There was a request to try to model a berimbau in MSF, so I tried to do it in this video. I didn't get it perfect, but I hope the basics and small tricks I show in this video will allow you to tune the sound to your liking. You can also take this concept and make your own strange hybrid instruments. I hope you find this useful.
In retrospect I should have cut the bass a little more, adjusted the combfilter and made it a bit more buzzy, but hopefully it doesn't sound too bad.

OK. I have a backlog of devices I haven't finished right now. The growl bass, the Timpani, the synth strings, the snare drum. I though I was doing pretty well, but I'm starting to realize that I have a bunch of devices I need to finish.

Thx. I'm in the ballpark now following the tutorial. Digging around later for better approximations of gourd timbre.
Biggest stumbling block at the moment is the rock as separate strike type (or at least lack of a new strike). The most common pattern I hear for berimbau (it must have a name, but I don't know what it is) look like this on a piano roll where C is the open string, so the first and last notes are the stick hitting the open string, and the second and third to last are the stick hitting the string shortened by the stone. The second is the tricky bit since it is where the stone engages the already vibrating string.
For the sake of ease of programming parts, it seems to me that this should be handled via legato which is why I've extended the first note to overlap with the second. Digging through MSF now to work out details like a very quick (but not quite zeero) legato slide upon overlapping notes so when that second note comes, it will alter the pitch of the first already resonating.
I'm wondering, though. It's not just a sudden pitch change on that second note where the stone engages, but rather a bit of extra buzz, etc. Is there some way to trigger something other than the pitch slide only on legato (beginning of a note that overlaps a previous note?)

Well done, Chandler!
Besides some kind of tiny FR: wouldn't it be a thing to have some kind of exciter module? I mean ... Chandlers techniques works great and he is ALWAYS using the drum synth thing as an exciter. I can imagine a faster and maybe a bit more physical-modell-oriented way with haveing some kind of easier and faster to set up exciter module. Just a tiny though, nothing urgent and not even mandatory, after all.
Omg! I am so looking forward to your devices, nice!Chandlerhimself wrote: Tue Jul 28, 2020 3:34 am OK. I have a backlog of devices I haven't finished right now.

On that note: As a general rule, I tend to shy away from plugs that artificially limit how extreme you can be with the settings, and tend to think that if you're always parked at one extreme of what it will let you do, then what you really need is to be able to go beyond that.Tagirijus wrote: Fri Jul 31, 2020 9:25 am

As far as using the drum module as an exciter, it has a minimum time of 10ms when setting up the sweep. I suppose there are kludgey ways around that like setting up custom curve that dives faster, then putting inline envelope after to shorten, etc... but the simple fact alone that it's always being used at one extreme of the settings it allows tells me it's not optimized for the task or dialing in subtle variations.
I'd also just be interested to hear what else might make for an ideal exciter for different types of sounds (strings vs drums, etc) and why.

Perhaps this week I'll do a video on exciters and how you can use them to change the sound.
