thank you for everything.

had a couple Qs but figured id break em up by topic in case that helps someone else later on -

I have found a work flow with some of my diy led fixtures which has me wishing for a cascading or sequential Beam Device assignment feature. for example, even just a 6x6 rgb led matrix fixture, i like running in 108 channel mode [r , g, & b per pixel] - that requires assigning 36 par devices each fixture, or 108 for my 3 parallel panels that i arrange as one ‘display’. I remember when Ableton added the “map to siblings” function for macros , and maybe there is a way to add to the max patch , havent tried that yet but figured i would ask if there is a clever work around to patching assigning a large amount of items to Beam m4L devices in sequence.

to be clear my purpose is to have independent color control per pixel . clicking down each menu is prohibitive when you realize a mapping is upside down or inside out [hightly recommend the max 4 live note remapper as a band aid - or a quick python script to rearrange tag and note mapping of sbf ‘s after swapping file types to json] so maybe there is a better way to do this , to have , basically, an extrmemly low resolution display? or maybe some kind of videosync x beam patch with a fixture as a video output?

thanks for your time and hope all is well , will post a related fixture profile q in new topic
