I would really love to see in sequential synths what roland calls AUTO.
This means, without external midi clock you can use your synth as master, e.g. start/stop sequencer, set bpm, etc. As soon as external midi clock detected synth goes to slave mode.
In particular I find this very useful, if you just want to play with a synth a little.. It is quite annoying to go to Globals and change settings every time.
