What's the difference between the basic model Cirklon and the CVIO model Cirklon?
The basic model Cirklon (1250 Euros) can connect to any MIDI compatible instruments with standard DIN sockets. It also features a USB-MIDI slave port for connection to PC, Mac or USB-MIDI host devices, and a DIN Sync output port for control of suitable equipment.
The CVIO model Cirklon (1470 Euros) extends these capabilities to include control of analogue synthesisers via multiple CV (control voltage) and gate outputs. There are 16 high-resolution CV outputs and 8 gate outputs via a 25 way connector on the rear panel.
The CV outputs support V/octave and Hz/V modes plus portamento/glide and micro-tuning options. The gate outputs can be configured in 5V v-gate or S-trig modes.
A break-out box (BOB) is required to connect analogue equipment to the CVIO model Cirklon. Our BOBs provide sockets for each of the 24 outputs carried by the analogue connector.
Can the basic model Cirklon be upgraded to the CVIO model?
A basic model Cirklon can be upgraded by fitting a CV board inside the Cirklon. The CV board can be purchased via our online shop.
Fitting the CV board yourself is quite straight-forward if you have basic technical skills - no soldering is required.
This tutorial video demonstrates the installation procedure.
What type of breakout boxes do you sell?
Our breakout boxes (BOBs) are available with either 3.5mm or quarter-inch (6.35mm) sockets, in desktop or rackmount form.
We also offer a 14HP Eurorack BOB module with 3.5mm sockets.
On rackmount BOBs the analogue bus socket can be fitted to either the front or back of the BOB, with a blanking plate in the opposite position.
A cable to connect the BOB to the Cirklon should be purchased separately from us.
2 metre, 3 metre or 5 metre round BOB cables are available .
We also sell a 50cm flat ribbon BOB cable which is ideal for when the Cirklon and BOB are rackmounted together.
If you want to make your own break-out cable here’s the pin-out diagram:
