Step Sequencer Project - Pierre CHOUTEAU

Following the different steps for the stepSequencer project, I started by setting it up with the 'bascis' instructions (Master volume, effects lines, BufferSource creations, Beat follower track, dbToLinear...).

Then, I added some personal elements to go further into its functioning:

  • Additon of the ability to start and stop the system with buttons
  • Addition of a controllable reverb, which can be activated with buttons and sliders (the reverb comes in at the end of the chain, on the master)
  • Additon of the ability to modify the BPM from the user interface
  • Modification of the user interface to make it more accessible
