303BOX / LEARN BY DOING

What would you like to make work today?

Choose one exercise, listen to the result and keep a decision of your own. The first three paths need no hardware or MIDI permission.

Build a pattern

Enter sixteen steps and compare the effect of one rest on step six.

Outcome: Two versions of a phrase and a reason for your preference.

Using these exercises

Example links ask before replacing bass steps and title. You can undo the last example load; tempo, rhythm and sound settings are preserved. A/B recordings are educational software synthesis. Your patch may sound different; the clips are not presented as hardware recordings.

Each path has a distinct job: the pattern workshop covers note entry, the arrangement workshop covers layers, the connection guide covers live MIDI, and the lab covers memory operations. Start at the step you need rather than reading every article in order.
