2 years ago Hi not so kind Peter :) I dl your projects and it confirms my previous post. If you stop/start "in time" you may not notice the effect of bpm estimation but yes if I stop/start just after the beat then the bpm calculation can lead to an acceleration before the next clock tick. Since I never start/stop Zou during my "performances" I did not spend enough time on that issue. In terms of impact I think I can maintain speeds on tracks, I can even keep micro timing but the sole difference is that I will be constrained by the number of clock ticks in terms of resolution. If I consider that a step is 32 clock ticks max resolution will be 1/32th of a step (for step length, ratchets distance, micro timing, glide). That being said it might be enough for most users. Maybe we may add Omri Cohen to that discussion since he is a contributor on Zou as you are and make a kind of brainstorming :) I thought that another approach would be to remove the ext clock capability and let Zou manage its own clock and only allowing external resets. Now it is to you to let me know what you think.

Hi Seb, I still have problems with Zou Mai and restart/reset. the first few beats are not consistent at all, I think the reason for this is given by you :
Lets say zou sees 1000 ticks between each clock pulses. So with your configuration zou goes backward 2 steps each 1000 ticks i.e. a step is 500 ticks long. If you reset after 200 ticks consumption and you send a clock at the same time so the new base will be 200 ticks then zou goes backward 5 times faster before the next clock pulse occurs. If I ignore the clock signal when reset is fired the new base will be, with the same example, 1800 ticks long so zou would go slower before the next clock pulse. I do not know how to handle that kind of situation.Originally posted by @sebastien-bouffier in https://github.com/sebastien-bouffier/Bidoo/issues/152#issuecomment-623398575
What if there was an option the just let Zou Mai use the triggers/gates from an outside clock, without it trying to get the BPM. I know you can not use the 1x2x3x4x speed any more because it does not know the speed/bpm. Or maybe do it the way Voxglitch does it with his Groove box :
https://github.com/clone45/voxglitch/blob/master/docs/groovebox.md
He uses a x32 clock input and it's as steady as a rock/clock ;)
Let me know what you think,
Greetings Peter.
Below is an example that manifests the Zou Mai problem, use the spacebar to stop/start the sequence.

And here is one including the groove box it also ratchets ;)
