core audio: system overload.

After two days, I am at a standstill. I will strip out a few more things from the system, and limit processing to a few instrument tracks without running any effects which is not very much fun but at least until I can figure out next steps. Perhaps it is time to step up to a 2.0GHz+ x 2 G5 PowerPC machine or even an Intel box running only Logic and relegate this G4 to running pithy applications like Photoshop and InDesign and Mail and Safari.
I am still trying to figure out an overall system scheme that includes a server that is always on that has our music on it (so we can access it anywhere including the Xbox to play it through our audio system) but also picture files, documents, etc. etc. and then something that is screaming fast that includes multiple drives for effects files and sample files for Logic and I thought again of the G3 sitting in the basement that could play media server once configured with a bigger drive that then backs up to say its own USB 2.0 or Firewire drive on a schedule (this could even have all our documents on it too and we could access mounting via AFP) then (and this is wishful thinking) a new G5 or Mac Pro running Logic with either multiple internal SATA drives backed up to its own Firewire or internal drives setup as RAID-1 mirroring within Disk Utility but the point being that machine and its backup would only be for audio files while the G3 server would serve up everything else. Julian would still have his G4 iMac and this G4 would be used for Photoshop work. As long as this is wishful thinking, I could try selling this G4 which would possibly net me a few hundred clams and then I would get a G4 iBook (1.0 or 1.25Ghz why not?) to use as a webbook to sit on the couch and surf the web and do email for which I would set up a wi-fi router hidden somewhere in the living room or maybe just in the media closet once it is all assembled and then also when plugged into a monitor to run Photoshop and InDesign and such and it would be reading/writing to the (possibly G3) server as stated would be backed up by an external drive.
Hmm. Jeff says I have reached nerdvana. He also said there are hundreds of networking options it is just a matter of finding which one suits your needs. My initial thought is I think this would work. And yes I totally realize this entire post was completely pointless to anyone besides myself more like me instead of talking typing to myself which I suppose pretty much describes this entire blog so there you have it system possibilities and overloads and all.

logic.

ps – apparently running a stereo channel with the space designer reverb set to the 'old plate' parameter and the grand piano sample is already maxing out my dual CPUs and causing a bit of breaking up in the signal so must switch to a mono channel.

imperfections.

I used to struggle with the idea of perfection. I am an über-perfectionist and was always proud of this fact. Everything needed to be perfect or it was worthless. Everyone needed to be perfect or in them I would hold no interest. I set impossibly high expectations for everything in which I surrounded myself. It was an odd predicament for which I set myself up given the fact I knew, well, I was not perfect. But I could not accept compromises in any form.
Until I listened to an old vinyl recording I picked up I do not know where and do not know when of Wilhelm Backhaus performing three of L.v.Beethoven's most powerful sonatas for piano. I do not recall which piece he was performing when I noticed through the headphones I was wearing that his piano was slightly out of tune. And his phrasing was slightly off. Granted, ever so slightly. But off. Imperfect. But it was brilliant. It was perfect.
And that was it. The spell was broken.
Since that moment some evening years ago, I have become aware of many instances where imperfection is perfect and necessary and I am reminded of this as I work through tuning the Bechstein. The entire basis of the modern method for tuning a piano relies on imperfection. Mathematically a piano cannot be tuned perfectly. Well it can, but only to one key (well, actually several but I will try to keep this thought simple without totally getting into the mechanics of acoustic theory). There must be a compromise in order to play the twelve minor and twelve major keys we have so cunningly devised.
Along these lines Plutarch wrote ~
"Music, to create harmony, must investigate discord."
I have numerous texts on the subject of tuning and what we call temperament including a perfectly old text published in 1946 simply titled Piano Tuning and Allied Arts. It is as fascinating as the stars. How the art of tuning a piano (and yes, it truly is an art) is as I tend to find the most appealing a merging of science and art. It is incredibly mathematical in its design, but what lies at the heart of being able to carry out is the human element of hearing the waves of sound the beats and pulses of two notes set against each other and the timings and from those pulses to determine the correct temperament (most recognizable in the octave, unison and fifth) caused by the waves in the defective pair alternating recurring periods when the condensations and rarefactions antagonize one another. In other words – or word, as it is called in physics – interference. It requires a clear understanding of harmony, the natural and artificial phenomena of musical tones and how they relate to each other through intervals and those specific relations. It is mesmerizing.
The term temperament means quite literally "a system of compromises in the tuning of pianofortes." Compromises. Imperfections. Both necessary in order to achieve a balance – that being able to play in all twelve major and minor keys (the pianist David Helfgott's professor told him quite assuredly that "it is all a question of balance"). There are two principal temperaments in our twelve-step musical intonation – mean-tone and equal. Mean-tone temperament was used primarily before 1700 and intervals like the fifth and literally every step of a scale were tuned perfectly. This sounds wonderful, but physics complicates the matter (bother logarithms) and music written in one key could not be transposed to another without certain intervals sounding atrocious (due to the complications of a vibrating string's overtones). It was around 1691 that Andreas Werckmeister theorized a series of tunings where enharmonic notes had the same pitch in such that the same note was used as both (for example E♭ and D♯), thereby bringing the pianoforte into the form of a circle. This refers to the fact that the notes or keys may be arranged in a circle of fifths (anyone who has taken even an elementary music theory course will recognize this term) and it is possible to modulate from one key to another unrestrictedly. It was quite brilliant and formed the basis of the modern tuning system.
But how it works is simple and complex – the fifth is tuned perfect .... then flattened slightly. The complication of course is in how much. In a true equal-tempered scale, all half-steps are tuned equally and thus no two fifths will beat exactly alike because the lower the fifth, the slower it should beat while those in the treble are meant to beat faster, for if all fifths were tuned perfect we would end up being unable to transpose our music (the physics is quite complex and I will refrain from elaborating). There are a number of different tests the tuner performs while setting the temperament to check this flattening of fifths (listening to other intervals – the perfect thirds, the major sixths and so on).
I have known people who have replaced their pianos with electronic keyboards for ease of use – the electronic version never needs to be tuned (or – with the aid of a sequencer – can be tuned to any number of different tuning systems). Electronic music can also be quantized (in software like ProTools or Logic, for example) which is simply a method of aligning notes to a mathematical grid so-to-speak so that each note is perfectly in time – rounded to a degree of precision up to 0.00390625 (1/256th). I propose that had Backhaus' performance of Beethoven been quantized, all feeling would have been lost. For this very reason and for what I find slightly ironic is the fact that in Logic Pro (and no doubt other digital workstations) a parameter called Q-swing can be introduced which – in the case of Logic – varies the position of every second beat giving a purely quantized performance a more, well, un-quantized feel. A certain air of imperfection, in other words.
Once this idea is accepted the examples of necessary imperfection set against perfection in order to achieve balance are everywhere but – and this is key – they are all analog (or one could use the term 'organic'). Backhaus' playing. Equal-tempered tuning. Film grain. The ability of analog tape to absorb excessive electrical impulses before clipping the signals (a form of acoustic saturation, known affectionately as tape saturation). In an analog world and with analog devices, imperfection can be achieved to balance perfection. In digital and all of its binary code, there is no imperfection.
Although inextricably linked to this topic, I wish to avoid the clichéd argument of analog vs. digital (at least for now) and instead adhere to simply throwing out the idea of the necessity of imperfections all around us which allow for us to feel a connection – be it to a musical performance, Nature, those people we choose to identify with and so on.
Or just a slightly out-of-tune, mis-timed performance of a Beethoven sonata on a Bechstein grand by an aging genius named Wilhelm Backhaus.

This is bloody brilliant. I heard he covers this during soundcheck, but I was excited to find it on youtube. Enjoy, cheers.

my weakness.

"Nothing anywhere can rival the Grand Canyon."That was all he could muster so I too will not try. But standing on that precipice the sides falling away all around me into the depths of one of the wonders of our Earth lit only by the moon had me shaken. I trembled slightly then found the strength or sense of will to finally gather myself and started on my way back to a small, cozy room heater nudged up a warm bed right on the edge of it all.

autumn.
Fall is the time when birds fly south for the winter. I like it in fall when I climb the biggest tree at my house and I watch the birds fly. Another word for fall is autumn. The weather changes in autumn when it gets the perfect temperature outside. The French word for autumn is l'automne. In autumn, my family does a lot of raking leaves. I can make things out of leaves like forts and piles of leaves and jump in the pile of leaves. I can wear yellow, red, or orange clothes and climb a tree and stay still. It's like your [sic] camouflaged in the tree and nobody can see you. It's like your [sic] invisible. The trees look prettier that [sic] before. That's why I like autumn!
~ Julian, age 8 (I found this little story in his folder today)
parthenon crumbling.

I re-figured out a song tonight that I had written a while back (in this case, written meaning came up with in my head, transposed to the piano without ever actually writing any of it out and then promptly forgetting the chord progression while only retaining the key – in this case, B-flat minor). The trick is the change from the inverted B-flat minor to the inverted D-flat major but the whole progression is quite good. In any case, scrawling half-thought-out lyrics except for the line at the end (which I came up with at least a year ago) ~
like granite in time and marble walls I will fallI will fallI will fallI will fallI will fall for you
Maybe limestone in time .... (and of course that is sung with a rising crescendo as the music gains momentum and dynamics until it nearly literally explodes the piano massive fortissimo arpeggios big fat chords the guitars insatiable chords and arpeggios the bass arpeggios fuzzy and distorted the drums just for lack of a better term insane and the singer above all how he falls over and over and over). And I will continue to work on lyrics tonight.
And I received Logic Pro on my front porch tonight. And I am about the most excited I have been in a very very long time. And there are two manuals each about the size of a phone book. And I will be bringing both of them with me to Phoenix to read on the aeroplane. And my uncle may sell me his dual 1.25GHz mirror drive G4 if anything to use as backup (Logic Pro 7 is coded so that it can actually perform distributed computing and use CPU strength from across a network not to mention it was written for the G4 CPUs though granted trying to do a 64-track mixdown with each channel having a bunch of effects going all at the same time and bouncing that down to stereo might be tough .... ). And once I transfer the contents of my current Quicksilver G4's hard drive onto the new RAID I will set up once it arrives in the next day or two along with maxing out the RAM capacity on the Quicksilver, I will do a clean install of 10.4.11 before installing Logic. And yes this is all quite exciting. And yes I still need a USB MIDI interface and a pair of decent mics.
