hi Ted,

thanks for adding this.

i don't know much about this, but is it ok to make an assumption like 
this? i mean we hardcode magic numbers that 24 pulses are 1 beat and 4 
beats are 1 bar.

it seems that you forgot to register the vector with the garbage 
collector that (midi-position) returns. check 
SchemeHelper::FloatsToScheme to see how it should be done, otherwise it 
leaks memory.

best,
gabor
