@Future - just a suggestion - IMO it’s very useful if you give the link some descriptive text, (for example, many folks recommend writing links like ‘see [how to xyz]’ instead of using something like ‘for how to xyz, [click here]’). This gives much more immediate context about what the link points to Even better in this case though, you can allow discourse to show a preview of the page that you are linking to, if you place the link on its own line
Hmm, here’s a template solution, which I’ll try to explain:
use_bpm 120
##| initialise time state variable :run
set :run, true
live_loop :kick do
##| alternate between loud and soft
sample :drum_bass_soft, amp: [0.8, 0.4].ring.tick
sleep 1
stop unless get :run
end
in_thread do
##| offset by 1 beat
sleep 1
live_loop :snare do
sample :drum_snare_soft, amp: 0.8
sleep 2
stop unless get :run
end
end
with_synth :tri do
live_loop :arp do
##| cycle through arpeggio ring
play [:a3, :c4, :e4].ring.tick, amp: 0.6, sustain: 0, release: 1/8.to_f
sleep 1/4.to_f
stop unless get :run
end
end
live_loop :clock do
##| advance tick up to limit
if tick == 6
set :run, false
stop
end
sleep 1
end
Basically, you want to keep a separate clock loop the moment you have more than one loop you want to synchronise to stop.
Notice how each live_loop keeps its own tick, whereas the time state variable :run is shared everywhere.
In this template, you can also see how a snare (or clap) can be offset by a beat using an in_thread on its inception.
I’ve set the clap to tick twice for experimenting sake, but it is not turning itself off after 2, it was doing it after 11.
Also, my drums all come in different times, but I want them all to cut out at the same time. will this clock thing allow that?

The 2 intermediate calls to sleep 8 that you’ve placed in the main thread block the onset of the clock loop for a total of 16 beats. That’s why it claps 11 times: the countdown hasn’t begun. To fix this, I would put the calls to sleep inside each thread individually. That way, they don’t block the clock.
E.g.
in_thread do
sleep 8
loop do
sample wn_u_fx .ring.tick
sleep 32
stop unless get :run
end
end
While it may not affect what you hear, the irregular sleep times in your loops (e.g. sleep 16 and sleep 32) mean that the loops detect the change of :run at different times. To fix this, I would sleep at the same interval of 1 beat in every loop. I would use the modulus operator to determine when to play.
E.g.
in_thread do
sleep 8
loop do
sample wn_u_fx if (tick % 32).zero?
sleep 1
stop unless get :run
end
end
Because the onset of your latest loop is delayed by up to 16 beats, your clock should run for at least 16 beats. Any shorter, and you’ll have stuff playing when it shouldn’t.
If you follow 1 and 2, then the drums should cut out at the same time.
I got your first point done, but I don’t understand your second point about the modulus operator. can you pls try to explain a bit more simpler? thanks for your patience
Certainly! I’ll illustrate what I mean with my DAW.
Currently, you have code for several “tracks” that end at different times:
The reason these tracks end at different times is that their sleep times are different. As a result, the tracks don’t check for the end of the piece until their sleep is over.
What we want is for all our tracks to end at the same time:
In order to do this, every track needs to check for the end of the piece at the same time. That’s why I replaced your different sleep times (e.g. 8, 16, 32) with the same sleep time: 1. But because each loop is only sleeping for 1 beat now, everything is playing on every beat! So to get the instruments to play once every 8, 16, or 32 beats, I add a condition to their play statements depending on how frequently they’re supposed to play. E.g. if (tick % 32).zero? plays every 32 beats, meanwhile if (tick % 16).zero? plays every 16 beats.
I hope this clears things up a bit? Please feel free to ask for more clarification. I don’t know if I’ve done a good job simplifying.
