0:04welcome to another story with your key
0:07stage so in this tutorial I'm gonna talk
0:09about MIDI aliases input and output
0:11aliases so media leases are basically
0:14placeholders for actual MIDI connections
0:17virtual or actual connections but they
0:20also contain lots of additional
0:22information and routing options and
0:24specifically with this new version 1.5
0:27MIDI Ellis's have many more
0:29functionalities like you know
0:31translating signals routing or combining
0:34different signals from different
0:36different MIDI ports so what are the
0:39uses of media lists so apart from using
0:42different names for MIDI ports media
0:45Ellis's play an important role of
0:47changing certain functionalities of
0:49sindh apps or midi controllers one of
0:52the biggest challenges of using his
0:54stage with multiple scene taps or midi
0:56controllers is that almost every scene
1:00tab has a different behavior when it
1:02comes to processing MIDI messages the
1:05way they respond to MIDI messages
1:06instant messages or parameter messages
1:08are are usually different in different
1:10synth apps and there are tiny differ
1:13differences which might cause problems
1:15when using them in a live setup
1:18so these media lasers have specific
1:20options which allows you to adopt key
1:23stage to be able to you work with those
1:25instant apps so let's start with input
1:28aliases
1:33okay now we access media aliases from
1:36preferences MIDI connections so the
1:38first part is for input aliases and the
1:40second part is for output aliases now
1:43this is a freshly installed key stage
1:46except I installed some instrument
1:48process for demonstrational purposes but
1:51if I click this list of MIDI aliases I
1:54can see that I already have six MIDI
1:57eleazar's automatically created and
1:59these are their ones that I created for
2:02actual MIDI inputs and these actually
2:05cannot be deleted when I create a track
2:07here the lists that I see here is
2:10exactly the same list so what I'm
2:13actually choosing here and this list are
2:15medialis is not just connections but
2:17media races with all the additional
2:19information but now I'm gonna create a
2:21new one let's name it my main keyboard
2:25so this is a new editor window for input
2:28aliases with one point five here are the
2:32list of actual inputs so I can add more
2:36inputs or I can delete them and for each
2:39input I have a bunch of filtering and
2:43translation options but here I can
2:45choose the actual inputs here so here's
2:48my North keyboards and now if I go to
2:51the track and look at the lists now I
2:53have this additional main keyboard which
2:57receives signals from from north itself
3:00so for the output list choose Jordan
3:02Tron channel 2
3:08okay and let's create another track with
3:12again my main keyboards and choose
3:15another synthesizer let's say it's on
3:18riser so I have two tracks with the same
3:23MIDI input alias now suppose that I have
3:26to switch my keyboards and use another
3:28keyboard with with my setup with all the
3:31songs so normally what you need to do
3:34here is you have to choose the new input
3:37for each track in each song but within
3:40MIDI input aliases you don't need to do
3:41that you simply create a new input and
3:44here is another keyboard that's
3:46connected which is launch key so now as
3:50soon as I activated launch key you can
3:52see that it sends signals to both tracks
3:54and if I disconnect my note keyboard
3:58here you can see that the North keyboard
4:01now shows in red text which means that
4:03it's not connected the input alias still
4:06knows that whenever an old keyboard is
4:09connected it will start receiving
4:10signals from there but right now it's
4:13not connected but launch key is
4:14connected so I can get signals from here
4:17but if I connect back north
4:19all the tracks of with main my my main
4:22keyboard will start receiving signals
4:24from north okay now I'm gonna
4:26demonstrate these filtering options and
4:28these custom translators by splitting my
4:32North keyboard into two MIDI eliza's so
4:35my north keyboard has two pedals one
4:37expression pedal and one switch pedal I
4:40want to create different midi input
4:42elias's for the expression pedal and for
4:44the switch pedal so let's create another
4:46input Allies and this is going to be
4:48expression pedal experto
4:51so the input will still be north
4:57and what I want to do is I'm gonna
5:01filter out all the signals except the
5:03expression pedal signal and I want to
5:06wrote that expression pedal to volume
5:08so let's first add a custom translator
5:12so expression pedal sense control change
5:16number eleven and my output will be
5:19volume so the expression pedal is now
5:22converted to volume but this Alliance
5:25also get signals from all of the control
5:28change parameters and also note signals
5:32I don't want that so I can filter notes
5:34here and I can filter everything but
5:40here what it says filtered signal types
5:43for non translated messages so in fact
5:46any translated message here on these
5:48custom translators are not affected by
5:51by these filters so even if I also
5:54filter all the control change signals
5:57this translator will still work and the
6:00incoming control change number 11 will
6:02be converted to volume and will be
6:04routed to the expression pedal media
6:07lines I will not be affected by by these
6:10filters so that's why it says
6:12untranslated messages that's important
6:15so input channels will be all channels
6:17it doesn't matter and output Channel
6:20will be the same as the incoming Channel
6:22okay but the problem is I don't want
6:27that expression title signal on my North
6:31keyboards sorry on my main my main
6:35keyboard so what I need to do is I need
6:39to create another translator and block
6:43this control change 11 on my main
6:47keyboard so let's try it so suppose I
6:53add this expression pedal to Jordan drum
6:55but I don't add it to the Sun riser so
6:59let's create two parts here
7:02inaudible our maps to both Jordan throne
7:06and sunrise about the expression pedal
7:07only controls Jordan Tron and controls
7:11water
7:12[Music]
7:15I'm basically do the same thing with the
7:18switch pedal
7:23now let's go into the output earliest
7:25for sunrise er now just like in input
7:28aliases the output aliases that are
7:30created automatically cannot be deleted
7:33and their actual outputs cannot be
7:37changed but unlike input aliases output
7:40Elisa's can have only one actual output
7:42one media output connected so the next
7:46option here is the instruments I've
7:48already gone through this in the second
7:51tutorial video so for every LS you can
7:53assign an instrument presets but here
7:56you can also access the database for
7:58suggestions for Eastern preset
8:00suggestions for your output at lists but
8:03I already downloaded one so I don't need
8:05that so this button is new so now you
8:08can add custom translators just like in
8:10input aliases here and you can change
8:14the output channel or your output
8:17address I'm gonna skip these two options
8:21because I don't spend more time on them
8:23here we can change the default channels
8:25and default colors of your output areas
8:28so for example if I choose like six and
8:31seven as my output and change defaults
8:33to blue whenever I create a track and
8:37choose sunrise er it automatically
8:40becomes blue and its output channels are
8:42automatically becomes six and seven so
8:44these options has to do with instant
8:47messages which means program change em
8:49bank select messages and when they
8:51should be sent on what are conditions
8:53they should descend so I will go I start
8:56with this option the first option so it
8:59says sound only when the instrument is
9:01changed so what does that mean now
9:05suppose that I create a part and choose
9:07an instrument here let's say signature
9:09leads and I copied this part to another
9:14section now both paths have the same
9:17instruments the same program change
9:19number and the same Bank select messages
9:20and normally when I select a section the
9:24instrument message is automatically sent
9:25but key stage keeps track of the
9:29instrument for each track and when this
9:32section is activated sound only
9:34instruments messages when it's changed
9:36it
9:37doesn't change the instrument message if
9:38it's the same instruments so even if I
9:41select these sections no instant
9:43messages are sent to sound riser but if
9:45I create another track here apart here
9:47and select another instrument this time
9:52issue is just sent you can actually
9:54understand it because sunrise it cuts
9:56the sound when it changes the
9:57instruments so this is pretty convenient
10:00for sunrises because when the same
10:03instrument is selected on both parts you
10:05don't want to cut the sound only when
10:09you need to change the instrument the
10:10sound cuts and the new instrument is
10:13loaded on sunrise err but for example
10:17for Jordan Tron
10:22so Jordan Tron is another synthesizer a
10:26Center has a different behavior in terms
10:29of changing instruments so for example
10:32when I choose this route here and let's
10:38choose the outputs allows for Jordan
10:41Tron and let's select always Sony's from
10:45messages now even if I are the same
10:50issue is it sent Jordan Jordan Trump is
10:54smart enough to know that it's the
10:56current instruments selected and doesn't
10:59cut the sound doesn't change the
11:00instrument now going back to sunrise err
11:03I'm going to show you this third option
11:05this is the option that I almost always
11:07used in almost all all instruments or on
11:11all apps so sand when the instrument is
11:14changed or when the active part or
11:17section is reselected so what do you
11:19mean by the active part it's basically
11:20the part the section that is highlighted
11:23with this vertical strip so for example
11:26so it's a signature lead when I change
11:29the section the instrument message is
11:32not sent because it's the same
11:33instrument but the same section and
11:37again this is especially useful when you
11:40want to adjust your instruments and
11:42reset it reset its parameters so for
11:45example I have this part
11:48change attack time on this part and when
11:55I activate this part the instant message
11:57is not sense I still have the fire at
12:01that time but I know that the original
12:02state of the issue it has zero attack
12:05time so when I tap it again these two
12:10move is a descent and attack time is
12:12reset it's so for each synthesizer you
12:14may choose one of these three options
12:16depending on how you want to use key
12:18stage you know it really depends on if
12:22whether you want to use key stage on a
12:25progressive way like I do like you know
12:28every section corresponds to a section
12:30of a song or I know that some people
12:32uses key stage as a sound module like a
12:36sound module sound selection unit where
12:39each section corresponds to a different
12:41sound on your keyboard so tapping the
12:44same section sends this instrument
12:47messages or not depending on your choice
12:49here where this last option is also
12:52quite important and to demonstrate it I
12:55want to select another synthesizer here
12:58valia and choose my North keyboard here
13:02or main keyboard oops sorry
13:06so guardedly also uses channel 2
13:13alright let's create a part here and
13:16choose an instrument now let's say I
13:23change some of the parameters here
13:26suppose I add some simulation
13:39to the sound now when I select this
13:44section here the instrument message and
13:47all the parameters are sent to get there
13:49but when I play my keyboard I can hear
13:51the original instrument it looks like
13:53all these parameters that I changed did
13:57not apply to Galera and this is mainly
14:00because of the following whenever and
14:02whenever Godley receives a program
14:04change a bank static message it starts
14:06loading the corresponding instrument and
14:09while it's loading so it takes a certain
14:13amount of time for Galu to load that
14:15instrument and during this loading
14:17procedure it doesn't accept any signal
14:19it doesn't accept any other parameter
14:21signals and since these messages are
14:24sent simultaneously well they basically
14:27disregard these signals and unload the
14:30instrument with its in its original
14:31state but now if I go to the other areas
14:35of Gallia I have this option so see if I
14:41choose a number here like let's say 40
14:45now for the after 40 milliseconds the
14:49parameters will be sent so let's let's
14:51try if this period this amount of time
14:53is sufficient for girlier doesn't look
15:01like it's sufficient or because
15:03sometimes the loading time changes so 40
15:07milliseconds might not be perfectly
15:09sufficient so you might you maybe easily
15:11have to experiment with this number and
15:13choose the optimum amount of time for
15:16the part parameters to be sent to the
15:17corresponding instruments and let me
15:24show you if I choose a high number here
15:27and when I so just look at the MIDI in
15:32and out lights here you can see that
15:38there is a gap between the first of the
15:40first blink corresponds to the
15:41instrument message and the second link
15:43corresponds to the parameters
15:49so in this final part I want to actually
15:51build a technical example with with the
15:55north's output actually this is this is
15:58a setup that I use for the for the media
16:01allows for for North let me briefly
16:03describe the behavior of north so note
16:07Elektra has to sound engine 3 sound
16:09engines inside and you can actually
16:12control two of them simultaneously so
16:15there is this main channel I I changed
16:17it to 16 so as I play this fancy as I
16:25send many messages to this channel you
16:27can hear both PR and distinct sound but
16:31you can actually control these two songs
16:35separately I assigned one of them to be
16:39channel 2 so channel 2 corresponds to
16:42the first synth engine let me actually
16:45copy and paste and channel 3 is the
16:49second
16:52so people use only the first part and
16:54[Music]
16:56use North's inbuilt features like
16:59splitting and layering to control both
17:02synthesizers but since I have key stage
17:05I want to independently control these
17:08instruments well it looks like I can
17:11independently control with these two
17:13different tracks but there is a catch on
17:17the main channel all these volume
17:19changes and instruments messages I can
17:24be received but on these channels none
17:30of them work basically does respond to
17:36any of these messages parameters or
17:39control change and program change
17:41messages on either channel 2 or 3 every
17:45time I need to change the instruments I
17:47need to create a part corresponding to
17:49channel 16 change the instrument there
17:51then mute it and then work on on the
17:55other two tracks this is something that
17:57I don't want I really want these two
18:01channels these two tracks to act
18:03independently being able to change the
18:06instrument and also the parameters on
18:08this check tracks independently so in
18:11order to do that I'm gonna go into the
18:14output alias corresponding to note and
18:17go into translators so I want to wrote
18:21all the program change and control
18:23change signals to channel 16 now I add a
18:27custom translator now the custom
18:28translators has a couple of new options
18:30with 1.5 one of them is I can actually
18:34control change any control change signal
18:37so the input doesn't have to be a
18:38specific control change but it can be
18:40any control change and whenever I have
18:43any control change as the input I have
18:46this additional option as same as input
18:48so the same control change signal is
18:52routed to the outputs
18:53okay so right now basically nothing
18:55changes there's basically the same
18:58control change but we also have now
19:01control over channels for custom
19:04translators so the
19:06chuckles and translators can manipulate
19:07the channels of incoming signals so what
19:11I want to do is I want to wrote these
19:14signals to channel 16 and I want to do
19:19the same thing for the program change so
19:22I had another custom translator choose
19:25input program changes input and also
19:28output and wrote this to channel 16
19:33now all the messages coming from coming
19:38into this channel or wrote it out of
19:40this tract the node signals are altered
19:45to channel 2 but all the other signals
19:50I wrote to channel 16 which basically
19:57changes the instrument and its
19:59parameters we're almost done so you can
20:04see that we have two different
20:05instruments assigned and now I can
20:08change the instruments but there's a
20:09slight problem the sustain pedal is also
20:12routed to the main to the channel 16
20:15which basically suspends both channel 2
20:19and 3 simultaneously so let me try to
20:21simulate that suppose I have another
20:24part here and I filter out all the pedal
20:26signals on this plant parts this is
20:31firstly because through this part the
20:33pedal signals are routed to the main
20:35channel there's channel 16 and that
20:38basically suspends both both of the
20:41synthesizers so what I need to do is so
20:48these these apply to all control change
20:50signals but pedal is control chain 64 or
20:53I don't want to wrote it to channel 16
20:55but I want to wrote it to the actual
20:57channel 4 for each instrument
20:59alright so to do that we have to do some
21:02work I'm gonna create a custom
21:06translator with this pedal signal 64 and
21:10the outputs will also be 64
21:18and I'm gonna specify from which track
21:24it comes this pedal thing will come so
21:27this custom translator only applies to
21:30pedal signals coming from channel 2 so
21:33if it if it's on this channel this
21:36translator output signal so right now I
21:40want to wrote it to something like 6 and
21:44I want to make sure that this control
21:47change this pedal signal coming out on
21:52channel 6 is not translated to 16 by
21:55this translator so I'm gonna change the
22:00input channels of this translator to 23
22:04so what happens is when I press my pedal
22:07signal on channel 2 it goes into this
22:10translator this translator changes into
22:12auto channel 6 and now this translator
22:15doesn't do anything to that signal
22:17because it only changes signals from 2
22:19to 3 and after I pass this translator I
22:22have to add another one change that 6
22:25back to 2 so I'm also choosing channel
22:3264 control change 64 row 2 to 64 and
22:38this time it's gonna convert 6 to 2 so
22:47this is a long list of translators which
22:51basically wrote the channel so this is
22:54kind of a trick that allowed me to skip
22:57this translator for pedal signals it
22:59changes the 2 channel 2 to 6 and I'm
23:02back to 2 on this translator
23:04so basically skips this part 4 in other
23:09translators and I have to do the same
23:11thing for channel 3 so for example let
23:13me quickly do that and this time I'm
23:17gonna change 3 to let's say 7 and at the
23:22end I need to change it back to 3
23:27so now my pedal signal suspends the
23:36distracted solidus but when I select
23:43section the pedal only suspends this
23:46because the food the federal signals are
23:49filtered on here
