Hello everyone, as mentioned in the presentation I published this morning, I play on an acoustic accordion (so WITHOUT MIDI). However, I'm thinking of buying a Ketron SD40 (or something else if someone has a better idea!) and I'll explain: on the one hand, I'd like to be able to use midifiles (midi files) that I have in my computer and so far, I think that, even without being connected to MIDI, it's quite possible. But, on the other hand, I have a whole repertoire composed of pieces for which I don't have midi or Mp3 files. Therefore, in this last case, I would like to know if the SD40 (or other), without any MIDI connection, could be used as a "rhythm box" and this, in all the musette oriented styles, such as waltz, march, tango, bolero, paso, cha cha, samba, polka, etc...? If so, could you explain to me the manoeuvres to be carried out on the machine to reach it. In advance, many thanks to all of you.
