JP1
Bus Connector
16 pin connection to suppy/interface board
(compatible to A-100 bus)
connected to
supply/interface
board via ribbon
cable
JP2
CV1 Bus
Connects the CV line of JP1 to the VCO frequency control voltage
input (works in addition to the VCO F socket)
installed
JP3
VCF tracking source
Selects the CV source for VCF tracking (can be turned on / off / half
by means of the Track switch):
Upper position: VCF tracking controlled by the VCO F socket
Lower position: VCF tracking controlled by the CV line of JP1
installed
(lower position)
JP4
VCO tune range
Adjusts the range of the VCO tune control:
installed
Æ
tune range about
±
2.5 octaves

tune range about
±
6 semitones
not installed
(put on one pin
only)
JP5 Audio
Æ
Bus/+5V
Connects the audio output of the voice board to an auxiliary pin of
JP1. Required if socket CV4 is used as audio output.
installed
JP6
VCF Output
pin header with the filter outputs
lowpass (L) - left pin
high pass (H) - center pin)
band pass (B) - right pin)
open
JP7
Socket 7 = LFO1 Reset
Connects socket 7 to the Reset input of LFO1
the left pin is socket 7
the right pin is the Reset input
(can be used e.g. to assign another function to socket 7, in this case
the printing of the housing is no longer valid)
installed
JP8
Socket 8 = LFO2 Reset
Connects socket 8 to the Reset input of LFO2
the left pin is socket 8
the right pin is the Reset input
(can be used e.g. to assign another function to socket 8, in this case
the printing of the housing is no longer valid)
installed
JP9
Socket 2 = PWM
Connects socket 2 to the PWM input of the VCO
the lower pin is socket 2
the upper pin is the PWM input
(can be used e.g. to assign another function to socket 2, in this case
the printing of the housing is no longer valid)
installed
JP10
Socket 4 = CV VCA
Connects socket 4 to the CV input of the VCA
the upper pin is socket 4
the lower pin is the CV input of the VCA
(can be used e.g. to assign another function to socket 2, in this case
the printing of the housing is no longer valid)
installed
JP11
Gate bus
Connects the Gate line of JP1 to the switching contact of the ADSR
Gate socket
installed
JP12
free bus pin -> VCF
Connects an unused pin of JP1 to the switching contact the VCF F
socket. Not supported by the suppy/interface board.
