Hi Imali,

I am not sure whether I understand completely what you want. I guess you want to simulate time series of 'sources', that have different (more or less well defined) spectral characteristics.
As of yet, ft_connectivitysimulation does not support this. 

You could however call ft_connectivitysimulation twice, (using cfg.method = 'inear_mix') and using different cfg.bpfreq each time. Subsequently, you could sum the resulting time courses:

for k = 1:numel(data1.trial)
  data1.trial{k} = data1.trial{k} + data2.trial{k};

where data1 and data2 are the output to ft_connectivitysimulation.
