csDrummer 20080926

by Schlagg

csDrummer: Record a drum session in a virtual studio Copyright (C) 2008 Schlagg csDrummer allows you to achieve same result as if you were recording a drum session in a real studio. Instruments are triggered by MIDI messages either real-time or from MIDI file. An audio stream formed for each instrument is routed to its own channel, thereby simulating a microphone record. Software uses sound morphing technology for interpolation between two layers of an instrument sampled with maximum and minimum hit force. This brings a much more realistic effect than switching between a number of separate layers. Each hit passes through humanizing filters which alter its force, morphing and time offset. Theese filters give an effect of a real human playing a drum set. All documentation, source code and distributives can be found at http://code.google.com/p/csdrummer

Re: [LAU] Rosegarden crashes - anything obvious to look for?

Batch-processing through JAMIN?

by Ken Restivo

I am helping to (hopefully) produce a CD of one of the bands I'm in. The recording and mixing has been done on ProTools on a Mac, but it's been suggested that we "get it mastered". Before we spend money we don't have on some mastering house, I'd like to take the WAV files of the scratch mixes we have, feed them through Jamin, and see if the result is satisfactory. I'm certain I could write this, but I don't want to if it's already been done. So, is there a command line tool out there that will take a WAV file as an input, put JACK into freeswheeling mode, then jack_connect to a running Jamin instance's stereo in and out ports, open a WAV file for capturing the output, feed the input WAV file in to JAMIN and at the same time start capturing samples for the output WAV file, and thus basically feed this through JAMIN as fast as it can and give me a finished WAV file that's been "mastered"? I tried scripting this with jack_capture and mplayer, but there are two problems. The first problem is the mplayer starts playing before I can connect its output ports to JAMIN's input ports. The second problem is that jack_capture starts capturing long before mplayer is started, and then doesn't stop until long after mplayer is done, which gives me a bunch of silence at the beginning and end of the capture file, which is annoying and has to be cut out manually in some kind of audio editor later on. -ken

I have tried MuseScore but right now it is a bit unstable for everyday use, IMHO. It is a great project though, and I'm greatly looking forward to a stable 1.0 release. ~Nathan R.

Bug in Aconnectgui?

by Crypto

Hi, there is a GUI tool named Aconnectgui. I use it for connecting MIDI ports to and between MIDI applications that connect to the ALSA sound system and MIDI ports. It seems there is a bug: Step 1: Run Aconnectgui. Step 2: Run fluidsynth -a alsa --midi-channels=48 This will start up fluidsynth and fluidsynth will create three virtual MIDI port (instances) that will show up in the Aconnectgui tool. Step 3: enter "quit" in fluidsynth. The MIDI IN ports of fluidsynth are closed and deleted in Aconnectgui. Step 4: Run fluidsynth again as in step 2. BUG: Aconnectgui will only display the first of the three MIDI IN ports of fluidsynth. You can now close Aconnectgui and rerun it. It will display three MIDI IN connections for fluidsynth again, which is correct. Is this truely a bug or am I missing out something? I think it is rather annoying when testing MIDI stuff a lot. Aconnectgui ought to update the connections in a more reliable way. Thanks for any help and regards, Crypto.

If your fw-card has three ports, there are two possibilities: a) pass hw:X with X in {0,1,2} in the jackd-commandline b) plug the fw-cable into all of the ports and test with each one (with jackd on hw:0)... > i haven t been able to compile gscanbus yet (probs with GTK) Too bad.

Re: [LAU] NtEd 1.2.1

by Nathan Hale

Indeed, NtEd has come a long way, very quickly! Once the author adds just a few more features, it will be ready for prime-time as a typesetter for concert music and and even lead sheets! As professional musician and music masters student, I'm really looking forward to Linux having a stable and fully WYSIWYG score editor. ~Nathan R.

You started the thread on the lau-mailinglist, yet you keep answering only to me in private. Unless you did that on purpose (for example if we are to discuss very personal things) this is considered semi-bad because a) others might be able to help where I can't and b) others might have the same problem later on and see only your question in the archives but not the solution...
