I mainly remember being frustrated as hell at having no easy way to create a simple fill, or slight variation on the beat.
Then I started sequencing my own beats from an Atari, first with a borrowed Alesis D4 drum module, then with a borrowed S950 sampler, then I eventually got myself a Yamaha A3000 of my own.. I found I was really struggling to create good grooves just by programming MIDI with single hits.. the problem was, curing it by using a prefab loop really did now feel like cheating to hide my own deficiencies.
These days I either program my beats, use loops I made or recorded myself, or a mixture of both, and there is no question that maybe all the magic of the track might come from someone elses work.
Not to say that I despise people who use loops, just that I have extra respect for people who are capable of making everything from scratch..
