Same issue: it is not working, the canvas remains blank....

I have typed....: a = feed_text "http://open.live.bbc.co.uk/weather/feeds/en/7114227/observations.rss"

a.each do |i| text rand(100), rand(100), i sleep 2 end

Sonic Pi responds....: undefined method `each' for #String:0xc7ae20

Connection initiated...

Do you have an example of command line plus URL that worked with you, be it for text or entries?

thanks in advance Chooc Ly

Hi Chooc,

your problem is that you're trying to iterate over a string rather than a list. feed_text returns a string representing all the text of the feed, and feed_entries returns a list of string for each entry.

If you replace feed_text with feed_entries in your code, it will work. However, be aware that that particular feed currently only has one entry :-)
