Those, who know the traditional version of this effect may want to watch the video from 2.15.
My take of improvement my ol' Parasit Studio project - Into The Unknown analog mono synth.
I'm a big fan of employing Baby8 sequencers to work with envelope filters (have built 3 so far, incl. the favourite Snow White autwah that stays for good in my pedalboard).
Making long story short:
- Into The Unknown was built from PCB, had cv input onboard. Employing the sequencer is a fluent job.
- Hummingbird trem is AFTER the synth, in the same enclosure.
- Synchronizing the speed of seq. and trem:
Good news: I found out how to make sequencer and tremolo sync! This very morning!
Just feed the cable outlet from Hummingbird bipolar transistor Base (middle leg of 2n2646) to Baby8 CD4017 chip (14th leg), unplug the 555 timer as you won't need it now and voila!
Now you control the tremolo and sequencer speed with just one knob!
Enjoy the sound.
