I guess I'm lucky this time around. I'll be playing Rosegarden, and for reasons unknown and at unpredictable intervals, MIDI playback will speed up and slow down. Awesome. This is exactly the kind of thing that prompted the initial bitch message that ultimately dragged me into this whole mess 12 years ago. I was lamenting that it seemed sad that a sequencer couldn't get something as fundamental and basic as MIDI timing right, when my old 286 used to handle this just fine. Apparently we still can't get MIDI timing right. Man is that depressing, and I don't have a clue what to do about it. Linux timing sources apparently SUCK. -- D.

If so, I'd go that route. Whatever solution is the easiest/most-practical to implement combined with fulfilling my requirements (being able to start rosegarden recording by sending it a MIDI message or a combination of MIDI messages) would be fine with me. However, I should mention that I have since found a work-around. It's rather ugly, but it appears to work. I send a UNIX STOP signal to rosegarden, then click the GUI "record" button, then sit down at my MIDI keyboard and hit a pedal/key combination that tells my filter program to send rosegarden a CONT (continue) signal (which brings rosegarden out of stopped state so that it starts recording), and I immediately start playing. When I'm finished I hit a pedal/key combination that results in rosegarden receiving a real-time STOP message - and it stops recording. > > > However, this > > is coming from a naive view - I'm a programmer, but I know very > > little about the source code.) > >- If it's not possible, is there some workaround?

Have you tried it? It > might actually work! I did try it, but I don't think I plugged in the right parameters for the required MIDI::ALSA::output call. rosegarden did not respond. I used Kmidimon to view what was being sent and although it showed a song position pointer message, the data value for the message was bizarre - a large negative number. In the code I plugged in all 0s, expecting to send a song pos value of 0. But either I'm sending the wrong parameters (documentation for sending this type of event seems to be nonexistent) or there's a bug in the library I'm using. I'll get back to you if I succeed in actually sending a 0 value.

If so, I'd go that route. IIUC we only inspect MappedEvent subtypes at a few places: * Where they come in or out in AlsaDriver * Where we insert them (or not), which you recently changed. We only do that when we're already recording. Alsa was experimenting with some sort of RECORD signal, but I'm not sure the current status of it.

Re: [Rosegarden-user] How to cause rosegarden to record via a MIDI signal
Hello Michael, Somehow my name got dragged into this -- and I bet it had to do more with MIDI than it did with brittle code. LOL Anyhow, RG if set to be slave, listens to MMC commands, but doesn't respond to all of them. In theory we could allow it to listen to MMC code 8. That would press the record button only. The user would need to hit play either in RG or have their device emit MMC code 2 (play). Unfortunately, I'm not in a position to try this out immediately. Sincerely, Julie S. "D.

What you'd want is the ability to arm the record button separately from the play button, like an old tape recorder. Not sure why it doesn't do that already. In principle, doing what you want should be something like punch in/punch out recording. In practice, that still isn't reliable after 13 years, and it's a dubious feature. This code is what Julie Swango would call brittle. I hate messing with it. It's like playing that old Milton Bradley game where you use the tweezers to take out the little plastic bones, and if you touch the sides, you get shocked. (It's not supposed to work like that?

[Rosegarden-user] How to cause rosegarden to record via a MIDI signal
Hi Rosegarden team. I've written a perl program [1] that filters MIDI messages and - when certain message combinations are received - modifies the MIDI data, or creates a completely different MIDI message, or etc before sending data on to other MIDI recipients such as rosegarden. One of the things I'd like to do is to send a MIDI message that will tell rosegarden to start recording (so that I can start the recording process at the MIDI keyboard instead of having to hit record on the RG interface and then meander over to my keyboard and start playing). The real-time start message (i.e., system real-time start - http://www.midi.org/techspecs/midimessages.php) looks like a good candidate, since when rosegarden receives it it actually does start - but it starts playing, not recording. I can't (AFAIK) set rosegarden up in a "stopped/record-on" state, such that when it receives this start signal, it starts recording. I remember asking about this, or a similar issue, in the past (I think it was this year), but I don't think there was a clear resolution. (I just grepped for 'record' in the subject line of all the messages from this list on my local system and did not find a subject relevant to this issue.) So, I guess I have a few questions: - Is it possible for rosegarden to have its record function triggered by a MIDI event that it receives instead of hitting the GUI record button? And if it is possible, of course, how is it done? - If it is not possible, how hard would it be to add this feature to the code? (Since it does start playing when it receives a START message, it seems to me it should not be hard to modify it to allow recording instead of playing when it receives START. However, this is coming from a naive view - I'm a programmer, but I know very little about the source code.) - If it's not possible, is there some workaround? (For example, what if I hit 'record' to start rosegarden recording, then send it a song-position pointer message for position 0 to force rosegarden to reset to position 0 and continue recording from there?) Thanks! Jim [1] This program still in development, but I hope to release it on github soon. -- LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
