2.Exploring the 303’s modulating envelope

1

Just as we did before, load up the 303 in your DAW, and select an unused Pattern and Patch from the drop-down menus. Because the sequencer is empty, you will have to trigger your sound from your keyboard, to audition your sound, at least for the moment!

2

As we’re looking to keep with something classic, we’re going to stick with the marginally richer sound of a sawtooth. Do feel free to experiment with the Square, but for our purposes, the Saw will be more appropriate.

3

With this patch, we’re going to drive the filter a little harder; set the Cutoff to around the 1 o’clock mark, but this time set the Resonance to the absolute maximum. This should result in a whistlelike sound.

4

The 303 comes with a very basic single-stage envelope, offering control of decay, but engineered exclusively for modulating the cutoff as part of the filter. Adjust the Env Mod pot to 1’ o’clock. This will dictate the amount of modulation that’s being applied.

5

The Decay pot controls the length of decay phase being applied to the cutoff. As a starting point, place it at around the 11 o’clock position, which will still keep the decay phase relatively swift.

6

In order to exaggerate the filter resonance, we’ll apply some distortion to the signal. Open the effect section and select Distortion, via the Drive Type pot. Then increase the Depth by placing the pot at around the 2 o’clock position.

7

We’re going to use the 303’s onboard sequencer again, so open up the sequencer section, by clicking on the Edit button, located next to the main keyboard. The Sequencer should reveal itself below.

8

If you’re not so good at programming notes, or want some inspiration, using the Random sequencer option could be perfect for you! Merely press the Generate/Undo button, for an instant set of notes, glides and slides!

9

Once you have your randomised sequence in place, you can edit and tweak to suit your needs by muting or editing notes and accents. Try exploring the Randomize elements; each of the four elements can be accentuated or reduced, by dragging the appropriate line.
