There are some positions that VERTICE like so much and other for which is not exactly enthusiastic. In this

section we talk a little about these situations.

THE NATURAL MONO SERIAL

This is the most classic situation: a single audio signal is flowing into the A-audio input and then, via the routing

switches, sent to the sequent filterboard until it reaches the

SERIAL

output. Do not formalize on the

STEREO

label here. In this configuration there is nothing of stereophonic.

This is the starting position to obtain a large range of cutoff slopes:

•

the soft, stable and orchestral-sounding

10dB/oct, obtained with zero

Emphasis

setting

•

the

18-22 dB/oct achieved by an increased

Emphasis

level of two filterboards. A very expressive, unstable

and tonic timbres maker. Just set it over a simple sawtooth and wait for a while: you will notice a slow

morphing irregular wave upon your stable oscillation. This mean injecting

life

into the sound!

•

the

24-26 dB/oct with the three filters involved. Just try to tune the three

Cutoffs

. Strange things can happen

here...

Note that in this description there is

Emphasis

playing a relevant role. Like widely argued before, in this kind

of very early circuit design it's the physics, more than the human think, to rule. So take it for what it is: a very

creative and

real

filterbank, not a perfect surgical instrument. We want the VERTICE sound raw, crazy. We want it

can be astonishing for a long time since you bought it, not just a one-night love. There is plenty of more perfect,

more usable, more inexpressive and money-saving analog and digital filterbanks around here. Why propose the

same stuff again and again? We really hope you will turn on our machine for years not just because you need

LEDs for chrismas tree but because you

love

this little buddy.

Tone Considerations

Natural mono serial is the most common choice for mono bass, contrabass-like tones, very sharp

wobble, low-mid leaders, bass drums and snares and, on the contrary, very classic smooth orchestral sounds.

Different Modes in Serial Configuration

Obviously there is not only the

mode. Feel free to use any of the three modes in any filterboard. But

remember the seriality of this configuration, like the sequent notation try to explain.

This is a serial mode!

It means there are subsequent cuts, in most cases on the same cutoff frequency. So it’s normal if the

B or C-Cutoffs in some configurations seems to not work, especially if they are set in different

Mode

settings (LP, BP or HP). There is nothing broke: they only try to work on a silent part of the timbre, just erased

by the previous board. Use these possibilities to push your creativity behind the common sense line, or die

trying it. In the VERTICE there is always a distortion somewhere you can use to really re-invent the sound,

boosting the Emphasis scream tendencies into really mad Edvard Munch themes...
