the lesson is learned; let the crate sink

jill and joe fought over opening the crate; they knew all the darkness inside, all the fear and terror, the troubles of the world, the pain

step in, create space, back away and think first; together we sat down and held hands around it and asked, Why open? What lesson is there to be learned?

in front of the crate, we already had the lesson there, on a thin slip of paper:

do not trust genius, narcissism, charm; great accomplishment can give rise to pride, the worst of the seven sins. pride can take a person down, and many others with that person.

so we have the lesson. it is there. there is no need to keep the crate now. let us drop it, let it sink to the bottom.

I command jill and joe to carry the crate to the edge of the ship, no strings attached. It drops into the ocean with a splash, white wash flying up, but then gone. briefly we see its dark brown exterior sink deeper, deeper... into blackness. it'll be at the bottom of the sea, along with probably thousands of other crates, many of which far larger. the sea is ridden with evil crates from the world, horror stories, but we take the slip of paper from it - the lessons - and let these crates fade away to nothingness.

this one is gone.

there may be small bubbles that come from bubble, little slips of paper that look tempting to grab. we should fish them gently, but not dive deeper into the realms below, because only drowning can be found there.

fish carefully; create space, lots of space, at any site of faint bubbles arising; do not rush, do not be overeager; be patient, gentle; this is something jill should not jump in for; just gently notice the bubbles coming up, let them sit at the surface for a while; only later on, will a slip of paper bubble up to join, and that small thing should be snagged gently, barely scraping the surface of the water

may we return to guiding our ship, navigating these waters, finding peaceful views of glaciers, green forests, beautiful land, beautiful sky

a mind divided - captain of the ship: jill and joe people

people call me one name, generally
(other languages aside)

but in my head, there are actually multiple

d is the captain of the ship, the one who steers and navigates the storms, calls out when he spots land; draws cheers, encouragement; gives rise to celebration

then the crew members, none of whom act with space between stimulus and response:

jill people, the emotional, the irrational, acting through spontaneity; these people have instincts, can sense emotions; are eager to take action quickly

joe people, the stolid, quiet, hard workers; those who can be depended on for robotic tasks, but who focus too much on conscious logical decision-making, not enough on gut feeling, often deliberating too much

d should balance his crew members, draw from the behavior of the crowd, and decide how to navigate the waters
jill people and joe people

it's about balancing intuition with reason, and keeping plenty of space between stimulus and response

shroud

A shadow of a portrait that I once held on the wall
People still stop and admire, rest their chins in their hands and thoughtfully smile
But I have since took down the frame
And let the dust settle on it from afar

An occasional smile, glance, eye contact
But usually her hair shrouds her queenly image
a sliver of brilliance; a whole history of accomplishment hidden

wispy conversation. defeat.

some people we talk to, the words just vanish into thin air. wisps. as though the conversation never even happened. no substance, no real buildup in getting to know each other, no consequence.

--

defeated. but in defeat, there is great simplicity.

Basic audio engineering - USB-MIDI cable, y adapter, stereo/mono/TRS/TS understanding

Background

I had decided to purchase a USB-MIDI cable online, and I was delighted to find a cheap one costing < $5.00: http://www.amazon.com/gp/product/B001LJUVO4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1. When it came, no setup was required other than plugging it in. It seemed to work well, transmitting notes from my keyboard (a Yamaha P95-B) to GarageBand. 

But the problem came when I depressed the pedal: The software did sustain properly, but it also registered a blatant E note. The E note is unacceptable for me because I use the pedal often when I play piano, and it completely interferes with whatever I'm playing.

Consequently, I searched online for a solution. It seemed many people had had this issue: "Pedal plays an E???" (Apple discussion thread). Unfortunately, there was no clear answer. When I search for solutions online, I try to find multiple sources that describe the same answer - not only to get multiple perspectives for more information, but also for higher confidence in the solution.

Some people in stores suggest the problem is on the software's side, or the keyboard's side, or the pedal's side. This is possible, but in this specific case of the pedal playing an E note but also doing the sustain properly, I have found the issue to be in the specific cable. 

One answer in the Apple discussion at https://discussions.apple.com/thread/3122897?tstart=0 describes that the cable is the problem, too:
Well, my problem has been solved.

I coughed up AUD$49 and bought a branded USB-to-MIDI cable and the sustain problem has disappeared.
But there's no explanation for why a more expensive MIDI-USB cable might solve the issue for people in general. So I called Yamaha to ask about the keyboard, and see if it was truly the keyboard's problem or the cable or something else. This is what I learned:

Solution

Basically, there are 2 kinds of MIDI cables: "class compliant" and "proprietary." Class compliant are the cheaper ones, typically $3-15. These can work for basic use, but they lack support for the appropriate drivers, so they may behave erratically, playing arbitrary notes or not registering sounds at all. Proprietary ones are more expensive, usually >$40. These support the appropriate drivers.

To set up proprietary MIDI cables, you must ensure your computer has the proper drivers; if not, go through an install process to obtain them. For Mac, that amounts to simply downloading the right driver from this site: http://download.yamaha.com/search/detail/?site=usa.yamaha.com&language=en&category_id1=16277&category_id2=16279&category_id3=16298&product_id=107905&asset_file_language=EN&asset_id=57163. He said that the "UX16 USB MIDI driver" would work for me.

In summary, the problem was that the cheap cable that I had ordered lacked the proper driver support to interpret the pedal properly. According to the Yamaha support person, proprietary MIDI cables have proper support for these drivers, so buying a proprietary MIDI cable, which is more expensive, and then downloading the right driver on your computer is likely to solve the issue.

Why get a MIDI-USB cable to begin with?

My friend on the phone was of the talkative type, and he went into much more detail than I had anticipated. I'm grateful he did so because he actually helped me solve a bigger issue in my plan to record better music with my keyboard.

The whole reason I wanted a MIDI-USB cable was to record my keyboard playing more precisely. However, MIDI-USB cables don't transmit sound; they just play an existing sound on the computer in the GarageBand or Logic Pro library. The quality of the sound file may be better depending on the library of sounds available, so Logic Pro's library may sound better than GarageBand's library. But the point is that since no sound is transmitted through the cable, the nuances in piano playing are lost - you know, that expressive musician stuff. Granted, MIDI provides lots of benefits. The notes are editable in digital audio workstations (DAW) like Logic Pro, and you can change the instruments easily after recording. But for me, the nuances of music are more valuable, and I intend to record songs in one go and with minimal editing with a DAW anyway.


Understanding terminology

After explaining that I have a Scarlett 2i2 interface by Focusrite (http://us.focusrite.com/usb-audio-interfaces/scarlett-2i2), which accepts 2 inputs, he gave me this recommendation:

To keep nuances of the keyboard, I should get a Y-cable. Specifically: "a Y adapter/cable with a stereo miniature male on one side and a mono 1/4 inch male on the other side." I didn't know how to interpret this initially, but after asking around and reading, it's not so difficult.
  • male refers to the pointed end of a cable; female refers to the hole/receiving end of the cable.
  • 3.5mm (about 1/8 inch) is the common size for plugs into laptops and mp3 players. Think Apple earbuds or the typical headphone jack of a laptop - that's 3.5mm. 1/4 inch is the larger size for lots of audio equipment.
    • So, by "miniature" he probably meant 3.5mm (1/8 inch), since 1/4 inch is probably the standard among audio engineering.
    • I had told him I had a way to connect my regular headphones to my keyboard, so this is probably why he said "miniature". But my method requires using a converter from a 3.5mm female (F) to a 1/4 inch male (M). So, getting a 1/4 inch on both sides for the cable works better because then I don't have to use the converter.
  • There are two types of sound systems: mono and stereo. 
    • From http://www.diffen.com/difference/Mono_vs_Stereo:
      • Stereo (or Stereophonic sound) is the reproduction of sound using two or more independent audio channels in a way that creates the impression of sound heard from various directions, as in natural hearing. 
      • Mono (Monaural or monophonic sound reproduction) has audio in a single channel.
    • Since stereo reproduces sound in 2 independent channels, it makes sense that the y-adapter splits off - the end with one part is the stereo side, and the end with two parts is the mono side.
    • You can differentiate Stereo and Mono by looking at the number of stripes on the metal part. The stripes are insulation; the metal contact bands are the channels, with one extra for ground. So 2 metal bands means mono, and 3 metal bands means stereo. This explains those TS/TRS abbreviations we see on lots of cables/converters.
      • TRS = tip ring sleeve = names of 3 metal parts = stereo
      • TS = tip sleeve = names of 2 metal parts = mono
Finally, this is the cable I ended up ordering: http://www.amazon.com/Hosa-Cable-STP203-Dual-Insert/dp/B000068O1P/ref=cm_cr_pr_product_top/190-6296940-4917419. You can see the metal bands right in the picture.


The 1/4 inch stereo side fits into my Yamaha P95-B's headphone jack, and the two 1/4 inch mono sides fit into my Scarlett 2i2 interface's two inputs. They work great.

Then I can put headphones into the Scarlett and listen to myself play as I record.
