Large Libraries not opening

When importing multiple MIDI Files and creating a larger library (say 50 tracks+), Synfire is unable to open the libray once saved or if does open it - it struggles to do so (time to import is in the minutes/freezes program while doing so).

Apart from analysing less tracks in one import session- is there a way around this? I'd much prefer to run Synfire overnight analysing hundreds of tracks and then be in a position to edit/process the next day. Possible?

Synfire libraries currently have a soft size limit at around 20 MB or so. That's because they need to load into memory as a whole. We will eventually turn that format into a folder structure with individual phrase pool files, which will eliminate the limit.

By coincidence, this topic also came up in another thread today. As said there, batch import is most useful for large numbers of small files with simple content, e.g. drum patterns, bass runs, brass stabs. If you have full arrangements you want to harvest for phrases, you'll need to manually select unique and interesting regions anyway. So why wait hours for figure recognition, if you can import as static pitches in a second and immediately grab the phrases with Command-E and refine them as needed?

"soft size limit of 20 MB" ? Really? Todays home computers have 8GB+ of RAM

It's not about RAM. There's some processing power required to unpack the object structures while loading. IIRC, loading a library also occupies around ten times its file size in memory. Serializing large objects with a lot of crosslinks and backlinks is more demanding than reading audio files.

That said, the actual limit is the number of pools, phrases and parameters in it, not so much its file size.
