SF2 and SFZ soundfont limitations for deep notes
I'm a hobby rock / reggae bass player trying to write scores with drums, bass and sometimes melody instruments. As my musical & composition & score writing abilities are quite limited I need the acoustic feedback to know what I'm doing and also to play along.
With the new & shiny MS 2.1 I decided to take a new try with soundfonts to get more realistic sounds for (E-)Bass. But after downloading & trying to install several sound fonts I've reached a certain level of frustration. It took me a while to find out that lots of soundfonts don't play deep notes (typically below C3 ... E3), even those targeted for bass. I guess there are technological limitations of the fonts or the synthesizer. Still, a warning message when assigning or playing would be really helpful.
I've attached a simple score with drums and bass giving me playback problems with most sf2 and sfz fonts.
Before starting to nag in detail: I really like MuseScore. The fact that even I can produce scores with drums, bass, melody instrument is proof enought for the excellent usability of MS. A big thank you for your work during the last years!
Still, I think the usability of MuseScore with respect to SF2 and SFZ sound fonts could be enhanced, probably without too much effort:
- There is no way to distinguish which instrument is contained in which soundfont file in the mixer. If you have loaded several soundfont files with lots of instruments with unspecific names, selection of instruments is really hard
- A separator between Fluid and Zerberus instruments in the mixer menu would be nice
The support of Zerberus & SFZ fonts seems especially bad to me, I would say at the verge of unusability for the average user. At least for me, it took quite some time & several trial & error runs until I found out:
- You cannot install SFZ fonts with a double-click (at least an error message is thrown)
- You have to manually copy SFZ-file and samples to the "secret" directory /sounds with admin rights
- There is no option to select a different directory (and SFZ sample files can be in the GB range ...) or at least to find out the required install directory from the GUI.
- There are no warnings if anything goes wrong
- There is no way to upload *.sfz files to this forum
I installed the SFZ sound font from http://www.turtlesounds.net/Ibanez_roadstarII_series_fingered.zip but notes below E3 are muted. Is this a limitation of the sound font or of the synthesizer? Can I see the range limitation from the SFZ control file? It consists of sections like the snippet below for all twelve notes.
