Giving

As a child, Christmas was a “magical” time, a time of mystery and dark, a time of expectation and celebration, a time of giving and receiving.

My parents really enjoyed Christmas and enjoyed the part they played for their children. As kids we were always excited with what we were going to receive, especially the surprises along the way. Yet, we were also taught, and learned to enjoy giving as well. The balance was always there. That balance is a gift I treasure to this day.

To Sequence or Not to Sequence, That is the Question

Last night I took the simplified sheet music for Silent Night over to the synthesizer and powered up the electronics.

First I sat at the midi controller and slowly keyed the notes on the keyboard. I’m not good at reading music and picking out notes,  but before long I’d memorized the first eight notes: G, A, G, E, repeated twice. 

By the way,  this is the C major version.  Then I played those measures a couple more times and darn if I hadn’t memorized it.  That is mind blowing, because I’m “not supposed” to be able to do that.  

Then I sat down with the ER-101 Quad Sequencer and started entering notes.  Two weeks ago I had created a “cheat sheet” for that sequencer showing all of the notes that it could produce (99 of them) and correlated that with an 88 key piano keyboard. Then I added the peculiar notation used by the sequencer and created a matrix with the addition of midi notes.  This “cheat sheet” gave me the confidence to add the first 14 notes of  Silent Night into the sequencer. So I pressed “run”, and I sort of recognized the melody.  There were a few mistakes,  notably (pardon the pun) notes entered in the wrong octave.  Then I played it again and realized I had not entered anything resembling duration.  You see, this song has dotted quarter notes, half notes, eighth notes and other expressions of musical time. 

Adding duration to the notes took twice as long as entering the notes themselves. I understood the relationships between the lengths of the different notes, but had to come up with a quantification of the ratios. This time when I pressed “run” it sounded much more like the hymn. 

I’m still not completely satisfied because I’m not sure my tempo is matching up with the 3/4 time signature. So, I’ll practice my best SWAG (sophisticated wild ass guess) on it and see where it takes me. 

Then, I need to add the remaining 33 notes to complete the song, and set up the correct duration, and perform SWAG  for some of the calculations. 

I am excited about pushing the envelope (pardon the synth pun) on the ER-101. This has come about by a decision made about six weeks ago to dig deep into the basics of what I have.  It involved patching the ultimate basic patch and putting out a YouTube video explaining the patch. Then I pulled aside one module and did an in-depth exploration of the module and put out a YouTube video explaining it.  These explorations are primarily for my sake. I’ve learned over the years that if I study something well enough to explain it then this crosses over into the realm of deeper learning. Preparing to teach something helps me learn it. 


Today I walked past the band stands of the Alabama Symphony Orchestra.  They come to the cafeteria at Blue Cross Blue Shield of Alabama one day a year to play two Christmas concerts.   In between the concerts I dropped by the cafeteria to get a sandwich. As I casually strolled past the double bass lying on the floor I glanced up at the music sheet on the stand. Hah! All of his music is in the bass clef, I never would have even known that two years ago. This journey has been so much fun.

Who knew about this visual illusion, the Shepard's Tables?

I recently came across the Shepard's Tables illusion and was completely flummoxed.  Those tables just "cannot" be the same size.  But they are :)

Check out this link:   http://www.psychologyconcepts.com/shepards-tables-illusion/







Shepard's Parallelogram illusion




not my art..... it was borrowed from:
 http://www.cut-the-knot.org/Curriculum/Geometry/Shepard.shtml


Or how about The Dress?  This optical illusion is even more stunning because it is about Color!

It is still quite surprising that our perceptions can be “tricked” by reality!

Michael Was Worse Than I Thought

Hurricane Michael, while not directly causing a large number of fatalities, rearranged the landscape for tens of thousands of people and caused effects that will linger for many years.  The category 4 hurricane, which at landfall was only 2mph below category 5 status sent in a storm surge that nearly wiped Mexico Beach off the map. The barely weakening storm wrecked the east side of Panama City and roared north through rural Florida entering Georgia as a category 3 hurricane.  It appears that millions of trees, many of which were planted in pine forests to be harvested, were downed. People were being rescued from their homes for days after the passage of the massive storm.

In one place, that I first came to know and love in the 1990’s, the St. Joseph’s Peninsula, the geography was rearranged.  Hurricane Michael cut through the peninsula in two places, isolating the T. H. Stone Memorial St. Joseph Peninsula State Park.  Satellite imagery released by NOAA on October 11, the day after the impact of hurricane Michael showed the Gulf of Mexico flowing through the channels cut in the land.

I have loved “The Emerald Coast” for my entire life, even when folks called it “The Redneck Rivera”. The kitschy outdoor games, the beautiful bay, the unparalleled Gulf of Mexico with its sugar sand beaches have been an enduring part of my life.

If you can, please contribute to a verified charity that will endeavor to reduce the suffering of the folks along hurricane Michael’s path of destruction. The citizens of the Emerald Coast and those living inland who are digging out of the destruction will be grateful.

I've Got a Bad Feeling About Michael





I've got a bad feeling about Michael.  This hurricane popped up from a tropical gumbo where it stewed for a few days without any defined characteristics. Then, BOOM, this hurricane forms and it is tracking toward our beloved Florida Gulf Coast. The amount of shear (not so much) and warm waters (quite a bit) and approaching cold front are forecast to move Michael to the Florida Gulf Coast in less than two days.  It might "bomb" and explode in intensity bringing it onshore as a Category 3 hurricane.

I don't normally blog about this sort of thing, but there is a feeling deep in the pit of my stomach that this might be the worst hurricane to hit Panama City in my lifetime. I really hope this is not the case.

Prayers, crossed fingers and hopes - "please, no!"

Stay tuned...

Who Knew About Auditory Illusions?

My friend O.Z. Hall passed this on the Birmingham Electronic Music group’s FaceBook page today. This is quite an intriguing experiment, one that you can do alone which will cause you no discomfort.



While working on some deep learning related audio projects I came upon an interesting
auditory illusion that shows how our brain associates memorized phrases with auditory stimuli. Below is a sound generated by randomly stimulating a neural net that was pretrained on approximately 1000 recordings of brass sounds (both single notes and entire musical phrases). The resulting “drone” is totally uniform and has no temporal development at all (in the sense that there would be individual notes present in that mixture). If you first listen to the audio file it just sounds chaotic and maybe a bit disharmonic, nothing to see here, move along. But wait! Try running the file in the background for several minutes in a loop and you will notice that it appears as if there are suddenly notes, even entire melodies emerging from the mix. ” 1

Tonight’s Modular Synthesis Update

Well, this won’t be a daily feature but tonight there was some success in areas that needed it.

The DLD was patched to handle two Mother32s who were sequenced by the GRP R24.  Bingo! Each synth was running through a separate channel of delay simultaneously with its own custom delay time.  This not only worked beautifully but sounded great.

Later, using some radical off the wall patching the tELHARMONIC began to sing in a voice never heard before.  This patch will need documentation because most previous efforts to play this module ended in non excitement.

Lastly the TimeFactor was tested with each channel separately and it puts out beautiful delays as well. So it appears that four voices can be delayed separately.

The next goal will be to take existing stand alone VCOs and run them through one or the other of the delay paths.  The first test along this line using the ER-101 was not impressive. I’m sure that somewhere my technique went off the rails. 😀

The Weather So Far in 2018

It’s been a very busy year. One of the consequences of that busyness is that I’ve neglected to track the weather as close as I prefer. Tonight I ran through the F6 from the Birmingham National Weather Service (NWS) station.  The F6 is more widely known as the PRELIMINARY LOCAL CLIMATOLOGICAL DATA form.  The data in these forms are in all CAPS for some reason. One day I’ll look into why that is the case. Anyway, as I was saying, my investigations into the first nine months F6 forms and my comparison to the current Climate Normals yielded some interesting “headlines” for this years weather. 

First a small digression to provide a salient definition. “Climate Normals” are the current 30 year average of weather for each month of the year. The current Climate Normals are comprised of the averages from the years 1981-2010.  Every ten years the NWS puts out a new dataset. In the year 2021 they will deliver the next range of years for Climate Normals: 1991-2020. 

These Climate Normals are precisely what climate is: a thirty year average of thousands of weather measurements at the Birmingham NWS station. Every NWS station utilizes a set of data from which they derive their own Climata Normals. Using the Climate Normals and comparing them to our current year’s weather is the motivation behind this evening’s blog post. 

The first “headline” this data produces is: “The Month of February is Missing from Calendar Year 2018”.  Well, my calendar has February in it, and so does yours, so what does this headline mean? It’s actually quite simple. If you take the average highs and lows for this year’s February they are almost identical to the average highs and lows for the month of March found in the Climate Normals. This year’s weather just skipped the February temperatures and went from January to March temperatures.   And since this year’s March was just barely warmer then the March of the Climate Normals, this year we got double the fun!  Two month’s of March weather. 

The second “headline” this year is that the May-September period was hotter than the Climate Normals. This extended warm spell started out wet (6.98” in May) but ended up dryer than normal. July only saw 1.81” of rain at the bottom of the rain gauge. 

The third “headline” this year is that the weather in September was a clone of August.  So, this year we got two month’s of August weather, and that was following a July that was noticeably hotter than the Climate Normal.  As a matter of fact this year’s September was warmer than this year’s August! 

The fourth “headline” this year is a continuation of the last one.  “September is Hotter than the Normal July”.  Now everyone around here knows that July is the hottest month of the year. August is the second hottest month, followed by June. This year’s September’s temperatures were as hot as or hotter than the Climate Normal July. What we are saying here is that you could be more miserably 
hot this September than you could in the vast majority of the thirty year’s month of July (1981-2010).   Wow, that is hot!

The year is not over yet!  We just started the fourth quarter on October 1st so I’ll have to return to this topic in January for a look back at any future “headlines”. Until then, keep your eye on the sky.

Celestial Cruze


I’m not sure why this last piece of music has entranced me.  It’s not the most beautiful, not the most danceable, not even the most ambient piece I’ve recorded.  It resonates with me on an existential level and repudiates my conscious efforts to produce anything along the lines of Berlin School space music. There are no atmospheric cloud banks of sequencers pulsating at different tempos and timbres. The soft and sweeping violin pads are not to be found in this sound scape.

This piece is in a unique way a piece of me.  The drones expanding and contracting interrupted after a length of time with struck notes sounding like a gigantic collection of piano strings connected to a steel I-beam. Sound, echo, and silence feature and fulminate in a sometimes turbid, other times timid embrace.

This piece is not recorded to any media other than video, and hence is both a live performance never to be repeated, and a recording that cannot be edited later to correct errors or oversights.

Living and breathing, sounding and resounding, starting and finishing. From the depths of deep dark notes to high pitched three to five octave leaps and sweeps, this piece moves slowly toward its denouement.

The Seven Sisters in a Veil of Snow

This is how you know that you've waited too late to take a ride on the Blue Ridge Parkway.  I'm standing on the shore of Lake Tomahawk in Black Mountain, North Carolina looking north at the Seven Sisters mountain range. An early snow fall has covered the high elevations above 4,500' and rendered the parkway closed at that point. We were blessed with abundant sunshine in the valley below the peaks and even caught a rainbow on that chilly day in October 2017.

Arwen and her Pre Brush Communion

Arwen is by far and away the single most responsive cat we’ve had the pleasure of living with.  We’ve had a cat (only one at a time) for the past 37 years. The first two were Siamese, Arwen is mostly Maine Coon. She does not have papers to detail her bloodline, she was a rescue cat.  Her obvious and striking gratitude in being adopted was obvious from the first hour she connected with Debbie. The entire crowd in attendance (Debbie’s surprise birthday party) were amazed at how fast the two bonded.

Arwen has demonstrated to me, on hundreds of separate occasions that her command of the English language is far more sophisticated than expected. She picks up and responds to subtle conversations that Debbie and I have. Her daily expectation of her ritualistic grooming is delightful to see, and at times exasperating because typically my arrival from work coincides with her desire to receive the brush.  She knows she cannot get brushed until we “meet and greet”.  This ritual is played out every afternoon at some point in time between 4:30 and 5:30.  She awaits my movement to sit upon the ottoman. Once seated she comes up to me and rubs against my legs for dozens of times.  I’ll rub her as she passes by, or twirl her tail. She continues circling back in elaborate figure eights across the den floor and swipes both legs coming from the left. Then, in a mirror image of the previous maneuver she swipes from the right side. After some minutes of this slow motion activity she heads over toward the brush.

How Much Hotter is Your Hometown Today Compared to the Year of Your Birth?

The New York Times offers up a glimpse of how many of those 90 degree days we typically saw each year and how many we may expect to see over the next twenty or more years.


All you need to do is input the name of your home town and your year of birth. Note, the data set does not go back further than 1960, so those born earlier than then can use 1960.






https://www.nytimes.com/interactive/2018/08/30/climate/how-much-hotter-is-your-hometown.html?emc=edit_nn_20180831&nl=morning-briefing&nlid=8099462420180831&te=1


I'm going to "cheat" and give you the results from my hometown, Birmingham, Alabama.  In 1960 the temperature hit 90 degrees an average of 56 days a year.  Then we went through the well known short period when the climate chilled a bit in the late 60's - the 1970's.  I remember those times as snowy in the winter too!  Today, in 2018 I can expect an average of 69 days above 90 and by the time I'm 80 years old that figure is expected to be approximately 84 days!

Why don't you pick your hometown and give it a whirl?

Cruising for breakfast


Arwen has food anxieties. No, she isn’t starving and her bowl of dried food is never empty. She just wants to insure that her human caretakers understand the importance of receiving canned food on time and served with a flourish. This morning she “got in my face”about it, albeit with the sweetest demeanor. Yes, she will receive her breakfast in about five minutes!

What’s Going On

Well, after a hiatus I’ve returned to my blog and hope to keep up some semblance of continuity. We’ll see if that pans out. In the meantime I’ll close today’s activities with a link to one of my recent Modular musical excursions.

Vacation Books - Arwen's Recommendations




Image may contain: 1 person, cat


Vacation means many different things to different folks. One of the things I associate with a vacation is trying to pick up a “vacation book” to carry along and read when ever time and space allow. This past week I had two books to read. Both of which fit the “vacation book” criteria: not work related, not too intellectually taxing (no philosophy books), and interesting. Arwen has exactly the same criteria! She is sharing our vacation books with you. 

“Hope Never Dies” is a work of fiction (obviously), wherein Joe Biden and Barack Obama play the part of amateur detectives in unraveling the mysterious death of an Amtrak train conductor. This at times hilarious, and at times thought provoking novel is the work of author Andrew Shaffer, whose work “Fifty Shames of Earl Grey” established the author as a purveyor of malarkey! Arwen agrees that the book is pretty crazy at times but an entertaining and fast read. She recommends this book but refuses to give any plot secrets away. 

“The Stranger in the Woods” is the non fictional account of a man who walked into the woods of Maine and disappeared as a hermit for twenty seven years. Christopher Knight survived in the woods for almost three decades by ingenious survival techniques and by becoming an accomplished burglar. A lake community was terrified by the unknown and uncatchable thief who was highly selective in what he stole, and what he refused to steal. After being arrested his encounters in jail, court and with a community of people, and his difficulties in dealing with that transition are detailed in the book. The author also examines the life of hermits, and others who have walked away from mankind and dealt with solitude. 

Arwen likes this book because the hermit did not kill animals to stay alive. She recommends this book highly!

Snow again?

Well we had a beautiful snowfall in December here in Central Alabama and it appears we might get a small bit of snow tomorrow.


The above is a model depicting the forecast for noon on January 16, 2018. That is the 14:08 CST run of the WPC/NDFD model.



This is the official Birmingham, NWS timing map for tomorrow's freezing precipitation.

It will be interesting to see how this pans out!
