Yeah, it's easy to make fun of someone, but in fact you are the biggest fool. There is no stupid questions, only stupid answers, and your's are in the league.
Don't take it to heart. As a noob you get a pass to ask all kinds of questions without it actually reflecting negatively upon you at all, like no one is going to think you are stupid for asking a noob question even though we might see some humor in it....by that I mean just because we might see some humor in something you said that doesn't mean we are actually laughing at you. We have all been there, asking them noob questions which get the gas face, don't worry about it, just keep on asking away.
If you had asked the same question a few years back I would have said Propellerhead Reason fit's the bill, but it has since acquired audio recording capabilities....but almost everything has that ability these days, but you don't have to use it, like I can totally fire up Cubase and load up nothing but MIDI tracks if I want too, so if you looked at my project there wouldn't be any audio tracks at all.....but of course all the menu items for the features you don't use will still be there, not such a big problem as they are usually structured as, MIDI, Audio, Score, etc so you just ignore the menus you don't use, in Cubase you can even hide some of the things you don't want to deal with, which just leaves the keyboard shortcuts, which can be customized to streamline MIDI functions.
Reason is still worth considering if you want something reasonably minimal, like you pretty much have to work with what they give you, loading what you want into the rack......all the routing possibilities are still there but the configuration is that of an old school hardware rack, Live and FL Studio are more configurable, FL Studio has cornered the market by streamlining mouse based composition for noobs who start off without a more efficient MIDI controller, and that's something I think you should look into first, because companies often bundle software with MIDI controllers which may well provide a cheaper upgrade path to the full software than buying the full version outright......you need to research it though, because shit changes from time to time.
