Kenton Pro-4 - Manual (Page 3)

INTRODUCTION
Congratulations on your purchase of the Kenton Electronics PRO-4 multi channel MIDI to CV converter,
which has been designed to give you maximum flexibility, whilst maintaining ease of use.
The converter has eight completely independent sections - called channels A, B, C, D, E, F, G, & H. Each
channel can be assigned its own MIDI channel, and controlled independently from each other.
The PRO-4 has four independent, MIDI programmable LFO`s that can modulate any of the CV outputs,
and four of the auxiliaries. Each of the CV channels has a portamento function.
There are also many other features designed to make the PRO-4 as flexible as possible to allow as much
control as possible over your analogue synthesizers.
The PRO-4 has a thorough MIDI system exclusive specification for those who wish to do data dumps or
editing from their computer sequencer or generic patch editor.
Please take some time out to read through all of this manual which should hopefully explain all you will
need to know.
THE PRO-4 CHANNELS
CHANNELS A, B, C, & D
These are for controlling analogue synths such as the SCI PRO-1, Roland SH-101, or indeed most other
synths with CV and Gate inputs.
Note, the CV output for controlling the pitch uses the Volts per octave (V/oct) pitch scaling system. This is
the most common system used in analogue synths, as used in Roland, SCI, Oberheim and Moog synths.
Synths such as Korg & Yamaha, (MS20, MS10, CS5), work on a different pitch scaling system. This is called
Hertz per volt (Hz/V). To control the pitch of these synths correctly, the optional four channel Hz/V board
will need to be fitted. This is available as a plug in card. Contact us for details.
Some synths do not have CV, Gate or Filter inputs, such as the TB303. We can fit or supply socket kits for
most monosynths that do not have inputs. Contact us for details.
CHANNEL E, the EDP Wasp port
This channel is a digital output for controlling the EDP Wasp or Gnat synth.
Note, the Wasp responds to three octaves of notes only - on a DX7 or other 61 note keyboard, this
corresponds to bottom C#, to C, three octaves above. The Wasp does not respond to pitchbend - or
indeed any other controls except sustain pedal, which will hold the current note, this is a design limitation
of the Wasp itself.
