| vlt | Hello. I have one broken key on my stage piano. It seems to always send 100% volume and I have no time to fix the issue on the hardware side. What tool can I use to take the piano’s MIDI out and alter the data in a way that this one note will always have either a fixed volume or better the volume of the previously played note? | 14:37 |
|---|---|---|
| vlt | (in realtime) | 14:37 |
| OvenWerks | qmidiroute | 14:38 |
| vlt | OvenWerks: Thanks, I’ll have a look at that. | 14:38 |
| OvenWerks | You can set up a filter or two that allows everything else but that note through and another that set the velocity on that note. | 14:39 |
| OvenWerks | So three filters 1) everything below, 2) everything above and 3) that note only | 14:40 |
| vlt | (Aah, it’s “velocity“, not “volume”) :-D | 14:43 |
| vlt | So, that would be the setup for the fixed output velocity, right? | 14:43 |
| OvenWerks | Ya, you could set the whole thing for fixed, but you could just set the one key sort of medium. | 14:43 |
| vlt | That shoud be sufficient for now. Just curious: Can I plug in something like a Python function that will use the last seen velocity value for the affected note? | 14:45 |
| OvenWerks | That sounds like a great solution, but I don't know how :) | 14:45 |
| OvenWerks | I would have better luck in c/c++ | 14:46 |
| OvenWerks | python is not realtime, but for midi that may not matter. | 14:46 |
| vlt | I’m quite sure it’s realtimy enough for MIDI data, yes. | 14:47 |
| * OvenWerks is not familiar with ALSA code just jack. | 14:48 | |
| vlt | qmidiroute works well for the fixed velocity solution. Thanks! | 14:56 |
| * vlt has to get used to the slight delay | 14:56 | |
| vlt | Is there a way to reduce the MIDI latency? | 14:56 |
| vlt | Depends that in any way on the jack buffer size for audio data? | 14:57 |
| OvenWerks | I don't know. Once it becomes jack midi, it is the same as audio, but the alsa end is different. The buffer is 16 byte, not the same as the audio. | 14:58 |
| vlt | A new problem: My setup is piano (set to “local off”) out => qmidiroute => piano in. Works for “note” events but now my sustain pedal is ignored. It appears in the event log as “Ch 1, Ctrl 64, Val x”. I have a qmidiroute rule of type controller with output controller and no changed values. | 15:12 |
| vlt | Any idea what might be missing? | 15:12 |
| OvenWerks | I don't know. It does look like it should just work... but I don't have any MIDI equipment set up to play with. | 15:15 |
| * vlt fires up a second instance of qmidiroute to watch the events coming out of the first one. | 15:16 | |
| OvenWerks | The ones I normally use, don't have a pedal (drum pads, PSS 480) | 15:17 |
| OvenWerks | I don't have room for even the DX7 these days | 15:17 |
| vlt | Works now o_O | 15:18 |
| vlt | Hmmm. Don’t know what convinced it. | 15:19 |
| OvenWerks | I got to know qmidiroute as a way to split my drum pads so I could use different synths for each drum | 15:23 |

| WingFin | Hi, is there any compiling help here at this time of the day? | 17:34 |
| PulseAsio | dunno | 17:35 |
| OvenWerks | compiling? Maybe, though I don't know anyone who is compiling guru | 17:36 |
| WingFin | I want to make an Icecat from this source http://git.savannah.gnu.org/cgit/gnuzilla.git/snapshot/gnuzilla-52.1.0.tar.gz | 17:36 |
| OvenWerks | and the problem is? | 17:36 |
| WingFin | I there is not enough hand-holding for my knowledge | 17:36 |
| OvenWerks | is there an INSTALL file in the base directory? | 17:37 |
| WingFin | I cannot work out directories srcdir and objdir | 17:38 |
| WingFin | no INSTALL | 17:38 |
| OvenWerks | normally, three commands: | 17:38 |
| OvenWerks | Make configure | 17:38 |
| OvenWerks | make | 17:38 |
| OvenWerks | make install | 17:39 |
| OvenWerks | After make configure look at any errors and install required *-dev packages. | 17:39 |
| WingFin | yes, i understand that but this is more involved or maybe not | 17:39 |
| OvenWerks | Well thats about my level :) | 17:40 |
| WingFin | It shouldnt be too involved all the work seems to be done, | 17:41 |
| WingFin | Where is a good hands on compiling guide? | 17:42 |
| WingFin | for studiobuntu | 17:42 |
| OvenWerks | did you try ./makeicecat | 17:43 |
| WingFin | yes | 17:43 |
| OvenWerks | So I would guess you got errors? | 17:43 |
| WingFin | [sudo] password for elaine: sudo: ./makeicecat: command not found elaine@X230-T:~/Downloads/icecat$ | 17:45 |
| WingFin | maybe studio has not the needed libraries | 17:45 |
| OvenWerks | did you try it without the sudo? | 17:45 |
| OvenWerks | it is saying it did not find the file that is plainly there | 17:46 |
| OvenWerks | ls -l makeicecat gives what? | 17:46 |
| OvenWerks | (what is the permission string?) | 17:46 |
| WingFin | :~/Downloads/icecat$ ./makeicecat bash: ./makeicecat: Permission denied | 17:47 |
| WingFin | ~/Downloads/icecat$ ls -l makeicecat -rw-rw-r-- 1 elaine elaine 28756 May 5 2017 makeicecat | 17:48 |
| OvenWerks | chmode +x makeicecat | 17:48 |
| WingFin | ~/Downloads/icecat$ chmode +x makeicecat No command 'chmode' found, did you mean: Command 'chmod' from package 'coreutils' (main) chmode: command not found | 17:49 |
| OvenWerks | sorry chmod +x makeicecat | 17:49 |
| OvenWerks | (don't know where the extra e came from) | 17:49 |
| WingFin | :~/Downloads/icecat$ chmod +x makeicecat elaine@X230-T:~/Downloads/icecat$ it took | 17:50 |
| WingFin | so now ./ ? | 17:50 |
| OvenWerks | so try ./makeicecat again | 17:50 |
| WingFin | thankyou wow its working | 17:51 |
| WingFin | so just give it chmod authority | 17:51 |
| OvenWerks | The file wasn't set to allow execution, now it is. | 17:51 |
| WingFin | nice it is downloading the rest of the source | 17:52 |
| OvenWerks | ya, all of firefox :P | 17:53 |
| WingFin | thanks a lot!! | 17:53 |
| OvenWerks | no problem | 17:53 |
| WingFin | Hi, I need to add (gtk+-unix-print-3.0) to be found in my repository, but Ubuntu is not included here: https://pkgs.org/download/pkgconfig(gtk+-unix-print-3.0) Does UbuntuStudio have a normal source for such a puppy? | 22:40 |
| WingFin | I'll try to find a .deb | 22:42 |
| WingFin | I have to put this on hold for a few hours | 22:45 |
