Yet another electronic doohickey
Added 2019-06-22 16:03:45 +0000 UTCKnobs are standard on Eurorack sequencers, because there has to be a way to set the voltage value of each step. Some even have sliders for this, but .. buttons you guys! This one has buttons! It's also 16 steps; most rack sequencers are only 8. Built-in quantizer greatly simplifies tuning, and I don't have to waste my quantizer module on it.

Oh, i did not wish to ask you the technical details, i was asking if you could do a video that highlighted these imperfections.π€ππ It's one thing to think about it in an abstract way, it's another to actually hear them.

2019-06-24 06:57:37 +0000 UTCWell I don't understand the electronic principles behind it, but ... Anything with an attenuation knob is going to be imprecise because you can never set it to the exact value of the input. At 1v/octave a slight difference will put your oscillator out of tune. Audio mixers do some sort of averaging rather than adding voltages .. there is "unity gain" mixing in which the output is the same level as the input, but if you have two signals peaking at 5v, the mix output will still be 5v. With an adder, when you plug in two 5v signals the output will be 10v. With the passive split cable you would get "loading effects" based on the impedance of the outputs (which are "pushing against each other" when directly connected like this), and I don't think the voltages would be added correctly.
2019-06-24 02:05:02 +0000 UTCSo, with normal mixers you can hear the inaccuracies, and a passive adder like the split cables would have a chance of damaging the input if not properly handled, right? Just trying to understand, sorry for the ignorance.

2019-06-23 14:14:32 +0000 UTCA simple adder would I guess be a mixer? Is there a certain margin of error involved in those circuits? The Doepfer precision adder is built for combining pitch CV so the output is precisely the value of the input voltages added together. It has to be precise because it is controlling the pitch of oscillators, and any inaccuracy is going to be audible right away.
2019-06-23 13:55:54 +0000 UTCWhat's the difference between a simple adder and a precision one? π€π Anyway, it was interesting. Thank you for this... i suppose it should be called: live test. π€ππ
