	Can you give the details of the soundfile Swallow.aiff ? number of channels in particular Also a generic remark -- can people please state platform and vcsound version when reporting difficulties? Not always the problem but it really does help in understanding the problems. ==John ff > using "oscil", "lfo" and "phasor" to read a file from "table" but it only > reads half the aiff file or table and then it goes back to the beginning > and > repeats.

	not knowing anything else about your file, if "ifilelength = 9644544" plays half the file and repeats, then "ifilelength = 19289088" will play the whole thing On 05/10/2012 06:34 PM, Cacophony7 wrote: > using "oscil", "lfo" and "phasor" to read a file from "table" but it only > reads half the aiff file or table and then it goes back to the beginning and > repeats.

	You might also want to use filelen to retrieve the length of the file in seconds rather than having to use Audacity to retrieve the number of samples./ On 11 May 2012 15:43, Justin Glenn Smith wrote: > not knowing anything else about your file, if "ifilelength = 9644544" plays > half the file and repeats, then "ifilelength = 19289088" will play the whole > thing > > On 05/10/2012 06:34 PM, Cacophony7 wrote: >> >> using "oscil", "lfo" and "phasor" to read a file from "table" but it only >> reads half the aiff file or table and then it goes back to the beginning >> and >> repeats.

	What is it you are trying to do? Your first example used diskin2 but then you changed to using a table opcode. What was wrong with diskin2 and why did you change? They both offer different things. The beauty of loading a file to a table is you can do anything you want with the samples contained in the table. With diskin2 you can read from different positions and change the pitch but after that you're stuck, more or less. You can break one big file into several smaller ones by only reading the relevant sections of the file. In practical terms it might be best however to just load the different samples. In terms of beat slicing I posted an instrument to this list a while back that would add breaks of sorts to a sound file and Jake posted some nice Csound/python examples recently that showed off some nifty ways of breaking up beats. You can probably find them in the archives. Rory.
