Sadly, I cannot use GP4.
Main issue is it completely locking up, which is most repeatable by going into the tuner. I can manually (mouse) enter, tune, exit the tuner but if i use a MIDI message (will be my use case for stage use) - it’s gone. I have to kill the task. Every time.
There have been a few times also where it has gone unresponsive simply on gig file load at initialization. Not repeatable, but I cannot trust GP4 for live use.
Are there any command-line options i can use to help dump debug info?
You have to take care that some pugins could check Internet connections because of Usage data sending etc.
In GP4 when you load a gig you get a window showing which plugin is loaded.
Can you see here any possible issues?
OK with Ableton Live sending a multiple CC message I get a flicking tuner too.
When I only send for example CC 27 and the value 127 the tuner is opened and sending CC 27 value 0 the tuner is closed.
What Midi Message do you see in the global MIDI monitor window.
Maybe we detect some issues when the CC messages 0 and 127 are sent in a too short time distance.
There seems to be a bug where switching to a different rackspace while the tuner is running could produce this problem. We’ll definitely work on this and address it ASAP.
In the mean time - please press the tuner button again to exit the tuner mode before switching to a different rackspace.
