Hmm, the cyclic mode is supposed to be round robin ... what is wrong with it in your view?

And yes I could make an 8 note one, will put it on the wish list, it should not be too much work :-)

Maybe there is a bug then yes, I'll look into it.

Yes there is a bug .. the mode input never gets processed Shocked

Actually there were a couple more MIDI bugs, you can tell I don't use MIDI that often myself .. so thanks for pointing it out to me.

I've been playing around with MIDI now for a good many hours, and at least the cyclic mode should work now and internal MIDI transport seems okay too.

I've also implemented a new multi-note-in module with 1 - 8 channels (selectable), the old one is still there too for compatibility reasons. It is based on the new code with a fixed maximum number of notes of four - so both modules should have the same bugs now ...

A new release is availble: 2020-05-30

See https://bluehell.nl/wren/#changes for the changes
See https://bluehell.nl/wren/#top for the downolads

I did not make a new source code release for this yet.

Nice to see new updates Bluehell. One thing I noticed was the problem when I had the ASIO driver "FLASIO" installed. When it was installed there were no visible audio devices in the audio settings. Sometimes this driver is handy. When i uninstaled it everything was fine. Oh, by the way. Maybe you consider a module similar to the ensoniq machines for transwaves (asr-10) or hyperwaves (ts-12) synthesis. That would be killer feature.

Blue Hell · Posted: Fri Jun 05, 2020 5:09 pm Post subject:

Hmm .. I googled a bit for the stuff you mentioned .. and I have no idea why FLASIO .. I asume that to be the FL Studio ASIO driver ... would not work.

Edit: Was there anything in the log file? (wren.log in the same folder as the wren.exe file, note though that the log is being rewritten on every start of Wren)

Re. the wave table sequencing thingies you mentioned .. I might find it interesting to look into that a bit better .. but was wondering .. maybe the WavePlayer module could be used for such stuff . as it has a position input .. so theoretically ... I guess I'll have to wonder a bit more about this Laughing

Apologize for not clarifying. That was asio driver from fl studio. Sometimes i'm using it because this driver didn't take all asio exclusively for one app. Waveplayer module is nice for granular stuff i think and this is no problem, there are plenty plugins for this type of synthesis. Ensoniq is more "wavesequencing" thing. Uploading wren log and pieces of manual about waveform manipulations.

Thanks boaone.

I'll look at them PNG files.

Re. Wren not seeing any devices .. it looks like the PortAudio DLL is present and then when it is initialized it will crash (with a division by zero error .. odd) .. I'm affraid I can not currently do much (will need a new license for microsoft stuff, and can not test as I do not have (nor want :p) FL Studio), but will think about it more.

boaone · Posted: Sat Jun 06, 2020 8:00 am Post subject:

Yes I think i know what you mean Wink

. I'm using only the driver of FLStudio for another DAWS because this driver didn't take entire control of ASIO protocol and i can run more software at once.

Blue Hell · Posted: Fri Jun 19, 2020 10:02 am Post subject:

I have made a debugging setup to try to zoom in on the driver issues .. it adds loads of PortAudio debug info to the wren.log file.

https://bluehell.nl/wren/modules.2020.5.30.debug.zip

Please copy the contents to a unique directory to not mess up any original stuff, run wren_debug.exe and when issues seen please attach the file wren.log here to a reply.

Hope this will help to zoom in a bit on the problems.

One idea for useful option. Recording module or option at mixer on the right side with buffer of about max 10 minutes (variable) or something like that. When one have something useful at buffer then button or hotkey to save that to files. Maybe with flac encoder at the end and normalization. I had to test that "flasio" again and will send log.

Blue Hell · Posted: Tue Jun 23, 2020 3:52 pm Post subject:

ok, will think about your ideas - seems useful to me and I've put it on the wish list.

then .. I might ask you to another test after the previous request .. working on a 64 bit Wren version right now, wondering if that would have the same issues .. but will need to do a little more testing on it myself first.

to my surprise I was able to use ReaRoute on the 64 bit version .. so .. just maybe .. that will also solve some interfacing issues too.

Made a new thread for FL ASIO and Wren, for FL issues .. please go there : http://electro-music.com/forum/topic-71936.html

Blue Hell · Posted: Wed Jun 24, 2020 1:17 pm Post subject:

I've made a new release, and although there are some changes in .. for instance how wave files are being read by modules and supported audio formats, the main reasons are:

1) I've made a 64 bit version

2) I've made recompiles for the PortAudio DLL to address an issue with the FL Studio ASIO driver. Both the 32 and the 64 bit version will co-exist with FL Studio using FL Studio ASIO .. on my test sytem. And both versions can not use the FL Studio ASIO driver for sound I/O themselves - what does work on my system is the RME ASIO driver.

For details see : https://bluehell.nl/wren/#changes

For downloads see : https://bluehell.nl/wren/#top

Note 1: there are now two versions to download a 32 and a 64 bit version. For both the executable file is called wren.exe ... so you could keep a 32 and a 64 bit version in two separate directories. For a 32 bit Windows version the 64 bit Wren will not work.

Note 2: For wren 32 I've renamed the PortAudio DLL into portaudio-r32.dll (and the old portaudio.dll is no longer used).

Note 3: For Wren 64 I've added portaudio-r64.dll, espeak-64.dll and libfftw3-64.dll

I did not make a fresh source code release at this time.

Blue Hell · Posted: Sat Jul 18, 2020 1:55 pm Post subject:

And another release .. 2020.7.18.0 - with recent source code too.

For details on changes see : https://bluehell.nl/wren/#changes
For downloads use : https://bluehell.nl/wren/#top [and select the 64 or the 32 bit image there, whatever you need and or prefer - the 64 bit version is way faster]

Main changes are :

- sped up the 64 bit version a bit more by removing floating point (un-de-)normalization for it (64 bit version specific).
- Added audio chaching, such that when a wave is used in multiple modules it will only ne loaded once, and it speeds up patching a bit too for longer waves being loaded. This applies to all wave player like modules.
- Made a recorder module, and removed the old recording functionality. The recorder will always hold the latest xx minutes of audio, where xx can be selected. Then when you like it you can hit write to write the buffer to disk.
- Some bug fixes (custom wire colors work now, rate conversion properly reflected in wire colors too now, some annoyances and some oversights, stuff ...).
- added AM inputs to lots of modules.
- better tempo control for the BPM related modules.
- Added a folder selection dialog to select default folders for the various file types used.
- A new stereo narrower module, and a stereo panner.
- Some internal changes to allow for tighter integration between editor and sound generator at some later stage.
- It is now possible to select <nothing> for the in or output device, should solve some issues where the input could not be opened by PortAudio.

There were some bugs in the previuous one (2020.7.18.0) ... sorry for that Embarassed

... I think they may be fixed in the current one (2020.7.20.0).

Recorder is very nice module. But for some reason some fm input in "modosc" module not working anymore.

Blue Hell · Posted: Thu Jul 23, 2020 4:38 am Post subject:

Checking ... right .. I made the fm input a knob instead of an input .. so it does not 'exist' ... hmm my consistency checker should have found that .. time to fix that one too!

This is not a big problem considering there are hundreds of modules and complexity. Maybe that's not the right thread. One thing that prompts me to go back to g1 or g2 every time is a little "midi" problem. Wren loses notes every few moments. It's excellent for learning and tinkering and without midi from outside its working ok. But with some external sequencer and some arp or so its a big problem. Latency is ok now and overall speed much improved.

Blue Hell · Posted: Thu Jul 23, 2020 6:06 am Post subject:

Right .. found 65 more such issues .. over 8 modules ... fixing them now.

Blue Hell · Posted: Thu Jul 23, 2020 6:44 am Post subject:

Ok, all fixed .. according to current state of checking code Laughing

Midi .. dropped notes .. hmm .. will look at it.

Blue Hell · Posted: Thu Jul 23, 2020 8:28 am Post subject:

Not really hearing notes dropping here .. at a rate of about 8 notes / second .. but the timing is a bit sloppy here ... just as the midi clock timing is .. there is some room for improvement there .. not using midi much myself ... anyway .. treating note ons & offs and real time messages in a more direct way ... will fiddle with it a bit more.

Blue Hell · Posted: Thu Jul 23, 2020 9:53 am Post subject:

Right .. timing depends on the buffer size set for audio .. hmm .. need to think about that.

But .. with a buffer size of 256 instead of 2048 it is a lot batter.

Made a small recording with the following setup.

G2 side :

Wren side:

Posted Image, might have been reduced in size. Click Image to view fullscreen.

I started the G2 at 4.07 Hz for the LfoC2 module, then 8.14, 12.2, 24.4 and ending at 3.05 I think ... is what the omage shows anyway ..

I did not use the G2 clock module, as it acts weird ...

Anyway .. timing wise, is this better / worse than what you are getting?

oh, and the delay and reverb stuff in wren ... got annoyed a bit with the dry sounds .. so added some color, on the recording it is all off.

Made a new release [2020.7.23.0] for fixing the inputs / parameters issues found.

Also changed the MIDI handling a bit for note on/off handling, should be a bit faster now.

And I just realized ... I should add a MIDI queue, as there is a risk still that when MIDI processing is not fast enough in the synth that the message(s) being processed will be overwritten with new incoming MIDI .. yuck .. anyway . .something to look into for a next release.

Also noticed, that for large audio frames (say, 2048 sample sets) MIDI gets jittery, not sure how I should fix that though. On my system with a frame block size of 256 it seems ok now.
