[linux-audio-dev] soft synth as a plugin

[Tommi Ilmonen]

Hi.

Sorry to come in very late. The Mustajuuri plugin interface includes all
the bits you need. In fact I already have two synthesizer engines under
the hood.

With Mustajuuri you can write the synth as a plugin and the host is only
responsible for delivering the control messages to it.

Alternatively you could write a new voice type for the Mustajuuri synth,
which can lead to smaller overhead ... or not, depending on what you are
after.
