Liquid HiHat Version 1.40.AVI

"Finally after almost 2 years, I've built one of Hexinverter's Liquid HiHat PCBs that he'd sent me. This time though, with modifications. If you liked the Liquid HiHat before, you might like this one more. :D
Mods / fixes include:

- 2 x Offset pots replaced by 300k from +V to the summing opamp, to allow +/-5V modulation for each of the 4046 VCOs
- Hexinverter's suggested switch for each 4046 voice to switch capacitors values between 0.01uF and 0.1uF
- INDIVIDUAL OUTPUTS for each voice! Switchable for 1 pair of voices output or 1 voice from each output

These modifications and fixes allow the user to have EIGHT different sounds coming out of the Liquid HiHat depending on how the 2 x cap. switches and the 1 x output switch are set!

In this video, I start out using the 1 output, showing how the 2 voices together sound with full modulation coming into each of them as well as switching both of the timeing capacitor switches. Then, I flip to dual voice output, switching the cap values again as well as bringing the modulations back in.

All of this was done without changing the frequencies of ANY of the 6 clocks! All the more sonic potential lies in there. :)

1 voice was going through a 2 pole High Pass Filter
1 voice was going through a 2 pole Band Pass Filter

Please do pardon my patting-self-on-the-back but: no other hihat in the world, has the potential sonic territory of, the Liquid HiHat V1.4! :o :)

I'll be posting modifications at the very least, to the Schematics section of my webpage at:

and possibly to my Facebook account.

I hope you enjoy. :)

Pardon again, but, I'm almost speechless at the sonic potential of the Liquid HiHat even more so with these modifications, than any of it's previous versions. :O

Finally - each of the voices were going through their own Voltage Controlled Amplifiers with each of them having Attack / Decay envelope generators controlling their amplitudes. 1 was set to imitate a 'closed hihat' and the other was set to imitate an 'open hihat'."
