Casiomojo MT-100 is the big brother of the Casiomojo MT-35. It's a synth manufactured in the 80s featuring 20 patches. Not all patches were recorded through the exact same chain, but all of them went through a custom console designed in the late 50s (tube, of course), nice preamps, and nice tape recorders.
The interface features effects and controls ranging from pitch shifting to tremolos, phasers to attack and release, chorusey double tracking to digital and impulse based reverbs. A user can also combine a number or patches to create an unique sound.
Price: $30. It can be preordered for $15.
