Drumgizmo Roadmap
Version ending with an even number are stability/bugfix releases (except 0). Versions ending with an odd number are feature releases that are potentially unstable.
Version 0.9.19
Feature release
Not yet a target release date.
Strip dead code in binaries.
Compile with dynamic libraries removed/hidden to force static linking.
Compile zita-resampler as a submodule
VST Makefile, add -Wno-c++11-narrowing
Add missing nativewindow_cocoa.mm to distfiles.
OSX:
Create
.dmgs for OSX deployment.
(deva)
Make OSX bundle with LV2 (See
DPF / ask falktx)
Make OSX bundle with VST (See
DPF / ask falktx)
Make sure DrumKit.clear() also clears metadata.
Plugins:
Consider adding resampler quality knob to the UI.
(unassigned)
Show played notes in clicky kit.
(chaot4)
Add
LV2 port-group support to be able to name the outputs according to the drumkit channel names.
(unassigned)
Add default midi map to drumkits which is then automatically loaded when drumkit file is loaded
(chaot4)
Add default drumkit to user settings?
(chaot4)
Add MIDI learn feature.
(chaot4)
Add functionality to save/export learned MIDI map to midimap file.
(chaot4)
Display last played MIDI note
(chaot4)
Add sample pitch modifier
(chaot4)
Add per instrument volume control.
(chaot4)
Make file browser a more pleasant experience
(chaot4)
Add “Velocity translation” module in ui for the following functionality:
(chaot4)
Velocity curvature adjustment (up/down)
Velocity floor adjustment
Velocity ceiling adjustment
The point of all of these is to adjust any given drumkit to match the expected sound output from a midi drum loop you might have acquired elsewhere. The drumkits differ in where the hits are placed and as such an internal adjustment might be needed for the midi to sound as expected when played through any particular kit.
-
-
Add support for opening links in external browser
(unassigned)
Add support for setting mouse cursor.
(unassigned)
Add selection by mouse and keyboard (shift+arrows) in lineedit.

Midifile instead of (or also) libsmf (suggested by Chris Share - cpsmusic).
(unassigned)
Other:
-

(deva)
Parse beginning of xml files in order to determine if they are a drumkit. Hide if not. Extend drumkit parser with some function that determines if current file is of proper format (eg. for drumgizmo format root node is drumkit).
(suhr)
Improve dgreftest to use xml as input including files, seed as well as config as xml like the plugins.
(unassigned)
Make test suite of mid/wav/xml files exercising all kit features.
(unassigned)
If you have named jack output channels in your jack drumgizmo client using jack metadata to suggest a port sorting order for e.g. QJackCtl is now possible (ask nils)
Add “two output channels mode” which should be super convenient for e-drum kits
(chaot4)

-u
.
(unassigned)
Add “Export” and “Import” buttons and functionality to the UI.
(unassigned)

(unassigned)
Make hihat openness matrix control port. Look up samples in a two dimensional array rather than a one dimensional depending on velocity and openness instead of just velocity. This could also be used for “off-axis” on a snare or similar and could potentially be use with more-than-2 dimensions.
Wayland UI support

Little cute drumkit in inline display where the drums light up when corresponding note is played.
Enable unit-tests on (at least) win64

Make DrumkitCreator cross-platform:
-
Make our own wav header parser for the MemChecker kit size calculation.

Refactoring on PowerList (midifile-refactor branch)

Make midimap load only happen through setting settings.midimap_file in MidifileInputEngine.
Create new Engine class and move all audio-inner-loop code there to better indicate where we can use blocking calls/locks and where we can't.
(deva)
-
Make unit tests run on OSX.
Use common bin-version for plugins (VST: setUniqueID() and LV2: ttl:microVersion and ttl:minorVersion)
Remove instrument name from instrument files, since it is used by the drumkit to map through midimap.
(unassigned)
cli client tasks:

(unassigned)
Make rendering progress in cli client when rendering midi file to wav.
(suhr)

When first loading a kit, the initial path should be a “drum kit path”.
Initial settings for humanizer and relating values should be configurable.

(unassigned)
'git:/ /' support for annonymous pull.
(unassigned)
Add keyboard shortcuts to UI (Escape → filebrowser, tab → jump to next element)
(unassigned)
-
ENGINE: When recieving midi input, make it possible to restrict it to a certain midi channel (0-16?). As reported by “swbeeton” on irc on 22may2014. Ardour can output to only one midi channel so it is possible to have both a keyboard and an electronic drumkit connected on the same midi interface. But since DrumGizmo recieves input on all channels, it also reacts to the midi keyboard input.
Look at Aubio for beat onset detection.
(unassigned)
Add bypass button in the
GUI reflected in the DAW
lv2. It should disable the engine entirely not just mute the outputs.
(unassigned)
Split up
GUI engine code and plugin
GUI implementation.
(unassigned)
-
Display if
OSS is enabled by default based on host
OS.
