 Hey, it's Anfa, you're watching quick request with pure black screen, green screen effect. That should look very weird. Oh, it doesn't. I was asked the question in a YouTube comment under one of my videos. How do you filter MIDI notes so that from a single MIDI track you can drive multiple tracks where you have synthesizers making drum sounds if the synthesizer doesn't have a MIDI note filter built in. So in that video I was using a ZinatsubFX to basically get MIDI data from one track and then respond to only specific note for each track of the drum kit and then each track would play kick, snare, etc. And the ZinatsubFX synthesizer has a MIDI filter, a MIDI note filter, so you can say which part of the MIDI keyboard the synthesizer will respond to. So you can limit that to a single note. So when you play on your keyboard, all the synthesizers are receiving all MIDI notes you play, but they filter that themselves and only play each one on a single key. So you have a kick, a snare, and a hi-hat, etc. Helm, for example, doesn't have such something like that, and many synthesizers don't have this functionality, actually most don't. So in this video I want to show you how can you do that with a MIDI filter plugin. So the first thing is we need some drums. I'm gonna create three Helm instances. I'm gonna call this Helm. These are MIDI tracks. We could actually use MIDI buses because we won't store any MIDI data on these. So these are just our presets. You can't really make a clip here because this is not what we're gonna do. We will have just one MIDI track and this is gonna be the drums. Yeah, and just a single MIDI track. So now I will make this track. Let's do this. I'm going to go for the output from the drums MIDI bus rooting grid, and here we have in the rooting grid we have left-right audio channels and the first MIDI channel. So I want to feed that MIDI channel into outdoor buses and all three Helm will receive the MIDI input. So now if I put something here and you can see all three MIDI tracks play the note, sorry, that all three MIDI buses play this MIDI note because being fed to it to them. So now I'm gonna quickly make some drum patches so we can have three distinct sounds. Now I'm gonna make a simple pattern. So we will kick snare and hi-hat. Right? Now we want these three MIDI buses to filter this so the kick only reacts to note C4, the snare only reacts to note C sharp 4, and the hi-hat only reacts to note D4. Right? This way we can draw our drum pattern in the single track and then copy and paste that all we want and we don't have to fiddle around with all that stuff. We can just you know group it and hide it or something and we're done. We're ready to roll. So I'm not gonna make the patches now because they don't do anything interesting yet. So I'm gonna use a MIDI and we need to find a plugin that interests us. A MIDI filter. We have a MIDI channel filter. Well that doesn't do what we need. MIDI note channel map. MIDI notch. Oh, that's interesting. Well we can, well we could actually put this on our drums track here. Oh, we have an instrument here too. We don't want any instruments here. Right? Why doesn't it actually, why don't this make sound? Oh, because we have the output set to nothing. Okay, not sure why. Why is that? Cool. So MIDI note to channel. Okay, so we can basically filter every single note to a different channel. Well that would be one way of doing it. So we can cut this, paste it here and we can like have you know C which is kick to channel one, C sharp which is snare to channel two, D which is hi-hat to channel three. Right? And then we can right click here and use, okay we don't have this here. Okay, we can use a MIDI channel filter and then have only the, well that sucks because you have to click through all of that. It's just an eyesore. Okay. All right, so now I put this here. So now this should respond only to note C. Let's do this. And now I disable this, enable the second one. Okay, we have some success. Paste and now disable this and disable yeah, enable the third one only. Okay, the kick for some reason doesn't sound. This is enabled. It should be okay, right? Okay, oh okay because we have no master output for some reason. All right, so we have this. We have filtered the MIDI data basically by using two plugins. One is MIDI note filter, a note channel map by Robin Garrius. So this is the MIDI LV2, I think MIDI filter LV2 pack. I will link to that plugin pack in the description so you can download it. Basically we say all C notes go to channel one, all C sharp notes go to channel two, all D notes go to channel three. If we have more elements to our drum kit we simply select another subsequent MIDI channel number for each note and then we use that note for each instrument and then for the MIDI bus that listens to that instrument we need to insert a MIDI channel filter by Falk TX or any other MIDI channel filter and enable only the channel that is assigned to this instrument. So it is a bit fiddly but it could be a useful setup if you want to, you know, problem complex drum beats and have the control easy on a single track. So now I'm going to make some sounds so this actually sounds somewhat sensible and not just like a nonsensical, you know, part of Saative Waves and whatnot. So let's make a kick. Let's see if I can make a kick without listening. Hello? Well, almost. I'm gonna solo this. All right. It's not too good. Okay, that's better. Let's make a high pass and a tiny bit of noise. All right, that's a kick. This will be a snare. Let's loop it and again just a sign and we need some noise. A high pass. Pretty sweet. Cool. Now the hi-hat. That's a super simple hi-hat. Oh, this is... And there we have it. I'm sure there are different ways to work around this with different plugins but this is one way of doing it. So I hope this video was useful. Yeah, and thanks for watching. I hope you learned something. If you have any questions about this stuff or open source music production software in general like Ardor or Helm, the synthesizer, there are some videos I made about both. Actually a lot of videos I made about Ardor and some videos about Helm and other plugins. So check out those. And thanks to all the Patreons at patreon.com who helped me dedicate more time to do this stuff instead of doing other work because we all need to eat and I would love to share all my knowledge and experience and my passion with you so you can make some great music with open source software because I think that's just terrific that we have this software. Okay, thanks again. I'll see you in the next video. Bye. That was short.
