EFM VCF 4622 Moog Taurus type Transistor Ladder https://electro-music.com/forum/viewtopic.php?p=452757#452757 Hi guys, I've built this filter (jbeuckm v.2) and I'm loving the sound. Unfortunately I'm experiencing a pretty low volume on output in comparison with my other VCFs.
There is something I can mod in order to archive an higher volume on output and mor ...

That is correct about the transistors.... mostly. Sometimes BJTs will work "backwards", just not as efficiently. That said, it shouldn't destroy them either.

Be careful with yo ...

Anyway, with the benefit of actually understanding the circuit now:

if you build it share how it sounds :)

I have not seen BCM matched transistors before thanks!

Very cool!

4017 Baby Sequencer Stripboard https://electro-music.com/forum/viewtopic.php?p=448606#448606 Although it might not be its intended use you could run it at a high frequency and use it as a custom wave shaper.
Can be nice if you use a VCO as the CLK but keep in mind that the output frequency will be a fair bit lower.

MFOS VCO, VCA and some others https://electro-music.com/forum/viewtopic.php?p=448133#448133 Thank you for sharing the layouts

I like the combination of logic functions you chose for your Analog Logic design.

Wanted to check that the inverters are separate from the logic not serial. So logic function outputs are not inverted.

Devil's Triangle Drone Sequencer https://electro-music.com/forum/viewtopic.php?p=447875#447875 if you add a pot after the capacitor you don't need the resistor anymore, but you could add an extra resistor in series to limit the maximum level.

In details, I’ve noticed:
1. The output level is lower then the input level
2. Passing through the module the sound loses part of the low frequencies
3. Turning ...

Real-world experience suggests YMMV. It ...
