Ok, so, I'm not happy with the end result, but I need to stop fiddling with it. I like some of the individual parts, but as a whole feels a bit soulless. The mix isn't very good either, that doesn't help :clown:

I think the main failing was that I was originally trying to force a vision for the sound design onto OB-Xf, rather than letting it actually dictate the direction and play to its strengths, so the end result is a mix of things thrown together that I don't feel nearly as cohesive as they should be.

It was a good playground for some different stuff though - side-chained compression, reverb, bus compression (but probably not used very well), and some native DAW LFO automation of the synth options.

Keen for next month, I have some composition ideas I want to play with, and this time let the synth actually drive the sounds rather than ham-fisting shit together.

Does Ob-xf have Program Change to quickly switch between banks and presets if this is possible already ?

Post

Yes, steps to make it happen:

1. Inside your user patches folder (Documents/Surge Synth Team/OB-Xf/Patches) create a new folder called MIDI Programs
2. Place your wanted patches inside of it. Prefix them with 000, 001, 002 etc to specify the order in which you want them (it's going to be natural/alphabetically sorted)
3. Program Change should work next time you instantiate OB-Xf (or, if you've already had an instance running, refresh the patch browser)

This won't work with VST3 as it stands, only CLAP and AU, if I remember correctly. Same deal as in Surge XT.

Third time entering OSC! I had some plugins disabled but I don't know if the script detects that. The harmonic plugins are just OB-Xf I renamed

This is a song about my first migraine, which happened 2 weeks ago. It started with an extreme visual distortion called a "Scintillating Scotoma".

This song is 1-instance-per-sound. I did not use the piano roll; the song just kind of plays itself. The main "trumpet" melody is triggered by impulses generated from OB-XF's noise + LFOs. The LFO rates are adjusted over time, along with some other things, to create the melody. All other sounds are triggered/started when the melody hits a certain note. I applied light automation, and used a crapton of external modulation with MSEG-1.

I have to say, the KVR OSC has provided a truly wonderful community, and I am grateful for it.
The music created by the community members is so good, and I take my hat off to them.
The fact that this community remains free of any disruptive behavior is a reflection of the management by the administration.
Once again, thank you so much to the organizers and all the members for providing such a wonderful opportunity.

OB-Xf is pretty great! The prolific baconpaul, EvilDragon, and crew have made another great sounding, stable, and efficient synth. Being OB-X sort of thing always ends up being a bit limiting, but I made something anyway:

To echo @z.prime, very nice implementation of the OB. Kudos to the Surge Synth Team.

Here's my entry, a little move away from my usual genre - you got to try now and then?
