[Rosegarden-user] An oddity!

2015-06-13 Thread Abrolag
At startup, and when loading new files, Rosegarden sends a 'reset all' message.
Is there any way to stop this?

The particular scenario that had me puzzled for a while is as follows:

I have a Yoshimi file with a set of voice parameters and a Rosegarden one with
a complete song project

I load up Yoshimi and open its mixer panel. The instruments are there but all
the volume and pan setting are the defaults.

I load up Rosegarden and see all the sliders move to the positions as set by
Rosegarden, but then instantly revert to the defaults!

If I run exactly the same files on a different (older) architecture the setting
are correct.

Has the order of these setting in Rosegarden changed at some point or possibly,
are they so close together that some timing issue in the machine can swap them
over?

My workaound at the moment is to duplicate the controls at the start of each
track (I always start at bar 2 to give me some wiggle room).

It looks like ChannelManager::setControllers() might be the one doing 
 this.  Are you using the auto channel feature?  This appears in the 
 Channel field in the Instrument Parameters box for each instrument. 
 If so, try setting the channel to fixed (for each track/instrument) 
 and see if that clears it up.
 
If you need the auto channel feature and the above clears the problem 
 up, then this might be an auto channel bug.

Hi Ted (that was quick!)

No, it's on fixed. I always use that, in fact I have that as my default studio
for all channels.

 Hello Folks. Steve Cook here:
 
 I am currently running Ubuntu Studio and need some help with adjusting a 
 midi/audio setup that involves the use of QJackCTL, Qsynth, VMPK and 
 Rosegarden.
 
 My current setup is as follows:
 
 http://i958.photobucket.com/albums/ae67/stevecook172001/current-rosegarden-setup_zpswhmrjbx5.jpg
 
 All of the above components are connected together using QJackCTL. The 
 way they work is: a midi tune is loaded into rosegarden and played. The 
 midi signals are first sent to VMPK, which displays which notes are 
 being pressed as the tune progresses. However, VMPK also passes these 
 midi signals through to Qsynth, Which, in turn, passes them to the 
 system speakers. Thus, the tune is heard throuigh the system speakers in 
 correct time with the keys that are being depressed in VMPk. Meanwhile, 
 I also have my real world external midi keyboard controller attached to 
 VMPK via Qjackctl. This allows me to press the keys on my controller and 
 have these key depressions appear on VMPK as well as have them also 
 passed onto Qsynth and then onto the system speakers. This means I can 
 simply follow what I am seeing on VMPK, in terms of input from 
 Rosegarden, on my midi controller. If I press the same keys on my midi 
 controller as are initially being pumped to VMPK from Rosegarden, the 
 midi song will sound in tune. If I do not, then it will sound out of 
 tune and I will be able to immediately auditorily (as well as visually) 
 recognize that. In short, then, this system allows me to learn a tune by 
 seeing and copying instead of having to read music.
 
 I have made a video of the above setup on You-Tube for a fellow user on 
 another forum. So, it might help to more easily understand my setup by 
 viewing it:
 
 https://www.youtube.com/watch?v=vRpDbe5hQJE (I am running Ubuntu Mate 
 over the top of Ubuntu Studio in this video, just in case you were 
 wondering).
 
 Okay, having explained all of the above, I now need to explain what am 
 trying to do with it in terms of extending it's functionality. My 
 proposed setup is:
 
 http://i958.photobucket.com/albums/ae67/stevecook172001/propposed-rosegarden-setup_zpsco8rvbpf.jpg
 
 I know, diagrammatically, how to setup the proposed arrangement, above. 
 What I don’t know is how to tell Rosegarden this is where I want the two 
 different tracks to go. Tthat is to say, the two different instruments 
 in the midi file are represented as two separate tracks in Rosegarden. 
 At the moment (with my existing setup), if I send the signal out from 
 Rosegarden to a single instance of VMPK, VMPK only picks up the first 
 track and ignores all others. I currently get round that by merging all 
 tracks in Rosegarden into a single track and then sending that to a 
 single instance of VMPK and this works fine. However, what I want to do 
 is to keep the tracks separate and send them to two separate VMPK 
 keyboards simultaneously, as per my second diagram. Is that possible 
 with Rosegarden? I should say, the reason I want to send the two tracks 
 out to separate VMPK's is twofold. Firstly, my two real world midi 
 controllers are 61 keys each and not full 88 keyboard controllers. Thus, 
 some tunes span a sufficient range of keys as to require me to play with 
 my left hand on one keyboard and my right hand on the other. That is to 
 say, I set my left hand controller to start three octaves lower than the 
 right one. Thus, they overlap by two octaves. Between them, though, I 
 get a full 88 key span. The second reason I want to send different 
 tracks to each of the keyboards is because some of the midi tunes I am 
 wanting to learn are for duets between two instruments. And so, my 
 proposed setup would allow me to effectively playback the two 
 instruments simultaneously from Rosegarden to two instances of VMPK.
 
 Rosegarden appears to allow the sending of the midi signal from each 
 track to separate outputs. But I cant get them to work. so I am 
 obviously doing something wrong. I should make it clear, finally, that I 
 do not have a problem with the external midi controllers themselves in 
 that it is perfectly possible for me to connect them both up to two 
 instances of VMPK and have /them/ both play with two separate voices at 
 the same time (in other words, my second diagram, minus Roasegarden). 
 The problem is between Rosegarden and VMPK.
 
 I am guessing this has got something to do with seeting channels for the 
 two tracks inside the midi, but I haven’t a clue how to do that. Or, 
 indeed, if it is actually possible, even in principle, to achieve the 
 above in Rosegarden.
 
 Please help, if you can.


Right click on the Rosegarden channel label and set both of your tracks to CH1
but to the two different destinations. Make sure you have both recognised in
