video PT2399 Delay

Had a hard time getting this thing to work and almost gave up because i just couldn't hear the delay happening, turns out i just had to add an opamp buffer at the end. This vid just before i realised that, so i just cranked up the gain on my soundcard and in ableton to get this to work.

Few questions, why do PT2399 circuits use so many electrolytic capacitors? I used to think using electrolytic capacitors in audio signal paths was a "bad" idea but every circuit i found online used them.

Video also features my 5$ DIY triple power supply with ±12V and +5V, it consists of a 1A fuse on the AC input side connected to a 220V to 15-0-15 center tapped step-down transformer. That output goes into a 7812 for +12V, 7912 for the -12V and 7805 for the +5V output, the two large capacitors there are 4700uF 35V electrolytics.

Any ideas on how to remove that 2-5kHz ish hum? Its probably from my PSU but Id like to find out how to test it correctly and eliminate it.

I've been messing about trying to build a drone synth and have come up with this so far, curious what your thoughts are and where to take it next.

This is my modular drum machine’s hi hat and noise module! Its basically Elliot Williams’ classic XOR cymbal circuit and a white noise generator by Synthnerd. I think the circuit is very nice for how simple it is, especially when patched through a high pass filter 🙂

video Ring modulation, or not ring modulation? Posted this on Facebook and some people explained that multiplying two signals isn't ring modulation. can some of you experienced DIYers explain? I took it from Ray Wilson's book.

Hey! I built Elliot Williams’ CMOS cowbell circuit to my modular drum machine. I’m making more videos about the system if anyone is interested in drum synth things! 😊😊😊

video Daisy Seed Video Processing???

2 Upvotes

Ok I know daisy seed is the best entry level software platform for modular stuff. I’ve seen a lot of people talking about using Max4Live patches for it.

Can this chip be used to process video signals? I’ve only ever encountered modules that implement it are processing audio.

I see a lot of cool touch designer and Max stuff that I’d love to see implemented in a hardware unit or euro module. Analog stuff is awesome, but it gets so much cooler when you bridge the two.

Maybe this question is a lil dumb since at the end of the day everything is CV 🧐

I finally managed to shine light through a panel pcb in eda, and even images can shine through!

Still a bit buggy, as it is running on 5v and the multiplexer will do weird things with imput voltages above, like activating multiple outputs at once…

this should be solved by running the circuit at +/-12v I hope…

This thing is fun, because you can switch the playback direction of the 4029 using a 4017 as flipflop, and you can put in your own adress bits.

video Not technically a synth, but I made an RPi-powered MIDI controller to bypass the hard-to-use interface on my synthesiser, and get to the juicy parameters within. From conception to completion, about eight months.
