# Multi-Sampler x48 DirectOut

Detailed: LSP Multi-Sampler x48 DirectOut (SZ48D)

Formats: CLAP, GST, LV2, VST2, VST3

Categories: Instrument

Developer: Vladimir Sadovnikov

Description:

This plugin implements 48-instrument MIDI sample player with stereo input and stereo output. For each instrument there are up to eight samples available to play for different note velocities. Also each instrument has it's own stereo output that makes possible to record instrument outputs into individual tracks.

## Import SFZ files feature

The plugin allows to import the limited SFZ files..

All regions are sorted and grouped by the group label and the note number taken from the SFZ file as a single instrument. If the number of instruments is more than 48 then all instruments above this count are ignored.

The import of embedded into SFZ audio files is also supported.

The supported list of opcodes:

- #define - variable definitions;
- #include - file includes;
- default_path - the default path the samples are located;
- note_offset, octave_offset;
- sample, including the built-in samples specified with <sample> command;
- group_label - can be used to group instruments into a single instrument;
- key - specifies the MIDI note assigned to the instrument;
- lokey, hikey, pitch_keycenter - used to determine the MIDI note if the 'key' is not specified;
- lovel, hivel - for velocity;
- lorand, hirand - used as a velocity if lovel and hivel is not specified;
- tune - fine tuning;
- pan - panning;
- volume - volume correction.

## Import Hydrogen kits feature

The plugin allows to import Hydrogen drumkit files by selecting 'Import' → 'Hydrogen drumkit file...' menu item. The file dialog allows to select the desired Hydrogen kit and import.

Additional to this feature, the Override Hydrogen kits feature is also provided and can be enabled via the 'User paths...' menu item or the 'UI behavior' → 'Override Hydrogen kits' menu item.

The main idea of the feature is following.

Additionally to the usual Hydrogen drumkit installation paths, user can specify additional drumkit installation path in the 'User paths' dialog. This will trigger automatic rescan of Hydrogen drumkits on each change of this parameter. All found drumkits will be available in the 'Import' → 'Installed Hydrogen drumkits' menu.

User also can specify the 'Hydrogen drumkit override path' that will be used to search for configuration files that will override the original Hydrogen drumkits.

If the 'Override Hydrogen kits' option is set, the behaviour of the plugin is the following.

When loading hydrogen drumkit via the 'Import' → 'Hydrogen drumkit file...' menu item or selecting one of the drumkits listed in the 'Import' → 'Installed Hydrogen drumkits' menu, the plugin removes the base path of the selected file if it matches one of the following paths:

- Typical hydrogen drumkit system installation paths (only when importing from the list of installed drumkits):

- /usr/share/hydrogen
- /usr/local/share/hydrogen
- /opt/hydrogen
- /share/hydrogen

- Typical hydrogen drumkit user paths in user's home directory (only when importing from the list of installed drumkits):

- .hydrogen
- .h2
- .config/hydrogen
- .config/h2

- The 'User Hydrogen kits path' if it is specified.
- The 'Override user Hydrogen kits path' if it is specified.

If the base path has been successfully removed, the plugin tries to search the file with the same relative path but the different extension ('*.cfg') in the following directories:

- The 'Override user Hydrogen kits' path if it is specified.
- The 'User Hydrogen kits' path if it is specified.

If the corresponding configuration file was found, the plugin uses this file for loading drumkit settings instead of the original Hydrogen drumkit file.

Also note that 'User Hydrogen kits path' and 'Override user Hydrogen kits path' allow to use system environment variables for path substitutions. For example, the following value:

    /path/to/kit/${KIT_NAME}

Will be interpreted as:

    /path/to/kit/my_drumkit

If the system environment variable 'KIT_NAME' is set to 'my_drumkit'.

## Configuration

Controls:

- Bypass - hot bypass switch, when turned on (led indicator is shining), the plugin does not affect the input signal.
- Workspace - combo box that allows to switch between instrument setup and instrument mixer.
- Direct output - set of buttons that allow to control the behaviour of all direct outputs:

- Gain - the loudness of the instrument is also applied to direct output signal.
- Panning - the panning of the instrument is also applied to direct output signal.
- Listen - the sound of sample preview is also fed to direct output.

'Instrument mixer' section:

- Enabled - enables the corresponding instrument.
- Gain - the volume of the instrument in the output mix.
- Direct Out - enables the output of the instrument to the separate track.
- Pan Left - the panorama of the left channel of the corresponding instrument.
- Pan Right - the panorama of the right channel of the corresponding instrument.
- MIDI Number - the MIDI number of the note associated with the corresponding instrument. Allows to change the number with mouse scroll or mouse double click.
- Note on - indicates that the corresponding instrument has triggered the MIDI Note On event.
- Listen - triggers the listening of the audio preview of the instrument.
- Stop - stops the listening of the audio preview of the instrument.

'Instrument' section:

- Channel - the MIDI channel to trigger notes by the selected instrument or all channels.
- Note - the note and the octave of the note to trigger for the selected instrument.
- MIDI Number - the MIDI number of the note for the selected instrument.
- Group - The group assigned to the instrument. The sample playback will be stopped for all instruments in the same group except the one's that has triggered the Note On event.
- Note off - when enabled, turns off sample playback for selected channel when the Note Off MIDI message is received. The sample fade-out time can be controlled by the corresponding knob. The behaviour is different, depending on the loop settings and muting settings. If the loop is enabled for the sample, then receiving MIDI Note OFF event will just break the loop and play the rest of the sample if muting is not set. If the instrument muting is set, then it will fade-out the sample.
- Dynamics - allows to randomize the output gain of the selected instrument.
- Time drifting - allows to randomize the time delay between the MIDI Note On event and the start of the sample's playback for the selected instrument.
