drmr's Introduction

DrMr

DrMr is an LV2 sampler plugin. It's main reason to exist is to give a way for lv2 hosts to have a built in drum synth that can save its entire state (i.e. no need to go out to external tools and no need to save extra state). See the wiki (click the wiki tab above) for some screenshots. DrMr currently supports the following:

Control via midi
Scan for and load hydrogen drum kits (see note 3)
Multi-layer hydrogen kits (will pick layer based on that samples set gain)
Kit is set via an LV2 control (see note 1 below)
LV2 controls for gain on first 32 samples of kit (see note 2 below)
LV2 controls for pan on first 32 samples of kit (see note 2 below)
GTK ui that can select a kit and control gain/pan on each sample
Custom knob widget for GTK ui based on phatknob that is both functional and awesome looking. (see wiki for screenshot)
Sample grid can start in any corner of the window, to match the layout of your controller.

Hopefully coming soon:

Creating / Saving custom kits on a per sample basis using the GTK UI
ASDR envelope on samples (Will be automatable and controllable in the UI)

DrMr is a new project, so the code should be considered alpha. Bug reports are much appreciated.

The lv2unstable Branch

There is a branch of DrMr that has a number of new features, the most useful being that the kit loaded can be saved properly as a path, and so the issue described in note 1 below is no longer an issue. You can click the branch button near the top of the page and select lv2unstable to see more information.

The lv2unstable requires some new lv2 features not available outside the lv2-svn version at the moment, so it's living in its own branch, but it will be merged as the main branch when the required features stabilize.

Download

Only via git for now, just check out this repo

Compilation and Install

DrMr is built with CMake.

To build it simply do (from this dir):

mkdir build
cd build
cmake ..    (or "cmake -DUSE_NKNOB=OFF .." if you want old style sliders)

Then do:

make
make install

to install. There are some customizable variables for cmake. To see them do "cmake -L". The important ones are:

USE_NKNOB - Use custom knob widget for controls instead of the default gtk sliders. This defaults to ON. Try turning it off if you are experiencing problems, or just prefer the sliders.

SAMP_ZERO_POS - Controls where sample zero will position itself in the sample table. This is just the default value, and can be changed in the ui when DrMr is running. Valid values are:

0 - Top Left (default)
1 - Bottom Right (This will align with many drum machines and MIDI pads)
2 - Top Right
3 - Bottom Right

Any other value will emit a warning and use 0.

LV2_INSTALL_DIR - The directory to install the DrMr plugin to. To install to your home directory, use "~/.lv2" and clear the CMAKE_INSTALL_PREFIX. This defaults to "lib/lv2" (this is relative to CMAKE_INSTALL_PREFIX, which is usually /usr/local)

You can also use "ccmake .." or "cmake-gui .." for a more interactive configuration process.

A legacy Makefile is included, that will possibly work for you if you don't want to use cmake. To use it just do (from this dir):

make -f Makefile.legacy
make -f Makefile.legacy install

You'll need the following libraries to build and install DrMr:

DrMr scans the following directories for hydrogen drum kits:

/usr/share/hydrogen/data/drumkits/
/usr/local/share/hydrogen/data/drumkits/
/usr/share/drmr/drumkits/
~/.hydrogen/data/drumkits/
~/.drmr/drumkits/

If you want to add others, add them to the default_drumkit_locations array at the top of drmr_hydrogen.c

Note 1

As stated above, a goal of DrMr is to have the host save all the state for you. As such, the current kit needs to be a control. Unfortunately, string controls in LV2 are experimental at the moment, and not supported by many hosts (in particular Ardour doesn't support them). This means the kit needs to be set via a numeric control. DrMr specifies an integer index as a control to select which kit to load. A kits index is the order in which is was found. This means changing, adding, or removing hydrogen kits could mess up your saved index. Sorry.

You can figure out which kit is loaded by looking in the GtkUI at the bottom, or look at the print output from your host, as drmr will print the names of kits as it loads them.

Note 2

DrMr is currently using a static ttl file. This means I have to decide statically how many gain/pan controls to expose. I've settled on 32 for the moment, but that is arbitrary. At some point DrMr will probably move to using the LV2 Dynamic Manifest feature to expose the appropriate number of gain controls for the current sample set, although how force a host update of the manifest when the kit is changed is unclear (if you know how, please let me know)

Note 3

DrMr only currently supports a subset of things that can be specified in a hydrogen drumkit.xml file. Specifically, DrMr will not use gain/pan/pitch/asdr information. DrMr basically only uses the filename and layer min/max information to build it's internal sample representation. Values specified in .xml files will be used as DrMr begins to support the features needed for those values to make sense.

Crashing Ardour 5

I was playing DrMr Sampler with a MIDI controller, while suddenly Ardour crashed.
As I was running a debug build, here's the full GDB backtrace from Ardour-5.4.40-dbg:

wishlist:

At the beginning - thanks for this plugin. It will be a great thing.

I use / test it and I have some thoughts.

Triggers
Currently you can only change the "base midi note". I propose to create an array of triggers.

At the moment it looks like this:
nn = data[1];
nn-=baseNote;
trigger_sample(drmr,nn,data);

I propose to replace:
nn = trigger_table[data[1]];
if(nn>0){
nn--;
trigger_sample(drmr,nn,data);
}
/ / Samples in trigger_table numbers are increased by 1

"Sample a zero position" in this case would be unnecessary.
Table trigger_table for a each kit should be remembered (saved to a file).

Graphically this would look like a matrix: rows - midi notes (C2, C#2, D2...) , columns - sample number (or names).

Indicators play sample.
The topic has been exhausted in previous posts, so I will not be repeated.

And a little thing - to reduce the size of the wheel from 50 to 25 (or similar). But this is only my whim. ;)

I'm currently using Hydrogen and Ardour. This plugin is a positive revolution!
Very fan of you. With great interest I will be looking at further development DrMr.

Regards :)
Marcin.

Use digits instead of words to denote sample number

I find it easier to navigate a list of parameters when the use digits instead of words to convey numbers:

"01, 02, 03" is easier for me to read than "one, two, three"

Wouldn't it be a good idea to modify the DrMr Sampler LV2 plugin parameter names in such fashion?

This looks pretty confusing to me, I can't even tell if the samples are listen in order.

wishlist: activity LED for each sample

Hi!

I don't know if it makes sense, but I've tried drmr for the first time today. It was connected to an external MIDI keyboard, so I simply tried all the keys to trigger the samples.

If I would want to alter some settings (vol/pan), I would have to guess which key belongs to which sample. If you could provide a way to indicate an active sample, things would be considerably easier.

Maybe add an LED between the two knobs or change the box' background colour upon activity, maybe even some colour gradient depending on the currently played velocity.

Cheers

Make use of Hydrogen mute groups

I often use mute groups in Hydrogen to make closed/open hihat sound like one instrument instead of two.
Looks like DrMr Sampler is ignoring them right now though.

Cannot handle symlinks

If the drumkit folder is a symlink drmr is not able to load it. Fails with:

trying to load: file:///home/falktx/.lv2/sfs.lv2/Audiophob/drumkit.xml
Unable to open file:: No such file or directory
Failed to load kit at: file:///home/falktx/.lv2/sfs.lv2/Audiophob
Passed a path I can't resolve, bailing out

These files definitely exist though:

$ file /home/falktx/.lv2/sfs.lv2/Audiophob
/home/falktx/.lv2/sfs.lv2/Audiophob: symbolic link to `/usr/share/hydrogen/data/drumkits/Audiophob'

and

$ file /home/falktx/.lv2/sfs.lv2/Audiophob/drumkit.xml
/home/falktx/.lv2/sfs.lv2/Audiophob/drumkit.xml: XML document text

Because of this drmr cannot load state in jalv and ardour3.

LV2 interfaces see kit option as an index instead of a name

When you load DrMr as an LV2 plugin within Qtractor, if you edit the plugin using Qtractors' interface, you can only see the drum kit index (integer), and not the drum kit title. This makes it pretty difficult to select which kit you want to use.

I don't know if it's possible to change this from DrMr - it might be a Qtractor problem. If it is, I'll submit a bug there.

drmr_ui.xml missing

joe@Joyce:~/building/drmr$ make
make: *** No rule to make target `drmr_ui.xml', needed by `drmr.lv2'. Stop.

new plugin gui

hi like your plugin it the best alterative to ez drummer or any of the others like it. I think it would be to have a new plugin gui like this

with a animated drum set
and a mixing board

pkg_check_modules(LV2 REQUIRED lv2>=.0.1.0) fails on windows with Visual Studio

As always cmake fails to prove it's worth of existence.
Such packages doesn't exist out of the blue if they are not with the source. And please use real build tools that has more than 0.0001% success of building the project.
For C look into nob.h by Tsoding - https://github.com/tsoding/musializer/blob/master/src/nob.h

UI doesn't work well on small screens

On my netbook, if there are any more than two or three rows of drums, then the bottom of the UI gets cut off, so I can't select a different drumkit. This probably wouldn't matter so much if all the kit controls were at the top, as I don't often need to change individual drums much.

It'd be great if the drums would spread out into more than 4 columns when the window was resized too, as this would allow easier access to most drums.

Allow custom MIDI mapping

I wish I could choose what sample listens to what MIDI note. A MIDI-learn style function for this would be great.

Select your first sound.
Press "MIDI learn" button for that sample
Hit a pad or key you want to assign to that sample
Repeat for all the samples you need!

Using hydrogen envelopes

I used Hydrogen envelope to shorten a Hihat, but when I loaded the drumkit in DrMr, it seems to be unaffected by the ADSR settings.

EDIT: I now realised it's a TODO feature, not yet completed.

Sample preview button

Loving the awesome sampler. Just what Linux audio needs right now (or at least, the part that I'm interesting in :D).

It would be really useful to have a sample preview button in the sample pane in the mane window. One reason is that if you're not familiar with the kit, then you really want to be able to check what it sounds like quickly and easily. Another is to check the sample gain and panning.

Just a small button near the sample title would be suitable - or you could even make the sample title a button.

update for gtk3

Hello, Just tried getting this to compile on ubuntu 20.04 . I am a programmer but lacking in Maekfile black magic!

Any possibility this will get updated?
Id love to be able to use hydrogren directly in ardour. Esp if it could fan out to multi tracks hint hint..

Avail for testing etc

No UI in QT5 apps

This plugin is indispensable. It works in latest Qtractor build with QT4 but chokes on big Hydrogen banks and forgets its bank in between reloads, but othewise everything is OK. Thanks a lot, this is a really cool piece of plugin.

In Qtractor built with QT5, the UI is broken : See http://www.rncbc.org/drupal/comment/6453#comment-6453 and no access to the banks seem possible...

Rearrange widgets (feature request)

Feature request to rearrange the mapping of pads 1 - 16, to align them with hardware
such as drum machines and MIDI pads:

DrMr 16

Hi Nick!

I love DrMr and how easy it is to use within Qtractor (as opposed to Hydrogen...). However, I liked the multi-channel capabilities inside Hydrogen (comes in handy when you want to sidechain or add effects to only the hi-hats or whatever), so I did some ugly modifications and turned DrMr into a 16 channel sampler.

This is my first open source contribution, so I don't know if I'm breaking any rules/etiquette, so I would be glad if you checked DrMr 16 through. Feel free to snap me on the fingers if you notice anything bad (not mainly the code... I know it's an ugly solution), no harm intended!

Warm greetings
Håkan Bernhardsson
