I have had a Roland Juno 6, which was in fact a Juno 60 without memory. I created a special sheet with all the parameters of the Juno 6. I had to estimate the value of each parameter and "saved" those estimates settings in that sheet and "recall" them from that sheet whenever I needed a certain sound. I would have liked to have even some kind off a display.....
Good times, I did something similar whenever I ran into a nice sound on patchless devices. I'm pretty sure I had pages of 909 bass drum settings. These days it's simple: I record a few bars for reference, then take a picture of the knobs and save it in my project folder.
