M4L Mono Sequencer – crash

December 16, 2013 | 2:24 pm


M4L Mono Sequencer causes serious crashes in Live 9 !
Seems to be linked to the "pattern change".
I also experienced some audio drops due to CPU peaks when changing sequence pattern.

Bad news… I found this tool really great…

Any idea ??

It seems that Live crashes when I change pattern with quantize option enabled ;;;

Hi Fred-B,

Could you drop me a mail about this? kleine [at] ableton [dot] com

My quick hack to get around this was to automate the device to go off and then on with an automation envelope, a very small 64th note just at the end of the bar.

Thanks for the trick ! Always good to take ;;;

I’ve been in contact with the Ableton team since dec 2013.
The bug has been reproduced and confirmed.
Since then I’m still waiting for a solution … (can you hear me ?:)

It’s a pity because Mono Sequencer is really a great tool !

I must admit that M4L is far from being the more stable environment ;;;

Hope I can play again with the Mono Sequencer !

This problem has been addressed and the fix will be in Max 6.1.7

Great news !

The crash issue with the mono sequencer seems to be solved. Thank you !!
There’s still something wrong with the use of "quantize" for changing patterns.
It causes a small interruption in audio.
Still not usable with "quantize" on ;;; Arrghhh…
Would it be possible to have this feature ?

thank you

I too have the audio dropout / glitch when changing patterns with quantize enabled. Please, please fix this!

Same here. Live 9.1.2 Max 6.1.8 MBP dec 2012 2 x 2.4 ghz…

I’m still waiting for a fix for this bug … …

I’m not using it anymore …

Do you guys have confirmation from anyone that the bug has been logged? I just tried to repro and I couldn’t. If someone would like to send me a small live set with some instructions on how to reproduce this problem that would be awesome.

Please include as much detail as you can. If the live set is made with stock MFL devices, all the better.

Please send it to
