ORIGIN (thicc bass) by @campkili
This is a simple patch that puts out rich harmonics. It's a great starting point for further experimentation.
ORIGIN is also available as a free file download containing individual note samples (C-1 to C7, 2 layers of velocity) and an MPC Keygroup at https://www.campkili.com/mpckeygroups
Tip: Use a frequency visualizer (Ableton EQ 8 for example) to observe the activity of frequencies as you turn knobs and shape the patch sound. Planning how you want your frequencies to behave is very helpful when you go to mix. If your desired frequencies are targeted, it's like you've done a bit of mixing before even recording something.
