light, equipped with a high quality 16Mb sound library and a 76-keys
light-weighted action keyboard, the QS7 features unexpected facilities
as MIDI Master Controller.
In addition to this, digital outputs (Adat format), host computer
port, sample/song management (using the bundled Alesis Sound Bridge
software) and further details offer to this product a very large
flexibility for any possible musical application.
is good about QS7 is the large sound palette, the MIDI/digital/host
interface implementation, the great flexibility, the convenient
carriage and the really affordable price.
More in details, these general concepts are based on the following
Large polyphony and multitimbral capability.
The QS7 is able to produce 64 notes simultaneously using up
to 16 different sounds on 16 independent MIDI channels.
Accurate sound palette and huge program memory.
Based on the internal 16Mb Sample ROM library, sounds are organized
in 640 Programs (512 preset + 128 user) and 500 Mix (400 preset
+ 100 user).
The sample library is, in the most part, highly accurate and include
a large variety of sounds. Several multi-layer samples are also
provided for advanced dynamic control, simplifying programming and
optimizing polyphony at the same time. Also rhythmic loop are included
in order to expand creativity.
The feeling is that QS7 was designed to be fast in fixing any creative
idea. Based on a large number of keys, the interface allows to fastly
recall functions in a very intuitive way despite the little display.
What is really pleasant on QS7 is to work in Mix mode combining
program presets (mainly well designed) in order to approach fastly
to the desired musical result.
Of course sounds can be programmed from scratch.
A limitation in this sense can be the fact that filters are not
equipped with resonance, but for the typical resonance effect the
QS7 offers a lot of filtered analog waveforms, also available as
multi-layer samples in order to simulate cut-off dynamic controls.
Bundled Support Software CD.
Despite his unexpensive cost, the QS7 can offer very advanced features
(in terms of sound programming, sample processing and song arrangement),
thanks to the fact that these special functions can be managed through
external softwares based on MacOS or Windows 95 platforms.
A special CD (included in the package) combines Alesis an third
party softwares that are able to manage any possible programming
need. For example:
- song programming is supported by Steinberg Cubasis (Mac/Win licensed);
- sound programming is supported by M.O.T.U. Unisyn (Mac/Win licensed);
- sample processing is supported by Sound Effect (Mac shareware);
- flash RAM programming (including samples, sounds and songs) is
supported by Alesis SoundBridge (Mac/Win licensed).
Host Computer Port (serial interface).
What about QS7 connection with a computer? The Host port allows
the user to connect the QS7 directly to a Macintosh or a PC (with
an adaptor) serial port without the need to use any external MIDI
Thanks to the fact that standard Apple serial cables can be used,
the connection with any Macintosh computer it's really simple.
In other words, using a PowerBook and a QS7 togheter means to work
with a portable professional studio for any musical needs (live
applications, composing, sound/song programming and sample processing).
SampleCell, AIFF and SDII sample format compatibility.
Thanks to the SoundBridge software, WAV, AIFF and SDII (Digidesign
Sound Designer 2) format can be used in order to download samples
inside the QS7 optional Flash RAM cards (up to 8Mb of samples can
be loaded inside a Flash RAM card).
Another important feature of SoundBridge is the full compatibility
with Digidesign SampleCell.
Using a Mac with a SampleCell card is possible to create multisampling
Instruments that can be easily managed by SoundBridge for a data
transfer to the QS7 Flash RAM card.
Also SampleCell CD-ROM (from SpectraSonic, Ilio, EastWest, etc.)
can be used in order to create instantly a QS7 additional sample
library (and in this case there is no need of a SampleCell Card).
Using optional Flash RAM cards up to 16Mb of samples can be added
to the QS7 internal library and this means that a total of 32Mb
of samples can be managed in real time.
Data Card Management (Sounds and Songs).
Using optional Flash RAM or ROM cards, the QS7 can include on board
additional Program/Mix memories, Samples, Multisampling Instruments
(Digidesign SampleCell compatible) and Song sequences (0/1 format
SMF files that can be played via the internal SMF Player) for any
Advanced Sound Processing.
An Alesis Q2 effect unit is buit-in inside the QS7. This powerful
fx processor allows to use up to 4 independent sends with routing
and up to 8 simultaneous effects, depending fron the selected configuration.
GM (General MIDI) Compatibility.
In order to expand the range of possible musical usage, the QS7
is also GM compatible.
Depending from the user needs, GM can be useful for several purposes,
mainly the possibility to evaluate SMF files without the need to
own any specific instrument.
ADAT Optical Digital Outputs.
QS7 features also digital outputs in ADAT Optical format.
Up to 4 audio digital outputs lines (related to the 4 analog outputs)
can be used simultaneously for digital recording using Adat format
In this way the QS7 can be digitally connected to an ADAT MDM (i.e.
ADAT XT), directly or thru a digital mixer.
For more complex recording systems, a Wordclock In is also available,
virtually assuring full integration of QS7 with complex digital
Master Keyboard MIDI facilities.
Coming to MIDI, features seem to be very powerful.
In Mix mode up to 16 independent MIDI channels directed to external
sound generators can be controlled from the QS7's keyboard with
or without the parallel use of the internal sounds.
The control can be organized in layers with note limits in order
to create splits where required.
Additional MIDI real time controls can be assigned in any possible
way thru wheels, cursors and pedals.
Also the MIDI channel transpose is available.
In this way the octave pitch of several MIDI instruments can be
controlled directly by the QS7, allowing correct playability accordingly
with the programmed keyboard split, without the need to modify the
