Here's the first demo of monotron-squared, which is very close to being complete and tempting to keep playing in its current (not-quite-finished) state!
Note that the square wave-shape circuit is engaged, and the only pots I use hear are cutoff, resonance, LFO rate, LFO depth, PWM, keyboard tracking depth, and the pitch range (1Meg-ohm) that drives the second VCO from the first (see previous posts).
Also, the 1Meg pot is not grounded (case wise), so I only touch it for some buzzy interference effect...
More to come.

ReplyDeleteStill working out a few kinks, as linking 2 units is not as easy as I first thought! Sounds much juicier with both VCOs though, ey?!?
I am going to try and add an envelope to the cutoff input - by copying the design of the Gakkens' envelope, using a 555 timer.
The Gakken was alot easier to mod 'physically' since all the solder points were a bit bigger, whereas the monotron is way more compact and has a tighter layout (even though both the Gakken and the Monotron are all surface mount devices, the Gakken is a cheaply produced unit).
anyway, I love the Gakken, its rough and dirty sounding, but the monotron sounds a bit more stable and clean, and a the filter is really nice.
Both are noisy, but cheap and fun to mod.
Check here for the Gakken mods I did:

and get modding.
also, if you don't know, check out this guy's blog - its where I started with the basic mods for both the monotron AND the Gakken (his vids on both are great):
