Presets are stored in a file called "SlynthyPresets.plist" in the documents folder. This can be accessed through iTunes. You can export the list as a backup or import a different preset list from your computer.
Recording on Slynthy:
At any point press RECORD. The RECORD light will turn on and audio will be recorded to the file SlynthyRecording.wav.

After pasting into Slynthy you must press LOAD LAST REC to cue the audio for playback.
