Problem with V: Launchpad, RAM and freezing

PostMon Jan 13, 2020 11:08 am

My upgrade to Hauptwerk V on Windows 10 went smoothly and without event.

While playing---sometimes for up ten minutes and sometimes for up to an hour with everything functioning normally---my Launchpad MkII (which is plugged in to a MB USB port directly and not via a hub) will enter a LED RGB lightshow mode where none of its buttons responds to user inputs. Hauptwerk will freeze when I attempt to unload the present organ or modify settings (such as to modify MIDI OUT and IN settings), and will sometimes freeze when attempting to generate a diagnostic file. My polyphony setting is at 2016 and is not close to being overloaded at the time of the interruptions; sometimes they occur without any MIDI inputs or outputs. Attempting to force Hauptwerk to close from within Task Manger does not cause the task to end, and Hauptwerk retains its hold of the RAM that it had been using prior to the freeze. A system restart is required to reset it.

If I do not restart I can open a new instance of Hauptwerk despite the first instance maintaining its hold of the RAM. Sometimes this new instance prompts me with the "Device not connected, are you sure you want to launch Hauptwerk? Proceed, mark device as temporarily offline, etc" window. Other times it will launch without showing this screen but will display the following error message instead:
"Could not open MIDI OUT port: 'Launchpad MK2'. Make sure that the port is not in use by another program. (Operating system message: There is not enough memory available for this task. Quit one or more applications to increase available memory, and then try again. Message for diagnostics: 3818".
Task Manager reports that there is about 10GB of free RAM available.

I have attempted to connect the Launchpad to USB3 and USB2 ports on the motherboard and have swapped its place with the connection for my audio interface (prior to powering the system on) with no change in the sporadic nature of the fault. The computer is not connected to the internet and is running an iLok Gen3 dongle. Sometimes I can play for extended periods of up to five hours with totally normal operation and the problem crops up irrespective of the organ I have loaded, including making an appearance while using St Anne's. One instance caused the display to present a mostly black screen with artefacts, and after one recent Launchpad lightshow but before the program froze I managed to create a diagnostic file which I am happy to send on.

I am grateful for any help you might be able to provide and I thank you in advance.

Hello clausula_tenorizans,

In case your computer is experiencing memory issues with Hauptwerk v5 (which seem to affect a few Windows 10 PCs), I'll send you a forum P.M. with a temporary work-around that should avoid that.

Please let us know whether that resolves it. Thanks.
Best regards, Martin.
