Moon 553 Midi-to-Clock Interface - confusing scale

Author Moon 553 Midi-to-Clock Interface - confusing scale
Sugarfree
Do I read this wrong or the scale on this module is mislabeled?

Since midi clock clock runs 24 ticks/pulses per quarter note:

1 tick = 1/64 triplet
2 ticks = 1/32 triplet
3 ticks = 1/32
4 ticks = 1/16 triplet
6 ticks = 1/16
8 ticks = 1/8 triplet
9 ticks = 1/16 dotted
12 ticks = 1/8
16 ticks = 1/4 triplet
18 ticks = 1/8 dotted
24 ticks = 1/4


and here's the scale on the Moon:

1/96 > this is 1/64T (1 tick)
1/48 > this is 1/32T (2 ticks)
1/32 > 3 ticks
1/32D > this is wrong, this one has to be 1/16T (4 ticks), 1/32D would need to be 4.5 ticks, which is impossible
1/16 > 6 ticks
1/16D > is it really 1/16D (9 ticks) or 1/8T (8 ticks)
1/8 > 12 ticks
1/8D > is it really 1/8D (18 ticks) or 1/4T (16 ticks)
1/4 > 24 ticks

hmmm..... I guess I never really thought about it much so I'm not sure. I would just adjust things until I got the rate I wanted. I'll have to pay attention more next time I use mine.

Perhaps it has the ability to interpolate between clocks?

I'm pretty sure it's just a clock divider, but I could be wrong.

I think I may have stumbled on where the confusion may be... (but I could be wrong)

You stated right from the beginning that MIDI Clock runs 24 ticks/pulses per quarter note. Right from the data sheet from .pdf of the M553, it states the "STARTING" 1/96 (original MIDI tempo) and not 24, effectively, Gert had quadrupled the 24 note pulses into the 96 for better divisibility for the clock...

again, I am just guessing here... and mine isn't powered up at the moment to "test the theory" but the math seems to work out, 24 x 4 = 96 seriously, i just don't get it thumbs up

no, the pdf you quote actually says:

Quote:
The MIDI clock (MIDI real time message) has a native resolution of 1/96 notes (24 ticks per quarter note)


It says: a resolution of a 1/96 note, not 96 ticks per quarter note.

a 1/96 note (AKA 1/64T d'oh!) means 96 notes per whole note, same as 1/4 means 4 notes per whole note.

so it is 24 ticks per quarter note and 96 ticks per whole note,
and yes, 24 ticks * 4 = 4 quarter notes = 96 ticks

OK, I get it now... quavers and all suchlike:

Specialist: Give her six quavers, then pause.
Technician: She sent us four quavers, a group of five quavers, a group of four semi-quavers...
Walsh: What are we saying to each other?
Laughlin: It seems they're trying to teach us a basic tonal vocabulary.
Specialist: It's the first day of school, fellas. Take everything from the lady. Follow her pattern note for note.

dang it, and here I thought I was being all smart and intelligent... Mr. Green d'oh! I literally "missed" that part, (last night, Vodka "may" have had some interference)... woah

... well then, I am not going to be of much help for now, all of my modules are waiting for new cases, and wiring... it'll be awhile before I can test anything. seriously, i just don't get it seriously, i just don't get it seriously, i just don't get it seriously, i just don't get it seriously, i just don't get it
