Hi! I'm quite new in using Ubuntu, and then of course new at using
Rosegarden. I actually managed to set up JACK(?), which I read was
necessary in order to get my Focusrite Saffire (firewire) working.
So far, so good. I even found the midi-bank to my Roland RD-700sx. I
can choose sounds from my keyboard, and record audio.
I hooked up my bass guitar, and was able to record.
But what I couldn't find, was a button where I could turn on
monitoring. I might be a poor bass player, but I actually prefer to
hear what I'm recording, as I record. Not just afterwards, when
listening to the playback of my recording.
I have searched the user manual for Rosegarden, and tried to google
the topic, but with no luck.
To be able to monitor the input which I am about to record, and during
recording, is important. I can watch the input level under the
Instrument Parameters, and adjust both input and output of the audio,
but not hear anything.
Hopefully, one of you clever developers or hard-core users out there
can help me with this?

Yeah, monitoring is paramount to proper home recording :)
I never used audio in RG but I can think of a couple of options that involves jack. There may be a monitoring option in RG but again, I do not know.
Hardware monitoring: don't know whether you card has the capability. Have you checked if you can enable such a thing from the ffado mixer ? I guess since you run a firewire based card, you can control it via the ffado mixer. I use h/w monitoring as well with my RME HDSP card, which is controlled with TotalMix (dedicated mixer app). So I would think something similar could be available for ffado managed cards.
If h/w monitoring is not possible, then you can always use jack, albeit it would require a low latency setting not to be bothered by the processing delay while you are playing.
Let's say that you are using Qjackctl for controlling jack.
You have a connection window. The system:capture_x port corresponding to your bass guitar can be connected directly to your system:playback_x ports where you have connected speakers or headsets or whatever monitoring device you use.
In general, you can have multiple port connection (many-to-many relationship). So just adapt your jack patchbay according to your needs.
but again, this solution requires a robust low latency setting. I find that below 5ms, this is acceptable. Hopefully, RG does latency compensation of the audio being recorded. I cannot say since I don't use the audio capability.
Håber, at det hjelper :)
