Open Music Labs x0x heart (White Magpie)

 

The x0x Heart is the core of the famous TB-303, surgically extracted to be transplanted into your designs. 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.

This module 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 it’s pretty darn close. It also has no pots or controls, making it great for DIY synth building. All of the useful I/O points are pinned out, and as a special bonus feature, digital control is given for Accent, Slide, Decay, Waveform select, Cutoff, and Env Mod.
 

The main PCB is a fully assembled and tested SMT board — it’s the analogue heart of the TB-303.

The Pacemaker PCB and DIY Grayscale Eurorack panel can be assembled together with the x0x Heart’s main PCB for a complete DIY Eurorack module!

The full DIY synth kit includes the assembled x0x heart main SMT PCB, the unpopulated Pacemaker through-hole PCB, and all of the Pacemaker PCB and panel parts, including ribbon cable, power cables, mounting hardware and more.

**Based on customer feedback, all newly-built x0x-hearts from synthCube will have a filter cutoff CV modification implemented that improves the response of the Filter Cutoff CV Input at low voltages. This modification may be performed to existing x0x-heart Eurorack modules. The details are here. Also, synthCube can perform this modification to existing modules. Contact us for details.

Here’s a helpful thread on the muffwiggler forum: x0x Heart Thread

 

October 2020 Update: New Pacemaker PCB are blue PCB material with gold immersion finish.

NOTE: The unpopulated PCB is a very challenging SMT DIY build. Please do NOT attempt to build an unpopulated PCB unless you are confident and experienced in DIY SMT.
