Please, disable the reverb in the clavinet SFZ. All SFZ instruments should be “dry” by default. Reverb should be added later.

Regarding the Steel Drum SFZ, what is the modwidth parameter? I can’t perceive any difference when changing it.

From the script it should widen the stereo image.

jSteelDrum.sfz

main


      
          
          <control>
          label_cc1=Mod:width
          set_hdcc1=0.5
          default_path=flac/
          
          <master>
          
          // Mod wheel controls stereo depth
          
          width_oncc1=100
          width_curvecc1=99
          
          // more dynamics
          // exp = 3
          //amp_velcurve_0=.0001
          //amp_velcurve_16=.0020
          //amp_velcurve_32=.0160
          //amp_velcurve_48=.0540
          //amp_velcurve_64=.1280
          //amp_velcurve_80=.2500

This would of course only work if

the samples are in stereo
width_onccN is implemented in sfizz while the sfizz opcode reference says it don’t.

Installing Terkelsen’s Marimba I found 2 presets.
I suggest to add some notes about it in description.

Anyway, good job!

Will do.

As @hannesmenzel says, it’s stereo width. I only tested with Sforzando, when I first created it years ago. I’ll double-check on Sfizz/windows and Sfizz/zynth. Thanks for mentioning it. The samples are stereo.

Thanks for the feedback. The -xfade one has velocity crossfades and is the recommended one.

Presets without velocity xfades are to reduce the number of voices being used. On jRhodes, it makes a big difference – when I have a lot of other plugins running I get xruns. But when running just jRhodes, I much prefer the smooth transitions between velocity layers. So, IMHO it’s important to have both.

With steel drum, we rarely play lots of notes at once like we do on piano, so xfade should be the default and either no need for xfade, or make it a keyswitch. I’ll put that on my to-do list. I’ll be sure to update the package info in Webconf accordingly.

Is there a way to document presets other than in the package info?

Not currently.

New package: SoulBrass (PR submitted)

Soul Brass section sfz for live keyboard use on Zynthian

Each note plays up to four instruments:

trombone
tenor sax
alto sax
trumpet

Controls

Each instrument has CC control for

volume
octave shift
pan

By default, all instruments play at the same volume, with no octave shift. Trombone and trumpet are centered, saxes are panned left and right 45 degrees.

REQUIRED PACKAGES

This repo includes no audio samples. It uses samples from these packages:

Zynthian Factory SFZ’s
VSCO2

Until the package is added, you can install it way:

cd /zynthian/zynthian-my-data/soundfonts/sfz
git clone https://github.com/jlearman/zynthian-soul-brass
