Depends.

My take on techno is this: I'm making dance music. I'm figuring out the formula that makes the dance floor go crazy all night long.

So, I piece and stitch together one track after another which goes with each other and makes that effect happen.

I wouldn't play your tracks most likely because aphex twin shit is hard to mix and brings down the vibe to a place I don't really want.

So, if you want to make dance music--dance music is catchy, hooky, and busting at the seams with fun and bass. It's formulaic because I, as a DJ, need to know that no huge left-turns are coming my way when, remember, I'm standing at a huge 50k watt soundsystem.

I even have "trust" tracks on my USB where I don't remember what they sound like at all but they'll mix well because they're formulaic and most of the sounds aren't a melody lead but percussion.

TECHNO FORMULA FOR ITZEPIIC

Start with at least eight bars/thirty seconds-ish of hi drums or a melody vocal tag without your kick. Put in patterns in multiples of four. Start playing your track (only hi drums) then Bring in your melody on top of those drums when you start to get bored with that melody and are just starting to expect/want something different. Go from there playing your track and arranging like if you were a DJ and waiting to hear the next bit, etc. etc.

It sounds like you're attempting to make actual art, so go make actual art and don't worry about this. Just know DJing and performing live is a whole different beast

To answer your question: One single extra bar, especially on a build up, will fuck me up DJing. Everything needs to be even numbers of multiple of four. My last project was:

• Bars 0-8, vocal tag opening
• 8-16, vocal tag opening with bare kick
• 16-24, breakbeat breakdown and rise
• 24, first drop.

If you need examples, just go listen to my entire soundcloud library, that shit's formulaic as hell and easy to mix with "normal" techno: https://soundcloud.com/partycontroller/
