Sound creation for your music project
Challenge your self, or your students to go out in the nature, or in house. Just find a sound to make (real sax, oboe, and so on), and take this in use with rosegarden. to achieve this you can take in use Swami (aptitude install swami) there are something you have to be aware of, after you have installed swami, at this moment the swami do not add a menu entry in multimedia, this I hope some day will be fixed, but until that day you have to start swami in console, or pres ALT + F2 and type swami.
Swami have a nice GUI and looks like this:
Swami at this moment are under devlopment, so the version you have to use is abit old, but it works. The swami projekt can you take a look at here: http://swami.resonance.org/trac
Configuring Swami to use Jack
To make this work at the same time you have audacity, rosegarden runing, you have to configure swami to use jack as a sound connector:
After that you have to start jackd you have to manualy connect FluidSynth so you can hear what been played.
So now you are ready to start create your own sound to use with you musik project.
How to make a sound
How to make a sound? Here you have to use audacity to record something, for example scream, word, or some real instruments, when you have cleaned up your new sound, you can export this as and WAV file, and import this into swami. In swami you can connect that sound to a program change number, and at last export your new sound as an SF2 file, and use fluidsynth-DSSI-plugin in rosegarden and take in use your brand new sound. Isn't that cool?
So lets go into this step by step.
1. File, create new 2. Right click on untitled, and choose Properties. (Rename it to your liking) 3. Click on the "+", and right click under Samples, and choose load sample (choose the wav files you want to use for your instrument) 4. Click on the "+" behind Samples, and User, there you see your wav file. In our case, there are two files, named L and R (Hint: file names are truncated to 10 characters) 5. Then click on Instrument, so it gets highlighted, then click right and choose New Instrument 6. Click on the "+" behind Instrument, and right click on New item, and choose properties and change name to your liking. 7. Then it's time to select the samples to be used for our new instrument: Mark them within Samples/User by holding down the control key while clicking. Afterwards, you can insert those samples at Instruments/Your Instrument by means of the Paste function in the context menu (right click). Your Samples have been assigned to the instrument name you made. (Hint: This works like a link; whenever you change sample properties, this will also take effect in your instrument.)
And just repeat the cyclus for each sound, and when you are finished, you just save it. And it's time to use it.
Sample Tuning for Advanced Users
When creating a chromatic instrument from a set of samples that cover different pitch ranges (bass, mids, trebles), further actions need to be done to make sure you get a continues sound.
You will need information about what note is played in each sample. This reference note can be set either in sample properties, or you can simply move the white marker to the corresponding key. You can hear the effect instantly, when you click on the keyboard: The original pitch is played when you hit the reference note. From here it is bent up or down, depending on the distance you move right or left.
When you have set all reference notes for you samples, you should hear notes of the same pitch nonregarding what sample you select!
For continuous sounds (like organ, flute, strings), your samples can never be as long as the longest note that might be played when using your soundfont. Therefor it is necessary to define a loop range that is repeated over and over when the musician will keep a key pressed. Again, you can move two markers to find a section of constant amplitude - try to find zero crossings in the sample to prevent disturbing clicks.
