I am really glad you are doing this. I don’t fully understand all of what you are describing but I would like to share some requests from a “user perspective.” I apologize if I am restating some things you have described.
(1) Multi-channel and Stereo Recordings. I have a multi-channel DAC and a stereo DAC. I have become interested in comparing multichannel and stereo versions of the same recording. I have purchased some NativeDSD downloads in both formats and loaded them into my Roon library.
Roon seems to either ignore one of the versions or use an identical tag for both versions. Because my labelling (which specifies MC or 2Ch), it is difficult to tell which is which. I would like to easily view both versions, side by side, rather than to try to investigate what happened to the missing one or which one is the one I am looking for. This “experiment” has become unnecessarily difficult.
I would also like to do a search of multichannel recordings only (i.e., without stereo recordings being included in the search) and vice versa. This would be helpful for when I am listening to music with my multichannel system as well as with my stereo system (located in a different area of my home).
(2) Composer, Conductor, Orchestra/band searches. I would also like to be able to search by composer, conductor, or orchestra/band in the same manner we are now able to search by artist and album. This ability would also be attractive for other types of music as well.
(3) Album labeling. I would also like to have the option of viewing entire albums as they were published (i.e., with all of the tracks) and viewing a particular piece (e.g., a 4 part symphony) without the other tracks on the album. This would be also very useful when I want to hear a particular symphony and would like to select among a number of conductors or orchestras/bands.
An alternative might be to have a composition listing, which would be for all of the parts of selected works my collection. For instance, I could select “Bruckner’s Symphony No. 7” and see all of my recordings of that symphony (including recordings with only some of the parts – although some notation about this would be helpful), without the other pieces that might have appeared on the same album.
Thanks again for doing this. It looks like you have put a lot of effort into this. I am very grateful.
