Thanks for all the support, as the above is how i keep this project afloat, as i don't think i'd be able to develop projects like the furby organ and gameboy mega machine otherwise so thanks! :D.
Im giving away 5 component packs, and a DIY modular furby i built on a livestream a week ago, on my patreon next week! so if you want any of that go check that out!

@TROGULAR10000 5 лет назад

his band in which he plays guitar would have seemed 100% normal in the eighties. I often wonder what his parents look like or listen to. maybe they listened to 60's music in the eighties and then he was born in the 90s, so there's like a lag. or it's a cyclical thing and all styles are bound to come back which is why I'm being subjected to the eighties for the second time (although this guy is totally amazing and funny). there are so many retro bands now. so you can imagine a musical universe that supports all periods simultaneously. but in just a few more decades, assuming one style per decade, it's pretty far out.

@SamiJumppanen 5 лет назад

There's approximately one word to sum this all up: brilliant! I am going for 1V/octave because there might be three parts (MIDI-CV-MIDI, analog sequencer and the synth part obviously), keeping it standard. Always say "never", I'm not going modular, I just want an analogue mono synth with as low expense as possible.

@sinsofourfathers 6 лет назад

I've been waiting so long for a series like this. No knowledge on electronics whatsoever, but with videos like this I'm willing to try. Got yourself another patreon! What tier gets the additional information of the extra features?

@illnessofjeez 4 года назад

MODS: ok so i put another 100k pot in series with the tuner pot, and now i can tune a much wider range; whereas I was able to find middle C and tune to that now. :D, i got the tuning pretty tight now, i can span more than a few octaves and remain in tune :D so pumped I used a BOSS TU-3 on chromatic using middle c and checking in the DAW with another voice layered over top. cheers

Been looking for a video like this for weeks. You've got to be one of the best guys on RU-vid. Any way to get a square wave?

@LOOKMUMNOCOMPUTER 6 лет назад

yep like i said in the vid, i will be adding addons to this circuit, this is the core of the module, ill be including optional addons. square wave out + PWM in will be one of the add ons, only requiring another TL072, 10k resistor and a couple of jack sockets. i still need to finnesse, but you can definitely work it out if you look at the CEM3340 datasheet :)

@emilcarr7190 6 лет назад

The add on is pretty simple, a comparator on the triangle out (saw might work too?) and the width is chosen by changing the voltage it's being compared to

@LOOKMUMNOCOMPUTER 6 лет назад

its even easier, check the CEM3340 datasheet, it already has square wave out, i just figured it would be a simple addone with 1 tl072 for input and output

@marizuokereke7347 6 лет назад

If we are planning to do the add-on's, would it be worth putting a tl074 in now instead of using two tl072's?

@LOOKMUMNOCOMPUTER 6 лет назад

yeah totally. would be an option later on. this just seemed easy for now, but yes. totally. when i do the square-wave one ill plop a tl074 stripboard layout in too
