see my calculation below, amazing how our numbers dont fit exactly...

12 clocks / 8th (as MIDI asks)

>Or the same question rephrased, what is "too fast" in beats-per-minute?
>Jon

I dont want to charge the line more than 5%, which is about 1 clock / 6ms
-> minimum 6*12 = 72ms/8th
At 8 8th/beat, you get 96 clocks/beat -> minimum cycle time of 72*96 = 
691ms

I understand a beat as a quarter note, so we get 144ms/beat
-> 1000/144 = 6,93 beats/sec = 416 BPM
Is that too much for the repeater?

The new internal Tempo generator offers up to 26...280 BPM.
