I also advise you to use the
KeyStep. (I assume you do not need CV controlled polyphony...)
It is a great polyphonic sequencer with the real time recording very quick and intuitive. No programming needed when using that feature and you (can) get a loooot of happy accidents, if you want. Worst case, you use the MIDI editor to program notes exactly as you want quickly, similar to any DAW/Seq. It does involve your PC but is fairly easy and straightforward, if you have an exact idea and you are not that good playing it in real time.
Also the weighting and aftertouch responses (and feels) are surprisingly good compared to most MIDI keyboards up to a couple of hundreds of euros. At first the keys seemed a bit too small to me (got big hands so it looks like a toy, when I play it
) but I must say after using it for a while - the size is just perfect and I can hav it in front of me on the table just next to my BSP
Not to forget: you get the KeySteps for about half the price of the BSP...
