a friend over in the states just added midi on his sounds ok. Have to say was a bit bored after twiddling it for 10 mins, and i find the interface quite laughable it is like it has been made for a child, judging by the size of the keys and pots. Think they could have gone to town on the construction and put lots of leds on and made the pots better. But at least they bothered good to see one of the big companies still keeping their ear to the ground. The filter is probably the best thing about it and has an input so is useful, sure some good mods will come out to haven't had time to try yet. I think the gakken looks better and is actually better on some fronts though that has big draw backs also but at least it has an envelope.
edit: i tried to add cv/gate last night, cv seems to work alright, goes strange when you add the gate signal, would be interested to hear others experiments. No low notes when gate is added, didn't have much time to fanny about with it, have to say the build quality is very flimsy and it is not much of a pleasure to work on because it is too small. Pitch, gate and cutoff are marked on pcb.
