Hanging Dwarf

Dwarf froze, purple light on centre pedal, totally unresponsive, after between one hour and four one hour and eight minutes using this pedalboard Shaggy parallel bass with full control - MOD Devices

The sound was still coming through both channels, one clean and one with plugins. The GUI was still showing, but although I could delete items from it any changes made on the GUI were not made to the Dwarf. Solved with a reboot. Unfortunately I don’t remember exactly which plugins were active at the time, but I’ll listen to the recording (yes, I was in a session!) and see if I can identify what was being used. I was connected to the GUI using a Bluetooth dongle in the back of the Dwarf.

EDIT: Having listened to the recording I can say that the DS-1 distortion and the DxDigital Delay were both turned on. The signal path was passing through all four effect plugins, but the wah and the SubSynth were turned off. The path was not going from the subsyth to the delay, but straight to the mono dynamics, which as also turned on, and operating as a hard limiter at -12db.

How to reproduce

Nothing specific, I was not changing anything, it was the end of a song, I went to change settings and saw that the Dwarf was locked up.

Expected/suggested solution

Not to happen again! I don’t know if this was due to the Dwarf itself or one of the plugins, so the solution could be any number of things.

Hey Simon,
really sorry for the late reply. Your report was open on my browser for a while and I wanted to give you an answer, but time was not really on my side to understand your issue.

Thanks for reporting this. We were trying to figure it out, but unfortunately, it is very hard to figure out what went wrong exactly in your case.
Are you somehow able to find a somehow reliable way for us to trigger the problem? That would really help us out finding and fixing the bug.

On another note, update 1.11 (which we aim to have a release candidate for in the next weeks) has bug fixes for some issues causing controller lockups. These could potentially be related, but it is hard to say for sure.

Hi Jon, no worries on the time, I know you guys are busy! I’ll try to reproduce and see if I can find a direct cause and let you know.

I had a similar issue yesterday. Sound still going through fine, but interface completely frozen. I hadn’t been playing for that long, it was just a few minutes after turning it on. If there’s anything I can do to help debug let me know.

Also on the Dwarf? Which OS version are you running there?

Hi Jon, I’ve just had another hang, this time using this pedal board Shaggy 4 bass out Version 2 - MOD Devices. The only active pedals were compression and wah. The amp sim and speaker sim were selected and on.

I set the board and selected the snapshot on the GUI using a bluetooth link and then closed the GUI and went to the Dwarf and hit the centre and right pedal to take it into selection mode. I then pressed the left pedal to go into snapshots and the Dwarf hung. CPU was around 60% and Ram around 40%. The Dwarf was still making the right noises, but I couldn’t do anything on it. Had to reboot to get it back to normal. It had been powered on for a good couple of hours, but that was the first time I had closed the GUI.

Hi Simon,
Thanks for the report. We will try to reproduce it and check what is happening.

EDIT: I got an answer and, there are some bugs on navigation mode currently. Those bugs should all be fixed with the 1.11, so it’s a matter of time for it to get solved.

Thanks Jon, that makes sense - I was using yesterday and it hung another couple of times, both when I was moving between snapshots. I’ll wait for 1.11 - any rough ideas as to when it might make an appearance? I saw mention of RC versions elsewhere, so I’ll try those, if I can, when they are released.

We are doing what is supposed to be final testing this week.
Target date is early October for now, unless we find some last minute show-stoppers.
