It is suggested that you include drums to give the bass context. You can also add leads, or intros to give it more context if you like. Mixing drums and other sounds is also an important part of creating bass drops, so feedback should be given to the audio clip as a whole. Bass drops don't have to be dub-step specific, use any genre you please.
I just recently started taking synth design seriously, and it's definitely a great way to make sounds that are fresh, as well as get just the sound you are looking for, as opposed to browsing presets.
IMPORTANT NOTICE
Due to this thread going off on a tangent, and not being focused enough, I'm introducing a few more rules. They are as followed.
RULES
1. It is required that you give constructive feedback if you intend to post a clip. This is to prevent too many people from posting clips without contributing.
2. Unless it is relevant to the discussion of sound design, or you are posting a clip and giving feedback, please do not post anything. We want to minimize clutter.
3. Please take criticism respectfully. This thread is for synth design practice and feedback, not for defending your work.
4. Using number ratings is not necessary, or useful for that matter. Rate My Wubs is just a catchy name XD!
5. Please use the following format to post feedback and post your work (minus the quote tags). This way it is easy to identify topic specific posts. Also, please do not use quotes, it takes up too much space and it isn't very neat. Just refer to artists by name.
@ArtistNameHere: Feedback for their most recent post.
@ArtistNameHere2: If giving feedback for more then one artist in one post.
If there is anything you want to say about your sound clip before people listen to it, put it here.
Link to your sound clip. Use any sound streaming service of your choice, such as soundcloud, or drop box.
After your done posting feedback and a clip to your post, the rest of your post can be used for miscellaneous discussion. Keep feedback and links to your sound clip on top so it is the first thing people see.
I'll get us started, here's something I made with Massive, it's my first attempt. I threw in a drum loop and slapped soundgoodizer on it XD! I also automated the LFO.
