There will often be days when you lack inspiration and creativity is long gone. That's when you pull a trick out of the hat. This is one of them. By setting your synth up for a "Negative Pitch Follow" you will reverse your keys so that the highest note will be at the bottom of the keys and the highest note will be at the top. Now try to play a few chords. Not so easy is it? Everything is in reverse and the usual chords are not possible to play using the finger settings you're used too.
I do this occasionally and it's always very rewarding. Try sequencing some stuff by playing reversed. Then reset the pitch on your synth and play back the sequence. Maybe that's your next big hit! :)
I'm using the Roland D-550 here. On that it's easy to change the pitch key follow. Not all synths has this ability, but check out the ones you have. It might be easier in software where you can use a MIDI plugin to get this done regardless of the synth plug you're using.
