|| Polymath is 'Fully Modular'
- in the sense that every thing can be detached and repatched. It
doesn't have to be used as a 'poly synth' or a traditional 'mono
synth'. It can be repatched to do whatever you wish. Circuits can be
isolated and used in conjunction with other modular synths or synths
such as the Telemark.
The position of important patch points have been placed close together,
where possible, so shorter patch leads can be used that won't obscure
too much front panel. For example, Mixer Out jack is placed next to the
VCF Audio In jack. This means that it can be patched up to be a
mono/poly synth with a minimal amount of cables or front
Some voltages are pre-patched in a sense, via quick and easy to use
front panel pot's or switches, but they can all be effectively removed
from the circuit by setting them to 'zero'
Some Additional Cool Features
Detune - This flattens VCO2 and sharpens VCO4, so that in Unison mod
you can easily 'fatten' the sound.
There are 'global' PWM and Pitch Modulation controls, so that, if for
example, you want to apply vibrato to all VCOs equally, you can do that
with one cable rather than 4.
Spring Reverb - instantly transforms the sound. This doesn't have to be
patched in as a traditional effect, at the end of the signal chain.
Sounds cool when inserted between the Mixer output and VCF input."
What is Paraphonic?
Ideally, for full 'polyphony' in an analogue synth you effectively need
a complete analogue synth per voice. That is VCO, VCF, EG and VCA. For
an analogue synth this is an expensive affair. So a few synths were
Paraphonic (for example the Korg Monopoly). This mean that you still
had a VCO per voice, but they shared a single VCF, VCA and EG. This
provided cost and space savings.
Why is Polymath using the paraphonic method?
I chose to go Para' not so much to save money or space, but because to
make a truly polyphonic modular synth becomes a patcher's nightmare. I
know, I have done it using discrete modules. You end up with a sea of
patch cables - and you can barely get to any of the synth's knobs. I
wanted Polymath to be a fully patchable, versatile analogue synth, as
well as being polyphonic - not just a one trick pony. Going Para' was a
good comprise, allowing it to both be manageable (patching wise) and
There's another reason it's Paraphonic
The way synth's such as the Korg Monopoly handle polyphony give it it's
own kind of sound (that can't be put into words here). By making
Polymath a paraphonic synth gives it that same sound characteristic
that few other synths have.
In poly mode, as you press and release a single key, the synth will
cycle through its four VCOs. If you have a slightly different setting
on each VCO, as they cycle, you will get a different timbre as each
note is played. This sounds pretty amazing - something you will be
familiar with if you are lucky enough to own a Mnopoly, Oberheim 4
