Thanks everyone for your comments and help.

If I sum up my alternatives to a swithc AR/MD:
[ul]
[li]Octatrack: Hell no! :imp: Sorry but it is not for me. I had one and it was not a good experience…[/li]
[li]Beatstep: I had one as well. Cool for sequencing but you can’t save the sequences or really do advanced sequencing…[/li]
[li]Ipad: I have an old one, first generation, as said before, I am afraid that it will be buggy and unreliable. Besides, it is very close to a laptop…[/li]
[li]Cirklon or midibox: that would be good but big and difficult to get.[/li]
[li]An old RM1X or Electribe: why not…not excited about it :joy: [/li]
[li]MPC: probably the best option and value. advanced sequencing and more samples capabilities[/li]
[li]Trigger Finger Pro: My last discovery. It looks cool but it is a new product so there is not so much feedback or video online. It seems that the sequencer is less powerful than a MPC.[/li]
[li]Design my own sequencer with Arduino solution. Time consuming and distract me from the musical composition…[/li]
[/ul]

Where is the magical solution? :joy:
