Meta Morph : Early Access

thetechnobear · November 22, 2023, 4:13pm

Overview

Meta Morph is an open source project featuring vcv rack modules to use with your Eigenharp.

An introduction into Meta Morph, and its motivations and goals can be found
Meta Morph Introduction

Early Access

Meta Morph is being released into Early Access to give the community an opportunity to improve Meta Morph before release.

it will focus on:

testing
development of demo/tutorial patches
development of user documentation
development of preset patches

by definition there’s limited documentation etc and may be bugs, or known issues, so its not for everyone
the aim is to ensure that when released new users will have a good experience, by sorting this out with a dedicated group of users.
the other aim is to (hopefully) reduce efforts in these areas on my part, and so allow me to focus on development.

I should also stress whilst changes and new features may be added during EA, this is NOT its primary goal. It’s focus is to get what we already have ready for general release.

How EA users can contribute?

testing

In this role, if you gave issues you will need to provide a simple patch that illustrates the issue.
the simpler the better… I dont have time to go thru massive patches that are not working, you’ll need to ‘isolate’ the problem.
we will need to est

develop demo/tutorial patches

we will want to co-ordinate this so we cover a broad base.
Im not after very complicated patches, rather patches that will show new users how to use modules.
There simplicity also will help with the testing aspect (see above)

improve user documentation

my documentation will be a bit sparse initialy, it would be useful for new users to read these, and start expanding on them.
new users are ideal for this, as they are a blank canvas, so know what needs to be documented.

development of preset patches

This will be in the LATER part of the EA program, when the modules are considered mature (unlikely to change).
Here we want a couple of more complex patches for each Eigenharp, that new users can use as a ‘starting point’
unlike the tutorial patches, these to do aim to teach, so complexity is not a problem.
e.g. the Factory presets for EigenD are useful to all EigenD users, but they are not easy to understand/modify.

Important notes on patches

This must only use VCV Factory Modules (and Meta Morph) so that any user can install VCV and use without installing any other modules.
this is very important support and and first impressions.
we will also have a means to share more advanced patches before users… but they are not considered part of the EA program.

The final important aspect of being part of EA is by helping contribute the above, you will gain knowledge in Meta Morph, its goals and how it works.
this will enable you to participate meaningfully in dicussions about how things can evolve.

None of the above needs to be particuarly time-consuming, nor does it require any special expertise.
But I am asking for a bit more commitment, that I’ll install it, and fiddle with it for a while … needs to be a bit more focued!

What Early Access is NOT

It is not a general release for those that want to use Meta Morph but will not ‘contribute’ to the project. As you can imagine I’m very busy with development, so at this stage I want to limit my ‘support’ to those that will help the project. once the EA is complete, then due to EA goals, it will be easier to support, so I can help more users.

How to gain access to Early Access?

Please read the “How EA users can contribute” above, and decide if you will be willing to contribue.
if so, then send me a DM, @thetechnobear

note: Initial release will be macOs only (arm and intel)

Bugs / Issues

please report bugs or issues here, so that other community members can verify issues.also please state, if you are running on Intel or Arm.

Finally please make sure you are running the latest version of VCV Rack, as I will only be testing / developing with this (currently I believe it’s 2.41.)

reserved for future use…

thetechnobear · November 23, 2023, 3:19pm

could those with EA please test each of the demo patches that they have eigenharps for and let me know if you have any issues.

also please state if you have test on Intel or Arm (M1/M2)

GoneCaving · November 23, 2023, 3:31pm

OK, so working on a 2018 x64 MacBook Pro, I’ve spotted two issues so far testing with my Alpha, using the Free version of VCV Rack v2.4.1

Creating a simply patch along the lines of the the intro video, I note that the percussion keys are sounding when only the main keygroup row is connected from the Eigenharp module.
If I start with a blank rack, load the Alpha.vcv that comes with MetaMorph, it loads ok, but as soon as I set the Audio Out, VCV crashes. I’ve sent the crash report on by email as it’s a little too long to include here. I’ve also tried to delete the Audio module before setting the output device it also crashes. Trying similar with the Pico and it’s also crashing. Creating a simple patch from scratch for the Pico also works ok as with the Alpha. Reloading my simple patches works ok. The crash reports suggest the issue might lie in the Function12 module.

OK, I can confirm that I can crash Rack in a clean slate just by loading the Function12. All other modules load ok. When I load the Alpha sample, Function12 loads, and I can interact with it. If I delete it, then I can set the Audio device, but then crashes when I try to add Function12 again.

thetechnobear · November 23, 2023, 4:49pm

Alpha - oops, yup found the issue…
Ive got some inconsistency in EigenLite between Tau and Alpha which I need to resolve. I just need to decide which is correct

Function12 crash was caused by compiler differences for Intel and Arm -Ive fixed this one.
however, we will need to keep an eye out for other issues. since Ive done all my testing on Arm.
fortunately, I was able to reproduce issue by running Intel version of Rack2 under Rosetta… but then was a bit of trial and error to find out what one compiler was fine with, and the other not!

tl;dr; once Ive resolved and testing alpha issue, I’ll out out a new build. and let you know here.

NothanUmber · November 23, 2023, 10:45pm

Some first tests with Pico on a 2023 M2 MacBook in both native and x86 (Rosetta) mode (with macOS 13.6.2).
In case it matters (e.g. for the led topics): The Pico is connected via a small passive usb-c to 4xusb-a hub.

In x86 mode (this will be my main music platform later on, just testing on my work notebook for now):

lights cannot be switched off anymore, I can only change the color (with both scaler or illuminator) - works in ARM mode.
when quitting VCV the leds flash (not happening in ARM mode)
Function12 crash as already reported above (not happening in ARM mode)

Some observations (not bugs):

first tried to utilize the single opportunity of complete cluelessness - to try out the modules without watching the explanation video or reading any documentation. The major thing I didn’t guess right was the meaning of the rows in the Eigenharp module (first row function keys, second row main keys, third row bass keys). Perhaps some labels might help? And that some buttons that cannot be turned actually have a right click menu. (Could turning the knob still switch through the options? Or perhaps another UI element than a knob might be easier to understand?)
Scaler applies scale to both rows and cols. That was a little unexpected but can also be cool (e.g. pentatonic in both directions and then playing random notes ). But perhaps we could choose scales for rows and cols separately, so one can e.g. have pentatonic rows and still a major third (which isn’t part of the pentatonic scale) between cols?
On EigenD I think there is a function applied to pitch bending on the x-axis(?) (Edit: Ok, it’s also exponential and not linear in Meta Morph!) And I often only used a quarter tone pitch bend range instead of a semitone. These things can be changed with separate rescaling modules though, so I think I will get this behavior back if I want to.
Perhaps additional relative (resetting) Strip outputs would be nice? But connecting the absolute, decimated Strip to Global pitch bend in actually cool on Pico, so one can quickly dial in octaves

GoneCaving · November 23, 2023, 11:28pm

Yep, it also might be nice to have a gate on the strip outputs. I was thinking about a way to have a filtered noise generated from the strip, but the Q is then how to control the VCA.

thetechnobear · November 24, 2023, 8:58am

not sure I understand this, will test on intel

yeah, I need to add labels… but space is a bit tight in the UI

I thought it did… but this is a limitation of the default controls I believe
and some point id likely switch to some custom controls, but its not a priority - I want to get functionality in place first.

this is deliberate, it allows for a very flexible scale layout across the surface whilst being extremely quick n’ east - but you do need to ‘think it thru’ and get your head around it. also remember, by creating your own Scala file you also control layout as well as scales… think creative , abuse it

also back to UI complexity/layout… its going to be better to create alternative modules rather than creating more complexity in one module, thats the modular approach.

im not quite sure how you think you’d do scales separately for rows/cols given then are the same thing… but it’d be a separate module, and separate discussion.
BUT this is advantage of modular, separating concerns KISS, and even allows other devs to come up with variations (hence ‘dev api’)

quarter tone pitch… you can use an attenuator to reduce range of input rather than PBR. again UI limitation, I think it’d kind of be a pain for it not be semi tone snapped.

@NothanUmber @GoneCaving strips
yes, I considered both (gate and relative) the issue is UI space…
adding both relative and gate = 4 more outputs (as we have 2 strips)

that said, relative is probably not required if you have gate, since relative is just a function of absolute… youd just need to use a differentiator.

I’d also wondered if a bipolar output might be better, with 0v in the centre…it feels a bit more natural to me. (and you can use a scale/offset get back to unipolar)

more generally, Im considering going back to a principle of 10v pp output. , as I find the range a bit ‘wide’ currently.

X,Y,Strip, Breath = -5 to 5v
Z = 0 to 10v

(it was like this before my latest eigenlite changes, but I switch as I thought standard 10v was more intuitive, but now Im not convinced)

overall, you can see UI limitations comes up frequently.

generally, the modules are pretty big already ,due to number amount of IO (from harps) , and I don’t want to increase the sizes, and I dont like ‘fussy’ UIs they need to be ‘clean’
similarly Im using standard UI component at the moment to focus on functionality.

once things are more mature Id like to work on the UI a bit, custom controls etc … and perhaps with someone that has a flair for UI can help improve the UI, make them tidy.

so Im working within a few constraints for now.

thetechnobear · November 24, 2023, 10:19pm

release 2.1.1

quite a few changes in this…

fixes:

various issues with Alpha
various issues with intel build
rationalise use of courses in EigenLite

changes:

x, y, strip 1-2 are now bipolar -5v to 5v, z remain unipolar 10v
(basically standardised on 10v pp)
strips return to zero on release.
labels added to eigenharp modules key groups
scaler - offset renamed to Ref to better describe its purpose and use.
leds are now cleared when processing is stopped
update demo patches to use slew on Z to remove ‘clicks’
improve pico strip handling (less quantisation)

NothanUmber · November 26, 2023, 3:38pm

Tried it on my music Mac (MacBookPro11,3; x86; 16 GB RAM; macOS 11.7.10 Big Sur) today, getting an instant segfault in VCV Rack (Pro 2.4.1) when right clicking to list the modules. (VCV Rack doesn’t crash as long as Meta Morph isn’t installed).
Apple doesn’t support newer macOS versions on this machine. (There is OpenCore Legacy Patcher, but I am hesitant to use this as long as all applications still work) Here the content of the log file:

its dying whilst in vcv code, appears to be when adding a ‘standard’ input port widget.
absolutely no idea why… the trace gives no indication as to possible fault.

given I don’t have anything with with 11.7.x on, on anything anywhere near this age … theres no way I can test nor debug this.

Im assuming this doesn’t happen on other intel (more modern OS) versions?

NothanUmber · November 26, 2023, 4:10pm

Here the details that would go into the Apple report. Don’t see anything Meta Morph specific…
Have also unplugged the hub with all usb devices as a test. Didn’t help.

yeah, Ive just been looking at code… both my code, and also the relevant VCV Rack code in ModuleWidget (etc)

so my call into the api is here

2 libRack.dylib 0x0000000101945166 rack::app::ModuleWidget::addInput(rack::app::PortWidget*) + 38
3 plugin.dylib 0x0000000101505e35 EDeviceWidget::EDeviceWidget(EDevice*) + 1285

which is…

addInput(createInputCentered<PJ301MPort>(mm2px(Vec(63.211, 77.953)), module, EDevice::IN_FUNC_LIGHTS_INPUT));

with the exception of the enum (which is correct) , thats all vcv code.

this line of code is actually auto generated by a helper script, and everything around it is correct.
why just this module , no idea… possibly something to do with the svg file its just loaded causing memory corruption?

but any which way, from what little we have , it looks like its a bug in vcv rather than my code.

only other thing I can think of, is something in the build tools setup, thats causing an issue for earlier versions of macOS, but again without a testing/dev environment… thats just a stab in the dark.
nothing really I can follow thru on.

NothanUmber · November 26, 2023, 4:27pm

@GoneCaving which macOS are you using on your Intel Mac? When looking at the OpenCore Legacy Patcher issues list it seems to get longer the newer the to-be-installed OS is. So if nothing helps I would consider to jump to a newer (unsupported) macOS - but for mentioned reasons preferably the oldest that is known to work with Meta Morph.

thetechnobear · November 26, 2023, 5:07pm

actually Antonio is the master in this area :). @keymanpal

he tested a very early build of this on intel for me.
specially, High Sierra (10.13) and Mojave (10.14) , and didn’t appear to have any issues.

@keymanpal could you possibly try 2.1.1 on some early intel machines?

actually also 2.1.0 too… to check there is not something recent causing the issue.

(at this point, its just enough to check that you can do browse modules with them installed)

NothanUmber · November 26, 2023, 5:51pm

Playing around on the M2 Mac. The scaler Global input seems to retune a wholetone when setting the knob to 1 with scale “default”. This is a little unexpected because for the keys “default” is chromatic.

thetechnobear · November 26, 2023, 5:55pm

5v = PBR range for global and note… (it previously was 10v changed in 2.1.1)
neither of these inputs are based on scale…
(both note and global should behave the same, unless I missed something on latest change)

actually, I wonder if I should ditch the pbr range , and just make them v/oct.

NothanUmber · November 26, 2023, 8:52pm

Sounds plausible. +/-10 octaves sounds sufficient for most kinds of music and species

thetechnobear · November 27, 2023, 12:20am

ok, for those following this topic, and the issue on Mac OS 11.7

the issue @NothanUmber was having relates to building on macOS 14.x, and the related compiler/sdk it uses.

we tried with a build Im doing via GitHub which is using macOS 12, and all is ok, so I’ll use GitHub to do future builds.

Ive updated the previous release for this, use previous link to re-download.
(good to do even if it does not affect you, just so we are all on the same version!)

it be useful to track what versions people are testing on… just in case we see other oddities like this.

thetechnobear · November 27, 2023, 12:22am

yeah, Ive not quite sure though… as it means to get the bends you want, you’d need to scale the inputs, which is kind of tedious.
