I made an Air Space Invader synth version.
It takes the huge input signal that synths create, and is extra loud at the output too. I cleaned up the filter, added a little more bass, thought they'd appreciate that. Then I thought 'hey that might be good for guitar too!', but you know, it just wasn't as exciting to play through as the regular guitar one.
And the Igor socket - works with 5v CV in (as with the regular one too), but upside down - and I can't do anything about that. And there's definitely a 'sweet spot' where it works best... ie a large part of the control range doesn't do a great deal.
I demo'd it for real in a synth showroom, the whole time thinking 'but I'm surrounded by stuff that already does this waaaaay better!'
It's kind of ground to a halt. I just can't get behind it and tell people to buy it.
How does anyone ever make any synth-based things when there's a whole bunch of tech geniuses with no friends who already rule that field?
