you need to have lockfree access to the note sequence.
while still being able to manipulate it from the gui thread.
several approaches to achieve this are possible. and it depends a bit on
taste and the app to select them.
but the major part of complexity lies here.
I assume std::priority_queue can't be used, because it uses a
std::vector which will, under the covers, allocate memory from the
stack.
It would be interesting to try to write an STL queue-like container
with an allocator that grabbed chunks of memory from a pool in an
RT-safe way. Maybe via message-passing over a ringbuffer? Anyone
seen/have such a thing?
