How do I ensure that a cycle starts from the beginning every time I start it?  
I know I saw this in some video but I can't remember where.

Thanks.

You can use `resetCycles` but I think there are some quirks about it:

```haskell
do
  resetCycles
  d1 $ s "bd"

```

Some more information about how to handle resetting the cycle count is available in the documentation for `seqP`: [https://tidalcycles.org/index.php/seqP](https://tidalcycles.org/index.php/seqP)

Thanks. resetCycles seems to be doing the trick as far as I can tell.  
I'm curious to hear more about the quirks. Are there things that might stop me from wanting to use it?

Cheers.

I haven't used it in a while, but as I recall sometimes it would "hiccup" and not start smoothly. It can get off to a weird start sometimes. But, not all the time. 🤷‍♂️ Your mileage may vary depending on what you are doing!

Okay thanks. I'll see how it goes.

There's also reset:

You can specify exactly a twelfth of a cycle in the mini-notation with "1%12" So that could be "0 1%12 2%12" etc. Alternatively you can specify it as "0 .. 11"/12, or using the run function, run 12/12. To superimpose a copy of a pattern on top of itself with a pattern applied, you can use superimpose, e.g. d1 $ superimpose (twelfthPat \<~) $ sound clapPat. I like jux, which is similar but pans the original and the transformed patterns hard left and right respectively. resetCycles i…

Yes I was puzzling over the difference between `reset`, `trigger` and `qtrigger`.

```haskell
d1 $ trigger 1 $ sound "clap*4" # speed (rand + 1)

```

This quantises to the nearest cycle start (the 'sam')

```haskell
d1 $ qtrigger 1 $ sound "clap*4" # speed (rand + 1)

```

I'll have to have a proper look, but I'm not sure of the difference between `qtrigger` and `reset`  
The '1' refers to the 1 in 'd1' by the way

</div>

for anyone finding this thread looking for info on `reset` and `qtrigger` --

both shift pattern time 0 to the next cycle boundary, i think the difference is that `reset` also mutes the pattern until the cycle boundary so it starts sounding at pattern time 0. `qtrigger` doesn't, so you'll hear the pattern content at negative times, from when you execute `qtrigger` to the next cycle boundary. `trigger` meanwhile is not quantized so there is nothing to mute, it shifts pattern time 0 to _right now_.

so for example if you are composing and want to hear your piece from the beginning, you probably want `reset`. if you are performing a transition you might use `qtrigger` to include a lead-in/fill before the change. to start a _pattern_ immediately (out of sync with other patterns) you would use `trigger`. similar to how you can play a sample immediately with `once`.

`resetCycles` is currently inaccurate and may often lose an event at the start of the first cycle.

This will be fixed properly at some point but for now a good workaround is to manually adjust the definition of resetCycles so that events aren't missed:

```haskell
resetCycles = Tempo.changeTempo (sTempoMV tidal) (\t tempo -> tempo {Tempo.atTime = t + 0.1, Tempo.atCycle = 0})

```

You can increase that 0.1 to a value that works best for you, and put it in your BootTidal.hs to make it permanent.

Is there any way to trigger `resetCycles` via osc?

I'm working on a recording setup in Ardour where I start the recording and "start" tidal at the same time, meaning that all of the audio and midi recorded will be aligned to the grid.

```haskell
resetCycles = Tempo.changeTempo (sTempoMV tidal) (\t tempo -> tempo {Tempo.atTime = t + 0.1, Tempo.atCycle = 0})

```

Evaluating this statement gives me an error:

"Not in scope: ‘Tempo.atCycle’  
No module named ‘Tempo’ is imported."

I also tried adding it to the BootTidal.hs and wasn't able to boot Tidal. I'm not sure where I should be adding it.

Hi @palinopsic, resetCycles has been reimplemented in Tidal 1.9. I don't know if the mentioned bug can still happen. If it can, please open a bug report and I'll have a look.

The implementation of resetCycles is now [Tidal/BootTidal.hs at c529f7063f111dceaba4eb7db15da74b025d82f3 · tidalcycles/Tidal · GitHub](https://github.com/tidalcycles/Tidal/blob/c529f7063f111dceaba4eb7db15da74b025d82f3/BootTidal.hs#L29)

Hey @Zalastax, as far as I can tell, the first event is always skipped when using resetCycles.  
Resetting a pattern like "bd sd cp" will skip the bd event. Is this a bug?

Hi @palinopsic, yes that is a bug in my opinion. The relevant code is here: [Tidal/Tempo.hs at c529f7063f111dceaba4eb7db15da74b025d82f3 · tidalcycles/Tidal · GitHub](https://github.com/tidalcycles/Tidal/blob/c529f7063f111dceaba4eb7db15da74b025d82f3/src/Sound/Tidal/Tempo.hs#L215)

I can try to look into it but it would be best to get a bug report in Github so it's not forgotten about.
