You are not reading my b.log using HTTPS. You can switch to HTTPS by clicking here. Yesterday...Yesterday, I mostly worked on SimpleSeq, as I was putting together This One Weird Feature and really wanted to get it done.But sitting at a chair all holiday. Nah, that wasn't good.
So I also painted one of my shutters.  Using the living room as my workshop - eek!
The heat gun was useless. I went from 400°C to 600°C in 50°C steps, and all the gun really did was make the paint a bit soft. It didn't bubble and it wasn't possible to just scrape it off. Eventually I just gave up on that and scraped off the flakey parts, lightly sanded the rest, and threw on a coat of white gloss. Since the smell was pretty awful, I went shopping. Got myself a lot to drink, as it's been quite hot and I really can't stand the taste of water. I've been drinking tea or milk. So now: grape juice, apple juice, pineapple juice, lemon juice, and a brick of some horrifically expensive Starbucks stuff that has so little actual coffee in it that even I can manage it and I don't like coffee...
SimpleSeq v0.06Having finally tracked down a copy of Midiphile and getting it to work under Aemulor (it's a shame the sources aren't available to build it as a modern 26/32 bit neutral app), I discovered a couple of flaws in the MIDI exporter, which were fixed. The first was a slightly incorrect chunk size. I had, as a last minute thing, added the time signature to the file but forgot to account for those extra bytes in the calculation.The second thing was that the output ends at the end of the data, which is logical enough, except that notes that are still on won't have been turned off. Most MIDI software will assume this upon reaching the end, but still, it's not hard to go through at the end to ensure every note is actually off. If you turn on the extended report, you'll notice Midiphile throwing up errors about Duplicate Events and Excess Note Off commands. I believe this to be a bug in Midiphile, as if we look at the A2 key's report: 001:03:000 Midi NoteOn 1 A2 v:44 001:03:006 Midi NoteOn 1 A2 v:0 D 001:03:006 Midi NoteOn 1 A2 v:44 F 001:03:012 Midi NoteOn 1 A2 v:0 D 001:03:012 Midi NoteOn 1 A2 v:44 F 001:03:018 Midi NoteOn 1 A2 v:0 D 001:03:018 Midi NoteOn 1 A2 v:44 F 001:04:000 Midi NoteOn 1 A2 v:0 D 001:04:000 Midi NoteOn 1 A2 v:44You can see what's actually clearly happening here is that the A2 note is being turned OFF, and then immediately being turned ON again. It's not actually a duplicate event, I suspect the program is only looking at the "NoteOn" event and not taking into account that a Note On with a velocity of zero is actually a Note Off event. The second new thing? This is the biggie. Transcribing.
 Play music, have it appear. This isn't perfect by any means. As it needs to make the notes fit to the time duration of each individual column (which is 12.5cs at 120bpm; or 16.6cs at 90bpm), there may be small errors, particularly with fast notes. However it does attempt to record exactly what was played, including full expressiveness (that is to say, it will record the use of the Sustain pedal and the exact key velocities if your piano supports touch sensitivity). This is an example of me bashing out "sort of" the beginning of Twinkle Twinkle Little Star.  Recorded with full expressiveness. And since we can now export MIDI, we can drop this into Rhapsody4 to see what it looks like as notation, but note that the MIDI import lost the use of the Sustain pedal and the individual note velocities, so when played back it's rather... flat.  Music that looks like music but with no expression.
In order to transcribe, simply line up the edit highlight with the beginning of a bar, and press
You'll see the dialogue above as it counts beat ticks. There are two noises that you'll hear. The most common is the high-hat pedal which marks each beat. Every so often you'll hear one that's more tish (high hat open) that marks the start of a new bar.
As recording is performed in real-time, the dialogue will keep you up to date with what is going on. When you are finished, press Transcribing will merge the notes played into the current music (in the current channel) from the bar selected, so you could use this to enter a piano piece to be played by two people. Note also that it will automatically overwrite any notes or control sequences that were previously at those locations; but remember it'll be playing a beat ticker, not what was there before. It doesn't echo your playing, it works on the assumption that your piano has already sounded what keys have been pressed. Events other than Note On, Note Off, and Sustain pedal are ignored.
Remember, the shortest interval supported by SimpleSeq is that of a semiquaver (or a quarter of a beat). Hammering the notes out as fast as you can may... not behave as you expect. SimpleSeq has some special code to cater for notes that are both on and off in the same time interval, but even so you might find things being a bit odd.
That being said, if you want to see if you have what it takes to join a thrash metal band, then simply set the BPM to 360, hit
I'm actually really pleased with this work. As much as I've been adding features to SimpleSeq here and there, I didn't feel that it could be taken seriously as a music creation tool until it had the ability to record what the player was actually doing, in real time. Better yet, since we're working with MIDI events here (rather than trying to convert to notation), we can perform a more accurate recording where the use of sustain and each individual key hit can be faithfully recorded.

And in case you need it given the perpetual lack of a user guide... Some random stats:
CandlelightSince it's getting darker earlier now (we're almost to the equinox, OMFG), I decided to fire up the candlabra to see what it was like in actual night conditions.Well, after giving it a few minutes for the wax to melt (it's the fuel) and for my eyes to adjust to six candles rather than electric bulbs, it was... surprisingly capable.
 Candle light. Once the candles had warmed up to full intensity, it was quite possible to read or play the piano, plus a lovely orange hue to the light that just said "home" in a way that LED bulbs can't manage.
No, we haven't been visited by aliensNot so long ago, the US Congress actually gave time and space to those pushing for "the truth" about alien visitation.Now it's Mexico's turn. Complete with a thousand year old corpse that looks surprisingly human. The problem is, like the Earth being flat, it just doesn't stand up to any reasonable form of scrutiny. Because if we had been visited by intelligent extraterrestrial life, we would know about it because there's a pretty good chance that it will have either enslaved us, wiped us out, or maybe died trying (refer to H.G.Wells' The War of The Worlds and John Christopher's The Tripods for examples of how that would go). The reasoning here is simple and multifaceted. Firstly, there are no alien civilisations nearby, we'd have noticed by now. So they would have to have come from a long way away. Which means one of three things. Either they have extremely long life spans, or they have perfected being put into stasis, or they have the ability to defy the speed of light (either directly or by using wormholes). Each of these imply a level of technology far in advance of anything we have. Or, put it like this. Imagine an alien ship hovered into orbit and pointed its cannons at us - including, obligatorily, making their point by blowing up Washington DC...though it would be funny-tragic if they instead wiped out somewhere like Riyadh or Beijing and ignored the US completely. What we think as the most important centre of power on earth might not be how they perceive it. We have a heavy dependence on oil, which means the Saudis carry weight, and damn near everything is produced in China which means... you get the point.
Anyway, what do you think our response would be? Given that we're quite adept at killing each other, but killing something from somewhere else is an outside context problem, would we even be capable of making a response?
Oh, but wait. They might be friendly aliens looking to share their secrets with us... Firstly, any alien needs only look at conservatives of any flavour (from Republicans to Tories and whatever the equivalent is elsewhere) to understand that we simply cannot be trusted with that level of technology. 49% of our species openly and brazenly subjugates 51%. We're quite happy to murder each other based upon such trivial nonsense as differences in skin melatonin, country of birth, or "my imaginary sky fairy is better than yours", or maybe just because something else somewhere else "offends" them (which, of course, entirely justifies brutal murder, right? - that crap offends me, so who do I get to kill?). Besides, if they're a great starfaring species, the way they protect themselves is exactly by not sharing their secrets. Being able to do what others cannot gives them power, supremacy, and protection. Just like here on earth. Thinking that aliens would want to help us is part of the egocentric "humans are special" nonsense that religion teaches. No, we really aren't. We're a primate that's figured out how to split atoms. That makes us special here, on this planet. It doesn't amount to a hill of beans in the universe. Plus, of course, we're assuming here that coherent communication is in fact possible. Maybe they have developed (or been evolved with) some form of telepathic communication, so they have no need of vocal cords or the ability to distrupt the electromagnetic spectrum. And, being from somewhere else their entire thought process will be different. We struggle to understand Lucy Letby. How would we cope with a lifeform with a morality isn't so much white/grey/black as pink-with-mauve-patches? Secondly, there's plenty of evidence in our own civilisation that pretty much the only reasons we went anywhere were to plunder or colonise. Those we didn't outright kill, we enslaved or held subserviant. As a Brit, we nearly ruled the world. And might have, if those in power had cared a little more about the ruling and a little less about the pilfering. This is a very viable consideration as if the aliens are that advanced, they would likely regard us like we regard cattle - "essentially stupid and exists only to make milk and be slaughtered for meat". They won't care about us or our feelings and opinions any more than we care about the animals screaming in fear as they're led to their demise. So, no, they wouldn't sneak into remote Ohio farms to abduct cows and shove probes up the rectal passageways of random humans in the middle of the night. They wouldn't send little scouting parties to perform experiments on us. Because if they came here, they came here for a reason, and like the Conquistadors they'd turn up with enough show of strength that we'd learn pretty rapidly the futility of fighting back. They would be here for whatever it is they wanted, and we would be the annoyances getting in the way of that. No, they absoutely would not see us as equals. They've travelled the cosmos, we've made it to our own orbiting satelite. They'd be here for carbon, for water, maybe we're the only decent source of beryllium? Whatever, they would not be here for us.
So, with all of that in mind, I call "bull" on the whole alien visitation thing. If they had come, we'd know. Well, those that survived, at least.
