The x0x-heart is the heart of the x0xb0x, surgically extracted from the x0x to be transplanted into your designs. The x0x is a faithful replica of the Roland TB-303, complete with sequencer and DIN/MIDI/USB. The x0x-heart is just the analog section of the TB-303, replicated with SMT components, and made small enough to fit into a Eurorack modular format. It even has a Eurorack power header on it.

The x0x-heart is designed to be small, inexpensive, and a close replica of the TB-303. It is not a perfect replica - some sacrifices were made to keep costs down - but its pretty darn close. Of the original transistors that are still available, none are available in SMT, so all new transistors were used. The PMP4201/5201 matched pairs were selected, and use throughout. These have very similar characteristics to the 2SC2291 and 2SC1583 matched pairs used in the 303, but have better matching characteristics.
