/ EXP-1

EXP-1 is an expander module for our analogue Eurorack oscillator VCO-1. It adds an LFO with two waveforms (square, triangle) and various modulation targets, sync, lin. FM, wave morphing, an additional triangle output etc. Together with VCO-1 it is a complex oscillator with lots of internal or external modulation possibilities.


DIY level: Medium. The EXP-1 DIY kit can be built by medium experienced DIYers in about 2-4h.


Building Instructions can be downloaded later via Exploding Shed.


Availability: Besides our workshops, EXP-1 is available via our online shop Exploding Shed from september 2018.


LFO Freq. ca. 0,01Hz - 200Hz

LFO Amt. (target via selector)

Lin FM (int. LFO / ext. signal)

Morph (int. offset / ext. CV)


LFO Shape (Saw / Square)

LFO Target (Morph / PW)

Morph Mode (Tri-Spare / Tri-Saw)



LFO Freq (ext. CV influences LFO Freq.)

Lin FM Input

Morph CV Input

Sync Input

LFO Output

Morphed Output

Triagle Output


Powersupply: Like all Eurorack modules, the EXP-1 is powered by a symmetrical power of +/-12V. Additionally it is connected to VCO-1 via ribbon cable.


Additional Info: Unlike most DIY manufacturers, we produce our panels and circuit boards in germany. We also only use quality materials and durable parts. We hope that our customers appreciate and support that. The frontpanel was designed by Hannes Pasqualini / Papernoise. The VCO was developed for us by Leshracs Lab.
