Hydrogen Ardour questions

[1.618]

I have an issue with the volume for indivdual tracks within ardour..

open jack
open hydrogen
open ardour
connect via jack, I can hear hydrogen, master level meter works as expected
add new track in Ardour, labelled 'drums'
edit new track in mixer and select hydrogen as the input
new track level meter shows sound is coming through into desired track

but

when i slide the volume for track 1 down, there is no difference in the output, only the master affects the volume...

I'm probably missing something really simple..

I only get sound when hydrogen is connected to ardours master inputs as well, i assumed if i wanted to record on track 1 i should plug hydrogen into ardour track 1 input in jack but no sound comes through, the meter shows sound passing through but nothing comes out of the speakers and moving the slider makes no difference to the meters level

so how do i configure ardour so that the volume slider for track one alters the sound i am hearing?


and

How do i configure hydrogen to sync with Ardour so when i hit start in ardour, hydrogen starts playing too.. is that a midi thing? I've looked online but nothing has helped... I'm using linux mint 16, which is based on ubuntu 14.04

Sync Hydrogen:
On Hydrogen you have to enable JACK transport. It's the "J. Trans"-Button right of the BPM-display.
With Qtractor it then works out of the box. With Ardour I had no success. Ardour is too complicated for me. I bought it to support Open Source but I don't use it.

Volume control:
Start Ardour
Choose/create a bus
Select Hydrogen's out_L and out_R as inputs
Hydrogen has an additional connection to system/playback_1 and _2. Disable it.
Now Ardour's faders works fine.

That worked, Had to select the jack driver but everytime i did, the driver just reset to 'auto', so i made a change to the hydrogen config file and the "J-Trans" button appeared, didn't start with ardour, lol...

Qtractor looks pretty cool, seriously tempted to have a play with it.

This one doesn't work, I'm not sure where the extra connection is that you mention, there's nothing in jack and i can't see anything in hydrogen.... still have no control over the volume of the individual tracks, just the master,

To avoid having direct audio connections from Hydrogen to System uncheck
Tools -> Preferences -> Audio System -> Connect to Default Output Pair

See attachment how ardour looks like with the proper connections from Hydrogen to an audio bus.

bluebell's suggestion works for an audio bus but if you want to connect hydrogen to a track (so you can record hydrogen to ardour), it is true and normal that the track fader doesn't affect the input level. To capture a higher level in ardour's track you need to rise the output level in hydrogen.

A different thing is monitoring. If you want that ardour playbacks the audio coming into an armed track (or while you are recording to it) you need to tell ardour to do so. (Ardour does monitoring or similar. Sorry, I am still using ardour2). In this case, the fader will affect the output of the track (but never the input).

Thanks for the replies, I found my cause of my problem was that i needed to check 'ardour does monitoring' instead of hardware doing it, now i can adjust the output of each track as i wanted.

I have unchecked the 'default output pair' in hydrogen a well
