And what about decay? Does the EMX allow midi control of A,S,R but not via the front panel knobs? Just trying to figure out how you did this, thanks.

I'm just using software VCA signal to control LEVEL of each channel. That signal is sent at 10hz (fast enough for now i think) to the LEVEL (#10), like each other modulator signal to each CC to simulate VCAs or LFOs.

I choosed to remove DECAY as you can do that in the ATTACK part (but i'm perhaps wrong and will readd it one day).

The Emx allow only to use (has i know) LFO routed to AMP with the last waveform to simulate an ATTACK but only an attack... and u used your only one LFO

.

I can explain more if you want.

No, I understand. The VCA lives in your code and sets the EMX level for the part 10 times per second. Very cool! And your attack is really attack + decay since you can program each point, so I get it too. I'll try again later with my novation keyboard (I forgot, but it has a second midi input to my PC).

Yes. U can adjust the rate in the config.properties file, but I don't know how low you can go (overload of midi traffic ?).

Hope it'll work

(The third midi question dialog could be bypassed due to bug, choose an input that wouldn't be used).

Problem with OS X greater 10.4.8 is, that it's JVM does not support direct midi i/o any longer.
Fortunately there are several thirdparty MIDI SPIs available, that fill this gap and allow access to Apple's CoreMidi.

Thanks Kossi.

I have downloaded and looked trough api, and test exemples. Seems not hard to use. But the problem is I don't have mac to test it so i'm blocked for now. But i'll not forget it.

Second problem for mac is that several people reports that the jar don't work on mac os x due to :

Code: Select all

java.lang.UnsupportedClassVersionError: Bad version number in .class file

.

So for now, I know it work fine on windows.
Program launch well on linux, but can't test cause midi interface not detected correctly on my system (?).
For Macosx, i would like to know if anyone here manager to launch it, and make it work with midi (<=10.4.8 or stg).

Hope i'll find that bug soon, but my priority is to have feedback of the windows version first (not a lot for now), for linux, then mac. But due to the demand on mac i have to find solution soon

See u.

Hi,
I would love to help. I have a PC and a Mac, although I don't have an electribe!

It might help you though if I point out that OSX is based on linux.

I assume you compiled against 1.6? In most OS X 10.5.x installations 1.5 is still standard. 1.6 was distributed via software update but the user has to change default JVM via the app: /Applications/Utilities/Java/Java Preferences.App.

alternatively you may include this in your launch-shellscript:

Code: Select all

JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
export JAVA_HOME

/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java -mx128m -Djava.library.path=$base -cp $CP $clazz

Unfortunetaly i have no access in the moment to my MBP to verify this.

Best regards, Kossi

You can use 1.6 but set the compiler compatibility flag to 1.5 as a quick test.

wax78 · Post by **wax78** » Wed May 13, 2009 4:41 pm

Kossi:
Yes it's compiled for >=1.6.

I add a third launch script for macos as your recommand me Kossi (but it's -Xmx128M no?typo).

Yatmandu.

Yes but the problem is somepart of my code need to be rewritted for java 1.5, cause i'm using some new functionnalty of 1.6. I'already tried, but ill do another attempt =)

Thanks my friends.

Ok, here's a version compiled with 1.5 compliance for mac users.

http://renaud.warnotte.be/Brols/macosx.rar

Hope it won't stop on the Bad class number exception

Starts up here with OS X 10.5.7 and Java SE6 (64bit), no luck with J2SE 5.0 (both 32 and 64 bit).
Just opened the jar with the standard jarlauncher-app built in in OS X with Java set to Java SE6.
go_macosx.sh also launched the app after setting executable bit to the .sh.
What did not work, is that the app sees the connected midi devices. Just shows the Sun internal one's.

Ok, but the program launch, wasn't case before.

But you're certainly facing the MIDI bug of macosx (short resume).

I'll try to write a version that use mmj instead of standard api. Perhaps it'll project us one step further

I wounder when someone who can programing, make emx1 editor, like this for em1 http://www.midiweb.de/index.htm ?
