[0:00] so i like all pass a lot sometimes i'll have like you know one bass that's like a low pass and then like another bass that's like harder hitting in like the chorus or something where i really want to like you know really want more power then i'll do i'll have like an all pass base so and then you just have low cutoff and high q yes depending on you know where you want the signal to boost because like [Music]

[0:33] i mean like that's pretty cool [Music] you really get that like the third the major third so it's this is like when people talk about there's a video out there called the ghost channel and it's like the idea that you can have extra notes in the wave channel it's really talking about this overtone emphasis that sounds like almost two notes

[1:08] because you've got the low note but then also that octave that's like two octaves above or three if you use all pass was q boosting that fifth the power chord and also clip does it ever sound like a guitar power cohort with distortion or does it just get too messed up to hear anything so yeah that's a great question um it kind of depends i guess like so like sometimes sometimes i use low pass and sometimes i use all pass because um all past having more of the

[1:43] harmonics in the upper range does mean that it makes for like a sharper sound because you're like retaining the kind of like edge sometimes i really want the fifth to come through and i kind of want to filter that stuff out so like i'll just set it to low pass but like let's take a listen here uh let's see what our waveform looks like oops i need to make a cue i need to make a high q oh yeah gotta put this back on manual three two one okay so this is like your

[2:15] waveform this is like pretty maxed out on both the volume and the q um let's set this to manual also in this version it's kind of nice because you can actually choose exactly which waveform you want in manual instead of just the synth so that's kind of nifty i just thought i'd point that out i hear that there may be a version 893 in the works uh okay so anyways let's [Music] do i do i hear the fifth in that like

[2:53] kind of but it's kind of subtle so like i want to boost the cue a little now i hear it i think that's maybe too much so maybe somewhere in between here okay so maybe somewhere around eight or nine for that [Music] i kind of like that like version of it um just for kicks let's or for bases let's just do this kind of thing where it's like

[3:26] e01 like i want to hear what it kind of sounds like to like hear it in action a little bit so like we're basically i'm gonna basically turn it down halfway like a little past halfway through the note and then turn it back on to get like this kind of da da da da that might even be a little too like drastic let's see [Music] or you know you could even go okay so that's like kind of a cool sound

[4:03] like that's almost what i would think of like as like a fast power chord kind of thing so now let's change it to all pass and like see looks a little gnarlier not as clean you know a little different so let's see what it sounds like now like it's honestly pretty similar um um so like it doesn't necessarily to me sound like you know a true real power chord i guess we can also try to boost you know like we could just keep going nuts

[4:37] oh now see that's that's pretty wicked like does it sound like a guitar chord [Music] i don't know if i would say you know guitar chord it doesn't not sound like a guitar chord but you know the uh let's see now let's go back to low pass with this like crazy volume on it and see what happens

[5:10] so i don't know that's those are about the range of sounds that you can get with it for so like i don't know if i would say it sounds exactly like guitar power chord but um it can be effective if you really need it especially once the cue starts to get up here i think the nice thing about the all pass is that no matter how much you boost this cue you really never lose the root note so like i would probably see is that what you asked yeah you asked for all

[7:01] you
