Introduction
Freebee (workname Lush) is a software synthesizer created by Mike
Janney, aiming to emulate the classic Roland TB-303 Bassline.

    * Roland TB-303 Emulation
    * Pulswidth modulation
    * Suboscillator 
    * 3 different filters, 18dB, 24dB diod ladder simulations, and
      additional 18dB LRC filter simulation
    * Frequency Modulation 
    * Equalizer and hipass filter (bass cut)
    * Tube and linear distortion
    * Simple 6 track drum sequencer
    * Delay unit with BPM sync, panning and adjustable delay
    * Reverb unit


The development of the software began in 1998, during the first big boom of
software synthesis. 


Why another TB-303 Emulator
We needed a piece of software for our music projects, and didn't want to
waste money buying commerical software, or use a crappy emulation.

Release Notes / Disclaimer
This is an incomplete software package. Development of this program has
been discontinued due to loss of sourcecode in a harddrive crash. All
that remains are the executables which can be downloaded here. This
program may be usuable or not, it depends on the users patience. This
software is musicware meaning if you create something with it, the
author needs a copy of the music or a link to where the music can be
downloaded. Package may be redistributed as long as the contents are not
changed.

Specifications
A parametric model for the synthesizer was created using the original
schematics. Extensive fine tuning of the parameters was done by using
audio samples from various sources. Approximately 600 megabytes of
uncompressed audio data was collected and analyzed to create the best
possible emulation given the model.

Installation
After download, simply create a directory and unzip the files.

Requirements

    * Windows 98, Windows 2000 or Windows XP
    * DirectX 7.0 or later
    * Pentium 133MHz or faster. 

Manual
The program is small and selfexplainatory. Required knowledge is how to
program the bassline. This should be easy to grasp using the demo
patterns included in the package. Some things worth mentioning though:

    * Oscillator->Uniform Pulswidth allows the user to set the a static
      pulswidth of the square waveform. This results in a more hollow
      sound, which can sound more realistic in some situations. 
    * Filter->FM will activate a filter modulation, with the waveform
      being the modulation source.
    * Machine->Animate should never be activated, it can cause the
      program to crash.
    * The zero button on the bassline causes a jump to edit note zero in
      the current pattern.
    * The pitch mode button will when activated advance to the next note
      in the pattern when a note pitch is changed.
    * Pressing key r on the keyboard will randomize the pattern.
    * Pressing key a on the keyboard will switch all notes off in the
      pattern.
    * Some keys altered the emulation in certain ways, but I lost the
      source and don't remember what they were. If you find something
      please email me.
    * To edit parameters in the drum sequencer, push a button and
      carefully drag the mouse up or down.
    * The V (volume) and P (panning) buttons in the drumsequencer don't
      work. The S (shuffle) button works incorrectly.
    * To load a sample, click the <No sample loaded> filename field to
      bring up the file requester. Only Mono 44.1kHz wave files supported. 

Known problems

    * Sometimes the sound is static or locks up. Go to the menu
      File->Buffer Settings, and adjust the buffer size. Sometimes the
      problem will solve itself just by clicking Ok
    * The play song button doesn't always work. 
    * The VCA (voltage controlled amplifyer) isn't completely accurately
      emulated.
    * Sometimes the drumsequencers tracks get out of sync while editing
      drum patterns. Stop the sequencer and start again to solve the
      problem.
