programming a m-audio axiom 25
Hello.
Recently I bought a m-audio axiom 25 USB keyboard. I've tried it out with ableton live and adobe audition and so far I like it. However, I'm still a bit puzzled how I can tune the keyboard? I'd like to be able to specify specific frequencies for each individual key, so I can play pieces in alternative tuning systems (like just intonation). http://www.kylegann.com/wtp.html Does anyone know how this can be accomplished most easily? Thanks in advance for any suggestions, Niek |

Thanks in advance for any suggestions, Niek Niek, I don't know your state of knowledge, so permit me to point out something very basic. From the product description, the Axiom25 is a "MIDI controller." This means that the keyboard itself does not generate any tones. It merely sends signals of switch closure via the MIDI protocol to the computer. The computer must run a "synth" program or plugin that interprets the MIDI signals. A program is a standalone software that creates the tones. A plugin is an addition to a program, and it does the same thing. Each program has different provisions for tuning. Some offer a selection of scales, ie., tempered or nontempered. Now an expert on synths can step up! Bob Morein (310) 237-6511 Hi Bob. Thanks for pointing that out. I had kind of figured this out from the manual of the m-audio axiom 25 (the way the keyboard only generates midi control messages and not actual tones). But I am indeed kind of new to the world of midi keyboards and computers. I used to play piano when I was younger and I love computers, so I figured it would be interesting to see if I can learn some of the things you can do with a midisequencer. I'm fairly knowledgeable about computers, but my experience with audio software is rather limited (except for adjusting the volume and bitrate of mp3s or basic manipulation of wavs/mp3s in soundforge). I'm also interested in experimenting with rhythms and one of the things I've noticed is that most programs tend to break things up in intervals that are the inverse of a power of 2 or 3 (so, 1/2,1/4,1/8,1/16,1/32,... or 1/3, 1/9, 1/27, 1/81,..), where the midinotes snap magnetically to these gridlines. Like suppose I work with the following method: I divide the interval of time between t=0s and t=1s into units of equal length, where beats occur at the start of each segment. So I can divide an interval in 2 and have a beat at 0 seconds and at 0.5 seconds. Or I can divide the interval up in 4 segments and have a beat at 0 seconds, 0.25 seconds, 0.50 seconds and 0.75 seconds. This way, with the magnetic grid lines, it's easy to create 2 beats per second, or 4 beats per second or 8 beats per second, etc.. Using the triplet function that is available in live and audition, you can easily create 3 beats per second, or 9 beats per second or 27 beats per second, etc.. However, it seems that it's not possible to setup the grid in such a way that I can have 5 beats per second (or 25 beats per second) in an easy fashion employing the magnetic grid lines (so a beat at t=0s, t=0.2s, t=0.4s, t=0.6s and t=0.8s). Likewise 7 beats per second is also difficult (a beat at t=0/7s, t=1/7s, t=2/7s, ..., t=6/7s). If anyone knows of a midisequencer that features more possibilities to configure the grid, so you can work not just with 2-fold or 3-fold divisions, but also 5-fold or 7-fold (or higher prime numbers) divisions, I'd be very interested in hearing about it. It's interesting to investigate interference and resonance between various rhythms. Like how 2 beats per second is in sync with 4 beats per second, exactly identical in the way any particular tone, like 220 Hz, is in sync with a tone that is one octave higher (440 Hz). For instance, you already obtain an interesting rhythm if you have a triplet in a snare drum and doublet in a base drum (and adding regular hi-hat hits at 1/6th of a second fits in nicely): Here you can see how I create it in audition (slowed from 120 bpm to 100 bpm for a slower pace): http://www.ibbu.nl/~nsprakel/audition.jpg This is what it sounds like when I play it back in a loop: http://www.ibbu.nl/~nsprakel/drum.mp3 |
