INDSTRLZR
Multi Effect Unit

Ekssperimental Sounds Studio’s INDSTRLZR is a
multi eect device inspired by Chris Carters legendary
Gristleizer eect box which in turn was based on
an electronics DIY project designed by Roy Gwinn,
published as the ‘GEP’ (Guitar Eects Pedal) in
Practical Electronics magazine (July 1975 issue).
The INDSTRLZR features the same principle of an LFO
modulating a VCA and a VCF and comes with additional
features like programmable LFO shape, Multimode
lter, syncing, additional eects and CV and audio
modulation input.
Thank you for choosing INDSTRLZR!

INPUT IND. & TRIM
Input indicator, the brighntess is controlled by the input signal.
Trim input from -inf (-100%) to +12dB (+100%) Zero dB at 0%.
MODE
VCF: LFO -> Voltage Controlled Filter (VCF) cutoff
VCA: LFO-> Voltage Controlled Amplifier (VCA) level
BOTH: LFO -> VCF cutoff + VCA level
FILTER (VCF)
FREQUENCY: Cutoff Frequency 140 - 7500 Hz
RESONANCE: Boost signal around cutoff point
HP/BP/LP: High Pass, Band Pass, Low Pass selector
HP only pass frequencies above cutoff point, BP will filter out
frequencies above and below the cutoff point and LP will pass
frequencies below the cutoff point.
LFO (Low Frequency Oscillator)
RATE: Rate of oscillations 0,5 - 50Hz
DEPTH: Amount of modulation being sent to VCF or VCA depending
on MODE selction.
SYNC: Rate is synced to the beat
WAVEFORM: Select the shape of the LFO waveform, ramp up, ramp
down, triangular, square or PROG. (Custom waveform defined in the
Programmer unit)
CV INPUTS
Connect CV Signals to controll the corresponding parameters marked
next to each jack.
CV OUTPUT
An envelope follower signal can be tapped at this jack. The Envelope
follwer is placed after the VCF and VCA so that the modulated signal
will be output to CV here.
PROGRAMMER
OUTPUT: Trimming of the output signal from -inf (-100%) to +12dB
(+100%) Zero dB at 0%.
PAN: Panning of output signal from Left to Right.
FX1: 2x TRASHERS (Fuzz & Scream models) The trashers have
different tonality, 1 is muddier, 2 is brighter.
FX2: Echo and Reverb
LFO: Settings for the LFO, glide will smoothen the step transistions,
Random will vary the values by random. Reset will restart the LFO
when there is a gap of >1sec in the audio signal. (Global meaning it
will also affect the fixed waveofrms)
SHAPE: Define a custom LFO shape used when LFO is set to PROG.
by dragging the steps up or down.
PREF: Preferences; PAN MOD adds LFO modulation to the panning
of the signal. AUDIO MOD IN QUALITY set’s the quality of the audio
modulation casued by AUDIO MOD IN input signal.
AUDIO MOD IN RESO adds resonance to the modulation.
DATA
Use DE-9 Data connection cable to hook up the programmer. The
programmer unit makes it possible to program a custom LFO
waveshape, add effects and save your settings.
PROGRAMMER
AUDIO MOD IN: Input mod signal will modulate the audio. It works
like a vocoder where the normal AUDIO IN is the carrier and this
input is the modulator.

Thank you for supporting
Ekssperimental Sounds Studio!
Ekssperimental Sounds Studio is a one
man project driven by the passion for
experimental electronic sounds, new
and old synthesizers and music gear.
As a Reason user since 2001 it truly is
a dream come true to nally be able to
create my own synthesizers and effects
for the Reason rack.
Thanks to all of you who buy my
products I can continue to learn and
develope more fun and inspiring
devices for our beloved rack.
I hope you will enjoy INDSTRLZR!
Cheers,
