My MiniBrute 2S arrived this afternoon, along with a RackBrute 3U. The whole thing is a bit overwhelming and I expect to be learning this for a long time. Before ordering the 2S, I assumed it would be possible to connect a MIDI keyboard. Now I realise I don't know if this is possible, or if it is, how it is done. I have an Akai keyboard with a USB-B socket and no other connections. Can this be used with the 2S? I assume at the very least, I will need to adaptor or other.
