Recall Sheets allows to save patches for your analog synthesizers. Now, you no longer need to manually redraw the instrument’s settings. You can export a ready patch as an image or send it from the application for printing. Within the same device, patches are conveniently located as stickers. Every card shows the patch name, date it was created and sound type (for example, bass, pad, fx). You can do search not only by patch name but also by sound type. The sound editing screen allows you to change the scale of the synthesizer’s interface. You can also add a comment to your patch.
