MIDI Notes, correct string?

i will be using MIDI Notes on an Ion and have a problem understanding the hex numbers. i read the entry in the onboard help file: 93 45 7F is supposed to be Channel 3, Note A3, Full Velocity. i understand 45 and 7F, but how is hex93 (or dec147) Channel 3? what would be Channel 1, hex91 (dec145)?

thx, ueli

  • Yes, channel 1 would be 91.

    Explaining why 93 is why it is:

    The first hex set is a combination of two four bit chunks - the MIDI Note ON command (in binary - 1001, which equals 9 in hex) and the MIDI channel (0011 - which equals 3). Similarly, MIDI Note OFF would be 83 (MIDI Note Off = 1000, which equals 8 in hex).

    Does it make sense? Let me know and I can try to rephrase.

    (Just to be clear - the Ion doesn't receive MIDI notes data, and only transmits strings that are put together in a macro or Execute flag on a cue list -- this MIDI note is going outbound to another device, right?)

     

  • hi hans

    thanks for your fast reply!

    yep, everything clear now (and i'm well aware, that i can only _send_ MIDI Notes). so to be complete: 93 45 7F means Note ON, Channel 3, A3, Vel 127 (=full). Maybe this could be inserted into the onboard help file as well as the manual?

    and preprogramming offline: are there any settings in the shell i have to be aware of? in Setup > Show > Show Control there don^t seem to be any options for MIDI Notes, right?

    thx, ueli

  • ps: just for confirmation:

    Cue 1 Execute MIDI Raw D 145 4 1
    would send MIDI Note ON E(-2) velocity 1 on channel 1?
