Every music producer has problems one time or another when it comes to producing music, they may not be able to find the drum kit to go with the other sounds in the beat or the right baseline to go with the beat etc. Don’t worry about it, you have to just keep trying and finding the correct sounds. You could have problems with loading samples or even cutting samples up to make a remix or anything.
If you’re having problems with producing music the best advice is to learn from somebody else, and you will properly learn more than your expected because they will properly know something you don’t and you could exchange information. Producers learning from other producers is the best experience of learning how to produce music because learning from a boring textbook isn’t exactly going to show you how to do something. A text book in music production is great if for example you want to learn what a compressor does, or a limiter with diagrams. However if you want to learn something so practical, it’s best to learn from another producer.
Music producer problems arise everyday, but if you want to have a basic setup in your home studio that can lead to great results I would recommend you get a PC, Midi keyboard, Microphone, Monitors and an Audio Interface. Just with these few basic pieces of equipment a lot of problems can be resolved and you could be producing great quality music from home.
