Please forgive me for my honesty in this long reply but you’re stressing over nothing and I’ll tell you why and will tell you how to resolve your issue!
I’ve listened very carefully to your two samples and it may shock you to know that a basic 1 bar drum loop does not make a hit record.
Once you’ve produced, mixed and mastered the full production I can assure you that no one in their right mind will hear a ‘tonal thwack’ on the drums and if it’s an incredible song I can also assure you it won’t be rejected by radio stations, etc because they are not listening out for a tonal thwack but how the entire song blows them away!
I’m old skool and have been a very successful professional keyboards player/record producer/composer for nearly 4 decades and if I come across a production issue I find a workaround and I recommend you take these steps:
Slice up the original loop and drag it ( on to the bottom three blocks) in Groove Agent. You will then have each drum sound over the keyboard so you can simply play the rhythm into Cubase yourself. (It’s such a simple 1 bar phrase - a monkey could play it with his hands tied behind his back!) You can then create new and interesting rhythm variations for different sections to take the listener on a journey like all good songs should! You will also have complete control over each individual drum sound which can be enhanced in hundreds of ways.
If you can’t be bothered to do all that simply find a new (and possibly better) loop at your songs correct tempo so you don’t need to time stretch it or simply choose preset kits from Groove Agent (or any other drum machine VST’s you may have) or use individual 1 shot hit samples and construct your own mega kit!
I hope you can now see that you’re concentrating on a speck of dust rather than seeing the bigger picture?
It took me quite a few years into my career to realise that the general listener on the street doesn’t hear what we hear. I was beating myself up unnecessarily because I couldn’t get my productions to sound the way I wanted them to but it doesn’t matter because the truth is the general public are either touched by the whole picture or not and don’t forget that most people listen to a 128kbps mp3 file on laptop speakers so definitely won’t hear your tonal thwack!
You may be saying to yourself who does this guy think he is trying to convince me not to be angry with Steinberg for including an algorithm that is not perfect in every way - well forgive me for blowing my own trumpet but I’ve had 18 #1’s in 37 charts all around the world, have won many awards, was signed to Sony Records and have had my own production company since 1989 composing/performing and producing music for singers/songwriters.
Most importantly you may be interested to know that all the music to those 18 #1’s were composed, performed, produced, mixed and mastered by me in my studio using either Cubase 5 (or a lower version) as I’ve only recently upgraded to Cubase 8.5. I used Cubase 5’s inferior timestretching and pitch shifting algorithm all the time and it didn’t stop me from getting so many #1’s and my music played daily all around the world!
Sorry for the length of my reply but I hope it has given you and everyone else food for thought?
Have a nice day!
