My experience with the knobs is that they can be jumpy. This can make sequencing a bit frustrating at times. The knobs have a soft "click" as you turn them so that, in theory, you can adjust the note values by one semitone at a time. However, this movement is not 100% reliable - sometimes I rotate the knob by one "click" and the note jumps by 2 or 3 semitones. I've found that I have to watch my MIDI data in Logic to be sure I'm dialing in what I intended, unless I'm merely looking for a happy accident.
I just received my Beatstep. Great construction quality, pads, knobs, everything.
I have just used it to step sequence some plugins and it works great (as advertised)
BUT, as jsmirk said, knob movement is not 100% reliable when adjusting note values.
At first I thought that there was a scale selected, but no, it was skipping some semitones in chromatic scale.
If I selected major scale it could skip 2 scale notes AND MORE !
Sometimes it even played two notes when changing notes.
What I noticed is that to not skip notes I had to be very careful when rotating the knob.
You have to make the click turn very softly.
I haven't updated the firmware yet.
I assigned knob 1 to a filter and I had to turn the knob at least 3 times to get the full effect.
That doesn't seem too good if I want to do a smooth filter sweep.
Ok, I just checked knob 1 in ableton live and I had to turn at least 3 times to pickup the
control and then change the parameter. That doesn't feel normal.
I haven't detected any jumping of parameters in ableton
just the skipping of notes in sequencer mode.
UPDATE: The Beatstep gets out of sync in Ableton when I begin to change from 1/16 to 1/4 or 1/8.
