Want to hear something strange?
Everithing you put into the AM IN can be a sourprise. But try to patch the A Rear output into the AM IN.
Then give a saw to A, all serial, then let the three Emphasis go.
Try some different mode combinations and prepare your soul to a blind-date with the just uncaged, thirsty
and barking Demon of the Cursed Amplitude Modulation.
THE COMPONENTS [ 19 ]
• MONO : it's the classic label for a single audio signal. Because of the unique interior layout of VERTICE this
output port is also the
PARALLEL
(aka
∑
) out. You can better understand this method by looking the SIGNAL
FLOW section of this manual ( page 15) or the ∑ /STEREO/SERIAL description ( page 35
• STEREO : unlike the most analog filterbanks in the market the VERTICE provides a stereo modality which you
can activate using this port and the
MONO
output at the same time. Then you need a Left input inserted in the
Filter A audio input and a Right input inserted in the Filter B audio input. If the ∑ /STEREO/SERIAL switch in the
front panel is set to
STEREO
you can use the VERTICE as a
true stereo
unit with 12dB/oct slopes for each channel.
The INPUTS and OUTPUTS on the rear panel
• A and B: these two ports carry the corresponding filter audio signal directly taken from the
last point before the related routing switches, and often giving a 15Vpp signal level. They
come out at a more high level than a standard CV, and for that reason they are useful in both
audio and CV applications, like using an audio signal to command some external moudule.
This is an uncommon possibility and often lead to a whole new meanings of the word "craziness": we
strongly recommend the use of these two ports in order to create audio feedback into the signal path. If you
never used these two ports you are missing one of the best chances Vertice can offer to be astonished and
deeply touched by it. It is also highly recomended to patch these ports into your patch-bay to obtain more
comfort during patching.
E.g. you may want to create something like this:
Audio into B, B into C, C to output. Then you can take the B signal and route it into A, which is also going into
B. In this way you just made an audio feedback between B and A-to-B, and if it sounds weird on paper try to
imagine this patch in the real world.
You can also route A into A itself! In this case, WITHOUT the presence of ANY OTHER EXTERNAL SIGNAL, you
often may obtain a sort of strange unstable VCO when the pitch is "determined" by all the Cutoff frequencies
involved and audio levels, and with a waveform "casually regulated" by other settings like Emphasis or
Mode (of all the various filters involved). And there is plenty of other routing possibilities, like the "Drilled-
by-the-Dentist Cat" and the "Domestic Whale". You have to try it. For more info page 54.
• Mono/Par and Stereo/Ser : born simply to give extended patching simplicity, avoiding the two fixed output
cables constantly dangling from the panel, these two ports are simply copies of the outgoing main audio
front ports. Nothing more, but nothing better to create other really weird patching possibilities, feedbacks
and melt-mind puzzles like: "but, what? who did, wait, what?!"
We really recomended to try also this two sockets, especially in front of some friends. :)
- if too much voltage level is injected into this port you can shut-up your VCAs. This side-effect often happens
when doubling the EG signal, routing it both to VCA (via switch on the panel) and to AM input (from rear EG
out socket). This is a not-dangerous-but-still-unhappy situation for the VCAs, so don't keep your Vertice a
long time under these settings. Also because, by-the-way, if set-up like this it can play nothing but silence
(VCAs are in "alarm mode"). To restore the normal situation just lower the incoming signal from the AM or,
in the specific previously mentioned case, the double EG, just don't double your EG. One single internal EG
signal is enough to obtain all possible sonic nuances from your VCAs. We have told you so...
