I tested the code below (which is presented in the documentation), but it does not run on the editor:

live\_loop :rhythm do

sample knit(:bd\_haus, 3, :sn\_dolf, 1).tick

sleep 0.25

end

There’s an error message:

unknown sample :

I tried to edit the code but the same error kept appearing:

use\_bpm 123

live\_loop :rhythm do

sample knit(:ambi\_piano, 3, :elec\_beep, 1).tick

sleep 0.25

end

knit(:ambi\_piano, 3, :elec\_beep, 1) in fact is equivalent to de following ring (ring :bd\_haus, :bd\_haus, :bd\_haus, :sn\_dolf).

Verify that the samples **:bd\_haus** and **:sn\_dolf** exists on your system (you can see the full list by typing **sample** followed by a space). If they don’t exist, you can replace it with any of the ones that appear in your installation.

Actually I used Sonic Tau (online, on Chrome). All samples work when I use structures like

sample (ring :bd\_haus, :ambi\_piano).tick

Even if ring( ring :sample1, :sample1, :sample2, :sample2).tick is equivalent, it is not very handy and should be working anyway. As I told above, it is a bug on Sonic Tau cuz the system recognize the samples but does not the folowwing structure:

sample (knit :samplename, number)
