oxefmsynth's Issues

Port Oxe FM Synth to GPLv3-ed VST3

It seems that Steinberg has released the VST3 SDK under the GPLv3 license (on a repo here on Github). At the same time, it seems that VST2 support is coming to an end.

It's possible to build both VST2 and VST3 versions of plugins. I suggest that at the very least, users can choose to build a VST3 version. This would require some modifications to the code, of course, since it seems that the APIs are different (I am no VST expert but I can't find AudioEffectX in VST3, for example).

Black window instead of gui

It is not possible to use gui as I can only see a black window.
plugin built from sources (AUR)
Arch Linux x86_64, kernel 4.4.5-1-ARCH, gcc 5.3.0, mesa 11.1.2-1, nvidia 361.28-4

oxe linux vst crashes Ardour 4.4

Hi...The latest version 1.3.4 crashes Ardour 4.4.621+r14315 in Linux Mint 17.3 64bit. I downloaded the plugin tar, then put the so files in ~/.vst. Ardour sees the plugin but inserting it into a track all by itself crashes Ardour. Running Ardour from terminal, here's the error displayed:

actually writing state to /home/mo/Numero Uno/Numero Uno.tmp renaming state to /home/mo/Numero Uno/Numero Uno.ardour /usr/lib/x86_64-linux-gnu/ardour4/ardour-4.4.621+r14315: symbol lookup error: /home/mo/.vst/oxe/oxevst64.so: undefined symbol: glXQueryExtension

Please let me know if you need any further information to reproduce this issue. Thanks!

osx

@oxesoft me dá uma ideia de como rodar num osx? só com VM mesmo? preciso de uma luz, hahaha, C definitivamente não é a minha praia... até tentei fazer o build dentro de um docker, mas por motivos óbvios que pensei agora isso não faz sentido nenhum hahaha.

Plogue Bidule does not recognize oxefmsynth on MacBook Pro

Dear programmer, Greetings. The demos posted on YouTube for this program are simply amazing. I have downloaded oxefmsynth.vst to my Apple MacBook Pro, which is equipped with OS X 10.11.6 El Capitan operating system. I am using Plogue Bidule version 0.9752 as the host program. I have had no problem using Bidule as a host for other softsynths. Bidule does not recognize oxefmsynth.vst, even though it is located in the same folder as are the other softsynths. (~Library/Audio/Plug-Ins/VST). I am new to the Apple operating system. My skills at computer programming are insufficient to solve this problem by myself. Any suggestions or assistance would be greatly appreciated. Thank you. 3261Lee

Double clicking (to reset) doesn't work on delay and reverb level knobs

Double clicking (to reset) doesn't work on delay and reverb level knobs (has no effect).
(IMO it should put the value to 0 when double clicked.)

Is the reverb mono?

I was a bit surprised to notice that the reverb effect doesn't seem to produce any stereo image.

Removing from renoise causes a crash

I'm using the latest 64 bit binary in renoise (linux) and I have found that oxefmsynth can crash renoise.

Load the synth, right click on it in the instrument list, choose delete. At this point renoise crashes. It doesn't seem to do it every time but is fairly consistent .

Saving Presets

Hi, first thank you for making this great VST/Plug in, love the sounds.

I'm wondering if there is a way to save new or customized sounds as presets?
I tried and it saved the entire preset library

OS: Windows 7
DAW: FL Studio 12

Oxe FM Synth doesn't react on `all notes off` and `all sound off` midi messages

Please make pitch bend range configurable

I really love this synth but it's missing an essential (IMO) feature: configurable pitch bend range (up to 24 semitones).

Can you please add it? :)
It would just require one more knob (there is still GUI space below the Oxe logo).

Btw, does the synth respond to the pitch bend range RPN?

(Both would be desirable but the latter would be sufficient as a workaround for now (easier to implement because it doesn't require changes to the GUI)).

Possible LV2 version?

Have you considered creating an LV2 version of Oxe FM Synth, along the VST one?

Sometimes clipping happens when reverb volume is on maximum

When I put the reverb volume on maximum and play certain notes with certain patches (e.g. program 48: PercOrgan) the sound is clipping.
Maybe it makes sense to have a master volume knob or a simple internal compressor like sylenth? (or a tube waveshaper as soft knee limiter)

Can't set up Mingw for OxeFMSynth + scaling issues?

SOLVED: [Oxe Synth is really small, and is hard to use, especially for a beginner. I wish, if there were a drop-down option, or maybe for now, a bigger GUI. Is it possible to do that?]

And would there be a guide on how to build for Windows? I think that I have mingw - which comes preinstalled with Git Bash, or Railsinstaller. What next? Because maybe, I could figure it for myself?

Aliasing and quantization distotion

I've noticed two problems with the sound quality, even when using the "HQ" option.

• Aliasing distortion for high pitched notes (best heard with Saw waveforms)

• Quantization distortion for quiet notes (best heard with quiet Sine wavesforms with long decay)

Here's a video demonstrating this (you'll need to listen loudly to be able to hear that, but the spectrogram shows the problems very cleanly):

Black GUI on Linux

Hi,

I managed to build the latest version of OXE on Linux and the VST works inside recent Bitwig soundwise.
The GUI though is black inside the host as well as in the standalone version.

Do I put a skin folder next to the vst plugin into my vst path to use the skin inside my host
like I should with the standalone version?

I'm on Linux Xubuntu 15.10 XFCE 4.12.

Rework user interface

There's a room for improvement.

Some possible improvements:

• Switch programs via a list or arrows, add a dialog with folders and categories to load/save banks/programs.
• Draw envelope curves
• Modulation matrix: connect values with lines to form circuit (FM8 style)
• Add a midi keyboard (yes, very please)
• Make UI less ugly (not a UX issue, but still)

Look at Helm and Dexed (both are free software) to see how a good UI can look like.

Git tag for 1.3.1 (and following releases)

Could you tag each new release in Git?

This would make it easier to package oxefmsynth for Linux distribution packages built from source for a specific release.

How do I name preset?

I swear the only thing I haven't figured out is how to enter letters into the GUI to name my preset, something really wrong if the GUI can't handle something like this easy.

Microtonality support

See MIDI Tuning Standard and Scala file format.

Fix: Reverb wrapping distortion caused by integer overflow in calculation

This has been an outstanding issue for a while, but after looking at the output from a wave recording in a sound editor, the shape of a sine wave with reverb turned on and playing them at the loudest volume made it obvious.

Been trying to fix it on my own in the code but there seems to be some funny quirks with the coefficients in the calculation in synth/reverb.cpp (even after trying to simply clip to the INT_MAX/INT_MIN of possible culprits in the equations). In any case, here's a WAV recording of the symptoms in its obvious form (you can see it wrap the sine waveform in an oscilloscope): https://dl.dropboxusercontent.com/u/1287967/oxefmsynth-reverbwrappingdistiort.mp3

EDIT: on further investigation, it may well also be an issue with synthesizer.cpp unctions for SumStereoMono() and SumMonoStereo() since they sum integers without taking into account of any possible overflow wrapping?

Makefile.vstlinux is missing -lGL in LIBS

I got "undefined symbol: glDrawArrays" when I tried the new version 1.3.4, which I fixed by adding"-lGL" to LIBS on line 57 in Makefile.vstlinux.

Where can I find vstsdk2.4?

I'm trying to compile from clone of this repository on Fedora 32. Converter/demo/standalone are working, but VST build gives me this:
Makefile.vstlinux:18: *** Please set the VSTSDK_PATH environment variable to the vstsdk2.4 path. Stop.
make: *** [Makefile:27: all] Error 2

Links to vstsdk2.4 on steinberg site are all broken. Can someone add it to this repo?

Linux LFO doesn't work

Using oxevst64.so (from oxevst133.zip)

When I edit a LFO parameter while playing a note I can hear the changes to the sound.
However when a new note is played the LFO no longer has any effect on the sound.

Hope I made myself clear :-)

Other waveforms?

I wonder if it'd be possible to allow using other waveforms apart from sine waves?
I think It'd really kick up it's possibilities.

I have no idea if that's feasible with the synth's internal design.

Is it possible to have more than 2 preset banks?

I found a few banks on the web, I'm wondering how to use them.

Great synth, btw!

Crash in Qtractor 0.7.1

Hi. I tried to launch oxe in qtractor 0.7.1, but it crashes. To reproduce, add midi track with oxe plugin, then in the oxe configuration dialog window click "edit" (see screenshot http://wstaw.org/m/2015/11/25/53_1.jpeg)

Here is Backtrace:

Preset saving\loading bugs in Ardour

Hi. I am using Ardour 4.4 on Linux with oxe-fm-synth v1.3.4.
There are two issues:

1. When previously saved Ardour session is loaded - oxe does not restore previously loaded preset - it always loads first avaliable preset - Glassy Piano. (ardour preset selector says prevoius preset is loaded, but really it is not - you can hear that it sounds like Glassy Piano, and see all the knobs are wrong)
   Expected result: oxe should load prevoiusly saved preset.
2. When i choose some preset, move some knobs and save the session - this preset gets overwritten by current state of knobs (for this instance of oxe-synth plugin). If i will ever want to return to the original preset - i will have to delete this plugin instance, create another one and select wanted preset. This is not how other plugins handle presets. Preset should never be implicitly overwritten (even for single plugin instance) - there is "save" button for this. Also current knobs state can be saved by user explicitly as new preset. Also current sate should be saved when session is saved, but should not overwrite any named preset.
