Hello everybody,
I would like to create a metronome that provides a beat time with phase, like the one provided by abl_link~ object, but in realm of messages.
The decimal values of the phase will be used by my sequencers to derive the rhythmic subdivisions (1/8, 1/16, 1/32, etc...), and in this way they can follow the realtime changes of the bpm.
I made a patch that use [metro], [cup] and [line], and it's working, but I noticed that at some bpm I don't have stable subdivisions, perceived by ear and also verified with a simple tap tempo.
Comparing my implementation to another one that uses [line ~], I noticed that the one with [line ~] is more precise, probably because [line~] provides more decimals than [line], and perhaps this is what causes the subdivisions based on [line] to be less precise.
What do you think? Do you have any advice on how I could implement it to have stable subdivisions?
I would like to avoid solutions in the "audio realm" like [line ~], because they would create other problems of sync with other pieces of my project, which works exclusively with messages.

Here is the patch I made (both [line] and [line~] included):
metro_phase.pd

@bamboomusic You can increase the accuracy of [line] setting a "grain" .... a time between outputs.... as a second argument.
So [line 0 1] will start at 0 on creation and will output every millisecond as it ramps.
[line 0 0.1] will output every tenth of a millisecond.
The default is 20msecs if you don't give it the argument...... which is probably why your beats are inaccurate...... as you guessed.
David.

Thank you David,
tweaking the grain setting was just what I needed!
With a value of 8ms the accuracy became reasonable, without putting too much pressure on the cpu.

Greetings
