The home of QJackConnect

Here you can download a QT based patchbay for the JACK Audio Connection Kit .

Download QJackConnect 0.0.3b

Old versions can be accessed via FTP .

AlsaModularSynth now supports JACK as well. When starting the program with the -j or --jack option and loading one of the example patches, all PCM In / Out modules are automatically converted into their JACK counterpart.

Download AlsaModularSynth 1.5.5

I have also written the tiny FM synthesizer jack_miniFMsynth.c which is both a JACK client and a client of the ALSA sequencer system. This example client is based on the example miniFMsynth.c of my ALSA 0.9.0 HOWTO .

To compile jack_miniFMsynth just type
  cc -o jack_miniFMsynth jack_miniFMsynth.c -ljack -lasound -lm
jack_miniFMsynth takes several parameters:
  jack_miniFMsynth <MIDI channel> <FM> <harmonic> <subharmonic> <transpose> <a> <d> <s> <r> 
<MIDI channel> MIDI channel for NOTE events
<FM> Strength of the frequency modulation
<harmonic> Harmonic of the master oscillator (integer)
<subharmonic> Subharmonic of the master oscillator (integer)
<transpose> Note offset for both oscillators (integer)
<a> <d> <s> <r> Attack, Decay, Sustain, Release

Some examples:

Harpsichord ./jack_miniFMsynth 0 7.8 3 5 24 0.01 0.8 0.0 0.1
Bell ./jack_miniFMsynth 0 3.5 7 9 0 0.01 0.2 0.3 1.5
Oboe ./jack_miniFMsynth 0 0.7 1 3 24 0.05 0.3 0.8 0.2

jack_miniFMsynth reacts on pitchbender and modulation wheel events. Since it is not optimized with respect to performance (you would e.g. never call the expensive sin function in a "real" program), you might have to decrease the polyphony in the source by modifying the #define POLY.
