Hello guys
I wanna build oskitone poly555, cause its so cool and polyphonic
And since im noob, can i connect it to single voltage lm358 based vcf (schematic by Pete McBennett youtube)
Oskitone poly555 schematic layout
Oskitone poly555 chip
PeteMcBennett vcf
Also in the PeteMcBennett vcf schematic above, where do i connect “trigger pulse input” into oskitone poly555 ?
I dont own this great schematic, its belong to them.
The schematic owned by amazing oskitone team and their management , and Pete McBennett.
Bless both of them for providing these awesome schematic.
I really thankful for the help,
I kinda stuck with my reverse oscillator project
And i hope this time it would work.
Thank you

I don’t see why not. It’d go after the oscillators and before the 386.
That’s a problem. The trigger pulse input is supposed to be generated by the keyboard or sequencer that normally would be used to control a single oscillator. Instead you have an individual gate for each of 20 oscillators. In principle these could be combined with a logical OR, either with logic chips or just diodes. Not sure how tricky that might get with 20 inputs, though.
Or you could generate a gate manually (or with a foot switch).
The result’s going to be (more or less) paraphonic rather than polyphonic. That is, you can produce multiple independent pitches simultaneously, and they can start and stop independently, but the same filter and envelope will be applied to all — so all pitches will respond simultaneously to the filter envelope.
