It depends on how steep a cutoff you're using, as well as your Q. An aggressive cutoff (I'd probably consider 24 dB pretty aggressive), will create a huge phase shift at your cutoff point and can actually create quite the boost in volume. If you're insistent on using an aggressive cutoff, either set a fairly low Q or use a linear phase EQ if possible.

Man, those are some awesome tracks. Why'd you stop, just getting bored of the style?

Oh man, this sounds fucking awesome. It's your track so ultimately your choice as to how you want it to sound, but I'd maybe wait with the lead for 8-16 bars in the "drop", maybe tease it a bit and then bring it in. Your chords sound really good and I feel like they could maybe be given the spotlight for a bit.

I really like this, all the acid sounds playing off of each other sound awesome. Might just be me, but I feel like that acid sound sitting dead centre that comes in at the 12 second mark was over EQ'd, it would probably sound better with more low mids on it.

I feel like motivation will always come in waves, I've had times where I can go a few months without feeling any motivation to write music. I think the key at that point is still trying to further yourself on the technical side of things. Also forcing yourself to sit down and just write something can usually spur some creativity/motivation.

I've got a ton of years of classical music training, piano, played clarinet in a big stage band, guitar, bass, and I've dabbled in other instruments. Taught myself how to use ableton once I was sick of working with bandmates, I prefer having the ability to be in control of everything I'm doing.

I think I was able to recreate the lead from the first track in Spire. Osc 1 & 2 are at full volume, osc 1 is tuned up 12 cents, detune set to 690, density at 500, 7 voices. Osc 2 is tuned down 12 cents, detune at 690, density at 425. Both oscillators are at full width. Routed to an infecto filter with a bit of resonance. All that then runs through some soft distortion set at about 25% dry/wet, set the drive to taste. Set your delay and reverb and you should be good to go. The key with these types of saws is the detune between the oscillators, not just the detuning on the individual oscillators. I've found that by spreading your 2 oscillators by +-12 cents in this case it gives you a less harsh sound.

Take a track from whatever genre you're producing, drop it into ableton and break your arrangement into sections of 8-16 bars. You'll have a general template for said genre at which point you can take your idea and fit it into the template. This was probably the one thing that really helped me go from 16 bar loops to finishing tracks within the past year. And just go with your ideas, write them out and don't worry about sounds initially. Just get something down and then you can mess with the sound until your ears fall off.
