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:
This (lv2unstable) branch of DrMr uses the lv2-atom and lv2-state extensions, which are both experimental lv2 extensions. As such, you'll need to have the svn version of lv2 installed (see [here](http://lv2plug.in/trac/wiki/SVN_repository) for info about how to install lv2 from svn). You'll also need a host that supports these extensions. Known working hosts are [jalv](http://drobilla.net/software/jalv/) and [ardour3](http://ardour.org/download_full), both from svn (i.e. Ardour3-beta3 won't work). Using these new extensions allows DrMr to have a number of new and planned features.
The intention is to have this version become the main stable version as the lv2 spec stabilizes and more hosts support the required extensions.
New features include:
- Kits are now selected via their path and not the hacky integer port as before
- The kit path is now saved and restored using lv2-state, so you can install/remove/modify hydrogen kits and your state won't be messed up.
- No need to scan kits in the plugin core so the plugin loads faster
- Loading of individual samples into each slot (so you can tweak the kit to use your own samples). New sample locations will also be saved using lv2-state so modifications will be persistent.
- New kit creation and saving (a bit further down the road)
One thing to note is that the kit index port has been removed. This means if you have projects using the master branch version of plugin you should note the kit externally as that state will not be reloaded.
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)
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):
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)
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.
