Hi! I'm studying Farnell's book, and I've come across his sophisticated timebase with swing (pp.227-228), but i can't really seem to understand it... If I'm correct, it computes the value of a pulse, for example a quarter note bpm conversion to ms. He then divides it by what he calls "the beats" (as I see it, he more likely refers to the subdivision of the pulse, is that right? because if it isn't that, i don't get it!). And then he provides the option to apply swing to the beat, which I can't seem to make it work at all, the delay doesn't output bangs for me, which is pretty weird. This makes me think I don't really understand the concept of timebase... Am I missing something? Can someone explain briefly this patch to me? I'll leave here the abstraction and the patch where he uses it. Thanks in advance.

Here is the text that accompanies the example:

...(the example) allows you to specify the tempo as beats per minute (BPM) and to add a “swing” to the beat. Notice first that start and stop control via the first inlet also resets the counter when the timebase is stopped. Bangs from [metro] are duplicated with a [delay] object so we can position every other beat relative to the main rhythm. To convert beats per minute to a period in milliseconds it is divided by 60000 and multiplied by the number of beats per bar. The last parameter provides swing as a percentage, which is added to the delay prior to incrementing the counter.

@ChicoVaca Only a little time to play with this..... and really not my subject.
The [del] in [timebase] always receives a value that is greater than the [metro] interval, so the delay is always cancelled by the next bang coming from the [metro].
I changed the [+ 1] after the [/ 100] from the swing control to [+ 0] and maybe that solves the problem.
At least the control has some effect although whether it is the desired effect I don't know,
I slowed the [metro] so as to see what is happening....... sequencer.zip
I am sure that someone else will have a better understanding, but maybe this will help you to fix it yourself.....

@whale-av thanks for your anser David, it was really helpful, I wasn't taking into account that [metro] behaviour... I hope someone else will clarify the purpose of the rest of the patch! Thanks again
