I actually did this months and months ago but never thought of posting it here (I only just became active again on these forums). After messing around with custom VRC7 patch settings, I ended up with something that kind of sounds like a 50% square wave.

I thought I'd post it here, see if anybody is interested.

Ha, awesome! I'm actually in the middle of composing something for VRC7, and was wondering how to make a 50% square facsimile! Thanks for uploading this. I wonder if it's possible to emulate the other dutys in VRC7.

Squarebells sounds real nice, love the ninth chord strum at the end.

You're welcome!

I doubt it, because the VRC7 uses sine waves as waveforms, and you can't just chop part of the wave off, or else you get an entirely different sound. I don't fully understand how it works, but I'm pretty sure you wouldn't be able to get a 25% pulse wave with FM.

You actually have it right on the ball, jrlepage.

A regular sine wave typically follows a 50% duty cycle. You'd have to modulate a sine wave's frequency in order to change this, but you'd also have to overlap another wave of a different frequency (this will either cause dead pints or over-amplified points in the total summation wave). Then, you can send this summation wave to cut-off in order to produce something along the lines of a square wave with a duty cycle other than 50%.

Cheater! I can do it too, and I don't need your fancy VRC7. x)
