Troubleshoot 'undo'

[jomtones]

I have a step sequencer I'm using live with my drummer but it's generating unwanted 'undo' history - I'm not sure why or which part of the device is generating it. Is there any way to troubleshoot the device to track down the culprit?

Thanks

I had that too - a device I made was totally overloading the undo buffer. Turned out it was parameters I was continually modulating within the device via other Max objects - I had 16 [live.gain] faders rapidly ramping up and down via [line] objects. The faders constantly shifting positions were sending the undo buffer crazy. In the end I hid them from Live so they can't be automated but I got my Undo back.

Could you set your sequencer going then look at the Undo option in the menu and see what parameter it says (eg, 'undo change in "deviceName") to get some idea of what the culprit is?

Thanks - so many devices in there I'm not sure what it's talking about even when I read the 'Undo' ... I was hoping the Max troubleshooting tools might be able to help? I've never figured them out!
