OUR SECOND COMPLETE SYSTEM, AS A COMPLEMENT TO THE LAB SYSTEM 84, IS THE LAB SYSTEM SEQUENCER.

HOUSED IN A BLACK POWDER COAT ALUMINUM ENCLOSURE WITH A STURDY VINYL TOP HANDLE — KEEPING PORTABILITY AND DURABILITY IN MIND.

IT IS POWERED BY OUR PROPRIETARY SWITCHING POWER SUPPLY AND CUSTOM DISTRIBUTION BOARD.

THE SYSTEM FEATURES THE FOLLOWING THREE MODULAR UNITS:

• PLEASE NOTE OUR CABLES ARE KEYED TO EACH MODULE, THE -12V RED LINE IS ALWAYS DOWN. USE OF ANY OTHER POWER CABLE IS AT YOUR OWN RISK AND MAY VOID YOUR WARRANTY.

THE EM-74 CHRONOGRAPH | ANALOG CV & TRIGGER SEQUENCER FEATURES:

• THREE ROWS OF 8-STEP C.V. GENERATORS WITH INDIVIDUAL CV RANGE AND GLIDE CONTROLS FOR EACH ROW.

• VINTAGE KEYBOARD KEYS AS BUTTONS, A UNIQUE DESIGN ELEMENT THAT FUNCTIONS TO PROVIDE EASE OF ACCESS AND SPEEDY RESPONSE TO THE ESSENTIAL FUNCTIONS: START/STOP,  STEP, RESET.  EACH BUTTON WITH A DEDICATED CV INPUT.

• AN INTERNAL CLOCK OSCILLATOR WITH A FREQUENCY RANGING FROM .05 HZ TO 45 HZ.  THE INTERNAL CLOCK MAY BE MODULATED VIA THE ONBOARD C.V. INPUT.  THIS OSCILLATOR MAY ALSO BE ROUTED EXTERNALLY VIA THE CLOCK OUTPUT.

• TRIGGER ASSIGNMENT AND POSITION VISUALIZED ALONG THE BOTTOM ROW OF THREE-POSITION (ON-OFF-ON) MINI SWITCHES. EXTERNAL CLOCK INPUT WITH MANUAL STEP FUNCTIONALITY.

• AN EXTERNAL CLOCK INPUT FUNCTION, WHICH ALLOWS CHRONOGRAPH TO BE UTILIZED AS A ‘GRAPHIC’ VOLTAGE-CONTROLLED OSCILLATOR—THEREBY ENABLING THE USER TO CREATE AND MANIPULATE COMPLEX WAVESHAPES.

• VOLTAGE-CONTROLLED ‘SKIP,’ WHICH IS BUILT ON A SEPARATE INTERNAL HIGH-SPEED OSCILLATOR. THIS SECONDARY VCO MAY BE MODULATED VIA THE ‘EXT. TRIG IN: SKIP’ INPUT, IN ORDER TO CREATE COMPLEX GLITCH PATTERNS. THE HIGH-SPEED OSCILLATOR MAY ALSO BE USED TO PRODUCE RANDOMIZED AND/OR HIGHLY CHAOTIC RHYTHMIC EVENTS. (THIS SUB-CIRCUIT DESIGN WAS INFLUENCED BY THE SKIPPING FEATURE FOUND IN THE VENERABLE ARP 1601 SEQUENCER).

• LED LAMP INDICATORS FOR EACH STEP POSITION.

• LED LAMP INDICATORS CORRESPONDING TO THE THREE TRIGGER SECTIONS.

• A VERSATILE FREQUENCY DETECTOR AND DIVIDER CIRCUIT, WHICH GENERATES SQUARE WAVE SIGNALS DERIVED FROM

• THE FREQUENCY TRANSMITTED TO ITS SIGNAL INPUT JACK.

• END PULSE OUTPUT FUNCTIONALITY.

EM-77 M.G.T. SEQUENTIAL SWITCH

EM-77 M.G.T. IS A BI-DIRECTIONAL SEQUENTIAL SWITCH, WHICH ALLOWS THE USER TO ROUTE EITHER AUDIO OR C.V. SIGNALS IN A SEQUENTIAL MANNER.

THIS PROCESS CAN BE ACCOMPLISHED BY ROUTING ONE SOURCE TO TWO, THREE OR FOUR DESTINATIONS (1:2, 1:3, 1:4).  ALTERNATIVELY, TWO, THREE OR FOUR SOURCES MAY BE ROUTED TO ONE DESTINATION (2:1, 3:1, 4:1). 

THE SWITCHING CIRCUITRY MAY BE TRIGGERED BY APPLYING A CLOCK SIGNAL, OR MANUALLY VIA TACTILE PUSH. 

FOR ENHANCED CONTROL, M.G.T. ALSO FEATURES ONBOARD ‘RESET’ AND ‘INHIBIT’ INPUTS.  THE LATTER ‘INHIBIT’ FEATURE ENABLES THE USER TO FREEZE AND UN-FREEZE THE BINARY COUNTER.

EM-75 D.F.A. CLOCK DIVIDER

EM-75 D.F.A. CLOCK DIVIDER IS A FREQUENCY DETECTOR CIRCUIT, DESIGNED TO DERIVE DISPARATE DIVIDING FACTORS—BASED ON THE PRESENTED ‘DIVIDEND’ VARIABLE.  THE

‘DIVIDEND’ VARIABLE MAY TAKE THE FORM OF A CLOCK, TRIGGER OR GATE SIGNAL.

THE MODULE THEN PROVIDES SIX ‘GENERATING QUOTIENT’ OUTPUTS (AT FACTORS OF 2, 4, 8, 16, 32 & 64, RESPECTIVELY).  THESE QUOTIENTS MAY BE USED TO

GENERATE NEW FREQUENCIES AND/OR COMPLEX PATTERNS FOR POLYRHYTHMIC BEAT-MAKING.  THE ACTIVATED QUOTIENTS ARE VISUALIZED VIA LED INDICATORS.

THE LAB SYSTEM 84 CASE IS AN 84 HP / 3U ENCLOSURE EXCLUSIVE TO THE LAB SYSTEMS (84 SYNTHESIZER AND THE SEQUENCER). 

THIS RUGGED ALUMINUM CHASSIS IS MADE OF 4.00 MM ANODIZED ALUMINUM PANELS, IN A POWDER COATED BLACK.  DESIGNED WITH PORTABILITY IN MIND, IT INCLUDES A STURDY 60’S VINTAGE TOP HANDLE MADE OF VINYL WITH NICKEL HARDWARE.  THE 84 HP/3U MOUNTING RAILS INCLUDE 52 SLIDING NUTS FOR EASY MODULE POSITIONING.

INSIDE THE CASE IS OUR OWN POWER DISTRIBUTION BOARD WITH SEVEN 16-PIN MALE HEADERS AND OUR PROPRIETARY SWITCHING POWER SUPPLY.  

ON THE BACK WE HAVE AN ENGRAVED “LA” LOGO,  AN I/O POWER SWITCH, AND THE INPUT FOR THE 19 V/AC ADAPTER (ALSO INCLUDED).

IN ADDITION, EACH MODULE HAS ITS OWN KEYED IDC RIBBON CABLE.

• IDC POWER IN: 10-PIN KEYED FEMALE HEADER INTO MODULE.

• IDC POWER OUT: 16-PIN KEYED FEMALE HEADER INTO POWER DISTRIBUTION BOARD.
