Modified Casio HT-700

"I modified my Casio HT-700 minikeyboard. This is the programmable version of the MT-600.

It has two onboard analog filters, one for the main voice and another for the chord voice. I never liked the chord stuff, but the programmable bass voice was quite usable, so I routed that through the chord filter and got rid of the chord channel.

I added CF & res controls for the filters, as well as triangle LFOs, a simple EG for the bass voice, and octave-dropped the bass voice. You can also route the drums through the bass filter, and I added a modification that defeats the annoying AutoPowerOff "feature" of these keyboards.

Since the drums and bass are programmable in two-bar loops, this thing is now a nice little groovebox, over which you can play melodies."
