I posted this in another thread recently, but “patching backwards” can be fun - start with a cable plugged into your output jack and work from there. Any time you want to make a new connection start with the destination jack and then decide where to source voltage from for that jack. Imagine constructing the entire patch diagram from the output and moving upstream, rather than starting from the original CV/signal generators and moving downstream.
Another useful exercise: give yourself a short time limit to build a patch and play with it. Don’t record anything you do! Focus purely on exploration without the pressure of recording/“creating” something good. Tear it down immediately when you are done, to emphasize the ephemeral nature of the exercise. Or hey, if you really love it, then keep working on it! Maybe see what the craziest noisiest thing you can get going in 10 minutes is, play with it for 10 minutes, and then totally deconstruct it and re-initialize everything. Maybe you have a more specific goal: set up a basic rhythm, lead, and atmosphere voices in 10 minutes. Jam with it for 10, and then deconstruct and start over. The general idea is to give yourself small challenges or goals and to work in a manner where you are not necessarily interested in the final output, and giving yourself freedom to explore in a controlled/educational fashion in a non-judgmental way.
Another exercise: pick a module that you normally use in one manner, and try building a patch around it that is totally different to how you normally like to use it. For instance, use your clock divider for generating subharmonics rather than clock divisions. Use your Slew Limiter as an envelope generator rather than for portamento. Use a s+h for sample rate reduction instead of CV sampling. Etc.
This thread has some really good ideas - there are others like it on lines and elsewhere too!
