Where these facts come from

How they were read

ONE DOCUMENT, A QUICK START GUIDE, AND THE PRODUCT PAGE LISTS NO OTHER. The page embeds its own download list as data, and the list has three items: "Quick Start Guide" (product_page), typed Manual, and two builds of "Synthtribe App" (product_page), typed Software at version 3.2.4, one for Windows and one for mac. So the page lists no user manual, no firmware and no MIDI document, and that is read off a list and not concluded from a search. behringer/model_d records a user manual on its own page, so this maker does list one where it has one.

THE PAGE CLAIMS A COMPREHENSIVE MIDI IMPLEMENTATION, AND BEHRINGER PUBLISHES THE CHANNEL AND THE SOCKETS, AND NO MESSAGE. The page embeds a list of eighteen features as well, and the last is its only word on MIDI: "Comprehensive MIDI implementation with MIDI channel and Voice Priority selection" (product_page). Both special editions' pages end their lists with the same sentence (blue_marvin_page, gray_meanie_page). The guide accounts for half of it, the channel. The word priority is in none of the three guides, and the nearest thing they describe is the switch between one voice and two. So a selection the maker advertises is set out nowhere the maker publishes, which is one more reason this file does not say that there are no controllers.

NEITHER LIST IS IN THE PAGE'S VISIBLE TEXT, WHICH NEVER NAMES MIDI. The downloads and the features are data inside the page's script, behind tabs the visible text only labels, and what is cited here is an extraction of that data. That is how behringer/edge cites its page's download list. behringer/td_3 meets the same stock words on its pages, a MIDI channel and Voice Priority selection, and describes them without quoting, the copy it cites being the page's visible text.

THE GUIDE'S ENGLISH NAMES MIDI ON THREE PAGES. It is 62 sheets: a cover, then two printed pages to a sheet, then a back page, in eleven languages. Its English is safety, warranty and compliance text, one section headed Step 1: Controls, which is a list of a hundred numbered panel items, and the specifications. MIDI is named on the back panel's page (guide p. 18) and on two pages of the specifications (guide pp. 111, 113), and on no other English page.

FOUR ITEMS OF THE BACK PANEL ARE THE WHOLE OF IT. The channel: "MIDI CHANNEL SWITCHES – These 4 switches allow you to set the MIDI Channel number from 1 to 16 (see the table printed in this document or refer to the silk-screened switch matrix printed on the back panel)." (guide p. 18), and the table is sixteen pictures of the four switches, each over its number. By the pictures the levers count in binary from the left, and none raised is channel 1. No sentence says which position is on and the table has no legend; the picture of the back panel above it letters ON DIP over the four levers and 1 2 3 4 under them, so by that lettering a raised lever is on. The input: "MIDI IN – This port receives MIDI data from an external source over a 5-pin DIN connector." (guide p. 18). The through socket, in a sentence printed as it stands: "MIDI THRU – This port uses a 5-pin DIN jack is used to pass through MIDI data received at the MIDI IN jack." (guide p. 18). And the USB port: "This synthesizer will show up as a class-compliant USB MIDI device, capable of supporting MIDI in and out." (guide p. 18). The specifications add a line for each connection, "MIDI in / thru 2 x 5-pin DIN, 16 channels" (guide p. 111) and "USB (MIDI) Type B" (guide p. 111), and name the switches again as 4 x DIP switches (guide p. 113).

NO TABLE OF MIDI MESSAGES, SO NOTHING FOR A CONTROLLER TO BE MISSING FROM. No sheet of the guide, in any of its languages, prints a controller number, or any of the words such a table would: control change, program change, system exclusive, pitch bend, aftertouch, note on and note off among them. Velocity is not in its English either; its Spanish, Portuguese and Italian print their word for it, each time for the speed of an oscillator, a clock, an envelope, a delay, a glide or a switch, and never as a MIDI term. behringer/td_3 says none out of a quick start guide because its guide carries such a table and the TD-3-MO's copy of that table carries a controller. behringer/edge leaves the field unset because its guides carry no table, and this guide is the EDGE's case. So control_change is unset here. The same silence is why velocity, pitch bend, aftertouch, program change, system exclusive, MIDI clock and transport are not recorded: none is denied and none is stated.

IT IS PLAYED FROM A KEYBOARD IT DOES NOT HAVE, AND NO SENTENCE JOINS THAT KEYBOARD TO MIDI. The guide speaks of the keyboard throughout and means another instrument's: "The Keyboard section determines how the built-in Low Frequency Oscillator (LFO) unit works with an external keyboard." (guide p. 14). The source at MIDI IN "will commonly be a MIDI keyboard, an external hardware sequencer, a computer equipped with a MIDI interface, and so on." (guide p. 18). Inside the instrument the keyboard is a voltage: "The keyboard control voltage is available as a pre-wired connection wherever you see this label:" (guide p. 14), over a box lettered KYBD CV, and the picture of the oscillators shows that box under the first FM CONTROL jack of each of the three (guide p. 11). Each oscillator has a switch for it, "In the AUDIO position, keyboard control is enabled." (guide p. 10), and the one English sentence with the word pitch in it is the keyboard section's: "The Portamento function allows one pitch to change gradually to a second pitch a predetermined rate." (guide p. 15), printed as it stands. A keyboard's voltage can be brought in at a jack too, an input of the Voltage Processor's first inverter: "KYBD CV – This input is optimized for control voltage signal from a keyboard." (guide p. 17). But no sentence says in terms that a MIDI note plays a pitch, or what the instrument does with anything that arrives at MIDI IN beyond passing it through. addressing: pitches is a reading: of an instrument with a MIDI input and a channel to set, whose guide names a MIDI keyboard first among what is plugged into that input, and whose three oscillators are wired to follow a keyboard's voltage.

ONE VOICE OR TWO IS A SWITCH, AND THE SECOND VOICE IS A CONTROL VOLTAGE AT A JACK. "VOICE MODE(MONO/DUO) – Use this sliding switch to determine whether the keyboard plays one voice at a time (MONO) or two voices simultaneously (DUO)." (guide p. 14). What DUO adds is an output: "UPPER VOICE – This output sends out a control voltage based on the highest note being played on the keyboard while in DUO voice mode." (guide p. 14). No sentence says the upper voice is wired to an oscillator, and none says how the second note comes to sound; no box under the oscillators' jacks in the picture of them is lettered for it (guide p. 11). The specifications print the switch again, "Voice mode: mono / duo, selectable" (guide p. 113), give "Number of voices Multiphonic" (guide p. 113), and list one filter and one amplifier. So voicing_modes is one and two. polyphony is not recorded: the specifications give a word, Multiphonic, and no figure, and a sliding switch has no default. Whether two notes are to be called paraphonic is left unsaid. The word is in no guide. The three oscillators are pre-wired into the one filter, "pre-wired connections from Voltage Controlled Oscillators 1, 2 and 3 into the VCF block" (guide p. 10), and no sentence says which of them plays which note.

THE TWO SPECIAL EDITIONS PRINT THE SAME FOUR ITEMS. The guide itself says what one of them changes: "NOTE: 2600 uses a digital reverb, while BLUE MARVIN features a real, on-board spring reverb." (guide p. 14). The BLUE MARVIN's guide and the GRAY MEANIE's each print the four back-panel items word for word as this one does (blue_marvin_guide p. 18, gray_meanie_guide p. 18), and each of their pages lists a guide and the same two builds of the application (blue_marvin_page, gray_meanie_page). Every other line a field here rests on is in both as well: the voice switch's item and the upper voice's (blue_marvin_guide p. 14, gray_meanie_guide p. 14), and the specifications' lines for the sixteen channels, the voice mode and the number of voices (blue_marvin_guide pp. 111, 113, gray_meanie_guide pp. 71, 73). So by its own guide each edition would be recorded as the 2600 is. This file is not offered as either's, and whether each wants a definition of its own is not settled here.

THE APPLICATION WAS NOT RUN. The page offers Synthtribe and the guide never mentions it. By behringer/edge's account the same application sets that instrument's channel and other parameters; whether it reaches the 2600, and what it would show, no document says. Vendor software is not installed to read a specification.
