Envelope Follower Automation Bug / Workflow Issue

This is just a workflow warning on using the envelope follower. If you intend to do any automation eg track /pad mute do it BEFORE you add an envelope follower to the track otherwise the automation will continuously write the modulating envelope, as in my case I had the LFO modulating the cutoff / resonance on a filter insert on an audio track. I was then doing some pad / track mute automation. This then causes the MPC to issue a Disk Error message as it can’t keep up with the sequence you are playing even though I only had a drum track, a plug-in and two audio tracks. Then going back to the track on arranger and calling up the LFO envelope automation lane to delete it will cause the MPC to crash.
