Hi Jesse here from Altered State Machines. Thanks for the kind words about our module. I saw you mentioned you might make a video on Mod Wiggler the other day, so when I noticed a flurry of activity on the store today, I wondered if this was why. I have a couple left in stock now, thanks to you, but I'll fire off an order for 30 more this week and they should be in first week of September. Cheers! By the way I'm currently working on an 8 channel looping deterministic voltage sequencer and will have a Matrix mixer in the shop by the end of this month as well. Busy busy.
Yep! Very similar module. I wasn't aware of theirs at the time I designed DAC but people have pointed it out since. I think Tonic has adjustable intervals also?
Tom, really enjoyed learning about these modules. I love interesting sequencers, so this is definitely on my radar as well as the DAC. A little unsure if that unique filtering VCA would be my cup of tea, but It was really nice learning about it.
Fantastic video! Aristotle is similar to some fractal sequencers I've built on Teletype but it's so clever and unique. That DAC is a wonderful idea and that VCA like...what??? If I understand correctly it's kind of like an ADC into a PWM DAC but with all the internals (filter, frequency, pulse-width) exposed. It'd be really interesting to try something similar with delta-sigma encoding. 👀
Thanks Eris! Yeah, the cDVCA is wild - such an interesting design. The sound is like nothing else - a bit like a combo of sample-rate reduction and clipping distortion but not quite the same as either. I like using it with simple waves going in but it can do disgusting things to drums 😀
Hey, thanks for the kind words! The cDVCA is entirely analogue no ADC/DAC in there, it converts the sounds into a PWM by comparing the input signal to an ultrasonic triangle wave. The distortion is quite interesting in the sense that it works be reducing the amplitude of the triangle wave thus appearing smaller in comparation to the input and encoding the higher PWM values. So its actually more like clipping than overdriving. There is a bit of confusion online about Class D. It's often refer as a digital amplifier but that's in the sense that is turning the sound in a on/off format however many application of this tech does not involve any sort of processor at all. Delta Sigma and Class D are actually cousins in the sense that they encode the sound in a 1bit format (On Off). Basically both of them would encode the voltage as an average of on and off times over a set amount of time. The main difference is that Class D is an entirely analogue circuit while Delta Sigma is a way of encoding analogue voltage to be used digitally. I'll stop nerding now. Have a great one!
