I can't, but if you are more musically trained and/or more accomplished than I am YOU can.

As it turns out, you have already used the "upload audio" feature that I haven't yet used. And, as it turns out, you can play in a band to create audio to upload.

Which means you DO have musical training and skills that I lack. And, it means that you can utilize the Suno A.I. in ways I cannot. More importantly, you seem to be willing to share what you know and listen to others. THAT is the truly rare skill.

There are things I've been able to do with my limited skill set because I worked really hard and long to figure out how other people were able to manipulate the software to achieve incredible results. That involved a couple hundred hours of listening and evaluating the setups. Here is the point I'm making. Someone with YOUR skillset could do truly incredible things compared to what I've been able to accomplish. I'd be happy to explain how.

1. The many hours of listening I mentioned is integral to using Suno in my opinion. Hearing what others are able to do, and (as importantly) HOW they did it is a step that can't be skipped if you want to get out of the "hit or miss" situation you mentioned.
2. With your skills, you can write partial instrumentals and upload them to get numerous ideas that you can pick and choose from. You can then put the best ideas together with real instruments and get something that is entirely yours, but that you used a tool for. I suspect you're already uploading, so this is easy for you.
3. Invest some time listening to the available genres available. I have found one (Illbient Afrikaner Folk) that moderates Southern Rock, Rock, Country, Celtic, Classical etc. I seldom don't use it. If I hadn't invested a couple of hours listening to hundreds of genre selections, I'd have never have found it.
4. Notice that the next generation improvement is going to include converting to MIDI. That will be huge for me. I'll be able to dis-assemble and re-assemble any of my songs and shorten, lengthen, change sequence and so many other things. I presume you can play instruments and record in MIDI already.
5. Notice that I keep talking about investments. Investments of time primarily. There is no substitute. If you are to make the best use of your skillset, investing time is of the utmost importance. Nothing good comes easy.
6. Listening to what you've already posted, you are obviously skilled at selecting instrumentation. Suno lets you make multiple copies and play with different instrumentation packages. It won't (imo) end up better, but it will get there quicker in most cases.
7. If you want me to, I can direct you to some users on Suno who have done some particularly impressive things. I've discussed with them how they did that. With some, it's just dumb luck. With some, it's hard work. With some, it's an impressive skillset in musical knowledge that allows them to do what I cannot do - provide detailed note by note, chord by chord, or measure by measure information. I suspect you could do that as well as they do.

I think you've already figured this out, but my whole point is that your outcomes are heavily affected by your investments. If you're not getting much out of Artificial Intelligence and you've invested a lot of time and effort into learning it and using it, that would be disappointing. But if you're not getting much out of it, and you've not invested much into it, that's a whole different problem. You seem to have grasped that, but some have not.
