Getting Started

Install the software in your system

Install Xtractpler version from provided file. On Windows use .exe file installer. On Mac use .dmg file .

Setup you desired system audio input

On Windows select Stereo Mix as audio system input.
On Mac, use Soundflower (2ch) 

Prepare VST/AAX/AU or DAW audio

Set audio output to Stereo Mix on Window or Soundflower (2ch) on Mac, in your desired program.

Prepare VST/AAX/AU or DAW MIDI-in

Set the MIDI-in on channel 1 to receive messages (notes) from Xtractpler. For Mac, you may use IAC Driver Bus.

Authorize Xtractpler to access Mic in MAC

If you run Mac version, make sure to allow Xtractpler access to Microphone.

Determine the capture mode: Drum, Sound, Live or Speech

Screen%20Shot%202020 05-27%20at%205.59.07%20PM

Xtractpler offers forth different capture modes: 
Drum mode aims to audio capture that comes as result of an internal/external MIDI sound generator where Xtractpler will send MIDI notes at different velocities and where sounds generated are no longer than 15 seconds. The delay between each MIDI note triggering is about 500ms.

Sound mode is useful when attempting to capture other audio type (like drones, strings or any other sound with long decay) by sending MIDI notes at different velocities where sound is not longer than 100 seconds. In this case there is a delay of 5 seconds between each MIDI note triggering after MIDI Note Off sent.

Live mode instead of sending MIDI notes, it listens from audio incoming from system audio input port. It records and request user to generate sounds on expected velocity during configured duration time for each sample. The progress bar will indicate the time left for capturing for each sample. On each sample completion, the progress bar will become green and wait 2 seconds before starting the capture of next sample velocity. 

Speech mode is similar to Live mode with the difference of capturing only one audio file where the intention is to reduce the silence between spoken phrases and removing initial silence. In this case, Xtractpler ignores the MIDI note, samples quantity and duration configured in Configuration window. Only the name is taken into account.

Configure the notes & velocity curves for triggering the notes

Screen%20Shot%202020 08-04%20at%208.45.10%20PM

Use Xtractpler configuration window to setup your MIDI output device. Xtractpler will use the selected MIDI Channel to send MIDI notes.
Select output folder where to store produced files once captured by Xtractpler. Xtractpler will use the OutputFolder as PATH to then create a subfolder with the name configured as “Name”. in this case EZDrumKit will be created under /Volumes/EVO850/SMP folder.
Configure sampling frequency, bit rate, type and if you want to capture the store output wav files in stereo or mono.
Use Xtractpler grid to setup samples information such as: name, MIDI note, quantity of samples, time duration, note velocity range (i.e. max and min values), velocity curve (i.e. Linear, Exponential or Logarithmic distribution) as well as if the sample is enabled/disable for capturing.
Use right grid icons to add, edit or remove samples information. 
Click any cell of the grid to edit its value.
Use Save As to persist your configuration on a different configuration file.
Use Load config button to recall previous saved Xtractpler configuration file.
Click on Apply Changes to apply all values from this window (this will save values in active configuration file and will close the window to get back to Xtractpler main one).

Sending MIDI notes to VST/AAX/AUs

Use Xtractpler Capture Audio button to start audio capture.
MIDI notes will be sent to MIDI VST/AAX/AUs listening on such MIDI device and channel.
Xtractpler will record audio from your default system input selected (*) and records temporary audio files in output folder.
Depending on how many samples are required, time of this process may vary.
Xtractpler progress bar at the bottom indicates current status of the process.
Useful information is also print on the console (white text area).
During capturing process buttons are disabled to avoid any interference, however Abort button can be activated.
Green circle icon on the top right corner shows the configuration window.
Red circle icon on the top left corner close Xtractpler and interrupts its process.
