For MachFive version 3.0 and later

• A minimum of 2 GB of RAM is required. However, since MachFive loads samples (or a portion of the samples) into the computer's RAM add as much RAM as possible to your computer; 4 GB is recommended. MachFive also allows samples to be streamed directly from disk thus freeing up RAM.
• Large hard drive(s), preferably at least 100 GB. The disk on which the sounds are stored must be a fast hard disk. See “Hard disk format”, below, for additional requirements.
• An iLok USB Smart Key from Pace Anti-Piracy. MachFive 3 is compatible with iLok 1 and 2. PLEASE NOTE: an iLok key is not included in the MachFive 3 package. If you are are upgrading from a previous version of MachFive, you can use your MachFive version 1 or 2 iLok for your new version 3 license, which is downloaded from ilok.com.
• A free USB port for the iLok USB key. Note that if you have multiple products which use iLoks for authorization you can consolidate multiple authorizations onto a single iLok; see this tech note.
• A CD/DVD disk drive for installation.
• A digital audio workstation program or other program that hosts AU, VST, or RTAS instrument plug-ins. Alternatively, MachFive can be used as a standalone application.

Mac systems

• Intel Core Duo CPU 1.83 GHz or faster; multiple processors or a multi-core processor is required. Intel Core 2 Duo CPU 2.0 GHz or faster recommended. Macs with PowerPC CPUs are not supported.
• Mac OS X version 10.8, 10.7, 10.6, or 10.5 (v10.5.8 or later is required).

Windows systems

• Intel Core Duo CPU 1.83 GHz or faster; multiple processors or a multi-core processor is required. Intel Core 2 Duo CPU 2.0 GHz or faster recommended.
• Windows 8, Windows 7 or Vista (32- or 64-bit; Vista SP2 or later is required).

64-bit operation

For native 64-bit operation, MachFive has the following additional requirements:

• Mac OS X version 10.8, 10.7, or 10.6, or a 64-bit version of Windows 8, Windows 7 or Vista
• 64-bit CPU
• 64-bit plug-in host application, if using the 64-bit plug-in

Hard disk format

Due to the large size of MachFive’s factory soundbank UFS files, the disk containing the soundbank files must be able to support individual files larger than 4 GB. This is determined by the disk’s file system format.

The default file system format for disk drives on Mac OS X and Windows are compatible with MachFive’s soundbank files:

• Mac OS X: HFS+ (Mac OS Extended, journaled or unjournaled)
• Windows: NTFS

The FAT32 format is not compatible with MachFive’s soundbank files, as it does not allow file sizes greater than 4 GB.
