Features:

  • Converts to MP3 or Ogg Vorbis
  • Maintains directory structure from original library
  • Takes advantage of multicore processors
  • Can copy or ignore files by extension (album art, log files)

Impro-Visor ~ Jazz Improvisation Adviser


Impro-Visor (short for “Improvisation Advisor”) is a music notation program designed to help jazz musicians compose and hear solos similar to ones that might be improvised. The objective is to improve understanding of solo construction and tune chord changes. There are other, secondary, things it can do, such as improvise on its own. It has also been used for transcription. Because rhythm-section (e.g. piano, bass, drums) accompaniment is automatically generated from chords, Impro-Visor can be used as a play-along device. Now having a wider array of accompaniment styles, its use is not limited to jazz.

OpenSebJ ~ Real-time Sample Mixer


OpenSebJ is a free real time audio sample mixer that runs on Microsoft Windows. The source code for OpenSebJ is released under the GNU General Public License.

  • Supports loading of 255 audio samples, in wav format, which can be played in real time.
  • Sample properties such as volume, pan and frequency can be adjusted individually for each sample. (even during mid-play)
  • A composition tool is provided and presented in a familiar multi-track sequencer environment. Looping compositions are also supported.
  • Samples can be linked to keys on a keyboard and triggered in real time when a key press occurs.
  • Each sample can also have the play cursor position adjusted while the sample is playing, to provide a virtual needle to be moved.
  • Stream to disk recording, allows all audio played from OpenSebJ to be saved.
  • Pitch shifter roll, allows an order to be set up, so that each time a sample is played, the next pitch shift in the sequence is undertaken before the sample is played. i.e. set up a sample to key ‘1’, then set up a pitch shift sequence, high, mid, low, higher, etc. (using frequency values which are transposed onto screen ‘ranges’ to allow easier utilization).
