Subject[Csnd] lazy request for simple Python scripting example
Hello everyone,

actually this is a ~very~ lazy request, to be pointed to a blushingly 
simple and short example of scripting Csound (note events) in Python, 
that I can maybe even put on a presentation slide for a talk to some 
school teachers tomorrow, just to show what it would look like. I have 
as usual got too much to sort out in not enough time to be relaxed about 
it!

Hi Richard,
do you want to let Python write the score text file to be used by Csound, or generate events in realtime?

Here's my simples score write script that I used to use in a class earlier

SubjectRe: [Csnd] lazy request for simple Python scripting example
I was looking for something to show Python being used to send note event 
to a running Csound (I assume that's an available thing to do!). Or in 
other words, showing Csound as in a sense an extension module for Python.

But the first example you give, below, is useful as I can fit the for 
loop into a PP slide. Ideally, I would like to have an equivalent that 
sends the note event directly to Csound. I assumed Python could do that, 
buy maybe I am wrong there?

Persuading schools to install (a non-trivial exercise in their heavily 
locked down networks)  and use/teach Csound is one thing, and maybe 
quite a big thing, but as Python is already established for CS in 
schools, this might offer a relatively smooth "way in".

In the more general case and longer term, I am looking for real-time 
audio and MIDI modules for Python that would meet school's needs for 
simplicity, flexibility, etc...

SubjectRe: [Csnd] lazy request for simple Python scripting example
Ah, yes,
It is of course also possible to run Csound as a python module (import csnd)
I do have some examples of that buried somewhere, but not as simplified as those two.
Someone else probably has better educational examples for that approach.
Or, take the cb.py example in Csound/examples/python and use something like
cs.InputMessage('i %i 0 %i %i' %(p1, p3, p4))
to send score events to the loaded csound instance.

The reason why I don't use that approach as much is that it is rather cumbersome to create a sample accurate clock in python, so I started doing it the other way around, letting Csound be the master app responsible for time keeping, hosting Python for compositional logic.

you can find precise clocks in for example the pygame module (never actually used it),
or if you want to synchronize tightly with Csound, you can construct your own timekeeper and let it be incremented eack ksmps cycle (cumbersome)

Hi Richard,

You will need the latest version of CsoundQt which includes Python
scripting support. There is a builtin object called q which can be
used to interact with CsoundQt and running Csound instances.

Andy will hopefully have a Windows version for you to try soon.

Cheers,

the "keys.py" example looks good; but I don't have "ah.wav" to go with 
it. I could do with something like that but with very simple synth 
sounds - it's just to show the possibilities. John sent me something 
like that, using MIDI input, that works very well (a bit too hot for the 
Raspberry Pi though!); a similar one driven by Python would be great. 
However, the more I look at it, I have a lot to cover in less than an 
hour, so actually demoing Csound may be a step too far at this stage.

Another interesting way I bumped into today:

This is near the top of my list of projects to get back to. It's just that I took an exciting detour into the world of Arduino and microcontrollers, and plan on being here for a little while longer. As for Python, I'll just say I've been writing Csound scores since 1995 and Python makes everything far easier and is magnitudes faster to create scores with. The difference is quite insane and in no way am I exaggerating this.

Best,
Jake

I can report that what I was able to show teachers did appear to be 
received well, with some encouraging responses and comments (Scratch has 
all manner of timing issues, but can still be got to do some funky/cool 
things sound-wise), so the mission to get Sound and Music Computing into 
schools is hopefully up and running.

So the immediate requirement has now passed, and because of the almost 
inevitable late start and overruns, there was in the end no time to demo 
anything Csound-related, or any Python for that matter. I can now 
eliminate the "lazy", and I will look at putting some examples of my own 
together.

Nevertheless, I will always be interested to see/receive any reasonably 
compact examples of Python-driven Csound, that may for example 
demonstrate some teaching point, coding technique or topic. If people 
think of kids age 10 onwards, mostly just starting serious study of 
programming, perhaps being encouraged to create original sounds for 
games etc, that will give the general idea of level. So nothing too 
heavily mathematical or conceptually abstruse!

I suppose the ultimate goal is a (smaller!) counterpart to the Audio 
Programming Book, based on Python.

Have you also looked at Pyo? It is a sound engine that you can directly use
from Python....

It's on the list. there are two interconnected objectives - find the 
most suitable sound engine(s) for teachers and students to use, within 
Python (which schools already use), and advocacy for Csound.

SubjectRe: [Csnd] lazy request for simple Python scripting example
It's possible to have a Python-driven Csound system that hides most all of the details of Csound, and provides only a simplified interface for students to interact with. Here's a very simple example that provides students a single trumpet function with four parameters:

trumpet(start_time, duration, amplitude, note)

And then all they'd have to do is write a score with this single function:

trumpet(0.0, 0.5, -3, 'D5')
trumpet(0.5, 0.5, -3, 'G5')
trumpet(1.0, 0.5, -3, 'A5')
trumpet(1.5, 0.5, -3, 'B5')

etc...

All the actual Csound is hidden, and students could just focus on creating note events. And then as course continues, more and more functionality could be provided, slowly building the students computer music repertoire. This includes more instruments, computer programming paradigms such as conditional statements and loops, introducing concepts like random, sound design, etc.

Here's a list of examples I've put together that combines Csound and Python:

The top six audio examples here are from this Python library:

Jake
