A few questions regarding SFZ format, i.e. LinuxSampler and its support on Zynthian.
- I seems LinuxSampler supports SFZ instruments using FLAC format (through libsndfile library), right? If so, as LinuxSampler streams sample files as you play, I guess there’s some overhead compared to playing a SFZ using WAV files, due to decompressing dozens of FLAC streams on-the-fly. Correct? Any idea of the impact on polyphony (I have a RPi4)?
- Now about adding SFZ instruments to Zynthian:
- You can upload instruments using webconf, but for linuxsampler the interface only allows .gig and .zip (and other compressed formats) extension. Does this mean I should zip the SFZ file and all its audio file dependencies in a zip file, then upload the zip file? If so, what should the file structure inside the zip be? Everything at the root? How does this copy into the Zynthian: does everything go into a per-instrument directory? (I don’t want all the samples of all SFZ files mixed up in the same place). I tried to upload a zipped SFZ this way, but the main one I want to import is a 4GB piano, so the Zynthian was still stuck hours later I launched the upload and I eventually gave up
- Is there an alternate method: I can imagine putting the SFZ+sample files on a USB stick, then copying from the stick to the SD card with command line using SSH, but it’s a bit of a pain. Would that work at least?
- Is there yet another more user-friendly method? Would be nice to have a “file explorer” to navigate inside the Zynthian but I couldn’t find any way to do this.
Thanks in advance
