Currently I have some trouble to diagnose the MIDI note problem.
@Dithered42, are you able to share a MIDI file which creates the stuck note issue?
@jofemodo, am I correct in assuming “jack-smf-player.c” is the program referred to as Zynthian MIDI player? I wish to try reproducing the issue on desktop computer.
As I recall, any MIDI file I tried had the stuck initial note/chord problem. It didn’t seem to be some strange edge condition caused by a unique sequence. The initial note or possibly chord of any sequence I tried just stuck on.
Again though, I was unable to repro that condition with a MIDI controller. I tried several times including REMOVE ALL and starting again with a fresh launch of String Machine assuming the first notes from the controller would stick. They didn’t.
Re-installed the stringer now. Everything is great except the presets from 1 to 12 don’t show their names; only 13 to 19 are named. Presets 1 to 12 are still under names like “Program 1, Program 2”, and so on. And I really like now the chorus rates - 1.0 to 9.0 and 0.1 to 0.9. Awesome range there is!
There is an advice if I may. How about a phaser FX with the range between 0.1 and 0.9 in the end of an FX chain? Then the stringer will be totally authentic:) It’s now definitely possible to add it from the Zynth FXs, but… Having it’s own phaser makes the stringer THE whole thing 
As I recall, any MIDI file I tried had the stuck initial note/chord problem.
I’ll let it fly, as I’m not to reproduce it in any situation tried, and I tested the voice manager as much I can, it seems solid as much as I can tell.

This is not expected, this name scheme is supposed to be gone by the current version.
If I were to take a wild guess, it’s possibly a vestige which remains from the older one and creates a conflict. Maybe a copy these have found their way into user presets? Someone who knows about these can maybe explain it.

I have made a phaser FX already with intent to add it to the string synth.
It will be for a future release, in the meantime it can be used as a plugin by itself.
YES-YES-YESSSSS! 
Highly likely, the steps I mentioned install string-machine into /zynthian/zynthain-my-plugins/ the official script installs into /zynthian/zynthian-plugins. Jalv is reading both manifests.
I didn’t think the official install of String Machine had been rolled out yet. String Machine is only installed in zynthian-my-plugins on my machine.
My presets only show 001-019 with the associated names. No “Program XX” listed.
We’ve all been running:
Finally. Had to delete all previous installs and re-install again. Now everything shows great. Thanks for y’all’s help! 
Some happy chords (stringer, noise mak3r for bass, and pd grids for drums) 
I hadn’t run the official script yet. Deleted everything, ran the install. Works great.
Hi
I tried to apply the recipe but I get following message after “update_zynthian.sh”:
“…
Checking for ‘lvtk-plugin-1’ : not found
The configuration failed
(complete log in /home/pi/zynthian-sw/plugins/ams-lv2/build/config.log)
The project was not configured: run “waf configure” first!
…”
Then “$ZYNTHIAN_RECIPE_DIR/install_string-machine.sh” result in some other failure message and string machine is not in LV2 list in webconf.
I understand that there is some components missing in my case most probably.
Do you have any clue ?
Development news
Hi, I found a very interesting source of information in the “ARP Omni 2480 service manual”, which has many explanations of the circuits. This synth has some common design with the Solina, being apparently a hybrid of subsynth and strings.
I’ve checked out the oscillator section and compared to mine. The Omni has an extra control known as “Enhance” which permits to bias a clipper which is part of a transformer of square to sawtooth wave, and adds some harmonic content.
I think to add this control in the String machine, and I made a formula which is implemented as experiment, but I’m not yet entirely satisfied.
Also, I have thankfully identified a dumb bug in the Osc which is after I added PWM, and inadvertently the oscillator is a 10% duty pulse instead of a 50% square.
I have to fix this before a release happens, but it’ll also need readjusting the presets which have their sound altered after this change.
The exact message is necessary to diagnose the issues. The other issue is for amsynth which is likely unrelates.
Hi @Mr Dham!
I made some fixes to the string-machine install script. Try updating zynthian and run install script again.
Regards,
It works now ! Thank you.
You’re are right, I should have given the complete message.
What does it sound like down in the bass?
Did you do the mp3 externally…?
The sound sample was made straight away after I got it working.
That’s why it sounds a bit rough (I set no attack, decay, reverb…) but it already has a typical string machine sound. I like it
I made the wav with the Zynthian sound recorder and compressed it into mp3 externally for easier uploading to the site.
Later on I played it and could make some more subtle sound.
I’ll try to provide another sample by end of the week and focus on bass…
Another sample as promised:
A rather nice TV link !!!
