Re: [gentoo-user] can genkernel install files with different names?
you are just wrongly assuming that they are mutually exclusive... seriously, one could have kernels named, without versions, as: vmlinuz vmlinuz-older vmlinuz-older2 . . . vmlinuz-olderN this way, new kernel installation, and rotation, will be decoupled from the boot loader's configs, effectively removing any housekeeping for the boot loader. rgrds, cm. ‐‐‐ Original Message ‐‐‐ On Monday, October 21, 2019 7:07 PM, Wols Lists wrote: > > You just want a nasty recovery job if the update screws up ... > > Seriously, I always just add new kernels as the new default option, > precisely so as I can go back to a working one if things go wrogn ... > > Cheers, > Wol

There have been a relatively large number of OMR projects falling in and out of obscurity, forked, taken over, mixed with closed source and then die. I was looking for an OMR package in portage to scan PDF sheets of music and then split different voice parts out into separate midi files - but if a single application will do the full workflow then I would be more than happy. > A quick search led me to audiveris.

There are also a number of other applications some of them for Linux - but I haven't found one yet in portage (TBH I wouldn't know its name off- hand). >From what I read here Rosegarden will not perform OMR itself, but will import various file formats: https://www.rosegardenmusic.com/doc/en/file-other.html -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Re: [gentoo-user] OCR for music (OMR)
I vaguely remember using some windows based program when archiving old music. The community in question had maps full of paper scores and making them digital would have made it much more compact and versatile. However even back then I remember manually writing lilypond files. I did use Linux at that time but wasn't aware of any OMR tools. Eventually I stopped visiting and the project fell out of favor due to the immense manual labour. Literally hundreds of sheet music ranging from single page meant for the artists up to the combined score for the conductor. A quick search led me to audiveris. I have no experience but it might do what you want. It has the option to export to MusicXML. I tried to use Rosegarden to read a MusicXML which "worked". It did get the notes right, but alternated with trebble and bass lines, being a somewhat monophonic end result.

I'll check Rosegarden again in case it can perform OMR. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

That's why I have Chromium, as well and LO and qtwebengine, set to use my SSD for PORTAGE_TMPDIR on this laptop, which is limited to 8GB. MAKEOPTS is also constricted for Chromium. As a result, the packages build more quickly with minimal impact on using the system. -- Neil Bothwick Top Oxymorons Number 3: Working vacation pgpSZT2Se7d0N.pgp Description: OpenPGP digital signature

Rosegarden is a midi editor, and might have some scanning ability. Lilypond is a music publishing program and can generate midi output. If you transcribed your music into either of those programs (Rosegarden would be best) you can generate midi, but that's work you clearly would rather avoid ... Cheers, Wol
