Hi,

If you already know how many trials you will have of each type, I would probably use the pick function, like this:

N_SEP = 4;
N_STIM = 8;

stims = randomize("theStimuli")
seps = randomize("theSeparator")

subseq = []
for (let i=0; i<N_STIM; i += N_STIM/N_SEP) {
  subseq.push( pick(stims, N_STIM/N_SEP) )
  subseq.push( pick(seps, 1) )
}

Sequence( "intro" , ...subseq , "end" )
