in what thread does the "read" message operate. high or low priority thread.
i spoke to plogue bidule developers and it seems that bidule is fully capable of hosting vst plugins inside msp vst~ object. it allows to map its internal clock (of which there can be more instances) to be mapped to incomming midi data (even 14bit resolution) and then pass this information to plugins loaded inside bidule vst. if it works correctly with read/write fxp files, a fully modular vst environment within max is possible...egh:)
