2SYNts- regular guitar to poly synth

Hola technologists!
I had a long thread back at SynthMaker about this mono pitch detector that Leif Oddson built.
I thought I would start one here.
I have tinkered and puzzled and then some over this thing.
NuBeat really helped with Ruby stuff at one time, and Tulamide also to make the MIDI mono.
I used Bootsy's fast RMS, which seems my best amplitude detector.

It needs a hex guitar(a Roland GK3 pickup), which is one with individual pickups for each string.
Also all strings need to be a C string(note 48, .711mm 028 gauge).
The pickup is broken out and run into an interface with 6 inputs.
Then all you have to do is set the on/off gate- using the Gain.

Here is the schematic(open source), VSTfx .dll and the UI resources->

full version 2SYN midi and synth 205->

It is 0 crossing based detection,
which relies heavily on a feedback loop to focus the band.

EDIT-> July 2020
I have now made this work for regular electric guitar turning it into synth, which works better than MIDI,
but it does push out the zippered MIDI
here's the project->
the .fsm will only open in the FS Alpha sorry, but u could back it up and open it later if u haven't yet joined the Slack group.
Here's a screen->

It works quite well and I would really appreciate it if any of you guitar players would like to try it
-- let me know here how it goes if you'd like to

NOTE: all 2SYN builds require 44.1khz samplerate to process the pitch accurately

Hope it's interesting!-

Remembers me of the early 90's, when a band member one day used his guitar to play my synth. I thought "Wow, we really live in the future" :lol:

I wanted to have a peek at the schematic, but with 3.0.6 I only get a dozen of "Type not found" error messages and then a crash to the desktop. What is the minimum Flowstone version for it to work?

I get the same with 3.08.1

Nix, any chance you could link to the original .OSM version? Then we can change the extension to .FSM in our own versions and it'll probably open. I guess this was saved with the new Beta 3.09 because I've had this happen before recently...

Sorry, it's 309b1
This is very much a current project, and the old .osm doesn't perform well.
I hadn't implemented the cut feedback at that stage.

hmm. I have stopped running 3.0.4 again, it seems one install is better.

Maybe come back to it when u upgrade

Hello again!
I have updated the link in the original post with the full point version 1.1.
After some issues(crashing) with the 309b2, this version is built with 3081,
so maybe most can have a peek at it.
This approaches perfection now, and I may call it finished.
Does anyone want to use the existing GUI as a wireframe, and make it look nummy?
I'll be back with some audio demos in the next couple of days.

Velocity is twitchy as anything, it could be improved.

Rock on, Nick

edit- all you need to set is the 'Gain' multiplier, to get the on/off gates correct

Here are the graphical resources->
edit- these are down now, I want to try and go pro with this as I have made a poly guitar synth from a regular/ts guitar

ver 1.2 available in the first post!
It's still getting better

OK- I have smashed this a bit now.
The download is in the first post, ver 1.3.
Audio demos to follow.
I got it to register the 22nd fret on my strat(while letting B open ring out over it), which was very wishy-washy until now.
Now it switches to last played note in the detector, which seems better than a string root.
Also, when in bend mode, there is only soundcard latency and RMS window time as the delay before note on.

Heya Rex, I just read over the thread, and if you are interested to see where this project has started until current- here is the original zx 0 crossing schematic by Oddson .osm->
