+
+00:00:02.800 --> 00:00:09.200
+I can yes
+
+00:00:09.200 --> 00:00:13.120
+okay um yeah so I'm uh zachary canfer
+
+00:00:13.120 --> 00:00:14.920
+let's go to the
+
+00:00:14.920 --> 00:00:17.520
+questions uh the first question uh why
+
+00:00:17.520 --> 00:00:19.119
+do we go top to bottom for time
+
+00:00:19.119 --> 00:00:19.840
+progression
+
+00:00:19.840 --> 00:00:23.920
+uh and left to right uh for low to high
+
+00:00:23.920 --> 00:00:27.279
+interesting I think uh so the initial
+
+00:00:27.279 --> 00:00:30.000
+uh thing I was copying that initial app
+
+00:00:30.000 --> 00:00:31.599
+work this way
+
+00:00:31.599 --> 00:00:35.280
+um and
+
+00:00:35.280 --> 00:00:36.960
+yeah I mean certainly traditional music
+
+00:00:36.960 --> 00:00:38.960
+you know on a staff uh
+
+00:00:38.960 --> 00:00:43.040
+does go left to right uh like this
+
+00:00:43.040 --> 00:00:46.000
+um I mean going top to bottom does make
+
+00:00:46.000 --> 00:00:47.440
+it easier to add more beats without
+
+00:00:47.440 --> 00:00:48.960
+having to wrap but certainly that could
+
+00:00:48.960 --> 00:00:49.920
+be managed
+
+00:00:49.920 --> 00:00:52.239
+um yeah I I had not really thought about
+
+00:00:52.239 --> 00:00:53.760
+it but it is definitely something worth
+
+00:00:53.760 --> 00:00:55.199
+looking into
+
+00:00:55.199 --> 00:01:02.480
+uh yeah you are now unmuted
+
+00:01:02.480 --> 00:01:05.680
+ah good point thank you let me go ahead
+
+00:01:05.680 --> 00:01:06.960
+and do that
+
+00:01:06.960 --> 00:01:14.240
+uh the entire screen
+
+00:01:14.240 --> 00:01:16.880
+okay so the screen share should be
+
+00:01:16.880 --> 00:01:18.320
+starting
+
+00:01:18.320 --> 00:01:21.439
+there we go cool all right uh
+
+00:01:21.439 --> 00:01:24.880
+two will be placed on the song um not
+
+00:01:24.880 --> 00:01:26.640
+now I can I can make some recordings of
+
+00:01:26.640 --> 00:01:28.080
+it or certainly you can try it
+
+00:01:28.080 --> 00:01:30.720
+um I couldn't quite get the the
+
+00:01:30.720 --> 00:01:33.119
+microphone and the webcam and everything
+
+00:01:33.119 --> 00:01:37.040
+to work with the sound playing now um so
+
+00:01:37.040 --> 00:01:40.079
+uh I can record some also please uh
+
+00:01:40.079 --> 00:01:43.520
+I put a link at the uh here in the uh
+
+00:01:43.520 --> 00:01:46.640
+etherpad https://zck.me/emacsconf2020 
+
+00:01:46.640 --> 00:01:48.479
+where you can go and get the source
+
+00:01:48.479 --> 00:01:49.920
+and you can try it yourself uh there's
+
+00:01:49.920 --> 00:01:51.920
+no dependencies needed so it's just all
+
+00:01:51.920 --> 00:01:54.560
+in Emacs um so please you know try it
+
+00:01:54.560 --> 00:01:57.040
+yourself
+
+00:01:57.040 --> 00:02:00.079
+any chance for an Emacs tracker or mod
+
+00:02:00.079 --> 00:02:01.040
+player
+
+00:02:01.040 --> 00:02:03.680
+um I don't really know what a mod player
+
+00:02:03.680 --> 00:02:04.479
+or tracker
+
+00:02:04.479 --> 00:02:08.000
+are but I mean I'm sure
+
+00:02:08.000 --> 00:02:09.679
+that would be cool uh maybe there's one
+
+00:02:09.679 --> 00:02:11.599
+on now but I don't know uh
+
+00:02:11.599 --> 00:02:13.920
+my musical background so I've played
+
+00:02:13.920 --> 00:02:15.200
+various instruments since about the
+
+00:02:15.200 --> 00:02:15.840
+third grade
+
+00:02:15.840 --> 00:02:18.160
+uh started recorder uh play cello I play
+
+00:02:18.160 --> 00:02:19.520
+guitar now
+
+00:02:19.520 --> 00:02:22.560
+um but yeah so just kind of random
+
+00:02:22.560 --> 00:02:23.680
+instruments and
+
+00:02:23.680 --> 00:02:26.959
+uh yeah I guess kind of some of those
+
+00:02:26.959 --> 00:02:27.280
+things
+
+00:02:27.280 --> 00:02:30.480
+influence how I think about music um
+
+00:02:30.480 --> 00:02:33.519
+uh yeah um
+
+00:02:33.519 --> 00:02:35.360
+are there any open source musical
+
+00:02:35.360 --> 00:02:36.640
+management sample libraries that could
+
+00:02:36.640 --> 00:02:37.840
+be used
+
+00:02:37.840 --> 00:02:41.200
+um good question I'm sure there are um I
+
+00:02:41.200 --> 00:02:42.400
+don't know any that integrate really
+
+00:02:42.400 --> 00:02:43.360
+well with Emacs
+
+00:02:43.360 --> 00:02:44.560
+one of the cool things that I liked
+
+00:02:44.560 --> 00:02:45.680
+about this is that there are no
+
+00:02:45.680 --> 00:02:47.440
+dependencies
+
+00:02:47.440 --> 00:02:49.360
+you know you don't need any external
+
+00:02:49.360 --> 00:02:50.800
+program to
+
+00:02:50.800 --> 00:02:53.040
+uh generate the music I mean it it does
+
+00:02:53.040 --> 00:02:54.160
+shell out to
+
+00:02:54.160 --> 00:02:57.280
+to play um but that
+
+00:02:57.280 --> 00:02:58.640
+should be able to be done on any
+
+00:02:58.640 --> 00:02:59.840
+operating system as always you have
+
+00:02:59.840 --> 00:03:03.519
+something that can play wav files
+
+00:03:03.519 --> 00:03:05.599
+um but yeah it is interesting to kind of
+
+00:03:05.599 --> 00:03:06.879
+try the different
+
+00:03:06.879 --> 00:03:10.000
+uh different sounds and different
+
+00:03:10.000 --> 00:03:12.239
+tones uh that you could get with
+
+00:03:12.239 --> 00:03:14.400
+different instruments
+
+00:03:14.400 --> 00:03:16.959
+have I written any actual songs um
+
+00:03:16.959 --> 00:03:17.599
+nothing
+
+00:03:17.599 --> 00:03:21.040
+super uh
+
+00:03:21.040 --> 00:03:23.680
+uh well put together just I kind of just
+
+00:03:23.680 --> 00:03:25.519
+been playing around with this
+
+00:03:25.519 --> 00:03:27.440
+it's kind of I making this was one of
+
+00:03:27.440 --> 00:03:29.040
+those things where like once I made it I
+
+00:03:29.040 --> 00:03:30.080
+was like okay
+
+00:03:30.080 --> 00:03:31.280
+now I can play with it and I did a
+
+00:03:31.280 --> 00:03:32.720
+little bit and was like I don't know if
+
+00:03:32.720 --> 00:03:33.920
+I feel like it right now
+
+00:03:33.920 --> 00:03:37.280
+you know which I've I've found that to
+
+00:03:37.280 --> 00:03:38.720
+be the case with some things that I've
+
+00:03:38.720 --> 00:03:39.599
+implemented
+
+00:03:39.599 --> 00:03:41.360
+in Emacs where it's I make it and then
+
+00:03:41.360 --> 00:03:43.519
+it's the kind of some of the desire to
+
+00:03:43.519 --> 00:03:44.480
+use it all the time
+
+00:03:44.480 --> 00:03:46.879
+goes away but I'm sure I'll circle back
+
+00:03:46.879 --> 00:03:47.760
+around
+
+00:03:47.760 --> 00:03:51.040
+at some point especially kind of maybe
+
+00:03:51.040 --> 00:03:52.400
+once I add in different tones or
+
+00:03:52.400 --> 00:03:54.640
+something
+
+00:03:54.640 --> 00:03:56.400
+I guess a similar question for
+
+00:03:56.400 --> 00:03:57.840
+pre-recorded sounds yeah I mean
+
+00:03:57.840 --> 00:04:01.120
+if it's part of what I did what I wrote
+
+00:04:01.120 --> 00:04:02.080
+was a
+
+00:04:02.080 --> 00:04:04.720
+wave generation library so if you kind
+
+00:04:04.720 --> 00:04:06.720
+of have the data
+
+00:04:06.720 --> 00:04:08.400
+you could use those and like chop them
+
+00:04:08.400 --> 00:04:10.159
+up and take certain lengths of them
+
+00:04:10.159 --> 00:04:13.360
+and make a wav file so it's not plug and
+
+00:04:13.360 --> 00:04:14.959
+play right now but you could certainly
+
+00:04:14.959 --> 00:04:19.120
+add those notes uh to do it
+
+00:04:19.120 --> 00:04:21.040
+um any knitting midi mapping
+
+00:04:21.040 --> 00:04:22.720
+possibilities um
+
+00:04:22.720 --> 00:04:24.560
+I haven't looked into it but I'm sure
+
+00:04:24.560 --> 00:04:26.160
+you definitely could output to midi
+
+00:04:26.160 --> 00:04:28.800
+um which is another benefit of having
+
+00:04:28.800 --> 00:04:30.400
+that multiple layers with the top layer
+
+00:04:30.400 --> 00:04:31.520
+is just like
+
+00:04:31.520 --> 00:04:33.360
+um you know if the root note is this
+
+00:04:33.360 --> 00:04:35.120
+we're just two semitones up or seven
+
+00:04:35.120 --> 00:04:36.560
+semitones up or whatever it is
+
+00:04:36.560 --> 00:04:38.160
+uh it should be relatively simple to
+
+00:04:38.160 --> 00:04:40.720
+kind of switch out that layer underneath
+
+00:04:40.720 --> 00:04:44.479
+uh from wave to midi or other things
+
+00:04:44.479 --> 00:04:45.759
+what were some of the challenges with
+
+00:04:45.759 --> 00:04:47.520
+writing a special mode for Emacs
+
+00:04:47.520 --> 00:04:49.759
+uh interested in getting into this not
+
+00:04:49.759 --> 00:04:51.040
+sure where to start
+
+00:04:51.040 --> 00:04:54.960
+um there uh yeah it so
+
+00:04:54.960 --> 00:04:57.120
+this isn't the first mode I've written
+
+00:04:57.120 --> 00:04:58.320
+um so that's right
+
+00:04:58.320 --> 00:05:01.759
+certainly that helps um I actually
+
+00:05:01.759 --> 00:05:05.600
+um I have a video that we recorded it
+
+00:05:05.600 --> 00:05:08.240
+as part of Emacs nyc on making a major
+
+00:05:08.240 --> 00:05:09.039
+mode
+
+00:05:09.039 --> 00:05:10.720
+that's basically like starts from
+
+00:05:10.720 --> 00:05:12.639
+nothing and kind of builds up to
+
+00:05:12.639 --> 00:05:15.680
+an implementation of tic-tac-toe um
+
+00:05:15.680 --> 00:05:17.039
+but so it kind of goes into printing
+
+00:05:17.039 --> 00:05:19.600
+things out and buttons and making the
+
+00:05:19.600 --> 00:05:21.280
+mode
+
+00:05:21.280 --> 00:05:22.800
+I mean one of the best parts about Emacs
+
+00:05:22.800 --> 00:05:24.560
+is because it's so
+
+00:05:24.560 --> 00:05:26.479
+uh configurable and so introspectible
+
+00:05:26.479 --> 00:05:28.479
+you can start pretty simply
+
+00:05:28.479 --> 00:05:30.320
+and just kind of asking max about things
+
+00:05:30.320 --> 00:05:32.320
+and then make one little
+
+00:05:32.320 --> 00:05:34.960
+change um it's really it's not that bad
+
+00:05:34.960 --> 00:05:36.479
+so uh
+
+00:05:36.479 --> 00:05:39.039
+I'll try to throw a link up on that uh
+
+00:05:39.039 --> 00:05:40.560
+on on that page I put up or
+
+00:05:40.560 --> 00:05:42.000
+please email me for whoever asked this
+
+00:05:42.000 --> 00:05:44.479
+question uh to get a link to that video
+
+00:05:44.479 --> 00:05:46.240
+um or just look at look at the source
+
+00:05:46.240 --> 00:05:47.919
+code of this or any other major mode
+
+00:05:47.919 --> 00:05:50.479
+um it it's pretty ems breaks it makes it
+
+00:05:50.479 --> 00:05:52.880
+pretty easy to extend uh
+
+00:05:52.880 --> 00:05:56.479
+major modes and I think that's that's
+
+00:05:56.479 --> 00:05:57.600
+the last question
+
+00:05:57.600 --> 00:06:00.240
+in the ether pad so uh thanks so much
+
+00:06:00.240 --> 00:06:02.479
+everybody for coming
+
+00:06:02.479 --> 00:06:06.720
+you are now unmuted uh thank you so much
+
+00:06:06.720 --> 00:06:09.039
+to curry for your awesome talk
+
+00:06:09.039 --> 00:06:12.960
+and for doing live questions
+
+00:06:12.960 --> 00:06:19.840
+thank you thank you cheers
