If you get stuck, creatively, create artificial boundaries, perhaps by recording an entire album with only one instrument, or by recklessly erasing all the presets in all your gear, forcing you to start from scratch with only a few sounds of your own design. Creativity comes from breaking boundaries, and all boundaries are self-imposed, so once you create a limited vocabulary you will find yourself starting to break out if it, expanding into new techniques. Also, make decisions as you go, rather than defering all the decisions until mixdown. It's better to make a mistake that forces you to think, than it is to wander around aimlessly without any concrete vision. These suggestions run opposite to the trends in modern studio gear, which derive from companies trying to sell you stuff you don't need by instilling the fantasy of total control.
Total control is often counterproductive.
There is no substitute for listening, not only to your own work during composition but to the sound and energy of other's. Also, get to know your equipment and really push it to it's limits - it is better to use a small set up to maximum effect than to use an extensive set up to minimal effect. Providing you have enough technical knowlege of the equipment you use then the rest should follow. If you feel creatively dry, conceive a new interface, or impose a new set of constraints, or do something else that effects a paradigm shift. Try playing first, and then thinking later as a maxim is a good one.
