I am currently seeking to adapt the "gated pacemaker" model of
Carpenter and Grossberg (1983) to a simulation of musical rhythm
perception (a bit speculative, I admit).  I have written a program
which models the dynamic behaviour of the neural circuit and
have been messing around with the parameters.  Unfortunately, my
program does not reproduce the linear relationship between the
oscillator period and the transmitter release rate parameter, C5, as
described in the above paper.

Has anyone else simulated and used this model and, if so, did the
parameters have the effect described?  In addition, has anyone tried
to synchronize the circuit's oscillations with some external rhythmic stimulus
of a given fixed period (within limits)? This is mentioned in one of
Grossberg's 1986 papers on serial order, masking fields, word
recognition etc. (I'm sorry I don't have the paper to hand).
