League lead

This patch is often recreated by stacking oscillators tuned to open fifths. Given that the original Jupiter-4 had a single osc (+sub) per voice, we’ll leave the fifths to you. We’ll be using BazilleCM. Shut off the Delay, disconnect Osc 1 from Out 1 and send Osc 1 to a Filter input instead.

Set the Filter’s Cutoff to 25. Run a cable from Env 2’s Out up to the Filter’s lower-left jack and max the knob above that jack. Go to Envelope 2. Set its Attack to 15 and the Decay to around 33. The Sustain should be set to around 41 or so, and Release should be set to 62.

Send Osc 2’s output to the other Filter input, and find Osc 2’s PD Value knob (above where it says Saw) and crank it full. Run a cable from the Filter’s 24dB Output up to one of the Out 1 jacks. Locate Osc 1’s Fine Tune knob (above Cents) and set that to -7.0. Set Osc 2’s Fine Tune to 7.0.

Next, go over to Env 1. Give its Attack slider a nudge. The Decay and Sustain settings are fine. Push the Release up to 40 for that characteristic tail-out. Fine tune as you like. Play the sound using open fifths and stick a fat bass patch under your left hand for the full effect.
