ESI Operation Manual
Sample Inputs
The two sample input jacks accept any low to high level input (micro-
phone to line level). Input impedance is 10K. The gain of the sample
input preamplifier is controlled from the setup screen in the Sample
Management module. When in the Sample Management module the
sample inputs can be monitored from the main outputs or the head-
phone jack.

MIDI Connection

ESI provides a MIDI IN, a MIDI OUT and a MIDI THRU port.
• The MIDI IN port connects to the MIDI OUT port of an external
MIDI controller which could be a keyboard, a sequencer, MIDI
drum kit or whatever. Note that the ESI can only respond to
information that your controller transmits. If your MIDI keyboard
does not have velocity and pressure sensitivity, the ESI will not
respond to velocity and pressure.
• MIDI OUT can be connected to another MIDI instrument or
computer. The MIDI OUT jack is used to transmit MIDI sample
dump information (transfers sample data).
• MIDI THRU simply re-transmits any information received at the
MIDI IN port. Use cords that have been designed specifically for
MIDI. While regular 5 pin DIN cords may work, they are not
shielded correctly for MIDI use and may cause ground loops
between equipment.
Footpedal and Footswitch Connection
Control pedals and footswitches can be connected if your MIDI
keyboard has inputs for them (most do). The MIDI keyboard translates
the controller movements into MIDI data which is received by ESI.
Controller data is sent over MIDI on a particular continuous controller
number assigned by your MIDI keyboard. ESI must be set to receive the
data using the same continuous controller number.
For more information, see MIDI Globals on page78.
110V / 220V Operation
The ESI may be used in either 110 volt or 220 volt environments at
either 50 Hz or 60 Hz. No change of voltage settings is required.
ESI automatically switches itself for 110 or 220 volt operation.
Digital I/O (Turbo option)
The optional Turbo card contains a digital interface which allows ESI to
transfer digital audio back and forth with other digital devices equipped
with S/PDIF digital I/O. Keeping the signal in the digital domain is
desirable to keep the signal to noise level as high as possible.
The digital input allows you to sample directly from a DAT recorder or
other digital device. The digital output reflects the data at the stereo
outputs of the ESI. See the Sample Management module and Main
Output Format (located under Special in the Master/Global menu) for
more information.
