Support for RPi4

[lee-yunseok]

Waveform 11 Pro trial user here with RPi4 4GB 64bit kernel Raspberry Pi OS(Raspbian). With over 1 month, Waveform is only one premium DAW for RPi in my impression. To continue using the Waveform, I leave a request and question below.

First I request some improvements:

1. No icon in task bar. Please add it.

2. On browse files, can't see directory structure. I can see it only when using Grayscale (Light) scheme. Also arrow and Up text overlap in the button.

Second I wonder:

1. Multi Sampler too slow than LMMS or MusE, and Fluid when load sf2 over 300MB, also Waveform crashes when load 1GB. Is there a way to solve this?
2. Some racks can't found plugin like TAP series. Is this because it is a trial version?
3. Auto-Tune and Melodyne, Elastique in basic, and other standard or extreme contents support RPi?

1. I thought I'd fixed #1. Are you on latest version? Otherwise, I'll need to do another build. I should do it anyway, the Pi version is a bit behind.

2. We really need to fix that for all Linux. I'll put it on the todo list.

1. Multi Sampler only plays samples from ram. Pi is 32 bit OS. If memory runs out, it'll crash. Unlikely we will add a disk streaming mode.

2. All the racks should be there.

3. It is unlikely 3rd party software like Auto-Tune or Melodyne will ever be available. BioTek requires too much cpu. I need to do lastest version of Collective for Pi.

Hello @FigBug,

First requests:
1. I think I'm using recent package but as you said Pi version is a bit behind so it doesn't seem to be resolved in the Pi build.
2. Thanks!

Second questions:
1. Thank you for the answer. I'll consider recent 8GB or future 16GB Pi.
3. Thanks. Actually I don't need Auto-Tune or Melodyne, also I have no experience with Elastique and I don't think it is what I need. I am very happy to hear about the latest Collective.

1. Multi Sampler only plays samples from ram.

This is an understandable limitation.

If memory runs out, it'll crash.

This should be treated as a bug and fixed. Nothing should be allowed to crash unless there is an actual hardware failure.

This should be treated as a bug and fixed. Nothing should be allowed to crash unless there is an actual hardware failure.

Unfortunately the way Linux works, when you request memory from the OS, it always says some is avaliable. Then when you try and use it, if the OS can't actually provide it, it kills your process.

By default, Linux follows an optimistic memory allocation strategy. This means that when malloc() returns non-NULL there is no guarantee that the memory really is available. In case it turns out that the system is out of memory, one or more processes will be killed by the OOM killer. For more information, see the description of /proc/sys/vm/overcommit_memory and /proc/sys/vm/oom_adj in proc(5), and the kernel source file Documentation/vm/overcommit-accounting.

Ugh... who came up with that one?

I can see it needing to do stuff like that when using copy-on-write with a fork operation, but for a malloc?

Understood that it leaves you in a rough position, but that is flat out a bad design.

On recent 8GB RAM RPi4, Waveform no longer crashes when I trying to load sf2 over 1GB with Multi Sampler. But it can't load sf2 over 400MB. The loading bar always stops at zero.

Added: I decided to load large soundfonts using Carla.

.39 still having the issue.

2. All the racks should be there.

I'm sorry I was mistaken it for TAPs. Also I found Daw Essentials trial. Sorry for confusing.

Other feedback(Edited):

1. Pi users seem to need the offline unlock. All unlock buttons doesn't work.
2. When I save the project or close the unsaved project without save, it hangs for a minutes. Is possible to improve this?

Solved.

When click the download Waveform 11.1 for Pi in Waveform and Tracktion website, it links to download Daw Essentials.

It has been solved from mail support.
