Critic Reviews

Emu ESI4000

soundonsound.com

The E-mu ESI-4000 offers professional sound quality and versatile filtering, making it a capable budget sampler. However, its user interface could be more intuitive, and it lacks graphical sample editing and monitor output. While it keeps up with competitors like Yamaha's A3000, it doesn't stand out significantly in the crowded market. The sampler's expandable memory and digital I/O options are positives, but the effects section feels outdated. Overall, the ESI-4000 is a solid choice for those needing a reliable sampler, but it doesn't offer much innovation over its predecessor, the ESI32.

EMU samplers are the best

very analogue sounding sampler, samples in 16, 12 and 8 bit. Interface is second to none and is easy to do anything once you have your head around the semi modular operating system. As well as being a sampler it also has a great synth engine and the famed E-MU Z plane filters once the OS is upgraded to 3.02. Multiple outs and a joy to use as you can do lots of fabulous things with this, sounds great as the A/D conversion makes things really sit in the mix.

The E-MU sample library is also second to none and was used on soo many hit records in the 80's and 90's.

Always try to get one with a zip disk though as SCSI is slow and loading samples from 3.5 floppy's is no fun and is really impractical.

Great Filters

Great sounding filters but that's about it. Lack of third party libraries and non computer compatible file system makes this sampler unintuitive. Just like most vintage samplers, if you dont have a zip drive or cd-rom you are not going to do much with it.
