The SQ-1 Card for EMS
Synthi A / AKS / VCS3
If you do however and a refund is needed, I will
discount the fees because Paypal now keeps the fees in
case of refund.
Rather contact me to
arrange another solution.
The SQ-1 Card adapts the great small Korg SQ-1 sequencer
and adds easy plug and play CV/gate facilities to the
The card simply plugs directly into the 8 pins Jones
"keyboard" socket and is powered by the Synthi, no
cables no connector.
For use with a VCS3, the Jones plug can be mounted onto
the top side of the PCB but an adapted umbilical cable
with swapped connections is requested, the standard
cable won't work.
Warning : the card's power consumption is 155mA on the
Synthi's +12V power rail, which is too much load for a
It should never be plugged into a MK1 unit, this would
fry its PSU. I assume no liability in case of problem
(anyway, it can be repaired, no worries).
In several MKI units (including my own one) I added an
extra PSU to power a KS, it is ok for the SQ-1 Card and
I'm happy to share the how to if needed.
Another solution is to power the SQ-1 via its USB port
and omit the power circuitry on the card.
for best stability and solidity
All the nice features of the SQ-1 are
working with the Synthi.
The SQ-1's CV outputs A and B are routed respectively to
the Synthi's input channel 1 and 2. Thanks to a
multiturn trimmer, the CV can be scaled to get equal
temperament when the Synthi's input level pot is set to
10, therefore no more tricky adjustment is needed to
control the Synthi 1V/oct.
A good working and properly calibrated Synthi tracks in
tune over 5 octaves with the SQ-1 Card.
The Synthi's envelope can be fired by either the SQ-1's
A or B gate, a 3-position switch replaces the SQ-1's
former "littlebits OUT" :
left is gate A, center is no gate, right is gate B.
When the SQ-1 is turned off, its CV/gate output jack
sockets can be used as inputs to control the Synthi with
another controller enjoying its equal temperament 1V/oct
Small plates mounted to the back lock the Spartanite
case's handle for better stability.
Control other synths
The SQ-1's ins and
outs minijack sockets are still working.
The SQ-1 can control other synths together with the
Synthi via CV/gate or MIDI and sync with other gear as
a slave or as a master via its sync in and out
The DIY PCB + panel set costs 95€ shipped
It includes PCB, panel, Jones connector cover, handle
support and buffer chicklet (I do not supply with other
and build notes
A pre-built SQ-1 Card costs 350€ + shipping.
