This window allows you to edit both MIDI and audio mixes with unlimited undo/redo capabilities. When saving a mix to a file, the following items are stored in the qmidi project file:
The channel On/Off state is stored in the library (Info window -> Disabled Channels), so these buttons are only enabled if you load a file from the library. A live application of this approach is the ability to create multiple instances of a song with the option to mute specific instruments depending on the band's composition. Many small bands and artists (soloists, duos, etc.) have switched to multitrack accompaniment, one of the advantages of which is the ability to mute, for example, the guitar track if a guitarist is playing, or the bass track if a real bassist joins for a larger concert, etc.
The Mute and Solo states are never saved and remain unchanged until you quit the application.
You can choose between three save modes:
The MIDI mixer allows to view/change most sound parameters in real time. You may change the instrument, volume, balance (pan), reverb level and chorus level on any of the 16 MIDI channels. If the READ button is highlighted (default), all the parameters are read from the MIDI file and sent to the output device. Also, the values of every control of the mixer window are updated in real time.
PC (program changes) are displayed in the form [PC+1.CC0.CC32] followed by the instrument name. CC0 and CC32 are displayed only if their values are non-zero.
NB: The name is taken from the instrument list of the chosen device (SC55 mkII, SC88 or SC88 Pro) and may not correspond to the real instrument name if you are using another device.
To make your own mix, you may follow these steps:
Use the PATCH popup menu to switch between SC-55, SC-88 and SC-88 Pro instrument lists (maps). Use the SC-55 map unless you're sure that your MIDI device supports SC-88/SC-88 Pro patch changes.
The GS Effects are an extension of the mixer and allow you to view/change master GS effects parameters. These settings will have effect only on GS compatible MIDI devices, but changes will be saved into the mix.
The audio mixer allows to control the on/of state and the volume of up to 16 audio channels without the need of an external mixer. Channels can be linked as stereo pairs.
If the MIX button is activated, the 16 channels are routed to outputs 1-2 or 3-4, otherwise they are sent to the respective discrete channel (as in QMidi v2).
Outputs 3–4 are useful for separating certain audio from the main audio stream. For example, if the audio file contains a click track, you may want to route it to outputs 3–4, which can be connected to the musicians’ headphones.
Click this button to open the audio format info drawer.
This section appears in the INFO drawer and allows you to precisely synchronize audio and MIDI playback. It is hidden when no MIDI file is linked to the current audio file.
To create a new mute group:
Tip: You can easily add a menu shortcut to a group (or any menu in QMidi!) by following this guide.
If this option is checked, any patch variation (CC0/CC32) not listed in the current selected map will be ignored. This will fix the "No Instrument" error (and silent sound) which may occur on external MIDI Sequencers when an unavailable instrument is selected.
Saves the current audio mix as a preset that you can recall with the "Load Preset" action.
Loads the saved preset, if any.
Loads the stereo preset. This default factory configuration sets all volumes to 0db, pans channel 1 to the LEFT output (1), channel 2 to the RIGHT output (2), and links channels 1 and 2.
The current mix will be saved and used as the default mix for songs that do not already have their own saved mix.
