I’m planning to buy the OP-1 but the lack of velocity sensitivity is a bummer. I plan to side step this by using a small midi keyboard with drum pads.
From what I have read, it seems that you need a usb midi host. These need to be plugged in. This defeats the purpose of having a portable system. Is there a way to use a battery? What is the most compact portable setup? MidiGal? Thank you.
