This is a small collection of modular synths racks (featuring a particularly large rack on the left) that I call The Vancouver Machine, because the cables leading all over the place is like Vancouver traffic; chaotic, yet somehow organized enough to make sense lol. This is built in SynthVR, a really cool eurorack sim built for virtual reality headsets.
The main function of The Vancouver Machine is to generate an entire song - verse, bridge, chorus ad infinitum. That's all contained in the leftmost rack. On the top are four pattern sequencers that control four more sequencers below. For the sake of clarity, the top four sequencers will be called the Pattern Sequencers and the bottom for sequencers will be called the Structure Sequencers. The Pattern Sequencers are designed to make the first Structure Sequencer loop four times. The first two buttons on the first Pattern Sequencer are enabled, which is connected to the Loop functionality to the first Structure Sequencer. When the Pattern Sequencer reaches a step where the button is disabled, the Loop functionality on the Structure Sequencer will turn off. The Structure Sequencer will then finish playing through its sequence a final time, then switch to the next Structure Sequencer.
The Second Pattern Sequencer now has the first two buttons off, the next two buttons on, and the next four buttons off. This allows the second Structure Sequencer to loop in the same way as described previously.
The Structure Sequencers hold all the pitch information for the notes being played by the oscillators on the lower rack. The oscillators are making a dead simple sound, but i've added a ring modulator that adjusts frequency accurate to the pitch of the note being played. That changes the timbre of the sound being made by the oscillator based on its pitch, which gives it a more naturalistic feel, without turning the pitch of the note into a jumbled mess as would be the case if the ring mod wasn't changing frequency based on the pitch of the oscillators.
The result is a complex machine that is very easy to knock out of sync, but when functioning as intended is capable of producing an entire pop song structure at the click of a button. I spent about two days chasing this White Whale, and I laughed like a maniac when I figured it out.
That's also the same day I started using Concerta for ADHD. I felt excruciatingly manic to the point that I could not control myself; all I could do was build The Vancouver Machine until it worked. When the Concerta wore off, i immediately broke down into a puddle of tears and became entirely inconsolable for literally no reason at all. ADHD MEDICATION IS COOL HUH :)
