Hi @jrm
Some interesting ideas in your code. Thanks to share you ideas with the sonic pi community !

[Eli]

Okay… I thought I was getting quite good at SP, but your
code has me flummoxed…

You use: set once in your code, in :main

  **set :note, [n,r,0, c_type]**

but you never use get: anywhere to bring
back the values…

You use sync in just about every loop:

 **n,r,transp, chord_type = sync :note**

but there’s no cue: in the whole of your code.

F1 help on sync: says the following:

Pause/block the current thread until a cue heartbeat with a matching cue_id is received. When a matching cue message is received, unblock the current thread, and continue execution with the virtual time set to match the thread that sent the cue heartbeat. The current thread is therefore synced to the cue thread. …

Yeah… I really need explanation of your control process, please.

Eli…

This is a slightly sneaky one @Eli! it’s understandable that it might not be so obvious though, unless you’ve read specific pages in the lang reference.
You may recall that both set/get and cue/sync operate on the time state store. In fact, set and cue are equivalent, as are get and sync. (Well, not quite, see my further comment below )
So here, @jrm is mixing the two sets of commands - and in this case it works just fine.

[Eli]

Sneaky? SNEAKY?!…

It’s down right underhanded, is what it is Sir!

I call ‘FOUL PLAY’… this is just not Cricket, Sir!!.

Grumble, mutter

Eli…

[ethancrawford]

Actually, forget that

set/get and cue/sync are equivalent when it comes to storing and retrieving data in/from the time state. get doesn’t block. So in that regard, it can’t be used to pause/wait/sleep like sync.
@samaaron - you will know how it all works - feel free to elaborate or correct me if necessary

I’m pretty sure this is all covered in the tutorial. Please let me know if it’s missing anything: Sonic Pi - Tutorial

Hello @Eli
In section Passing values into the Future of https://sonic-pi.net/tutorial.html#section-10-2 there is an example where a value is get from store using sync. This is a shortcut for cue + get.
I just tried syncing on a loop but I got nothing.

Definitely cricket

In section Passing values into the Future of Sonic Pi - Tutorial there is an example where a value is get from store using sync. This is a shortcut for cue + get .

Just to be clear, sync is not a shortcut for cue + get. This thread might help shed some more light:

Help with understanding cues/syncs

Hi, new to Sonic Pi and very keen to use it. I’ve been through the tutorials and got very excited about using cues and syncs for controlling many arps and voices…but…clearly something I don’t understand about the model. Without a solid mechanism for doing this I can’t build what I need. If anyone could point me in the right direction I’d be very grateful. In the simplified code (at the end of this post) I have one live loop that cycles between two chords and plays the current one, and another…

In particular this section:

@samaaron

• get - this simply retrieves the latest value at the current time (or no value if none is found). This does not block the current thread in any way and is assumed to take 0 time.
• set - this puts a value at the current time into the Time State. It does not block the current thread and is assumed to take 0 time.
• sync this retrieves the next value from the current time and if no value is already there and waiting it will block the current thread. The amount of time this takes depends on when the next value is available. You can therefore treat sync like a special kind of sleep where you don’t specify the time explicitly - rather it’s just the time of the next matching event

Hi! Just checking in for the first time.

If someone has an account on Github, please post the code in there so that people can read it easily. I can’t do that right now. Though I’d like to help the community.

And add a sample audio file too, it is necessary after all. If possible, choose an open format that does not require codes which are not always available for install.

And optimize the page loads for the https://sonic-pi.net/tutorial.html#section-10 page. Just ask a web developer if you’re unsure.

---

And if you don’t want people to mispronounce your name, use some hints. I don’t care about my name, but some people on other “friendly” forums get really weird about that. And don’t respond kindly to reasonable advice.

Hi Enon the Great (hum hum…)

What the hell are you talling about ?

Hi @submitReportToPast,

Actually I think code snippets like this are much better placed here in the forums. Requiring people to use and understand external sites like GitHub raise the barrier to entry - especially for those that are brand new to programming in general.

Perhaps for much larger and unusual projects there might be some benefit, but in general I highly recommend that people use the forums for sharing and discussing their music code

And optimize the page loads for the https://sonic-pi.net/tutorial.html#section-10 page. Just ask a web developer if you’re unsure.

I wrote the code for the tutorial and manage the website. I’m not quite sure what you mean by “optimising the page loads”. Do you mean compress things? Use a CDN?

It’s only a simple site that doesn’t see huge traffic and I’ve not noticed any overly large page load times or data transfer amounts.
