Overview
10 E-MU Systems
The extremely flexible yet easy to use 4-layer synthesizer voices make it
easy to build sounds of any kind. Layers can be switched or crossfaded
using key position, velocity, real-time controllers or any modulation source.
Xtreme Lead also contains 50 different 12th order resonant & modeling
filters which are used to shape and modify over 1200 waveforms contained
in 32 megabytes (MB) of ROM.
64 modulation sources include three multistage envelopes and two LFOs
per layer, as well as full MIDI control over virtually every parameter. The
digital patch bay, with 24 cords per layer, (and 12 more cords per preset)
lets you connect modulation sources to 64 destinations in any imaginable
way. The patch bay contains a set of arithmetic modifiers, letting you create
complex synthesis models. Synth parameters as well as arpeggiator and
BEAT tempos can be controlled from XL-1's internal clock (or an external
MIDI clock). Up to 8 LFOs and 12 envelopes can be perfectly synchronized
at different rates. This is an extremely powerful synthesizer!
Four front panel real-time controllers give you control over 12 user-
selectable parameters. The real-time knobs can adjust multiple parameters
at once, allowing complex levels of control. For example, one knob can
simultaneously turn up filter cutoff, while detuning one sample, and
adjusting the release time of the volume envelope. Virtually every synth
parameter in the XL-1 is controllable using the real-time knobs or by any
internal or external control source.
Once you have created your preset, you can add richness to your sound
using XL-1's 24-bit stereo effects. You can choose a different effects setup
for each preset from over 60 algorithms. XL-1's effects section is actually
two separate effects processors with control over each wet/dry mix level on
four effects sends. Effects Processor "A" contains primarily ambiance
algorithms like reverb and delays, while effects processor "B" contains
primarily spectral algorithms such as chorus, flange, phase, distortion, and
delay. Effects can be linked to each preset or used globally to further
enhance your sound.
Other features include multiple solo, voice assignment and performance
modes for expressive control, 12 user-definable alternate tunings, and, of
course, an extensive MIDI implementation.
This is the Getting Started Manual for setting up and playing Xtreme Lead.
The first part of the manual describes how to unpack and setup the
hardware. The next chapters provide step-by-step instructions for the most
common and widely used features of Xtreme Lead. This section also defines
each of the parameters and provides information on how to use them.
The complete operation manual is provided to you in pdf format on
CD-ROM. The CD-ROM contains pdf files for both Mac and PC as well as
the complete MIDI SysEx specification and a software downloading tool
which allows you to retrieve the latest software and new features from the
world wide web.
