Just a mention to folks who are new to VGuitarForums

In thousands of posts All over the site, we mention several acronyms which can be confusing to Guitarists new to the DSP Modeling/ Synth scene : "FTP", "RPI", "COSM" , etc

I'm posting this because I recently had a conversation with another guitarist who had once stumbled upon our site while doing a web search , and he told me:

Quote"You guys at VGuitarForums are too high tech, with all your talk of moving files using FTP ("File Transfer Protocol"),  in and out of your internet guitars!, Id rather just play my real guitar"

so here is the

VGuitarForums Glossary of Terms
DIN Connector
https://en.wikipedia.org/wiki/DIN_connector

A DIN connector is an electrical connector that was originally standardized by the Deutsches Institut für Normung (DIN), the German national standards organization. There are DIN standards for a large number of different connectors, therefore the term "DIN connector" alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., "DIN 41524 connector"). Some DIN connector standards are:
DIN 41524, for circular connectors often used for audio signals

Which one do i need?
For those not familiar with the Roland VGuitar Syetems (VG-8, VG-8EX,VG88, VG-99, GP-10) you need to know this,
it is not a Guitar synthesizer.
It would more accurately be considered a SUPER DUPER effects processor.
A Guitar synthesizer (GR-20, GR-30, GR-33, GR-55 on PCM Tones) can produce more traditional sounds,
like trumpets, piano, drums, violins, organs etc.,
which the Roland VGuitar does not. (Well, it does a few nice ones, but not like a synth)
The Roland VGuitar on the other hand, is  a billion times more sensitive to play feel
and subtleties in your playing than a synthesizer.
Since it works on the sound of your strings, you can do things like
scratch your strings or bang your guitar and you will get sound,
with a synthesizer, the unit will just be confused.
Also, the Roland VGuitar doesn't "track" in the traditional sense of the word.
It is actually processing effects on your actual string sound,
not converting that sound into MIDI data.
Speed metal players have no problem fitting in all those random notes!

Roland Boss Glossary

COSM
https://www.sweetwater.com/insync/cosm/
Abbreviation for Composite Object Sound Modeling. COSM is a powerful modeling technology that Roland premiered in 1995 with the VG-8 V Guitar System, and continues in the newer VG-99 system and GT-100. It enables guitarists to emulate a range of classic and modern guitars, amps, cabinets, and microphones, plus it can produce "futuristic" synth-like tones. Today COSM can be found in keyboards, digital recorders, mixers, etc. It can model rotary effects, different speaker colorations, and can even approximate expensive microphones using just an ordinary dynamic mic. Its name comes from "composite object" because its core function revolves around breaking audio producing or reproducing devices down to their component parts and creating a set of instructions to emulate how these various parts interact with each other to produce a new composite that can be dynamically controlled. Of course, that's what all modeling is, but Roland coined this name to call attention to it.

AIRD :
https://www.bossus.com/blog/2018/04/19/gt-1000-guitar-effects-processor-now-available/#more-15393
Next-Level Performance with AIRD
The GT-1000 debuts BOSS's breakthrough AIRD (Augmented Impulse Response Dynamics) technology, bringing a new level of musical response and flexibility to digital guitar processors. Based on the comprehensive Tube Logic concept behind the acclaimed Katana, Waza, and Blues Cube amplifiers, AIRD is a complete interactive system that provides optimum performance in every application.



MDP
https://www.boss.info/us/promos/mdp_deep_dive/
With its intelligent processing approach, MDP delivers complex results that are simply not possible with conventional technologies. But this would mean nothing if those results weren't musical, natural, and inspiring to play. To this end, the intelligence in MDP processing is not simply the result of powerful DSP and advanced algorithms; it's intelligence that's guided by the massive experience, knowledge, and unwavering dedication of the engineers at BOSS, as well as the input of the world's greatest guitarists. With this powerful fusion of technology, craftsmanship, and know-how, MDP enables you to express your personal guitar voice like never before.


TUBE LOGIC
https://www.roland.com/global/promos/tube_logic/
With the innovative Tube Logic design philosophy that's at the heart of the Blues Cube series, we've nailed everything that players love about the classic tweed-era tube amps. Not just the sound character, but the organic feel and response as well—in short, every nuance that makes an amp a real musical instrument, one that inspires you and makes you feel great every time you plug in to play.

Quote• Following an international enquiry by the BIPM, which began in 1948, the
10th CGPM, in 1954, approved the introduction of the ampere, the kelvin, and
the candela as base units, respectively, for electric current, thermodynamic
temperature, and luminous intensity. The name Système International d'Unités,
with the abbreviation SI, was given to the system by the 11th CGPM in 1960. At
the 14th CGPM in 1971, after lengthy discussions between physicists and
chemists, the current version of the SI was completed by adding the mole as the
base unit for amount of substance, bringing the total number of base units to
seven.

ACB = Analog Circuit Behaviour. It's the emulation approach used in the System 1 and System 8 synths, and in the Roland Boutique synths


BMC= = ROLAND BMC IC = BEHAVIOR MODELLING CORE DSP
