[chuck-users] ChuckSound usage

Paul Batchelor mentioned this in a recent thread; it's a chugin that allows for the use of csound instruments inside chucK. his article about it is here: http://csoundjournal.com/issue21/chuck_sound.html and it can be picked up here: https://github.com/PaulBatchelor/ChuckSound . A question that came up in the course of using it: If I use one csd file containing several instruments (and some global set-up instructions in the header section) can I use one shred to play multiple notes on multiple csound instruments in that file simultaneously? -- or do I need multiple shreds? -- and can they share the same header global variables?
