I once built an intruder alarm for my house using 555 timers, I've never once considered using one to make music :) Yes, that final sound was pretty awesome, I think the secret to creating square waves etc, would be in the capacitors, at a guess.

You are unlikely to get "pure" square waves out of a 555 due to component tolerances.

@@SpeccyMan It's actually impossible to make a pure square wave as it would require infinite bandwidth.

That makes a lot of sense, actually. The initial waveforms looked like the derivative of a square wave (big upward spike on the rising edge, close to 0 in the middle, and then big downward spike on the falling edge). Adding capacitance is akin to integrating the signal, so you essentially recover the intended square wave!

I used to teach electronics. I can help you understand the 555 if ever you need to

Can you explain it to me?

This reminds me of my first attempt to create a synth sound. I used a CMOS chip to generate a square wave, which I tuned and sampled. I used it in FL to create my first musical sequence. I added some electric guitar and drums. "Electric Texas " was born , a bumper used on the Kevin Smith show for years.

David - You inspired me to make my first simple test Kontact instrument with samples from my Moog Little Phatty,

The end result was pretty damn awesome! Remember what Bob Ross said. There are no mistakes. Only happy little accidents.

this turned out very beautiful, as always, thanks for making these videos!

Thanks for this - it's helped inspire me to make my own instruments.

The Pad in this instrument is top notch! Thank you :)

wow can't believe you just made a really sweet synth from a basic arse 555 circuit. Amazing

wow. this just unlocked a whole new dimension for me. thank you

Great video, I had never seen a ‘naked’ oscillator, nice work and very decent sound out of this DIY project. Thumbs up 👍🏽

now that’s what i like about circuits and music

If you were ever planning on revisiting this experiment you'd be better off using a cd40106. The circuit only needs a single capacitor and a single potentiometer and it sounds way cleaner than the 555.

Hi, so I am creating a synth like this for a school project and was wondering what is being used for the input jack? I am familiar with guitar input jacks but not so much this. Was this just being tested out on a regular speaker or straight into a computer? I ask since I need proof that I am not only testing it but it works

You are great man..thank you for sharing your ideas

You make fantastic videos! Thanks so much.

I built a whole synth around a hex Schmidt trigger. 40106IC. I love this circuit!!!❤❤❤ Thanks for the instruction!! In the future you could hook the output up to a speaker 🔊, and put a variable resistor/pot, in the place of your fixed resistor. 😊😊

this is really cool, good job!

You have a "weird" waveform representation, but a stable harmonic representation because you have some kind of a phase response alteration. 04:01 for example, this wave is supposed to be "saw", because every harmonic up to your Niquist is there. But it doesn't "look like a saw" because if you shift phase for just one (or a bunch) of your harmonics compared to others, you get this "not-phase-coherent" sum of its parts.

I'm in the same boat as far as building a bunch of circuits at a young age. Buying a synth is expensive since I only want to dabble in music as a hobby, but your vid is inspirational.

Thanks Dave!

This is awesome 😃

i love your channel

Very cool. Subbed.

You gave me an idea, it could be possible to check the accuracy of a 555 frequency by comparing the audio tone with a computer generated tone of a known frequency. This only would work if the frequency of the 555 timer was in the audible range.

@tshupenia8940

You could also hook up something called a snark tuner to the output of the speaker. They’re tuners typically used for guitars, but they just sense the vibration of the frequency and clip right onto what ever you need to tune. Not sure exactly how accurate this would be, but would save a lot of time.

Interesting, I don't remember saying that. Seems kind of silly now, I think 555 timer frequencies are very accurate.

Is it normal for the 555 to explode? J/k but the rails are reversed on the schematic than my breadboard, that screwed me up

Might need an LFO for the lower frequencies

love your videos, you're a genius!! thank you for this! ,,,,,,,,,,,,,,,,,,,,,,,,one thing could you zoom in on the things you're writing and/or working on.? my screen is tiny. cheers from Iceland.

Cool 😎 Thanks

It's funny, as a software engineer I'm _allergic_ to having computers anywhere near me if I'm doing something with music. Watching you switch to spreadsheets while making a synth is just painful! 😂😉 Let's see if you ever finished this synth, did you make a filter yet?

Fun thx 😀

i wonder what happens if i mix the kontact library with the mozzi library... just asking

What resistance does the potentiometer for controlling the frequency have?

I think the "analog sound" that people refer to is the output stage construction, transformer, etc.

Lots of filtering with transistors and diodes etc. Not too many actually. There are some really great videos using Hex Schmidt triggers.

Very well done videos and great explanations, above super inspiring to creating instruments myself! So thank you and pse keep on! P.S. your note number table looks like slightly shifted, shouldn’t be 440 Hz/MIDI number 69 be A4 in English notation instead of A3?

According to ISO, middle C is in octave 4 - so C4. Therefore the A above it is A4.

If possible, can you do another sfz instrument creation tutorial? I watched one you did and it was awesome. I like the ones you do with Kontakt, but unfortunately I haven't the finances to invest in the software.

wow

please try the atari punk console

...I don't think I'd really consider that analog...am I wrong?

how about a sampler, ehh? EEHHH?

You're using Ableton why not use the built in sampler

I hate the way schematics look, they're so confusing. I prefer breadboard diagrams. By the way, the breadboard diagram creation software is called "Fritzing"

wheres that sheet tho lol

Seems like an incomplete Atari Punk Console.
