I listened during lunch - it is a nice sounding little device.
what are the specs?
number of voices, polyphony, etc.
Total of 16 unique patterns, which can be in a sequence of 100 orders.
A pattern consists out of 4 drum sounds which are shared over each pattern, and 2 synths, which are unique to each pattern.
In total there are 6 sounds that can be played together, of which the 4 drums will sound the same over the entire song.
Each drum sound can have its own FX, and on top of that, the entire song can also have an FX which can be set to either one or both of the synths, the drums or all.
A pattern consists out of 16 bars, which can be decreased if desired.
Tempo can also be changed.
As for polyphony, there's none. A sound plays until the next is reached, no matter what, but as you can play all the 6 sounds together, there are some ways to emulate polyphony.
