Hello - I’ve been trying your code (thank you!) to learn, and despite reading around/experimenting am still confused by _tick_ - can someone explain the diff between  
tick (as here)  
puts tick (in the glossary)  
xxx.tick (in the tutorial)  
why does this example need n+1, if tick does +1 increments through an array as default?

The examples in the tutorials are a bit different, so I’m thinking again your example might be Ruby syntax I need to learn.  
It sounds like ‘tick’ is hugely versatile if I can crack it!  
Thank you anyone who can help.

Hi @rebelcello  
I recently experienced some “unexpected” tick behaviour, while writing various rhythmic functions - purely because I’m a Ruby Nuby 😃

I found Sam’s comment here [Creating values for a fade - #6 by samaaron](https://in-thread.sonic-pi.net/t/creating-values-for-a-fade/5003/6) very clear and succinct. I too have been doing some intermittent Ruby learning, to try to ‘think differently’ about Sonic Pi and live coding. Let’s see how we get on 😉

Great, thanks @brendanmac - I’m on the Ruby sidelines thinking prob need to dive in 😃

Sam’s comment is helpful, thanks. Having finally got head round i++/n+1 and arrays, I’m trying to relate this to what the tick functions do - a super-efficient way of handling incrementing?

Fear not, have had fun playing with other people’s code but the obstinate part wants to really grasp it 😅 We’ll get there. Will post anything if I get a ‘by jove, she’s got it’ moment

I have put youtube video related to this drum fills:

Small tip, you can make the lists easier to read by using  
`bd = "x---x---x---x---"`  
and  
`if bd.look == 'x'`
