Ensoniq SQ-80 Cross-Wave Synthesizer:
I have an SQ-80 for sale.  The SQ-80 is a powerful performance
oriented synth with a limited on-board sequencer.  I bought it because
it has a very large timbral repertoire;  it seems to do meaty analog
synth sounds as well as sounds that are considerably more "digital".
Below are a list of features extracted from the owner's manual:
  o Eight-voice polyphonic poly-timbral synthesizer, capable of
    playing eight different sounds at once, with dynamic stereo
    panning for each voice
  o Voice section employing Cross-Wave synthesis;  combine different
    attack and sustain wave segments to create complex, dynamic sounds
  o 75 sampled waves (includes a drumset) serve as the sound source
  o Dynamic voice allocation:  each sequencer track/MIDI channel has
    access to all eight voices
  o A full-featured MIDI controller keyboard capable of sending eight
    MIDI program and volume changes at once.  Keyboard is velocity
    sensitive, and transmits/receives velocity and polyphonic aftertouch.
  o Powerful matrix modulation scheme allows a very wide range of 
    modulation sources and routings.
  o A 3.5" floppy disk drive which writes/reads ordinary DS/DD disks
    allows fast and reliable storage of up to 600 sequences and up to
    1728 sound patches on a single floppy disk.  Also has a RAM-cart slot
    for patches that is compatible with ESQ-1 RAM-carts.
  o Does sysex dumps to its floppy disk for any sysex capable MIDI device
  o 80 character fluorescent display and user-friendly "page-driven"
    programming scheme provides a fairly humane user interface
  o Stereo line-outs, and stereo headphone jack for private listening
  o Sound programs and sequences are upwardly compatible with the ESQ-1
    so that sounds and sequences created for the ESQ-1 can be played on
    the SQ-80.

This SQ-80 has been the main MIDI controller in my studio for quite a while
now.  It has performed ably in that role, and has also been a heavily
used sound source at the same time.  The SQ-80 seems to have been designed
with this role in mind, and it works very well with my software sequencer
(WinCake) in its multitimbral mode.

short samples (there are 75 of them) as sources, then these waves
are processed with a sophisticated DCF-DCA arrangement.  The SQ-80
is capable of great things because of its 4-pole analog lowpass filter.
Simply put, it makes fabulous analog synth sounds.  But unlike most
good analog synths, it has a very thorough MIDI implementation so that it
works very well with a MIDI sequencer.  What I really like most about this
thing is that it is capable of making a very wide range of sounds.
This SQ-80 is about 5 years old (mfg. date 1/21/88).  It does have
an 8-track sequencer, but like most on-board sequencers, it is a pain
to use so I have avoided it.

REASON FOR SALE:
I am selling my SQ-80 because I recently joined forces with another individual
here in Boston, and we have more keyboards than space to put them.  I
recommend it for someone who is getting started in sequencing and needs a
powerful but economical master keyboard.

PRICING AND TERMS:
I paid $1300.00 for this synth a few years ago.  I am willing to accept
$650.00 (average r.m.m.s asking price is $733.00).  I will include a bunch of 
patches on SQ-80 floppy disks for the buyer of this synth, as well as the 
original Ensoniq SQ-80 owner's manual.

Price:    Asking $650.00 (everything)
Shipping: split shipping (UPS Surface COD) anywhere in the lower 48 states
