AlsaModularSynth — Synthesizer
and Effect Processor
and Effect Processor
AlsaModularSynth (from the package
alsamodular
) is a digital replica of an
analog modular synthesizer. The program has a JACK interface and can load all
kinds of LADSPA effect plug-ins. Thus, it can also be used as a versatile effect pro-
cessor.
kinds of LADSPA effect plug-ins. Thus, it can also be used as a versatile effect pro-
cessor.
Enter
ams
to start AlsaModularSynth from the command line. The parameter
-j
activates the JACK mode, provided the JACK engine
jackd
is running (see The
JACK Audio Connection Kit on page 187). The required port connections can be
established with QJackConnect. Individual ports are generated for each PCM
module in the JACK mode. AlsaModularSynth only appears in the list of QJack-
Connect if at least one PCM module exists.
