Very excited by this: morphing wavetable synth in CircuitPython!
https://www.youtube.com/watch?v=4hgDi6MNfsI It's still rough around the edges, but is sounding _really_ cool. Since it's wavetable-based, swapping wavetables gives the synth an entirely different character. (did you know of this awesome set of wavetables?
https://waveeditonline.com/ Just drop these WAVs in the CIRCUITPY drive & get new sounds) All on a little QTPy RP2040!

Wavetable synth w/ CircuitPython synthio on QTPy RP2040
I've checked the BOM and it seems like Bassline has some unobtanium parts in it :( but I'll still try to pull it off when I finish my current projects
Have you tried building any of these? Bassline looks tempting

it does nothing 😅 I just forgot to remove it from the sim
you mean like power it with 0+5v? I think it won't work with negative input voltages then, right? and I'm using tl074 and I'm not sure that 0+5v is enough juice for it, and I use remaining 3 opamps for other stuff, so it's not really an option for me. the sim didn't have shottky diodes, so this measurements are not 100% accurate, but I used this approach to protect arduino inputs in another project, and it worked well. And yeah, I cranked up the input signal to +/-10v just to check the clipping, it'll normally stay within +/-5v
I already ordered PCB for the prototype. I hope it'll work fine. Thanks a lot for your help :)
On a free side Venom VB-303 sounds good, but is painful to use
I'm usually using the one from IK Multimedia Syntronik. It's a little heavy, but sounds nice. I don't think I ever payed for it, they were probably giving it away, or it was bundled with some midi controller, idk
maybe something like littlebits kit? I haven't tried them myself, but they look fun, educational and kids friendly (not sure about 3yo thou)

Busy week. I've been stuck making a new revision of eurorack module I'm working on, but also found some time to visit a friends studio and refine a mix of a track I'm hoping to release soon. So, some exciting stuff coming soon :)
No, with 0 Ohm I get a perfect 0+5v sine, just as I need. It's the other way round, it'll amplify the signal and clip off the top at about + supply voltage when you increase the resistance in the feedback loop, but it's not exactly square wave, as the bottom part of sine will remain intact. I use clipping schottky diodes to protect the arduino from voltage outside 0+5v range, this way if you increase input signal to say 20v peak to peak, you'll get more square-ish wave in 0+5v (I've attached the schematics)
