Yes I know you can make steps now on the automation trac, but a real&easy step sequencer mode for the automation track with steps like inside the arpeggiator (note FX), which shloud have a smooth control and a subdivision setting.
Why?
A step sequencer is a common modulator inside synthesizer and effects. Yes, now you can create something like steps on the automation lanes, but it is faster and more easy to have a real step mode which you can add, delete and change the intensity of single steps with just one click and if you want to change the the subdivision of a specific range, just select it and choose your subdivision in a sub menu! The smooth value and subdiviosn of a step sequencer automation event is shown on the automation event (another cool feature I suggested)
