In this contest, you can only use one synth (this month it's Zebralette), so everything from lead to kick drum is one separate instance of zebralette. FX use beside eq and comp must be sparse. No chorus, or heavy disto unless part of synth onboard effects.
While its not mandatory, I created every sound from init, its part of the fun, in my opinion.
~20 instances of U-He Zebralette.
