Tool for making quick "audio memos"? Like Apple's Voice Notes, but for midi

In the past, I’ve used the voice notes app on my iPhone to record melodies or sounds when goofing around on my guitar or in the car. Now that I have a midi keyboard, when I’m playing around with new VSTs, I’m finding little beats that I want to record, but I don’t want to make a whole project file for them. Is there a feature or third-party app that I can download on my desktop that behaves like voice notes? I want something simple and clean to keep them organized and easily accessible.

Nothing specific. But if you search in the Apple Store for “midi recorder” I’m sure you’ll get a bunch of apps.

Does your keyboard synth have a quick MIDI recording/storage function so you can send it over to Cubase at a later more convenient time?
