Good idea, added it.

Added the piano roll (shift P switches between sequencer and piano roll). You can edit the samples notes, but also all of the available automations. Additionally you can set project wide automations here like BPM.
Added initial synthesis work. Square/Saw/Sine/Triangle, basic ASDR controls.
Also added filters, and filter controls for automating (hp/lp/bp/notch, cutoff, resonance)
