Thanks for the information.
I was a little bit confused about the Roland does not accept Midi sequences, what do you mean?
For instance I have a similar issue with my live show, I play the keys and would like to be able to play/trigger sequence like a drum beat or a short melody while I play and let it play continuously until I tap it to stop.
Can I do this, if I have wav files? Like here is one of my tracks that I would like to play live, there are many layers and in order to do so I need to trigger them at the right moment.
Would really help if the Roland is the best sampler for me?
