Im running renoise 1.9 reg on an ibook G4 (OSX 10.4.11, 1.42Ghz, 1Gig SDRAM)
i have built a large RNS files for live performance (currently 600 meg and growing) .
I am working on a single hour long RNS file rather than building several small RNS files for each song individual song of the set, so when i perform live i can save on loading time between songs and just run through a single RNS (great, thanks to the speed change command!)
i seem to be having problems and wondered if anyone else has experienced this (?) . . .
The song often “glitches” or drops audio for a few milliseconds .
I first thought this is due to the latency . but as the processor is running at approx 20% for the duration of the song (never exceeding 30%), and i have tried various latency settings including the maximum 93 milliseconds but latency settings make no difference .
it seems to happen when a new sample enters the song, or when a couple of large samples start to play for the first time together . if i leave a single pattern running it gradually sorts itself out and stops stuttering/dropping out)
is it due to the speed at which my computer is trying to load these sounds from my HD or load into RAM ?
ive no idea about how renoise technically goes about playing or reading these large files, but as the first performance of my live set is due in a couple of weeks im very keen to find a solution to this problem as soon as possible .
Has anyone else encountered this when using a large RNS file or when using large samples within a song ?
i am running about 8 tracks within the file, though only about 4 are active at any one time . each track is monophonic (single column) and sample based .
im using an edirol UA-3 USB soundcard (i know its cheap) and am also connected to a Midisport 2X2 usb midi interface.
the RNS file and the samples i have used (which are now within the RNS file) are all located on my ibooks internal drive and are not from an external hard drive .
I cant seem to work out how to avoid this problem .
sorry for the long explanation . .
im also only using the built in renoise plugins, no third party or anything else. . it glitches and drops out during parts of the song where only small drum samples are being used as well as during the sections where the longer samples are utilised . . and each time i run through the song it seems to dropout/glitch at different points .
could it be that my ibook needs a good spring clean ?
any help or advice on how people dealt with similar problems would be very much appreciated . thanks
