For educational purposes I have sampled a small
number of short pieces for (classical) double bass. As I know that Play Alongs
for classical double bass are hard to find (in contrast to the saxophone) I
include these midi files here. Please note that these files don't aim at
offering superior musical quality: they just offer co-players (second voice or
first voice in a duo) or a piano or cembalo accompaniment. Midi files are not
sampled like MP3 files! The quality you hear is extremely dependent on the
quality of the synthesizer on your soundcard. Btw: some media players
add controller events (vibrato) to my Midi files. I found this problem with the
media player in the Firefox browser. My Midi files don't contain controller events.
With any good Midi sequencer you can eliminate a voice and create thus a "play-along" version of the files. If you don't like the keys I have choosen (the keys are not alway the original ones) you may also use a sequencer to transpose the MIDI events. The tempos I have selected are generally slower than the tempos to be found in the scores. The normal media players are not sufficient to change the tempos or to transpose the keys: you need a Midi sequencer to do that.
You will find many of the MIDI interpretation functions in my own software HUMidi. You can download this program here (1.5 MB).
