Ribbet!

The Leapfrog VCF does not actually go "ribbet," at least not without some effort.  But after being told by one friend I showed it to that most people don't want to make real music on their modulars but just want something that goes "uuuuuuuuuuuLAAAAAAAAAAAAARGH" (which, let's face it, is true), I've added a demo highlighting that.  Uulargh?  Yeah, we've got this.

Totally tubular

It's just one thing after another with the Leapfrog.  I'd been hoping to have them for sale by now, and I am getting close to that point.  I actually have the stock of the first batch on hand and ready to sell now.  But there's still a fair bit of writing to do on the manual, final checks to make sure all the drawings are up to date, a press release to write, and so on.  I'm working on an ambitious demo track with about 20 different multitracked instrument sounds all made with the Leapfrog, and that's taking longer than I had planned, but I'm learning a lot both about the Leapfrog and about synthesis in general doing it, so I thought it would be fun to go through one of the patches I'm using.  The score calls for (General MIDI) "tubular bells"; here's my take on a sound something like tubular bells made with the Leapfrog, and some notes on making bell sounds in general.

Temperature compensation with NTC thermistors

The panel contractor says they dispatched the first production batch of MSK 007 Leapfrog VCF panels to me on Friday, and those are the last remaining physical items needed before I can launch the module; so I'm still hopeful that I can aim for a launch by the end of the month.  That means I need to finish up the last few documentation items; one of them is a description of the exponential converter temperature compensation circuit, and that's an interesting enough item to be worth a Web log posting of its own.

The Celebrated Leaping Frog

I've spent most of this week working on the third prototype for the Leapfrog VCF.  I'm hoping to have this available for sale by the end of the month - maybe in time to have some kind of spooky Halloween tie-in for the launch.
