Playback tempo -- is there a min/max?

I ask because I’ve got a breve=132 then a rit. to half that. When I look at the Tempo line in the key editor, I see a “Range max” and a number box. Should i take it that the number represents crotchet beats?

That’s 1056 crotchets per minute. I’d tend to say that is impossibly fast for anything. What is this about/for? Is my multiplication completely wrong?

I make it 528, but they aren’t playing/singing crotchets; time sig is 3/1, medieval like

I suspected as much - medieval.

Isn’t a breve 8 crotchets? 132 x 8 = 1056. No?

Pretty sure Dorico tempo is always in crotchets. One of those things they assume is obvious and not explicitly labelled or in the manual. I don’t believe you can alter the default tempo unit.

Back in 2024 Daniel said “Dorico has a maximum tempo of quarter = 500”.
(Equivalent to breve = 62.5)

Yes, the tempo lane always shows the crotchet equivalent.

Which is 8 crotchets in a breve, as I said, unless I am going nuts. A breve is a ‘double whole note’, right?

Even if you are singing in breves for medieval notational purposes, 132 is still unbelievably fast. Are you sure there is not some mistake here? I’m sure people never sang that fast.

Have you got a MS or facsimile you can show us?

You asked about minimum. Amusingly, it can’t be zero! But I suspect anything 0 < 1 <= 500 is allowed.

Ach, you’re right; it is semibreve=132. The key editor box lets me rack it up to [q]=528, but I had to adjust it manually.

Nothing amusing about it: a tempo of zero is stopped.

@benwiggy If stooped is a tempo! What is the sound of one hand clapping?

The sound of intent.
(Mu!)

Wind…

Related, perhaps, to the speed of a lone ball in otherwise empty space.

The sound of one hand clapping depends on your skill. Mine is barely audible, but other people can make a decent sound: https://youtu.be/qwoq3QBaQAY?si=WVR9zE79QkPtB57A
