Editions

mmidi

 This is the original release. It comes with a visualizer and mouse + keyboard controls. It works from NT 3.51 up to the latest. Might also work in wine.

mmopt

 This is just a stripped down version of mmidi. No visualizer, no controls, just text and MIDI playing. Hardcoded MIDI device.

mmnolag*

 This is a special release. It tries to "minimize" the MIDI by stripping "unnecessary" events. It just works™

MorshuMidi / mmm*

 This doesn't belong in the mmidi line because it doesn't use mmidi code. This is written from scratch, everything stripped, very high performance. Also, quite small. Very few CPU cycles per note. Possibly the fastest available MIDI player.

Morshu-mmidi*

 This is MorshuMidi with mmidi's visualizer slapped on it. Includes a more advanced scrolling control than mmidi. Includes PFA mode (BPM-based scrolling). Possibly the fastest MIDI player with built-in visualizer.

mmvis*

 This is a derivation of Morshu-mmidi. It includes some extra features at the cost of slightly degraded performance. Still outperforms basically every other MIDI player out there.

MMVis / DFB*

 This is an attempt to create a Piano From Above clone for the Black MIDI community which aims to look similar to the original while outperforming it.

ExtremeMIDI / extremm*

 This is currently possibly the fastest and smallest MIDI player available. The original MorshuMidi was equipped with an extra processing thread, creating ExtremeMIDI. The new thread is capable of offloading the slow note event processing to itself, allowing the main thread to focus more on timing and real-time decoding instead of waiting for the synth to process the incoming events. This edition also comes equipped with smart noteskip, so if note processing takes too long then, and only then will it start skipping notes. The smart noteskip engine tries to keep noteskip disabled as much as possible to try to capture most of the melody as possible. *: these only work with OmniMIDI. Other editions support WinMM and TiMidity++ too.

mmidi controls

 - SPACE - play/pause - SHIFT+SPACE - pause without MIDI reset - UP/DOWN - slow down/speed up playback +- 0.01 - SHIFT+ UP/DOWN - slow down/speed up playback +- 1 - LEFT - set speed to 1x - RIGHT - hold to fast-worward at 10x - SHIFT+RIGHT - hold to fast-forward at ??? too fast speed - SHIFT+LEFT - reset MIDI (equal to pausing and unpausing) - SHIFT+Q - quit - CTRL-C or BREAK - emergency pause (not compatible with TiMidity++) below is Morshu-mmidi only - ALT+ UP/DOWN - adjust scroll value - SHIFT+ALT+ UP/DOWN - adjust scroll value 100x - ALT+RIGHT - toggle between 0 and -1 scroll speed - ALT+LEFT - set scroll based on current BPM Positive scroll speed means wait value/10000000 seconds per scroll. Negative scroll speed means wait -value * BPM * magic seconds per scroll. Zero scroll is fallback to mmidi behavior and is the most CPU-conservative. Too small bigger-than-zero values are too CPU-intensive. Use -1 or -2 instead.

DFB controls

 - CTRL-O - open file - CTRL-W - close player and stop - SPACE - play/pause - UP/DOWN - slow down/speed up playback +- 0.01 - SHIFT+ UP/DOWN - slow down/speed up playback +- 1 - LEFT - set speed to 1x - SHIFT+Q - quit - hold ALT for 1s - open settings - tap ALT - close settings Settings dialog options - UP/DOWN - adjust first option - LEFT/RIGHT - adjust second option - CTRL+ ARROW - adjust value in real time - SHIFT+ ARROW - adjust value in big steps - CTRL+SHIFT+ ARROW - quickly adjust value in real time - M - change piano key design (piano vs. all-same) and change first and second option - O - toggle between 128 key and 256 key - B - toggle "rendering" mode with no audio for use with Bandicam's variable framerate capture option - WS-AD-QE - "rotate" camera left/right, up/down, in/out - IK-JL-UO - "move" camera left/right, up/down, in/out - Y or Z - reset camera to 128key projection
