Re: PyRTCmix on github

Thanks Brad!

Do you have an example (in C) on a typical use case? Was Marcus' problem related to makegen or PField? If it's easy to get to work in C, it should work in python.

This looks really fine!  One thing (and I don't know Python at all) -- I wonder if there is a way to get Python to deal with PField-handle variables.  Marcus Bittencourt ran into this problem with a large C project he's been using... the old makegen() system is kind of creaky and may not work properly in all circumstances.

Hi everyone. I took some time today to make sure that PyRTCmix could get all packaged up and in one place. Check it out here: https://github.com/booherbg/PyRTcmix Download the tarball, clone it with git, or fork it in github. It's up to you :) It'd be nice to get feedback.

A few options:

Want to start fresh? Just run install_everything.sh and make sure you have the following packages installed: python-dev python-setuptools and cython. This script (peek at it if you want to do it yourself) will download the rtcmix daily snapshot, patch it up so PyRTcmix can use it, configure & compile, and compile & install my extension, permissions willing.

You don't *need* to have cython and/or setuptools (both are python tools), but you have to be comfortable editing a makefile. You only really need cython if you want to re-generate the .cpp file from the .pyx file but it's an easy install with apt-get.

See the INSTALL and README for more information. I haven't tested this on anything other than my ubuntu laptop, so YMMV. Also I have a strange buffer issue where sometimes the sound is garbled. I am curious if anyone else has this problem or if there are any suggestions as to what may be causing it. I'm also curious if other system's don't require patching. that'd be neat to know.

------------------------------------

There are four example files that seem to work*: arpeggiate.py, flutescale.py, sgranr.py, and wanderfreq.py located in the examples/ folder. This gives you an idea of how PyRTCmix is meant to be used (here is flutescale):

import PyRTcmix as p

from time import sleep

rrr = p.pyRTcmix()

rrr.printOn()

sleep(3)

print ("loading metaflute...")

rrr.cmd("load", "METAFLUTE")

sleep(3) #just to be safe

rrr.cmd("makegen", 1, 24, 1000, 0.0, 1.0, 1.0, 1.0)

rrr.cmd("makegen", 2, 24, 1000, 0.0, 0.0, 0.05, 1.0, 0.95, 1.0, 1.0, 1.0)

rrr.cmd("SFLUTE", 0.0, 1.0, 0.1, 106.0, 25.0, 5000.0, 0.5)

rrr.cmd("SFLUTE", 1.0, 1.0, 0.1, 95.0, 21.0, 5000.0, 0.5)

rrr.cmd("SFLUTE", 2.0, 1.0, 0.1, 89.0, 19.0, 5000.0, 0.5)

rrr.cmd("SFLUTE", 3.0, 1.0, 0.1, 75.0, 19.0, 5000.0, 0.5)

rrr.cmd("SFLUTE", 4.0, 1.0, 0.1, 70.0, 15.0, 5000.0, 0.5)

rrr.cmd("SFLUTE", 5.0, 1.0, 0.1, 67.0, 16.0, 5000.0, 0.5)

rrr.cmd("SFLUTE", 6.0, 1.0, 0.1, 56.0, 17.0, 5000.0, 0.5)

rrr.cmd("SFLUTE", 7.0, 1.0, 0.1, 53.0, 25.0, 5000.0, 0.5)

while(True):

    sleep(0.1)

* weird bug when trying to 'import' any module after rtcmix. so far the examples only work if you use 'from package import module' or 'import package as p' syntax which is very very bizarre.
