I have an export problem in Hydrogen.
When i export an single pattern as a wav file , the exported file is shorter than the pattern was in hydrogen!
this means: when i import my exported loop in a sequencer , i realize that the exported track is shorter than in the hydrogen pattern. Therefore the loops are not seamless.
Why does hydrogen produces shorter wav files?
I cant use hydrogen for production, its sad.

I think I had the same problem as you describe. An easy solution is to create a song from e.g. four bars of a single pattern, and export this song. You can then easily crop this wav file into a single loop.

I know that but its very uncomfortable!
On linux and win they dont have this problem!
but thanx to your reply;
Would it be so hard for the develeopers to kill this ugly bug?

Hi,

this bug exists on all platforms. We don't have a solution for this at the moment.

i should its almost impossible to get rid of this bug. coz no thing is perfect tho, the system is no exception.

svn rev 1466 improve the h2 export functions.
also it solve the sample length problem.
of course the export samplerate settings must be the same than the samplerate you use in your composite application.

Thanks wolke!!
Works well here, although the problem described here - H2 cropping off the last part of a pattern - isn't solved.
What would be nice though if H2 would remember your last settings as the default setting. Now it defaults to 44.100 Hz/ 16bit.

hiho,
fast... 30 minuts to create a new binary :).
ok, did you test the new rubberband feature under osx.
you have to install the rubberband-cli you find here.
http://www.breakfastquay.com/rubberband/
i am interested if it works under osx.
just now i create a h2-rubberband demo video. maybe tomorrow its ready.

i generally solved an other length problem.
this was the problem that the timing from your exports wasn't right. this happens because hardware dependent samplerate settings. now h2 use fixed rates to export.

i found the problem now. think i can fix it.

now this end of export gap problem is fixed.
checkout rev 1467.
greetings wolke

up to rev 1472 i have add some improvements. (format templates)

rev 1472 also solve some bugs. imo this is a good point to test all export functions.

here a summary of changes i made:
1. use fixed hardware independent samplerates
2. allow more export formats (wav, aiff, flac and ogg)
3. allow format dependent settings for samplerate and sample depth
4. give some format templates
5. fix two general bugs
* end of export gap
* exact export output sample length.

Hey, nice work wolke!

I think you solved this export issue. The exported wav file loops perfectly now! Great job.

I also installed rubberband and will check out how that works too under macosx.

i have no mac. general under linux h2 found the rubberband cli in environment.
if you have an other path to your rubberband cli you can edit the path to your binary into the preferences dialog first tab.

e.g
/home/yourhome/bin/rubberband

if hydrogen found the rb cli in env. you can find some combo boxes into sample-editor which can control the rubberband cli.

what ever i have no luck with kdenlive to create an nice video. since my last apt-get update kdenlive is broken. ahhhhhrg :(.
so i only make a small record to show how rubberband works.

into the video you can see where you find the configuration and also how i cut an drum sample to a 8 beats long surf beat.
after i will fit this to the current running bpm. sample length is in dependences from bpm. h2 now can calculate the right length using rubberband. so the sample fit to the pattern.
also you can see how you can make transient settings.

at least you see what happens if you enable a small rubber button on the left side from bpm widget. after activating h2 recalculate automatically all samples which use rubberband every time you change bpm.

joostjodel and wolke, great news you both made.

joostjodel , do you have an build for Leo osx?
The last one you made had crashed......


Yuhuuuuuuu!

@tungee Sorry, I am on Snow Leopard and I've set everything up for this system, so the resulting binary does not work for Leopard (and frankly I am too lazy to reinstall everything..)

But I'll update the wiki with more detailed instructions how to build Hydrogen on the mac os platform. There are quite a number of steps involved but it isn't difficult anymore - esp. since mauser is on osx too..:).

Here's the link to wiki page
