The cons:

1) Range for Higher Notes
-- The default range for the Mojopedals is C2 to C3. One can only shift up by 2 octaves, although if you do that and transpose up by 12 semitones, then you can effectively shift up by 3 octaves. As such, if you want to play very high notes (e.g. a high synth drone), then you may not be able to produce these high pitches, but this depends on the product that you are hooking up to.
2) Inability to select banks
-- One cannot use the Mojopedals (alone) to select MSB or LSB. One can only do Program Changes. As such, what I have found is that I cannot fully access General MIDI 2 tones, just the 128 General MIDI tones. This is the biggest drawback with the product, in my view.
3) Kind of heavy for a 13-note pedal keyboard at about 20lbs
4) The velocity sensitivity curve for the pedals is OK, but not great.
-- It can be hard to control the volume dynamics if you are trying to play softly.

The strengths:

1) Sturdy and rugged build
-- Both frame and pedals
2) Has a digital display
-- This makes it easy to tell which tone you are using, as well as which Channel you are transmitting through, how many octaves or notes you have transposed by, etc. I don't know of any other pedal keyboard that has a display, and I find this feature to be extremely useful and more user-friendly than pressing combinations of pedals and buttons to select what you want, and then having to remember what everything is set at.
3) Low Price
-- At least in the U.S., this is the second-cheapest new pedal keyboard that you can get at the time of writing, to my knowledge. And the only one that is cheaper has some significant design flaws, according to what I've read.
4) Polyphonic
-- That is, one can play and have sound out multiple notes at the same time. Very often, I play 5-chords (one note with each foot), but it is feasible to play Sus chords, too. Some other triads should be possible, too. Note: I do this while sitting down.
5) By shifting octaves/transposing down, one can play insanely low notes if one wants to.
6) Good (low) latency
7) Foot pedal spacing
-- From what I have read, the spacing between pedals appears to be similar to or larger than that for other pedal keyboards. For me, the spacing is wide enough that one avoids hitting two pedals at the same time by mistake, but also small enough that one can simultaneously play adjacent “white” keys using the same foot.
-- Note: I play either barefoot or using socks.

Overall, I'm very happy overall with the MojoPedals and would highly recommend them to anyone looking for a good basic pedal keyboard.
