PATTERN TOP-TIPS

Zebra CM is pretty effective at recreating something that sounds similar to an original 303. However, it’s arguably only 50% of the 303 equation, with the remainder being the sequencer-based pattern.

Due to its programming complexity, many classic 303 sequences were built around only 16-steps, with a mixture of both notes and rests. You can exhibit a form of random programming by opening up your DAW’s step editor, and literally clicking anywhere within a 1-bar pattern, ensuring you only have one note, or a rest, per step. Try making the first note of the sequence or loop your tonic note, the keynote of your track, and start by staying within the range of a single octave. You’ll be surprised at how good it sounds once you’ve placed some drums behind it.

The more adventurous can try extending the odd note over two notes/steps or more. As you’ll be entering notes in step with your mouse, all velocities should be the same. Try setting all note velocity values to 64, with the occasional note value of 100. Now you’re inducing a form of accent, as per the original 303.

Programming glide at step level is much more complex, but you can add Global Glide (far left of the Zebra interface), for a pretty fair sound-alike on a budget! Creating a gradual Attack and a longer Release in the amplitude settings of Env 1 makes a more enticing effect.
