Chords, bass, lead and arp. The meat of any electro house track. I've included a MIDI file to show you how to get a "full" chord sound (not sounding whimpy). Make sure to spread your chords out!!! I like to start with the tone I want to be most dominant in the chord (usually the 3rd) and place on the highest octave without sounding shit. Then add in the 7th below the 3rd, then add two root notes below the 7th (1 octave apart, obviously

Hope this helps someone. Feel free to use these in any of your works (commercial/non-commercial). Or you could reverse engineer them to come up with your own (even better synths!)

Happy producing!
