In my testing of NOTION 4 running in 64-bit mode, I have encountered no problems running three instances of MachFive 3, and there generally is plenty of memory space available, since I have 20GB of memory on the 2.8-GHz 8-core Mac Pro (early 2008) here in the sound isolation studio, where I plan to do additional memory upgrades to get the total memory to 32GB. For other types of VSTi virtual instruments the general upper limit in NOTION 3 is 20 to 25 instances, where one "instance" maps to one "staff".
Īnd there is a significant difference in performance, where NOTION 4 running in 64-bit mode is not constrained in the way that NOTION 4 is constrained when running in 32-bit mode, which also is the case for NOTION 3, which only runs in 32-bit mode and is easily overwhelmed by what I call "heavy" VSTi virtual instruments, with MachFive 3 (MOTU) running in 32-bit mode being a "heavy" VSTi virtual instrument, where for example a NOTION 3 score on the Mac running in Mac OS X 10.8.2 can handle perhaps two instances of MachFIve 3 without becoming overwhelmed to the point that the audio skips, drops-out, and generally is degraded.
IK Multimedia is working on a 64-bit version of its SampleTank engine, and this probably will include updated sampled sound libraries, perhaps at a higher resolution, but to the best of my knowledge at the moment NOTION 4 continues to support standard CD quality audio, which is 44.1-Hz at 16-bits, so it mostly is a matter of getting the engine working in 64-bit mode rather than providing higher resolution sampled sound libraries. Ĭurrently, nearly every VSTi virtual instrument is available in 64-bit mode with the exception of the IK Multimedia VSTi virtual instruments, which at present are available only in 32-bit versions. When NOTION 4 is run in 64-bit mode, it is using native 64-bit instructions and variables, and it can use more memory, all of which maps to optimized performance, significant memory space, and generally improved everything, hence if your computer supports it, you want to run everything in 64-bit mode whenever possible. Regarding 32-bit verus 64-bit, the primary difference is that 32-bit applications are limited to using at most approximately 4GB of memory, and this limitation reduces the amount of work that can be done in a single NOTION 4 score with respect to VSTi virtual instruments and so forth.
Īnother possibility is that you never downloaded and installed the NOTION 4 bundled instruments, hence you are using the NOTION 3 bundled instruments, since it could be the case that some of the Classical Guitar stuff is included but not all the articulations, styles, and so forth, which is the way it works for pitch percussion, where some of the pitched percussion is included in the NOTION 4 bundled instruments but the full set requires getting the Expansion Sounds for pitch percussion and so forth. Some of the complete set of NOTION 4 native instruments are included with NOTION 4, and they are the "bundled" native instruments, but there are additional instruments which are sold as expansion sounds, and in this instance it appears that the Classical Guitar is one of the expansion sound instruments, hence you need to purchase the Classical Guitar expansion sounds. is there a significant difference in performance?
I'm just asking to be sure if it is not me who are doing something wrong.Īnd by the way, what is the difference between 64 bit and 32 bit. Is it just me or is the classical guitar not working in 64 bit mode?
