I’m a little stressed all the time right now, so I thought I’d channel that into this track. It’s a little longer than required, so the next participant can feel free to chop it up and rearrange it as needed!
I recorded some organ glissandos using my Nord electro. I knew I wanted some tremolo to fade in and fade out, so I experimented with using Ableton’s Max4Live Shaper and Envelope Follower tools, which were fun to explore.
The Envelope Follower controls Amount of the tremolo (the tremolo is actually Ableton’s Auto-pan plugin with the Phase set to 0, so there’s no stereo effect), so that the tremolo kicks in 500 ms after an audio signal is detected. I wanted it to be a bit longer, and now in retrospect I see that would have been possible by setting it to follow rhythm instead of time.
Then, there’s a Shaper Max4Live plug-in set to constantly decrease the Rate of the Auto-pan over 2 measures. It is mostly synchronized with the organ part. Sometimes the organ part breaks free of stuff happening every 2 measures, so it’s a little out of synch with the Shaper, but I think that’s ok - it adds a little variety.
Then I ran the organ sound through Izotope’s Vinyl plug-in and also Klevgrand’s DAW LP to get s ome distortion and vintage sound. I especially like the middle part - I might resample that myself and use it in a beat.
The final step was Klevgrand’s Grand Finale plug-in, which boosted my CPU usage to like 112% 
Well worth it!
