Always Check your tracks on multiple sources (computer speakers, car speakers, monitors) as you work. This is handy for identifying problem resonances and overloaded spectrums that might stress smaller speakers.
Transport a "good weight" kick and bass into a musical context. That is to say find a sweet spot and then transpose it onto a musical form.
3. 808 kicks with some 909 is a good combination. 808 is a better "all round" kick. 909 has the the thump but can overburden smaller systems.
4. Add some bussed guitar onto main guitar - use a frequency specific exciter or distortion and mix one saturated band back in. A kind of "filtered" element in the guitar.
5. Keep written notes on each track for different strategies etc.
6. Use the dynamic eq to duck the bass away from the kicks. Or you can use compression or ducking. Each has a different flavour.
7. Put onto YT or Bandcamp before full release in case tweaks are needed. Feedback from live sets or from media platforms is essential for making the final touches.
8. While mixing keep focusing on the stereo field and stereo image. Use the tremolo plug-in in Logic for panning and keep everything (some components) moving. Test also in mono to check for problems and mono compatibility.
9. Create separate logic projects for vocals and split the vocal into 2 or 3 tracks. Then work on these 3 tracks. Also record vocals with 2 mics - rinse and repeat. With the vocoded vocal on White Fur I split the vocoded tracks up into 3 parts and worked on them until they made a narrow spectrum whole.
10. A mix must be a dynamic version of a full spectrum track. Like a snapshot of a world. Everything must be transported into that world. Not exactly shrunk down - but something analogous.
11. When doing compression (particularly of bass sounds) don't forget to use the in-built filter to target bass frequencies. The filter allows the bass to pass through without triggering the compression (even though the bass is compressed once the higher frequencies kick the compression in). This filter is known as the "detection circuit" and most digital compressors have one.
12. Guitars can be squeezed down with Ozone or Neutron (sculptor) and then squeezed again until they only really push out at one particular frequency spectrum. "Over-controlling" the guitar is certainly a thing but you can really sculpt it down and still have it seem to be full spectrum. On Z-int the guitar is sculpted quite a bit and it still probably could be squeezed some more (but it does work as is....).
