Melody delay in triplets

    Hi, I'm trying to program a sequence for a song which has a triplet feel using tap tempo to sync a 3 note pattern using the melody delay. The tempo of the song is such that tapping each triplet beat is too fast for me to do reliably. What I'd really like to do is tap each beat and have the melody delay play the notes as triplets, but the settings are such that you can only divide a crochet by 4 - at least as far as i can see. Anybody got any ideas for how I can crack this please?? Thanks in advance!!
