Description
The ESQ-1 is actually two powerful devices -- an eight voice. poly-timbral Digital Synthesizer, and a flexible eight-track MIDI Sequencer -- built into one package. Whether you plan to use the ESQ 1 by itself, or as the master controller in your MIDI set-up, you‘ll find that it is a tool of enormous power and versatility for performing, recording and composing music.

The Synthesizer With three Digital Wave Oscillators per voice, thirty-two sampled and synthetic Waveforms to choose from, and 15 routable Modulation sources, the ESQ 1 is capable of producing a wide variety of rich, complex sounds. The five-octave, velocity sensitive keyboard can be split for different sounds on each half, layered for two sounds playing together, or even programmed for a Split‘Layer mode in which two totally different pairs of sounds play on each keyboard half.

Forty Programs, or 'patches', are stored in the Internal Memory, with another eighty available on an external, plug-in Cartridge, giving you 120 sounds to select from instantly. In addition, the eighty-character fluorescent Display shows the names of ten programs at a time, making it easy to quickly scroll through all the sounds, to find the one you want. These programs can be played as is, or they can be modified to suit yourtaste and then renamed and stored, either in the Internal or the Cartridge Memory. ' Editing of all programs, sequences, and ‘global' functions {such as Tuning, Bend Flange, etc.) is handled from the informative, ‘F'age-driven' Display which shows at a glance all the parameters associated with a selected function. Audio outputs are provided for true stereo, as well as a mono output. Programs can be penned continuously between the left and right channels.

The ESQ 1 also has an Amplitude Modulation (AM) mode which can produce bell and ring-modulator type effects. and a Sync mode for hard sync effects. The Sequencer The built—in Sequencer can record and play back 2400 notes (expandable to 10,000 with the optional Sequencer Expander Cartridge}. It will store 30 different Sequences, which can be combined into to Songs. Sequences and Songs can be saved to tape or via MIDI to diskette using an Ensoniq Mirage Digital Sampling Keyboard or Mirage Digital MuIti-Sarnpler. (You do have a Mirage, don't you?) It is a full eight track MIDI Sequencer, capable of playing eight separate polyphonic Tracks internally, each with its own sound; or sequencing eight separate MIDI devices at once: or both. Each Track has an adjustable Output level, a MIDI channel, a Program number, and a MIDI Status (LOCAL, MIDI or BOTH].
