Sonic Pi v2.1 Release Notes

  • Friday 21st November, 2014 (view commits)

    🚀 The focus of release is very much on technical improvements, efficiency 💅 and general polish.

    The most obvious and exciting change is the introduction of the live_loop which will change the way you work with Sonic Pi. For more information on live_loop take a look at the new section in the tutorial. Another very exciting development is that v2.1 marks the 🏁 official support for Windows thanks to the excellent work by Jeremy 🚀 Weatherford. Finally, this release is also the first release where Sonic Pi has a Core Team of developers. Please give a warm welcome to Xavier Riley, Jeremy Weatherford and Joseph Wilk.

    • 🆕 New fn dec - decrement
    • 🆕 New fn quantise - quantise a value to resolution
    • 🆕 New fn factor? - Factor test
    • 🆕 New fn at - Run a block at the given times
    • 🆕 New fn degree - for resolving a note in a scale by degree such as :i, :iv
    • 🆕 New fn chord_degree - Construct chords based on scale degrees
    • New TL fn use_sample_bpm - for changing the BPM based on a sample's duration
    • 🆕 New fn rest? - Determine if note or args is a rest

    • New fn set_control_delta! - Set control delta globally
    • 🔀 wait now handles both sleep and sync functionality
