This is could have been a great IDEA but at the moment it is just a missed opportunity .
it is not a groove box because is not performative like a groove box and the step sequencer is a disaster far more primitive even compared to the groove boxes of the 90s
you can not record live unquantised sequences ,
you can not perform basic features like note repeat ,
there is no swing ,
there are massive bugs on time stratching, launching clips is a total disaster only clips that are perfectly 1 bar l, 2 bar etc long will play in time ,
Black Box will not detect automatically the pitch of a sample and everything that is not in C will be distributed wrongly through the octave of the keyboard , so you will need to put only samples that are in C differently it will be a nightmare tuning everything in than saving on a PC than bringing it back to the blackbox , the company doesn't have a customer service , the customer service is managed by avarage users of the forum that very often answer without having tested the issues .
to reassume at the moment with so many bugs and the lack of basic features this is just another amateur bedroom fun device not a professional one, may be a firmware upgrade can fix the issues but I m not sure the company behind is interested to do that!
