I've been mapping various transitions to individual pads on my APC40 which has allowed me to cycle through transitions whilst in longer mixes. When playing back the recordings, the effect looks even better than I thought it would. It'd be great to be able to do this automatically somehow, like with a transition sequencer. All that would need to be done is giving us the option of choosing Transition FX or Channel FX when deciding what FX to use for the sequencer.
