The Emax is a 12 bit sampler and changed alot over
the course of it's production run. Because of this there are 5 different
Operating Systems. It is still very desirable because it contains
true SSM analog filters creating a warmth and punch most modern
samplers don't have.
Operating Systems
-
Emax 3.2 - for base model
-
Emax HD 1.1 - for models with
internal hard drives
-
Emax SE 1.1 - adds SE functionality
to non-HD models
-
Emax HD SE 1.1 - adds SE functionality
on HD models.
-
Emax Plus 1.0 - adds the ability
to select a SCSI ID for an external HD.
The Basics
- 5 Octave velocity sensitive keyboard C to C or
3 space rack
- 512k of proprietary memory (not expandable)
- 3.5 inch floppy disk drive (uses double sided,
double density (DSDD) 720k floppy disks)
- 14 Velocity curves
- Velocity can control VCA level, VCA attack, VCF
cutoff, VCF attack, and VCF Q.
- 32 Character Backlit LCD
- RS-422 connection
- MIDI In connection
- MIDI Out/Thru connection
- Programmable Arpeggiator
- 16 track "scratchpad" sequencer
- Clock In (Clock In can accept 24, 48, or 96 ppq,
the pulses should be at least 1ms wide and 1 to 5 volts.
- Clock Out (Clock Out sends a 24 ppq which is 5
volts and about 6ms wide)
- 2 Programmable wheels for real-time control over
pitch, filter cutoff, AHDSR attack rate, level, LFO modulation index,
etc.
- 2 Footswitches
- 1 Footpedal
-
- HD models came with a internal Miniscribe model
8425S 20Mb Hard Drive
Audio Out and In
- Right / Mono Output
- Left / Stereo (headphone) Output
- 8 Individual mono outputs (individually assignable)
- Sample In (mono)

Voice Architecture
Each of the 8 voices has it's own set of the following
analog processors:
- Lowpass voltage-controlled filter (VCF) with AHDSR
envelope generators
- Voltage-controlled amplifier (VCA) with AHDSR envelope
generators
- 8 LFO's with adjustable rate, delay, and speed
variation
The Emax CAN chorus its voices without loss
of polyphony.
- Truncation
- Looping (Crossfade and Equal Power)
- Digital combine
- Sample reversal, as well as rate and pitch conversion
- Splicing
- Advanced Split and Layer
- Velocity controlled crossfading between samples
- Individual tuning and attenuation for each sample
Synthesis (requires SE or SE HD OS)
Transform Multiplication
Transform Multiplication is a digital effect which
merges together 2 sounds in such a way that frequencies common to
both sounds are accentuated while uncommon frequencies are discarded.
It works best on harmonically rich sounds.
Spectrum Synthesis
Spectrum Synthesis (SE) allows you to specify up to
24 complex waveforms, (called Spectrums) and to either step or fade
through them during the course of a sound. The 24 waveform locations
are called Time Slices, since they represent the waveform at that
slice of the sound. This method allows more complex and interesting
sounds to be created. In addition, each partial (sine wave) can have
a 24 point envelope that determines the pitch of that partial over
the course of the sound.
Each Emax SE voice can consist of two synthesized
timbres, a synthesized timbre and a sampled sound, or two sampled
sounds. The resulting voice can then be processed using the Dynamic
Processing features and placed anywhere in the stereo field.
