the more synth-isch Stylephone does not need that ball pen-thingy to play with. it has 2 oscillators – this video does not say what these pots really do or may do.. sequencer? synth edits? … but well, there is memory banks and it can sound like a synth..
370€ isn’t cheap at all, since there is a Microkorg or a small iPad you might want instead, so .. let’s try to watch and listen to more to come. anyway, could be fun?
