I have added to the Lua examples in Csound 6 git a new script, "csound_ffi.lua".
This script demonstrates the use of LuaJIT to generate a Csound score and render it using an embedded orchestra in Csound 6 via the Csound API. There is no extraneous code, the
Csound API is called directly from Lua code, that is what FFI (foreign function interface) is all about. In addition the code demonstrates the use of control channels to control Csound instruments during performance from Lua.
The code is profusely commented to explain every step. Note that LuaJIT is a standard part of the Csound package for Windows. The intended use of this approach is in Android devices. LuaJIT is available
for most Android devices. I don't (yet) have Csound on any Android device, but the idea is either to use the Android Csound app with LuaJIT, or produce a new app that combines
Csound 6 and LuaJIT, so that e.g. a tablet or phablet could be a feasible tool for algorithmic composition and full-bore synthesis. The script is attached... Michael Gogins Irreducible Productions http://www.michael-gogins.com Michael dot Gogins at gmail dot com |

Hi Mike, just tried your example on my system (Ubuntu 12.04, Csound6 built from git) and it works fine. I only had to change 'dac7' to 'dac' in line 53. Thanks.

Thanks very much. As soon as I have a build of csound6 I'll give this a go. I've wanted to look at Lua for a while now. The only thing that puts me off is that Lua doesn't look like a strongly OO language. How does it compare to python in your experience (Other than the speed which I understand is much faster)?

It can be as oo as python, and almost as functional as scheme, but for oo you have to code setting the class function table in the class constructor. With luajit the ffi is another huge plus... On May 12, 2013 6:17 AM, "peiman khosravi" <peimankhosravi@gmail.com> wrote:

Thanks for the info. Sounds like I should have a go with it. Best, P www.peimankhosravi.co.uk || Subscribe to RSS Feed To receive emails about upcoming concerts visit this page & enter your email address in the 'follow' section. On 13 May 2013 03:37, Michael Gogins <michael.gogins@gmail.com> wrote:
