The “auto grow” feature for live recording in Drambo 2.0 is great. I wish it would be available for step recording as well. Enter as many steps as you like without thinking about sequence length. Many hardware sequencers work that way.
Though the step sequencer doesn't have autogrow you can
set the length of a Clip before hand using the icon next to the Rec button.
Press Record without pressing Play and then you can input whatever notes you like
using either the onscreen keyboard or an external midi controller.
Step sequencer autogrow would be an interesting feature.
