Hi everyone,

we try to clock our shows as good as we can to the tempo of the music being played.
We noticed some faulty behavior with the Master BPM fader in any deck.
We create all our FX at 120 BPM and then use the fader in a deck to adjust the FX speed to the tempo of the tracks being played.
We noticed the following increments (both with mouse as well as keyboard):
120
121
122
124 (note the missing 123)
125
126
127
128
130 (note the missing 129)
131
132
133
134
136 (note the missing 135)

Can someone please look at the missing BPM intervals?
We assume some rounding error internally somewhere.

Thank you very much in advance

Hello Lefaux,

Frankly this is not an error.

The missing steps stem from the rounding of the values due to the default value of 120 BPM.
The speed is basically a percentage value.

Please see the following calculation:
1.02 * 120 BPM = 122,4 (this value is settable)
1.03 * 120 BPM = 123,6 (value is rounded to 124, thus 123 is missing)
1.04 * 120 BPM = 124,8 (value is rounded to 125, value is settable)
...

If you need a "finer" granularity, you will need to adjust the default BPM (e.g. to value "100").

This allows you to use single steps:
1.02 * 100 BPM = 102.0
1.03 * 100 BPM = 103.0
1.04 * 100 BPM = 104.0
...
