Do You know some good sequencers which works instead of hardware midi keyboard or with midi keyboard like Ableton arpeggiator (midi effect)?
Standalone or vst or midi effect vst?
I'm looking for something like sequencer in Steinberg Retrologue 2 or DiscoDSP Corona.
Ability to control number of steps, velocity and pitch values on each step controlled by sliders and more advanced stuff like chord mode, triggering by note, lfo, mod control etc.

I completely forgot about this little monster

 

Kirnu Cream is very powerful, though I heard it's badly maintained when it comes to bugs. Cthulu is a classic.

Besides them, other very powerful sequencer plugins are:
- HY-Plugins: haven't tested yet
- Sugar Bytes Thesys: tried but man, it's crazily complex

- MidiMood Kamaleono: not exactly an step sequencer but extremely powerful. This may be a very underrated gem
