Hi,
Thanks for reporting this.
I shipped drumgizmo-0.9.10 with the test engine deactivated, as the tests
weren't passing and upstream wasn't making heavy use of them. I should
have removed the mention in the manpage.
I also asked upstream about this, and they confirmed the test engine
was
Package: drumgizmo
Version: 0.9.10-1
Severity: normal
Dear Maintainer,
man page and usage string both show "test" among the available input
engines, however trying to use it fails with an error message:
$ drumgizmo --inputengine test
[EngineFactory] Unsupported input engine 'test'
Invalid input
