The XW synth is to much for some reason I'm more behind this synth then the other ones I have. The annoying thing is access time when I need it at inspired moments. 1 : Its to BIG to carry around it wont fit in my bag. 2 : I need a XW at the form factor size of an SA. 3 : It must be compatible with its bigger brethren. 4 : It must have SD cart I don't mind if it can do only two step sequence patterns. 5 : Similar performance mode every function the XW-G1 has include multi-key 6 : One sample bank suffice as long it has max lenght 16 bt Norm-At mode
