Overview The ESI-32 has an enhancement of the OS developed for the Emulator III in 1988. The
Operating System is held on two 256 KB EPROM chips, making a total OS size of 512 KB. The OS can only be upgraded by replacing the chips.
OS 1.4 The first OS launched with the ESI-32. Two major bug
fixes. bus error and sample feedback on power up.
OS 2.0 A bug fix release which improved the data encoder acceleration, provioded faster boot times from a Syquest drive,
cleaned up the CDROM loading and implemented some screen changes in the Digital Processing Loop feature.
OS 2.1 This was a major improvement over previous releases, there are new features as well as a number of bug fixes.
- Preset and Samples can be loaded from Floppy Disk
- The Scrub Wheel is implemented
- MIDI receve Program Change has on/off
- SMDI (SCSI sample dump) support
- PC and Mac support
- EIIIx compatibility
- Drive Select shows all devices
- Load/Save shows bank size
- Controller 32 causes Pitch Bank
- Faster SCSI and more compatibility
- Audition from Disk volume increased
- Improved signal quality in Doopler/Pan and Digital Tuning
- Improved Data Encoder resolution
- Akai and EMaxs II import process improved
- ESI-32 SCSI ID renamed ESI-32 (Local) ID
- Mac on SCSI bus renamed Avoid Host on ID and can be set to any value from 0 to 7
OS 2.12 This version supports the newer Motorola Processors.
OS 3.00
The initial version 3 release.
OS 3.01 This software original came with the TURBO kit, but it introduced a MIDI sample dump bug, which had to be fixed in a new release - version 3.02.
OS 3.02
The latest software with all version 3 features and the MIDI sample dump problem fixed. sample bug fixed.
OS 3.0x Features This major version of software has many new features for the ESI sampler and bug fixes. Still available from E-mu Systems at $99. The new filters types are direct copies of
those implemented in the Orbit sound module.
These digital filters originate from the Z-plane filter technology first used in the Morpheus module, and are; two High Pass, three
Band Pass, three new Low Pass filters, a Flanger, three Swept filters, three Phasers, two Vocal filters, and the famous Bottom Feeder (bass distortion).
This OS is still available from E-mu Systems, priced at $99. It comes in a large cardboard box, with a manual addendum, installation guide, two EPROM's and a chip removal tool.
- 17 filter types
- Assignment Groups
- Sonic Enhancer
- Export Functions
- Velocity Ranges
- Output Boost
- Support for Turbo Card
- Support for NEC CDROM's
- SCSI drives to 4 GB
- Improved operation with JAZ drives
- Improved compatibility with non 512 byte sector drives
- Improved pitch shifting at extreme transpositions
- Pitch Bend up to +/- 12 semitones
- Dynamic Allocation replaced with Assignment Group
- New realtime filter control routing- VCF not on to Q
- Filter Q can be controlled by the position of a real tim controller at not-on time
- Finer Ratio Resolution (1/10 of a percent) in the Digital Processing, Time COmpression alogorithm
- Improved stero phase lock in Digital Processing Time Compression alogithm
- Two additional alogorithms added to Time Compression and Pitch Change
- Improved trigger button response, up to two buttons at once
- H chip filter popping eliminated
- G chip bandwidth improved
- Trigger button ghosting remioved
- Thermal drift of volume knob eliminated
- ESI-32 typo on SCSI page sorted
The digital sonic enhancer is a function that has been added to
the Digital Processing menu. It adds brilliance and 'cut' to a sample, making it stand out in the mix.
