Feature requests - record add notes without replace the notes (overdub)

[mirko]

Hi, I need for my live dj set that Keystep in slave sync mode by my master ext midi clock, so I can put in a empty 16/64 step sequence my notes, after overdub this sequence add notes (merge new notes with old) without replace the old notes. No I need to add notes at the end of sequence, is a useless function for me  . This is important for sequencing a drum machine or Akai sampler, recording a kick, after add a clap...hit hat etc 
Thanks

this would be an excellent feature, but also the opposite could be useful: if recording notes would replace all pre-existing notes on the same step. I assumed this is the default behavior, but when I recorded notes while the sequence was playing, some old notes still remained in the sequence even though I was holding down some keys during the whole sequence duration. Maybe I was doing something wrong, I'll try again later.
