I will definitely choose a mode depending on how I want the track to feel. What I've noticed is that most genres of electronic music stick to the regular Major (Ionian) and Minor (Aeolian) modes. The Minor mode can also be written in Harmonic or Melodic Minor, Harmonic Minor is that classic Armada records sound, with the progression ending on a chord containing the raised 7th and I find that Harmonic can provide some interesting tension.

Now, since you've brought up modes I'm assuming you know there are 7 main modes, Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian. All these modes definitely have an individual feeling, for example Lydian mode can have an uplifting feeling to it (since it is a variation on the major scale) without sounding cheesy. Dorian mode is a variation on the Minor scale and can have a slightly more energetic, less depressing sound when compared with the regular Minor scale. Both Lydian and Dorian modes have been heavily used in a lot of progressive trance within the past couple years. The Phrygian mode is probably one of my favourites, if you're going for a more Middle Eastern vibe this is the mode you want, it has an exotic sound to it while still managing to sound complete. What I've found through simple trial and error is that pretty much every mode works for electronic music except for Locrian and Mixolydian. Mixolydian can be made to work for a melody and can sound cool at times, but I would never suggest creating a Mixolydian chord progression for your track, I feel like it sounds like shit but to each their own. The Locrian mode is my least favourite because it just sounds unfinished when you play it, which probably has something to do with it starting and ending on the 7th note of the major scale.

So, in conclusion there are 5 modes which IMO work well for dance/electronic music;

• Ionian (Major) - Happy, Cheesy at times
• Aeolian (Minor) - Dark, Most common mode in dance music
• Dorian - Dark-ish, Higher energy than Minor, Slightly happier than Minor
• Lydian - Uplifting, Happy (less so than Major), Energetic (My personal favourite mode)
• Phrygian - Exotic, Middle eastern vibe

Hope this helps 

Probably one of my favourite JP8000/8080 imitations http://shop.cfa-sound.com/products/super-7-supersaw-vst/

If you're looking for that classic supersaw sound, this is probably the best thing for it.

only thing id say that hasnt been said already is that the autopan is a little bit much

Agreed, the auto pan is taking away from this track, it's a bit distracting at times. But this sounds fucking awesome.

I prefer to work with straight audio samples being dropped onto the grid in ableton. I'll find samples with parts that I like, for example one hat sample has a transient sound I like and another has the sustain/decay that I want and I'll stitch the samples together and fuck around with the crossfades in ableton until I'm happy with the sound. Freeze and flatten (bounce to audio) and use that new sample. I find that layering samples can sometimes just become a complete mess and this method will generally sound cleaner. That's not to say that I avoid layering, I just find this method works better the majority of the time.
