Midi Wiring / How it works
- MIDI has a Master and more slaves that are chained. There are 3 MIDI Jacks: IN, OUT, THRU
- Being Master means to send the timing "MIDI Clock" to the chain.
- the chain transports the signal from IN to THRU.
- the Midi OUT sends MIDI Notes and Controllers (Modulation Wheel, Parameters) in real time but will NOT be integrated into the IN-THRU chain. if you want to do that you need to Merge the signals: Midi Merger
- The Master can be a computer or Sequencer or even a Keyboard that will control and synchronize all following devices if connected to the chain:
Devices - connections: DEVICE1 MIDI OUT --> MIDI IN (Device 2) --> MIDI Thru --> MIDI in (Device 3) -->..
Midi Merger + Patchbays
what use? Midi Merger: if you eg have 2 sequencers chained via thru you can use the clock via thru OR the midi out.. so if you want both you need to merge the midi ports digitally, same with controlling 1 synth from 2 keyboards or sequencers..
Midi Thru Box: Some synth do ont have midi thru , also you can use it to increase the performance eg multiple drummachines & sequencers to directly get their clock signal from the thru box instead of XX instruments in a chain..
Midi Controller: Is a device that allows to change Parameters on Synths in realtime, lots of them also have a keyboard and other "input" sensors etc..
- Pilarik & Elger PMM88 + PMM44 (4 / 8 Ports) - very flexible
- Waldorf Midibay
- Roland UMM88
- Doepfer MMR4/4
- Edirol UM550
- Any modern 8-Port-Midi-Interface like Emagic (now Apple) AMT8 + Unitor 8, Esi, Motu timepiece series and many more..
there are lots of cheap thru boxes and merger like m-audio (and all companies bought by m-audio like midiman etc.)
MIDI format sieht so aus: / Midi Format looks like this
the first dada is just binary, hex and decimal values, all 7bit (128 values) - longer / larger controller ranges often use NRPNs (cascaded controllers) to address the parameter and raise the resolution of each parameter like the 16384 steps on the Alesis Andromeda etc.. Sysex has NO channel but a device ID which makes it possible to address more than one instrument (so you can address lots of (eg. TG77's..)..
das erste sind einfach die binären, hexadezimalen und dezimalen werte und danach die info über noten, CC oder andere informationen.., dann die notennummer und velocity.. alles in 7 bit , also 128 schritte max.
längere (controller)datenpakete werden zB per NRPN verpackt, wie etwa beim Alesis Andromeda A6, der somit eine auflösung pro knopf 14bit = 16384 schritte hat..
hoffe das spricht für sich selbst: und sagt vorallem eins aus: alles geht doch eher "seriell" über das kabel!!.. daher: sysEx ist entsprechend einzustufen , besonders bei synths , die nur SysEx parameter empfangen!!.. denn sie "knallen" den ganzen kanal voll.. um genauer zu sein, das KABEL!, denn sysEx ist ja kanalunabhängig , sondern einfach eine andere adresse.. (ab F0 hex)!!

SYSEX - SYX + MID
- Note: System Exclusive (data dump)
2tes byte= Hersteller ID danach folgen einige bytes (herstellerabhängig) beendet mit EOX. 2 byte = manufacturers ID followed by model numbers and ending with EOX.
note: SYX files are NOT the same as MID files, use sysex (mac) or midiox (pc) to dump them from/to a computer..
achtung: es gibt reine .SYX files, (manche hersteller liefern neue betriebssysteme so aus) die genau nur DIESE daten enthalten.. wie man damit umgeht im software/computerbereich: hier
Das MIDI Manifest - Midi 2?
Dauerhaft sollte man nun von den sehr sich ausruhenden Herstellern zum Thema Midi.
Was gebraucht wird: - Computerintern und zwischen 2 Computern sync, Controller, Parameter, Noten etc. zu transportieren - Dasselbe nach aussen - Schnell und unproblematisch - Mind 16 - 32 bit für Controlleradressierung bzw. Parametertiefe (65535 Controller mit Werten bis 65535 = 16bit) - Übertragung der Parameternamen und Werte - Prioritätenreglung (Noten, Controller = Prio1, Parameternamen Prio2, Sync: Prio0 etc..) Vorteile für Industrie - Geräte verkaufen können - Analoge können neu umgerüstet werden, neue können auf die lächerliche 7Bit-Auflösung verzichten und keine "Workarounds" mehr.. Liebe Industrie, wollt ihr kein Geld verdienen? Setzt euch zusammen, macht eine schnelle, gute und zeitgemäße Norm, die langfristig funktioniert und bietet auch Midi2->Midi Interfaces an - Dann verkauft ihr ALLE die nächsten 2 Jahre mehr.. Danke.
THE MIDI MANIFESTO..
Manufacturers!! You want to sell more? Why not coming together make a Standard and then sell much more, especially the next 2 years will bring you a lot of chances to sell things..
what is necessary:
- computer to computer and internal things to get them synched etc.. - up to date speed and scaleability - no less than 16-32 bit Resolution and Addressing (no less than 65535 Steps / Parameters possible then without Sysex!!) - add parameter names (cool for controller boxes and software - plugins and box will sync up and simply show all parameters.. thats how most ppl want to work.. put them up ordered by use OSC.. Filter.. ..Sequencer step 1-128.. - Priority for tempo sync, notes and a also controllers in the second place, parameter names when there is time..(idle or manually).. - no more sysex needed then or at least rare then.. - analogue synths can be retrofitted with better resolutons and more controllers.. so, why not? tell me?.. will bring you a lot of new products sold..
