MultitrackStudio includes a disk-streaming sampler. Samples can be played direct from disk, so patches can be larger than the amount of RAM memory available.

You can load a sample library using the Library box.
The Import... option allows for importing .sf2, .sfz or .gig files, as well as MultitrackStudio's .zptc and .ptc files.
The Export... option exports the library to .zptc format. You can use this to move a library to a different computer for example.

The Patch box can be used to pick one of the patches the library provides.
Edit patch... invokes the Patch Editor.

The controls in the Controls section override the values stored in the patch (as set by the Patch Editor).

Tip: simple patches, containing just one sample, can be created easily by dragging an audio file from File Explorer (Windows) / Finder (Mac) to a MIDI track's Instrument Slot. You can also drag the selected part of a track editor or clips from the Clip Shelf to an Instrument Slot. A Sampler will be loaded in the Instrument Slot and a patch will be created for it. To use the patch in other songs you need to export the library and import it again.

The Sampler supports the following MIDI messages:

  • Note On/Off
  • Modulation (cont. 1)
  • Volume (cont. 7)
  • Pan (cont. 10)
  • Expression (cont. 11)
  • Sustain (cont. 64)
  • Legato (cont. 68)
  • Brightness (cont. 74)
  • Pitch Bend
  • MIDI 2.0 per-note pitch bend
  • MIDI 2.0 per-note modulation

Tip: to use per-note modulation with an MPE keyboard you can use the Keyboard Mapper. Set it up to map per-note aftertouch or per-note brightness to per-note modulation.

If the track has multiple MIDI streams the Sampler uses only the first stream.

The Sampler responds to messages on all MIDI channels, so the Channel value typically doesn't matter. It does matter if you're recording using the Keyboard Mapper's split option or multiple keyboards: in these situations you want only messages received on this channel to be recognized.

The Output button, available if the patch uses multiple outputs, pops up an 8 channel output mixer. This is typically used for drums. In the Pro edition these output channels are available as sidechain sources in other tracks.

The Options menu offers some settings:

Note: the Sampler does not support all the features .sf2, .sfz or .gig file can use. Differences include:

Under the hood
Imported sample libraries are converted to MultitrackStudio .ptc format patches. Each library gets its own folder which has the same name as the library ("MyPiano.sf2" ) for example. You can change the location of these folders in the Studio-->Preferences window. The audio samples themselves are stored as losslessly compressed .gjm/.gjs files. so the converted libraries typically use significantly less disk space than the originals. Libraries can be exported to .zptc format, this is a .zip file containing the .ptc file(s) and the samples used.
