Best explanation I've ever heard! Thank you!

[@RunningonairMusic]

Thanks for the feedback!

[@DaveHoskinsCG]

If you use sine waves with ring-mod you can make great bell sounds by pitching one sound exactly 5 semi-tones away from the other.

[@RunningonairMusic]

2 sine waves and ring mod? You should just get another 2 sine waves out. Which synth are you using?

[@ldmdesign5610]

@@RunningonairMusic I get a usable bell kind of sound doing this on the novation circuit. not sure i go with 5 semitones, i think maybe i found 9 was useful. could do with more partials of course that you would get with FM, but still it's not bad

[@RunningonairMusic]

Interesting.

[@AddlerMartin]

2:58 FINALLY someone explained to me what FM modulation is. THANKS MAN :D

[@RunningonairMusic]

Glad it helped.

[@J1M0TEE]

Cheers! This was a great vid. Sometimes it helps to understand the underlying maths and physics and electronics etc of what's going on. Time to go noodle around on my synths! :)

[@RunningonairMusic]

Glad it helped!

[@gkillmaster]

very excellent. Thank you!

[@RunningonairMusic]

Thanks!

[@TylrVncnt]

Love your music

[@RunningonairMusic]

Thanks.

[@JAKSN-youtube]

now i know. thanks a lot. 😃

[@RunningonairMusic]

You're welcome 😊

Good video, Playback speed at 1.50X recommended.

[@RunningonairMusic]

I'll try that.

[@TheBjarne48]

Great video! Having a bit of trouble understanding how you use the mixer at 15.08 in order to open the spectrum? So, if I understand correctly you are feeding the channels iteratively for each mixer input? So for input 1, you use carrier1+modulator1, and for input2 you use output1(from input1) + modulator2, so that in essence you are using 4 modulators?

[@RunningonairMusic]

I'm just using the mixer to boost the level. This in turn generates more harmonics from the carrier.

[@TheBjarne48]

@@RunningonairMusic I see. This may be beside the point of the video, but why do you need 4? How come 1 doesn´t suffice?

[@RunningonairMusic]

OK, so the key point is that I just needed a quick and dirty way to get amplification of the modulator. This was the solution I found. Each stage gave 6dB, but by using every stage chained together I could then get 24dB. If you watch the video again. you can see how each stage set to max increases the amount of modulation and therefor the number of harmonics output. Ideally a single amplifier module would have been used. Hope that clarifies it.

[@TheBjarne48]

@@RunningonairMusic Thanks for the explanation!

[@dzogten]

sometimes the sounds you're generating are harsh such that I had to lower the volume of the video (e.g. 14:02) which of course lowered the volume of your voice to the point of unintelligibility. I suggest using lower volumes for harsh sounds in future so that the viewer needn't resort to attenuating the volume of the video and can continue to listen to and understand what you're saying throughout.

[@RunningonairMusic]

Thanks for the feedback. I'll bear that in mind for future.

[@FastusMusic]

@@RunningonairMusic ducking with a compressor can work well too

[@RunningonairMusic]

@@FastusMusic yeah, I think it was just a case of me getting used to the sound while I was working on it. Still doesn't sound too bad to me, but it is something I'll try to improve for everyone else.

[@Omer-kp4fe]

Thanks great! what is the oscilloscope you are using?

[@RunningonairMusic]

Thanks. If you put "oscilloscope kit" into amazon you should see it.

[@user-gq2yj8uu7p]

Carrier frequency is always higher than modulating frequency

[@RunningonairMusic]

You can have them the other way round as well.

[@dawvideokanal7369]

could you explain phase modulation?

[@RunningonairMusic]

Hi, yes i am going to look into that a bit more. If I can find a good enough explanation, I'll do a video about it.
