LASS Full System Requirements
Library Size:
- 16.4 GB with loss-less compressed audio files (approximately 24 GB uncompressed)
Software Requirements:
Supported Interfaces:
- Stand-alone, VST®, Audio Units™, RTAS®, ASIO™, Core Audio™, DirectSound™, WASAPI™
Minimum System Requirements:
- Windows — Windows XP (latest Service Pack, 32 Bit), Windows Vista/Windows 7 (latest Service Pack, 32/64 Bit), Intel Pentium 4 2.4 GHz or Intel Core Duo or AMD Athlon 64, 2 GB RAM
- Mac — Mac OS X 10.5 or 10.6 (latest update), Intel Core Duo, 2 GB RAM
Recommended System Requirements:
Any decent 4 core (or greater) machine running a 64 bit capable operating system (newer Mac OSX, Windows 7 or Vista). There are many users who use LASS on one machine without issues (we’ve been accused of being overly cautious with the “recommended” system requirements — especially considering some of today’s faster computers — 4 and 8 core machines). And even for those who have lesser computers, you can use the full mixes or you can even use LASS to the fullest by rendering midi tracks. However, as a safety dead-line precaution, we only recommend 2 computers for those “prime-time” professionals who would use LASS to the fullest with deep divisi writing on all string sections simultaneously and playback everything in real-time with no glitches at lower latencies.
